Suggested January 2024 How To Tell Cpu Fan Direction?
The correct alignment of all the PC fans is crucial to cool down your overall system temperature. And some components may even start thermal throttling, giving you a lower performance than expected.
Besides this, your PC will also collect more dust if you set the fans direction incorrectly. Therefore, knowing which way the air flows from your fans is a significant piece of information that you can use to make your system perform better and last longer.
But first, let us see why the PC fan direction matters.
The PC fan direction is one factor that most beginner PC builders overlook when building a PC. However, if you make the CPU fans face the right way, you may see a drop in motherboard temperature and an increase in its efficiency.
The overall internal component’s temperature not only depends on their usage, but also on factors like airflow, internal air pressure and dust settlement. Dust settlement and airflow is a fairly common and easy concepts to grasp. So, let us talk about air pressure here.
When you insert the CPU fans, there are three possible cases of air pressure.
Positive air pressure
Negative air pressure
Neutral air pressure
Talking about positive air pressure, the number of intake fans exceeds the number of exhaust fans. This will result in the air to pass into the system mostly through a dust filter. And thus, the insides of your system will be fairly clean.
Positive Air Pressure
However, as the system does not throw out the air efficiently due to fewer exhaust fans, this may cause the system to trap heat, making the setup slightly warmer.
Negative Air Pressure
On negative air pressure, the number of intake fans is less than the number of the exhaust fan. This will create a vacuum inside the CPU case. Once this happens, air starts to flow inside the system through all openings inside the case, which means that the dust will enter through every opening and not only the dust filter.
Therefore, your system becomes dusty if you have negative air pressure.
Neutral Air Pressure
In neutral air pressure, the number of intake and exhaust fans is the same. This is an ideal scenario as the air will mostly enter the CPU from the dust filter, and the cooling is also efficient.
You can check the direction of airflow in a CPU fan in multiple ways. The stock CPU case fan comes with a plastic screw attached to it. When you attach it to a heat sink, the air will flow towards the heat sink, pulling in the air from the opposite direction.
However, determining the fan direction in most CPU coolers and case fans can be daunting. Here are a few ways you can check the CPU fan direction.
CPU Fan Direction
One simple way to determine the direction of airflow from the fans is by checking the arrows on the sides. The arrow represents the direction that air flows when the fan starts to spin.
The direction the arrow points towards is the exhaust, and the opposite is the intake.
However, not all fans have this arrow indication. If your case or CPU fans do not have an arrow, continue with the article to figure out the fan direction.
Another indication you can check is the X shaped on one of the two sides of the fan. You will see a line that goes across all the corners of the fan diagonally. Thus, making an X.
The side with no pattern is the intake, whereas the side with the X is the exhaust. However, all CPU or case fans will not have an X marking. Some will have a different pattern.
If none of the above solutions help you to determine the CPU fan direction, connect it to a power supply.
Connect the cable from the fan to the CPU_FAN header on the motherboard if it is a CPU fan or to the SYS_FAN header if it is a case fan.
Once you connect the fans to the motherboard, connect the board to a power supply unit (PSU) and turn on the motherboard.
Once the fan starts to spin, use light tissue paper to check the intake and exhaust sides.
If you cannot connect the fan to a power supply, you can always go to the manufacturer’s website and search for the product. The CPU or case fan manufacturer is usually written on the center.
Once you have the manufacturer’s name, search for the product. Some CPU fans may even have a user manual to guide you through the steps to connect it.

How To Tell If Your Wi
You may have installed the best antivirus software that money can buy and believe that protects you from malware or virus attack, but such threats can invade your digital space using the W-iFi network as well. Here are a few signs you need to keep a lookout for which indicate some unauthorized person is using your network with malicious intent.
A Decrease in Wi-Fi SpeedThe most obvious sign that someone outside your trusted circle is using up your Wi-Fi resources is when the speed of the Internet suddenly drops for no apparent reason. Your videos might be taking longer to buffer. Websites might be taking longer to load, and online games might be having difficulty operating.
If you feel your net speed has decreased, or your data packet is being used up much more quickly than usual, it might be because someone else has hacked into the network and is using your Internet.
Changed SettingsMost hackers operate by sneaking into the network system and changing the settings to facilitate the hack. Check for signs such as:
The passwords having been changed.
The signal frequency is modified.
Your screen cursor starts moving on its own.
Presence of Unknown DevicesAs the network administrator, you should have access to the logs which indicate which particular devices are currently connected to the network. If you are not the administrator, find out who has that authority, and ask them to check the logs. If you find that there are devices connected to the system which are unaccounted for, it could very well be a hacker who has managed to gain access to the network.
Antivirus Is DisabledOne of the first moves of a hacker who has gained access to a network is to find a way to disable the firewalls and other antivirus programs designed to keep malware out of computers. If you find that your firewall has been disabled without your knowledge, it could be the work of a hacker who has managed to invade your network.
Strange MessagesOnce the hacker has gained access to your network, the next step is to actually cause harm to the connected devices. You might start receiving strange messages which carry virus-infected files. These files are often shared on closed networks by a computer which is controlled by the hacker so you think it would be safe to open.
If you have the least suspicion about a message you received asking you to open an unknown file or program, even if it appears to have come from a nearby computer, take the time to check with your colleagues to find out who sent the file and confirm that they know the file can be safely opened.
New Programs on Your PCFinally, the biggest sign of a breach in security is the appearance of strange and unknown programs on your computer. These programs have been planted on your computer by the hacker and can do all kinds of damage, from leaking your personal information online to allowing the hacker to take over your device and use it to perform illegal activities.
If you notice a strange program on your PC that you don’t remember installing, do not open it under any circumstances. Find out as much information about the program online as you can, and have your antivirus program scan the files to determine if they pose a threat.

How To Benchmark Your Cpu With Cinebench
If you just picked up a powerful new CPU, like one of the Ryzen 7 family, such as the 5800X or 5900X, then lucky you! The best way to really put your new CPU through its paces is to benchmark it. There are various tools you can use, but Cinebench is the go-to for most enthusiasts.
In a relatively fast 10-minute test, Cinebench uses a unique image-rendering process that maxes out all your CPU cores, giving you the perfect picture of the power inside your PC. Its tests give you a far more accurate “real-world” benchmark reading than most other benchmarks which tend to be more synthetic.
Cinebench R15, R20 or R23If you look into Cinebench, you may find there are a few different versions floating around. For all intents and purposes, the latest version (R23) is the best one to use. It’s the most accurate tests, has new features, like easily testing single-core performance, and will automatically disable itself if your PC doesn’t have the required RAM to run it.
So stick with R23, and let’s crack on.
How to Use Cinebench R23Once you’ve downloaded and installed Cinebench R23, it’s time to start benchmarking.
With Cinebench R23 open, you’ll see it’s a little different if you’ve used previous versions. The default options at the top-left corner are now a Multi Core and Single Core test. Also note that due to the new algorithms, benchmark scores can’t be compared with previous versions.
But before you do this, you should set up a way to measure the temperature of your CPU during the benchmarks. This is important, as the benchmark will put your CPU under a lot of stress, and you’ll want to know it’s not overheating.
One of the more accurate tools for measuring CPU temperature is HWiNFO, which is generally a great tool for keeping an eye on all the moving parts inside your PC.
Once you’ve installed HWiNFO, open it. (You can check the “Sensors Only” box.)
Take a look at the “Maximum” temperature in HWiNFO64 to see how hot the benchmark gets your CPU running. Maximum recommended CPU temperatures vary, but you really don’t want to be going over 80°C in a Multi Core test.
As you can see, my mildly tweaked (and undervolted) Ryzen 5800X just outperforms the same CPU running at its default clock settings, so I’m happy with that!
This is obviously more strenuous, but if something goes wrong during the test (like your PC crashing), then you may need to make adjustments to your CPU in the way of thermals, undervolting and so on.
Now that you’ve put your CPU through its paces, why not stress test your GPU too? Also, take a look at our GPU buying guide to see what to look for in a graphics card this year.

How To Check Cpu Temp In Windows 11?
Any component, when it reaches a high temperature, lowers its performance to prevent itself from any damage. This is called thermal throttling. Your PC components could suffer from thermal throttling when it lacks proper airflow, when it is overclocked, or if your thermal paste is dried up.
Your hardware has a high chance of degrading if it continues to operate at a high temperature, especially your CPU. However, the built-in protection does shut down the entire processor in case the CPU reaches extreme temperature.
If you want your system to last longer, we always recommend you keep tabs on all hardware temperatures. Here, in this article, we have mentioned few reliable ways to monitor your CPU temp on you windows 11 PC.
You can either check CPU temperature from BIOS or by using hardware monitoring tools.
A motherboard’s BIOS contains all the details about the system’s health. And this includes CPU and system temperatures, voltage, and fan speed.
Depending on the motherboard manufacturer, you can get into BIOS in multiple ways. In most computers, pressing the Delete key repeatedly during startup prompts you to BIOS. Refer to the motherboard or laptop user manual to get into BIOS.
Once inside BIOS, follow the steps mentioned below.
Now, search for settings named H/W monitor in your BIOS.
Although the BIOS gives you the real-time CPU temperature, it is not possible to get the temperature during maximum CPU usage. This means that when the system reaches BIOS, its temperature already lowers.
Therefore, we always recommend using a hardware monitoring application to get an accurate CPU temperature.
Hardware monitoring applications are a great way to get a real-time temperature reading. You can not only check CPU and GPU but, overall system temperature as well. Here, we have discussed a few hardware monitoring applications.
MSI Afterburner provides you with a graphical interface that provides all your CPU core’s temperatures. Like HWMonitor, it also includes CPU core usage, clock speed, and power. The application also lets the user limit GPU temperature and fan speed as well.
Note: Afterburner also works with any other devices not manufactured by MSI.
Install and run MSI Afterburner.
Core temperature not only measures the CPU temperature but also gets information about all the individual cores from your CPU. Besides this, you can also get its power consumption, power load, and frequency.
Install and run Core Temp. Under temperature reading, you can see all your core’s temperatures.
HWiNFO is a great application to not only get details about hardware temperature but also the system details. This includes information about CPU processors, motherboards, video adapters, and many more.
First, download and install HWiNFO.
HWMonitor also measures data from sensors on the motherboard and displays accurate temperature readings. Along with this, it also measures the hard drive’s read-write speed, CPU clock speed, power, GPU usage, etc.
Install and run the application.
Expand your CPU.
Here, expand Temperatures to check real-time CPU temperature.
Depending on CPU usage, its temperature will vary. On idle, your CPU’s ideal temperature should be below 35°C. But temperature under 45 °C is also considered good enough unless it exceeds this limit.
On half-load (50%), the temperature should be around 50°C to 65°C. Whereas on full load, the temperature should not exceed 80°C.
If the CPU temp is beyond these limits, you might want to perform the necessary measures to lower CPU temperature.
7 Ways On How To Increase Cpu Performance
The CPU chip, as time progresses, will not be able to perform a task as efficiently as it used to. An older chip will have difficulty processing the data due to modern software and applications demanding more computing power, or the OS taking a lot of resources.
Moreover, an overheated processor, dusty heat sink, or multiple heavy applications running in the background are also some of the reasons your CPU does not give the desired performance.
In this article, we have gathered a few techniques to increase your CPU performance. However, let us look at why your CPU is performing poorly.
One particular reason you might see a gradual performance drop is due to dust settled on the heat sink. The CPU heat sink is responsible for absorbing the heat generated from the CPU. The CPU cooler then cools down the heat sink by blowing air into its compartment.
Therefore, if you notice any performance dip, check if your heatsink has collected any dust. Besides this, here are a few reasons your CPU performance decreases.
High CPU usage
Dried Thermal Paste
Dust Settled on the heat sink
Low CPU fan RPM
Low CPU capacity
Computer with no dedicated GPU
Depending on the causes mentioned above, let us discuss how you can increase your CPU performance.
In a computer without a dedicated GPU, your CPU handles unnecessary graphic processing tasks, such as animation, thumbnail icons, and smoothing the window’s edges. Disabling these visual effects will give a slight performance boost to your system.
In terms of gaming, you will also get an FPS Boost when you adjust your PC for high performance.
If you are running an Intel chip, lowering the maximum power processor state to 99% can improve your CPU performance at a lower temperature. When you have set the maximum power processor to 100%, the processor will use all its resources, consuming more power and causing the CPU temperature to rise. And thus, the processor will start thermal throttling, decreasing its performance.
On 99%, the CPU fan will not spin at a high RPM and will not have an extreme temperature. So, the CPU will perform better with lower temperatures.
Multiple applications may run in the background right from the start when you turn on the computer. These applications will take resources, resulting in low computer performance. Therefore, it is best that you end any unnecessary background applications and disable the application that starts automatically during startup using the Task Manager.
Below are the steps to end background processes and disable the startup application.
A CPU with a dried-up thermal paste does a bad job dissipating heat to the heat sink. This results in a rise in the CPU’s temperature.
Once the CPU’s temperature reaches a certain temperature, it lowers the performance to prevent itself from any damage due to extreme heat. This is called thermal throttling. So, if you find that your CPU is not performing as it used to, try changing the thermal paste.
The dust settled on the heat sink traps heat, and the cooling fan won’t be able to cool it down. Moreover, when the CPU cooling fan’s RPM also decreases when dust gets settled on its blades.
Once dust enters the compartments of the heat sink and the fan, it does a poor job of cooling down the PC. And as discussed above, the CPU will start to thermal throttle.
Use a can of compressed air to clean your CPU heat sink and the cooling fan.
Overclocking a CPU improves its clock speed and makes it run at a higher speed than originally intended. This will result in overall improved computer performance and increased FPS in games.
When you overclock your CPU, you simultaneously increase its clock speed, and voltage supplied to it until the system becomes unstable. Let’s call this an unstable point. Once it is unstable, it turns off. And now you set the clock speed and voltage below this unstable point.
If you have a higher-end CPU paired with poor-performing hardware components such as the RAM or the GPU, you will not be able to utilize the entire CPU’s performance. This is called a bottleneck.
When your CPU suffers from a bottleneck, it cannot reach its potential due to poor-performing hardware components. Upgrading these components will make your CPU perform better if it suffers from a bottleneck.

Wondering if you’re into girls? Whether your TikTok’s “For You” page is suspiciously full of WLW content or whether you have zero idea what that means but think the girl from that coffee shop is ”really” pretty… this quiz is for you.
1 of 16
Have you ever gotten “butterflies” around a girl?Yes, for sure.
Only when this one specific girl talks to me or looks at me or shows me physical affection.
I’ve felt nervous around a girl before, but I wouldn’t call it “butterflies.”
No. Don’t think so.
Example: “Katie, I’m so sorry to have to tell you this, because it was a surprise to me, too. I have to face the fact that I am actually straight/aromantic. I think you’re so great, and there’s nothing you did wrong; this is just me having a lot of feelings for you that I’ve never had for any other girl. I’m not saying I never was in love with you, I’m saying, though, that I can’t keep it going. I care about you, but only as a friend, and I hope you won’t hate me for very long.”
Refrain from telling her stuff that will only serve to hurt her worse, like “I’m in love with Jonathan; that was the tip off.” You have to keep those emotions under your belt.
Allow her to let out her feelings. This is a huge piece of news. She is going to cry, and you’ll need to show some sympathy about that. You’re not going to make things all better, because in the end, you’re going to walk out the door and leave her. But you do owe her the consideration of allowing her to vent some of her frustration and grief to you, and treat her kindly if and when she cries. This is a huge deal to her—just wait until a guy breaks your heart, and then you’ll know how she’s feeling right now. The fact that your feelings for her were not real in no way means that her feelings for you were not real.
When you feel you’ve given her all the answers she needs, and when the conversation starts going in circles (you’re repeating the same things over and over), it’s time to go. Tell her gently: “Look, I think we’ve covered this, at least as much as we can tonight. I feel really bad about it, and I wish I could do this without hurting you, but I can’t. I have to go now. I’ll see you.” Then leave.
Don’t be swayed by pleading, waterworks, threats, etc. Just get up and leave. If you’re terribly concerned that she may do something rash, call one of her loved ones (sibling, friend, parent) and let them know what’s happened. Suggest they check up on her right away.
Give her some space afterwords. Even if you want to talk to her again, don’t initiate anything. She probably needs space to get over her feelings, and trying to chat will just make it harder for her. Keep a polite distance, only engaging in long conversations if she is the one who initiates them.
Stay single for a while. You need some time before you jump into another relationship. Reflect over your orientation (straight? asexual?) and get over the breakup yourself. Take time to focus on yourself, repair, reflect, and move on.
