NB Fan broken? Creepy things happened
My computer turned itself off. After several attempts at turning it back on (it just turned back off), I got it on and went in the BIOS. CPU temperature was 98 CELSIUS and system temp was 58 C. CPU fan was fine, and CPU temp went down to 68 in less than a minute, but NB fan was not on. I opened it up and discovered CPU fan was partially unplugged from power, so I plugged it back in. NB fan had a lot of friction, must have been what made it stop.
But why did my CPU get the heat? Did both fans coincidentally stop working at once? Anyway, I have other problems now. I took off the NB fan and found it was cracked and looked burned. But I can't get the heatsink off. It's on some kind of plastic cylinders which I think contain springs. I can pull it off the mobo, but nothing else. Paste this image URL in your browser to see: img465.imageshack.us/img465/1353/nbzm1.png How do I detach this thing, and how do I know which NB fans/heatsinks are compatible with my mobo? System: MSI P4N Diamond (MS-7160) <--this is an nforce SLI Intel edition Pentium 4 3.2 GHz 2GB Corsair RAM 2xGeForce 7800 GTX OC On-board SBlaster Live! Nothing is overclocked. Was, but I turned it back to normal recently. Last edited by angie; 17-03-2007 at 09:21 PM. |

Thank you! Perfect answers, to be implemented immediately. BTW, my computer runs fine without the NB fan (I got impatient). I think recent unexplained system instability is probably due to the broken fan.
