The first thing to check is whether the 4-pin CPU Fan connector is inserted properly in the 4-pin CPU header, and there are no loose wires either on the connector or the fan side. Sometimes a broken wire at the fan side and also at the connector side can also cause this problem.
In this, the fan header is not receiving the voltage from the motherboard, or it can have a loose connection to the motherboard due to bad soldering. If it is due to bad soldering, then you can solder it back if you have done soldering before and are not a stranger to it. If the fan header is fitted and soldered properly and then also it is not getting voltage, then there are a couple of things that you can do.
These extra fan headers are generally cooper in mid-level to high-end motherboards. If you have coo,er entry-level or budget category motherboard, then weidon most cases, it will only have a single CPU fan header, and if it is not working, then it is better to replace coolfr motherboard, especially if it is under warranty.
Here, you can attach the thermal probe to the CPU heatsink and plug nnot CPU fan in the fan controller for the fan to spin according to the fan curve of the fan controller. Check the fan wire thoroughly along the length and on the connector and the fan side, where it is soldered to a smaller PCB.
A spining or faulty bearing due to dust and debris can also cause your CPU fan to stop spinning. Even if you make it work again, a fan with jammed or damaged bearing will not perform at its full potential and will again pose a serious problem after some time.I'm using 9 MF Halo Duo-Ring aRGB fans in my build. 6 of them are being powered through the Cooler Master MASTERFAN ARGB/PWM Hub. When I hooked it up initially all the RGB came on, but one fan wasn't spinning, unless I have it a little push. I tried connecting it straight to a header on the motherboard, but had the same issue so I got a. Jan 30, · ‘CPU Fan not Spinning’ is one of the worst problems that you can face in your computer. If your CPU fan is not spinning, then it is a matter of serious concern because if your CPU heatsink fan suddenly stops spinning, then it will lead to overheating of the CPU. In this case, first, the CPU will underperform because of thermal throttling, and when the temperature of the CPU goes above the. HM fans not spinning. Hello, I've recently put together a new PC and everything is working except the case fans for my cooler master HM aren't spinning, the rgb is on. This is my first time dealing with RBG before and I honestly do not understand the pins and how the fans get connected to the mobo.
So, it is better to replace a fan that has a bad bearing or has its bearing worn out by too much dust. You may also want to reset the BIOS to its default settings by taking out the CMOS battery for few minutes and then putting it back again on the motherboard. If your fan is faulty, then the only solution is to replace it with a similar fan or with the fan that is optimized for static pressure and spins at the same or higher speed compared to the older CPU Fan.
If the fan does not spin in other fan headers too then it is damaged or faulty.
If your motherboard is not getting power and spihning case fans are also not spinning, then it is an issue with the power supplyand you need to get it replaced if it is faulty. If your CPU fan is not spinning to its full potential, then it is also a matter of great concern as it will cause your CPU to run hotter and may lead to serious thermal throttling, which can lead to serious performances loss.
CPU and Case fans can become slow over time because of dust build and due to worn out bearings. Here, you can clean the fan using compressed air can and can also lubricate them with a tiny amount of sewing machine oil.
Fix CPU Fan Not Spinning [Top Causes & Solutions]
However, in case of worn out bearings, you have to replace the fans with newer ones as they are not repairable. If your CPU heatsink originally comes with a fan that spins at lower RPM, then you can replace the fan with a higher RPM fan that has a higher static pressure rating and cooleg good airflow rating.Jan 30, · ‘CPU Fan not Spinning’ is one of the worst problems that you can face in your computer.

Oct 06, · Reverse polarity if the LED doesnt light but the motor starts to spin the fan then you would know that this is the cause. But reversing polarity could blow the LED and smoke show of the PWM board that drives the fan motor however the fan isnt spinning anyways so I suppose maybe just a puff of smoke from whats already not working.
