The Corsair case fan is having trouble spinning.
The Corsair case fan is having trouble spinning.
Hello everyone, this is my initial PC build and the case I’m using is a Corsair Carbide Series 175R RGB. The only front fan that came with the case is extremely loud and keeps struggling to spin whenever I powered down the PC overnight. This is quite unusual.
I observed this issue when I removed the case fan and connected both the Noctua front fan and the system fan (case fan) using a Y connector cable to improve cooling. I double-checked everything was properly plugged in and there were no obstructions, yet the problem persisted.
Additionally, whenever this happens, the PC takes longer to boot. I’ve attached some videos about the problem for reference.
My current specifications are:
Power Supply: Cooler Master MasterWatt 750W 80 Plus Bronze,
Cooler: MOBO GIGABYTE B550M DS3H,
GPU: Aorus Elite 3060 Ti,
Processor: Ryzen 5600 X
Any assistance would be greatly appreciated!
Super Loud Fan Not Spinning
Slow Boot
A fan won't start without receiving 5v, possibly around 500 rpm. The splitter could be responsible for the problem.
More likely, the fan settings in the BIOS initiate the fan at a low speed, lowering the voltage to it if it's a 3-pin model.
The BIOS checks for a CPU cooler during boot by verifying if the CPU fan is rotating. This might be contributing to the delay.
It's recommended to connect only the CPU cooler fan to the CPU fan header.
Attach the loud front fan to another motherboard header and modify that fan profile to balance cooling and noise.

Thank you for your patience. I changed the case fan to connect directly to the 4-pin connector on the motherboard, using an extension because the case fan is a 3-pin. I hope this resolves the problem as you suggested. I plan to test it tomorrow to see if it works, since I believe the issue only occurs when the PSU's switch remains off for an extended period, typically overnight.
I didn't realize you could link it directly even with a 4-pin header. This morning the fan operated smoothly without any loud sounds, so I think the splitter was the issue. Could you confirm if the problem was that the splitter prevented the case fan from getting enough voltage? I'm not sure how to prevent this when you don't have enough headers for all your fans.
I understand, if it happens again I'll adjust the BIOS settings for the case fan speed and see if that helps. Thanks for sharing, you really gained a lot! 😊
