Does it matter where I plug my CPU fan?

post #1 of 10
Thread Starter 
When assembling this rig, late at night, I accidentally plugged the CPU fan into a sysfan port instead of a cpufan. Does it really matter or should I tear up the whole thing just to switch ports?

If you plug it into the CPUFAN port your motherboard will be able to throttle the fan speed based on temperatures, otherwise it will just run 100%, not necessarily a bad thing if you can handle the noise.

I would plug it into the cpu fan port as that is temperature controlled. but i mean the other ports would run it at full speed so either or is fine. and it should only take 2 seconds to move the fan around.....less u got a massive cord mess inside.

Yes and No. No because it will operate off of any header, and yes becuase most motherboards will give an error during post if it doesn't detect a fan in the CPU fan header.

It's a Zalman fan, there's no noise and yeah, there's a massive wire mess inside, and I mean massive, but I don't really feel like cleaning it during the weekend.

This.


but if you have another fan plugged in to the CPU fan header it wont give you the error.


or you can go into the bios and tell it not to halt for any errors.

Yeah, I switched it to CPUFAN1 now, Control Center is no longer going crazy with sirens and all that stuff.
