constant fan speed w/o root priv.

My system admin just replaced my old 2GHz machine with a new 3 GHz machine, which I should be profoundly thankful for, i guess.

However, when I'm running the CPU at 100% (which I do pretty much contantly, since I'm doing calculations on the machine), the case fan goes through a cycle of ~40 second low speed, and then ~20 second high speed. at high speed it is VERY loud - enough to cut through my headphones with music on them. It's driving me nuts.

So my question is: since the fan is apparently not running for 2/3'rds of the time, could I make it run at a constant speed, somewhat higher than the low?

I should mention that I don't have root access, and our sysad refuses to do any individual customizations....

I think this depends on how the hardware is constructed.
I don't think that the OS controls the cassis fan. I may be wrong, but I think it i controlled more directly by a temperature sensor on or close to the fan.

Input any of you hardware gurus?
