I just replaced my fan in my nc2400. It was a 5hour job. Had to pull EVERYTHING to get to where they have the fan in the thing. Now I want to know if it is working. It is suppose to be thermostatically controlled, and it takes time to heat up. So how can I find out what Centos knows about the system temp and fan state? It was hard to tell if I put the connector in the right way. At least if that is all I did wrong, I can get to that connector with only pulling the drive....

I thought the Exhaust Fan for the CPU was dead (and the motherboard damaged). He told me that when that fan runs, it rotates very slowly (unlike the fan in the PSU) and that it probably doesn't run very often. Each time he touched the Shroud over the CPU, it was very cool. I read something in a forum, that said the CPU temperature can go to 100 C., in a few seconds, but I now wonder if that is true or not. Hopefully, as the previous reply indicated, lm_sensors can tell you what's going on. My box has a new ATX PSU and I'm *very* thankful Dell did not install a proprietary PSU and mobo in this model!

I answered yes to every prompt and nothing was found for my system. So now I guess I read man pages and google a bit....

Getting louder all the time (shot bearings or bushing or whatever it has). So I know that my old was turned. And the unit ran hot. Now with the new fan in, it is not turning at all, but the unit is actually cooler than before, but still hot to touch. Could be better contact with the heatsink. Either I put the power connector on backwards (the manual's pic is not clear on this, but I don't know if that connector CAN be put on backwards), or there is something with the bios with this new fan...

The BIOS usually can also tell you the temperature. Kai -- Kai Sch?tzl, Berlin, Germany Get your web at Conactive Internet Services: http://www.conactive.com

Then I went into the BIOS and set it for the fan to always run while on AC. Then reboot. I will say that when the old fan was failing, there were times when I took the unit out of hibernate and the fan never came on and the unit began to overheat. Turning off, or even just going into hiberhate again, then restarting tended to get the fan working again. Some state lost thing. I had the unit in hibernate when I tore it apart to install the new fan... So now there is the bearly heard whisper of the new fan turning. I can actually hear myself mutter, and I don't end the day with a headache!

Since your on AC, you are not worried about battery performance, so keep the fan going and don't be so fancy with managing temperature....
