Just finished a new build (see sig) and after reading the posts on fan control I started doing my burn-in tests. The excellent posts on fan thresholds worked like a charm, preventing any stalling. The raw commands used to set fan profiles/per-zone duty cycles also seem to work.
The issues is, that my 2 Noctua NF-A14 iPPC 3000PWM fans won't get above 1500/1600 RPM, even after setting the fan profile to full and running prime95.
Noctua fans are connected to the FAN4/FANA headers on the mobo. I plan to buy another 3x120mm noctua fans to replace the case fans of which only 2 are connected right now (they're 3-pin fans).
I'm using a linux livecd's for testing, together with ipmitool. The rpm's are confirmed by the ipmi sensor readings in the web interface.
Set fan mode to full and check again.
Start prime in another window, wait for temps to rise and check again.
Am I doing something wrong, or are both fans damaged? Another theory I have is that the _reported_ speed is halved, thus explaining both my low rpm at idle and load (wishful thinking).
