Laptop cpu cooling fan
Hi! Not posted in a while but i need your help desperately. I got given a laptop. The model is an Fujitsu Siemens Amilo K7600. The cpu fan doesnt spin - apart from that the laptop is perfect.
Therefore it overheats - but i definately know that the cpu hasnt fried yet as it still live cd boots linux when i boot on a cold morning lol. So, i located a similar fan, which the guy said worked (i dont know if it ever did but i ***ume it does) and it wont spin either. So i think there could be an underlying problem, why might power not be getting to the small 3 pin fan connector. This is most odd, I am at a loss of what to do next, any ideas? |

MOST pc's will not work if no cpu fan present: which is good news. Your fan header may be bad, BUT pc apparently will work regardless. Plug the fan into another header. TEST both fans-the new one could be defective. Try drop or two of graphite bearing lube. Make sure there is nothing physically preventing rotation (deforming from overtightening screws, wire, etc). Use an appropriate-range multimeter to test the header.
I'm, not sure what voltage most laptop cpu fans are, but seems to me you can find another power source if the header is burned. It is feasible the fan bearings dried up, drew too much power and overloaded the circuit. Just a couple guesses...good luck |
