So, once upon a time, my computer worked fine. I have a Dell Inspiron 1420, which has a good ventilation system and usually runs quite cool. A few months ago my fan broke and I had to have it replaced. The new one, however, runs all the time and is very loud.
My lm-sensors is screwed up, and scanning various threads I can't seem to find a problem like mine. So, here is what running sensors gets me: sgo542@NostalgiaforInfinity:~$ sensors acpitz-virtual-0 Adapter: Virtual device temp1: +32.5°C (crit = +87.0°C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +30.0°C (high = +85.0°C, crit = +85.0°C) Core 1: +33.0°C (high = +85.0°C, crit = +85.0°C) nouveau-pci-0100 Adapter: PCI adapter temp1: +97.0°C (high = +100.0°C, crit = +110.0°C) I've been casually browsing FireFox for a half hour and that is what it gives me. Now, I can sit this computer comfortably in my lap. That 97C temperature is clearly off, almost like it's reading in Farenheit but forgetting to convert it to Celsius. Normally it just makes my fan run all the time, but now that spring has come, it gets hotter faster. A few days ago I could only run it for 20-30 minutes before the reading hit 105C and the automatic emergency shut-down kicked in. Obviously, this needs to be fixed before sumer strikes. For reference, this is what I get from sensors-detect: sgo542@NostalgiaforInfinity:~$ sudo sensors-detect # sensors-detect revision 5946 (2011-03-23 11:54:44 +0100) # System: Dell Inc.

I am moderately experiences with Linux, but by no means an expert. Any help would be appreciated, before it gets hot outside and my computer becomes completely unusable. |
