I have a Compaq Presario R4000 running Ubuntu Linux 9.10 karmic. The system runs very hot and one of the fans is wither never running or always running at the slowest speed. For a while I thought the fan was dead but I just updated the BIOS (Phoenix BIOS) and during the update, that fan suddenly kicked in at full speed!
How can I get that fan to spin up during normal usage? I have tried sensors-detect
but all it found was k8temp
, no fans...
(SpeedFan under windows found no fans either)
Well when running BOINC, the temperature rose to 144°C with no fan activity. So if it's controlled by hardware then the hardware isn't working. If doing a BIOS update made the fan run at full speed shouldn't there be some other software based way of getting the same effect? – Josh – 2010-04-26T13:59:44.933
2CELSIUS? 144C is alarmingly close to the melting point of solder. If you're absolutely sure it was C and not F, your laptop is in serious need of repair -- something is very, very wrong. Your CPU should have shut down well before it hit 100C. The BIOS updater probably poked some very low-level thing to get the fans spinning, as it was already in a position to do so. This was likely a significantly lower-level operation than can be easily exposed in modern operating systems, so for all intents and purposes, it's not software controllable. – Jessie – 2010-04-27T08:27:33.663
Well I have the temperature monitors in Fahrenheit, and two of them were reading 288°F I believe. The third one was far lower, but I forgot now what exactly it was. 110°F maybe? Something is clearly wrong and I suspect I need to be looking for a new machine. – Josh – 2010-04-27T17:57:47.343
