fan on NB=unstable. no fan=stable?!?!

post #1 of 24
Thread Starter 
Ok after doing some testing with my comp outside the case, I did not have much on it

after loading it back in the case, it would not stay steady - constantly locking up. after removing stuff, I have brought my issue down to 1 thing. Antec Spot cool fan.

I remove the fan and I can load into windows and start running OCCT. I put the fan back in, and I can get into windows still. I strap the fan to my NB heatsink.... and I cant even get to the log in screen

Why is this happening? how do i fix it?

how the hell do i keep a fan on my nb?

1) Make sure the fan is, in fact, spinning while it's plugged in
2) Try a BIOS update?

Well if it runs stable without the fan, why not just not use thefan? Seems logical.

that's insanely hot.

The fan uses a 3 pin and plugs into the motherboard?

Just use a converter and use a regular 4 pin molex for it.

If it still doesn't work then the fan is touching something it's not supposed to and shorting something out causing instability.

maybe the motor is putting off enough electrical noise to play some havok there?

I had the fan dangling by a wire because at first I thought the motherboard mount was shorting out a capacitor it was near. removed the mount - still


Ill try finding a molex converter but I am using most of them, Ill try to swap em out and maybe throw that fan on the controller.
