Dell Optiplex GX280 fan starts spinning like crazy
-
Hi guys, I have this DELL when I turn it on, the fan starts spinning like crazy (gradually), so I have to unplug it since the noise is too loud. The OS (WinXP) never actually loads. Any ideas?

Wow. Nothing like removing the only thing keeping the CPU from melting down. Chances are you've destroyed the CPU by overheating it. Now that the CPU is probably toast, it's no surprise that Windows won't start.

As dave said the CPU may now be broken, a possible reason for the gradually louder and louder noise from the fan might be the common case of the fan being worn out. This can make it spin unbalanced (at the same, or lower PRM then normal) and therefore make loud noises. Or just that the CPU is so hot it is trying to max out the fan. (its not nice to remove the fan in that case..)

2006, 2007Intel chips from the p3 forward will not thermally self destruct due to loss of cooling. The p3 will panic shut down, the p4+ throttle themselves to stay at a safe temperature. IIRC Amd added the same functionality with either the athlonXP or A64 series chips.

Cute, but hardly foolproof. I've had to replace 3 CPU's this year, all in GX270's with crap CPU grills. They do a wonderful job of competely insulting the CPU to any and all cooling attempts. Forgot to say that the corporate "standard" is to make sure CPU stepping is turned off.

The fans in the GX270's and 280's are run by a tempurature sensor. As the CPU temp climbs, it increases the fan speed to add cooling. But, there is an upper limit to the fan speed. When it get's that high, it sounds like a shop vac. The best part about the greater speed is that it only serves to clog up the cooling grill faster than normal.
