4 pin fan, 3 pin motherboard, currently facing two issues
Hi
I’m just here to clarify any possible concerns instead of engaging in forum discussions. My system’s temperatures stay above 50°C, so I added a case fan—small, under 1W, low voltage. I connected the guide from the fan’s four-pin connector onto the CPU fan plug on the motherboard, and everything functioned properly. This setup should work too. I discovered a solution for this problem elsewhere.
About an hour later, suddenly the computer powered off. The motherboard’s surge protection detected a power spike. This has occurred twice more since, even when my wife’s desktop was right next to me using the same motherboard and outlet. It hasn’t happened before.
I keep cleaning my PC regularly, so dust isn’t a problem. There’s a bit of dust in the power supply, some CPU and graphics card fan dust, but overall it’s mostly clean. The power supply runs ATX Ver 2.03 with a 500W maximum output.
I unplugged the fan and haven’t seen any changes yet. After connecting two USB drives to clean and back up my system, I switched to a 480G SSD. Both USB drives worked fine before that.
Questions:
- Could the fan trigger the power surge?
- Why are my hard drives running close to the danger zone?
- Did the hard drives still overheat (around 58°C) after installing the fan, before the shutdown?
ASUSTeK P8H67-M LX (LGA1155), Intel Core i5 2500 @ 3.30GHz, Sandy Bridge 32nm, 232GB WD2500JS-22NCB1 ATA, 931GB WD10EALX-009BA0 ATA.
If you’ve read this far, you’re a strong person. Thanks.
I had it in the original message, but I wonder if it got accidentally removed. Odd.
Anyway, the shutdown happened again after disconnecting the fan, so the fan isn't the problem.
Checked the PSU and it seems that's the real issue, something that hasn't appeared before.
Changing one HD to an SSD, updating the PSU, everything should work fine.
Thanks for your time. If things don't work out, I'll reach out again.
Cheers
