hey, i've bought the new Zalman CNPS9900 becuz it was very quiet and had somthing called silent mode.
but its like mine are running on full load all the time
i got an athlon 7750 2.7ghz dual core, it runs at 21'c idle and i dont understand, do i need any driver or somthing ?
I have this cooler and can confirm it shouldn't sound like it yours does! There is an option in BIOS to always have the CPU fan running at full pelt, can't remember what it's called though, but check in your BIOS for something that looks similar. It sounds like you have that setting set to on, turn it off and hopefully Bob's your uncle.
If you can't find it, I will have a look in my BIOS and see what it's called, but you shouldn't have much bother (unless you aren't familiar with BIOS tweaks)
