With the Hardware Monitor within the BIOS displaying 0 RPM, I believe there is a hardware issue.
That's basically what I was thinking also.... could the fans be faulty? These are available from the Asus EU site for ~30€.
If the fan doesn't give RPM feedback, could that explain why they are ramped up so much?
Or is it more likely that the entire circuitry controlling fan voltage is wacked?
The fans do spin down after a while and can be very silent in between...
What kind of CPU temperature do you guys have when idling in the BIOS? Any Fan activity/RPM there?
And do your systems show you the RPM both in the BIOS and in the Gaming Center?
*Edit*
I just started it up and have the BIOS screen up. It started with a CPU temp of 27 degrees, no fan active. It slowly climbed and once it reached ~45 degrees, the fans started up - fairly slow first. Temp started dropping, went below 40 again and continued to decrease. But instead of lowering fan RPM, it continued slowly ramping up the fans even when temp was around 36-37 degrees. It dropped down to ~35 and then became somewhat quieter again, but temp rose slightly to 37 after. It continued to lower fan RPM until it became quiet again, but temp of course rose again and the cycle repeats itself it seems.
Still, this seems somewhat normal. Yesterday it was sitting in the BIOS with fans ramped full speed for 10-15 minutes until I grew tired and switched it off. Temp was as on the pictures above, 37 degrees or so. At that time I restarted into BIOS from Windows with fans running high speed though. This time I started off directly into BIOS and with cold CPU. Also I'm currently running on battery only...
What I would really like to know is how the logics work here - once CPU temperature exceeds a set treshold it seems to start up the fans to get temps down - then once temps are down fans are throttled down completely, and the same thing repeats itself. Why does it not run at some "steady state" low RPM value and keep the temp around 40 or such?
Can I define a fan profile anywhere in one of the software packages?Do your systems behave like my description above? Around which temperature does the CPU hover in BIOS/idle? I seem to be between 35 and 45, depending on what the fans do. Is that normal?
*Edit 2*
I've now sat watching several cycles and it seems to be consistent; fans spin up around 45 degrees and pull temp down to around 35, where fans go completely silent. This repeats itself over and over. Actually seems ok, but not the type of fan profile I would prefer.... Perhaps it IS a fan problem and they are not responding to low voltages? I.e. the system is trying to run them at low RPM but instead they're completely off?
No doubt that CPU temp climbs without any air flow...
