The exhaust case fan in my 13-year-old pc finally started packing in so I purchased a 120mm Silent Wings 3 PWM fan, to eventually keep as a spare with a new build. The motherboard is an Asus P6 Deluxe with only 3 pin chassis connections and Q-fan control for DC fans. I read that connecting a 4 pin plug to the 3 pin header is okay, merely leaving off the pin that delivers the PWM voltage. I have enabled Q-fan to that fan set to standard and it appears to be acting as a DC fan, HWinfo64 telling me it is spinning at around 1200rpm, slightly ramping up on pc use. Am I right in what I have assumed? Incidentally, HWinfo64 also tells me my CPU fan is either at 0 or around 84000rpm!

Does your motherboard have any BIOS updates pending? That CPU Fan reading doesn't seem right. You could also use Asus's Probe II (roman for 2) app to see what it shows you in terms of CPU fan RPM.

Not bothered about that erroneous CPU fan reading. Looking inside the case it is spinning nicely, not melting, and the CPU temperature is low.
