Detecting CPU throttling on over temperature

Hi, I recently discovered a system where the floppy drive cable was intermittently fouling the CPU fan - I believe this caused the CPU to overheat and then get throttled by the BIOS. Does anyone know if it is possible to determine if this is the case? ie is there a way to be informed if

I don't know whether there is a more convenient way, but you could definitely check the current CPU frequency to detect whether it changed from the previous one or not. There are several ways to this, depends on the CPU. You can try messing with cpufreq(4). On Tue, Sep 8, 2009 at 2:39 PM, Daniel
