Throughout POST (Energy-On Self Take a look at) check, your motherboard makes certain that each one main {hardware} parts are linked and in a working state. This consists of the CPU fan as nicely.
CPU fan is what cools down the CPU chip when its temperature rises. The warmth is transferred to the warmth sink. CPU followers then cool the warmth sink. And that is principally how a CPU cooler works.
If you don’t place the CPU fan header to the right pins on the motherboard, the fan might not spin in any respect or will spin at a decrease RPM. If that occurs, there may be nothing to chill down the warmth sink. That is whenever you face thermal throttling. That means that the CPU will lose its efficiency.
Right now, to keep away from this actual difficulty, we’re right here to offer you an in depth and easy information to connecting the CPU followers header to the motherboard.
Does It Matter The place I Plug My CPU Fan?
If nothing is linked to the CPU_FAN header on the motherboard, it should show some errors through the POST check. If the pc passes the POST check, the CPU fan may spin so long as it’s linked to the SYS_FAN header. Nevertheless, it should spin at its most RPM, making lots of noise.
In addition to this, the voltage equipped to the CPU_FAN header on the motherboard is temperature-controlled. That means that relying on the temperature, the system will increase or decreases the temperature. You’ll not have this function should you join the CPU fan to a distinct header.
Learn how to Join CPU Followers Header to the Motherboard?
Inserting the CPU fan connector into the motherboard is a straightforward process if you already know the place the headers are positioned on the motherboard. You want to join the cable from the CPU fan to the header named CPU_FAN in your motherboard.
First, allow us to see the place this particular header is positioned.
Find CPU_FAN Header On Motherboard
As you’ve got already seen, the wire from the CPU fan is comparatively quick. Due to this fact, the CPU_FAN header can also be positioned close to the CPU socket on the motherboard.
To find them, seek for the four-pin header in your motherboard. You may see a number of four-pin headers. Guarantee that CPU_FAN or CPU_OPT is written beneath it. There could also be a single or a number of CPU_FAN in your motherboard.
If it has a number of CPU_FAN headers, it’s indicated as CPU_FAN1, CPU_FAN2, and so forth. Just remember to don’t connect with the header named SYS_FAN.
Insert the Cable From the CPU Fan
When you find the CPU_FAN header, take the wire from the CPU fan. Align the cable and the header and gently join. This cable solely goes in a method. So, don’t pressure them in should you can’t insert them. Flip the cable and check out once more.
After connecting the CPU fan to the motherboard, activate the pc to verify if the followers spin. When you’ve got the motherboard linked to the monitor, verify should you see any errors concerning the CPU fan through the POST check.

Is My CPU Fan Appropriate With Any Motherboard?
CPU followers usually have a four-pin connector, and most motherboards additionally include a four-pin header. So most CPU followers are suitable with any motherboard. Nevertheless, the case just isn’t the identical for the CPU case fan.
CPU case followers both have Molex, three-pin, or four-pin PWM connectors. Due to this fact, your motherboard should have the fan’s respective header for connection. You may must get a converter if it doesn’t have the required headers.
Learn how to Join System Fan on the Motherboard?
Relying on the kind of fan, you possibly can both join the CPU case fan or the system fan on to the motherboard or the facility provide.
When you’ve got a 3-pin or a 4-pin cable from the case fan, you possibly can instantly join them to the motherboard. Nevertheless, if the case fan has a Molex connector, it’s essential join it to one of many cables from the facility provide.
The three-pin and the 4-pin cable go within the header named SYS_FAN in your motherboard. Though SYS_FAN has a complete of 4 pins, you possibly can join it to a 3-pin connector as nicely.
Learn how to Management CPU Fan Velocity?
You may both use the BIOS or some third-party software to manage your CPU fan velocity. BIOS gives handy methods to manage CPU fan velocity, however having a third-party software makes it lots simpler to manage CPU followers and system followers.
If you wish to management the CPU fan utilizing the BIOS, comply with the steps talked about under.
- Press the BIOS key repeatedly throughout startup to enter your motherboard’s BIOS. The BIOS key on your system can both be one of many operate keys or the Delete key.
- Now, seek for settings like Cooling, {Hardware}, or {Hardware} Monitor.
- Relying on the motherboard, you possibly can both absolutely management the fan velocity or set a sure fan management mode.
- As soon as you alter these settings, Save and Exit the BIOS.
Why Is My CPU Fan Not Spinning?
The very first thing you need to verify when the CPU fan doesn’t spin is the wire from the CPU fan. Just remember to verify the cable from the CPU fan is linked to CPU_FAN header on the motherboard.
Secondly, the PSU additionally wants to provide sufficient energy to all the system. When you’ve got a CPU fan that isn’t spinning, strive utilizing a distinct PSU with the next voltage.
Why Is My CPU Fan So Loud?
CPU followers usually spin at the next RPM when the CPU reaches a excessive temperature. Due to this fact, checking the CPU utilization must be your first precedence when you’ve got a CPU fan that’s noisy.
In addition to this, right here are some things you possibly can attempt to decrease CPU fan utilization.
- Finish background processes
- Clear CPU warmth sink
- Poor case airflow
- Be sure the cable from the CPU fan is linked to CPU_FAN header on the motherboard
