Can someone help please? I've just finished building my 1st PC but think I may have a problem with one of my case fans. The case I've used is the Thermaltalke Tsunami Dream with the Asus P5N32SLI - Deluxe Mobo. In both the BIOS & the ProbeII program (from the mobo support disk) Chasis Fan 1 is showing up as a warning running at 500rpm - should it be running any faster? If so any ideas on ho to get it to do so?
