I have 4 variable speed fans in my case; when I run 3D applications or run any other demanding programs, naturally, my computer will heat up. Therefore causing the fans to go ape-sh*t, constantly changing speeds. I phoned my system manufacturer and they said my motherboard was controlling the speed of the fans; I checked in my bios and couldn't find any options to do with then fan's RPMs. Then I updated my bios with a "bootable BIOS Flash diskette" that I downloaded from my system manufacturer. But there are still no options to do with my fans. After all of this I started looking for software to control my fans and so far have been unsuccessful. Does anyone know of anything that I could do, or any software that I could buy/download to solve this problem? It's really driving me crazy!
