CPU fan headers dead, alternative connection for AIO

Craterloads · 29 Apr 2021 at 22:08

Hi, my cpu fan headers on my motherboard are fried (3 of them 2 cpu & one pump header)

what’s the best option for connecting a normal cpu cooler (single fan header) or a AIO cooler which I guess will have a pump header too.

can I just connect to the normal motherboard fan headers without issue?

The bigger question is what are you doing to burn out fan headers?

You can use a 3 pin header but you wont be Able to control the fan speed linked to cpu temps, as @Minstadave mentioned why are they burning out.

Most BIOS will let you regulate fan speed via the 3 pin headers still (just using DC control rather than PWM).

Yes thats true but can you link it to cpu temps thought you needed the cpu header for that ?

All of my fan headers have the option of linking to the CPU or system which I'm guessing is the VRM.

Bought board at a Carboot sale for £2

so was like that when I bought it, there’s a couple of burnt out caps near the headers so probably previous owner plugged something not suitable.

X570 hero, high end board which was worth a punt at £2

otherwise all working

cheers I’ll see if there is anything in bios
