what does coolerxp do

this little prog came with pcalert.
i find pcalert annoying for purely aesthetic reasons, it's to big.
i run mbm & cooler xp.
so... when i run cooler xp it drops my system from what ever temp it's at to about 8-10 degrees over ambient.
how?
all i have is a regular "recommended" amd certified HSF.
going water cool when i got the cash.

It underclocks or put the computer into sleep mode, you only beneift from the temperature drop while your computer is idle. Most people don't use programs like that because of the range of temps the CPU is put under, the spikes...
