Compaq D300 Overheating
Posted on 2006-06-14
Need help with an intruiging problem:
Called to a client site which has a Compaq D300 which is overheating;
When the machine was powered on Not one of the 3 fans were working; ie Power supply fan, Chassis fan, and CPU Fan; (client had installed an additional low powered extractor fan in one of the chassis expansion slots but this was not strong enough)
Then the Basic problem was that after a period of time the chassis internals (CPU) got hot and a message came up on the screen and performance degraded
I thought I had some type of PSU issue or maybe a motherboard config problem or maybe a BIOS issue.
Checked the BIOS: Could Not see anthing amiss
Checked the power supply and concluded that given that all peripherals were powered and Motherboard was powered that most likely there was not an issue here;
The fact that all three fans were not working did seem too coincidental and lo and behold in the middle of all this investigated and observation the fans kicked in and started up;
Now that leads me to a conclusion that there may be some faulty thermo control on the motherboard that randomly kicks in;
Could the root of this be a faulty motherboard and if so how can I determine what the fault is.
