Something strange has happened with speedfan or my motherboard.
I was testing the fan that came with the Hyper 212 Evo via speedfan, I had logged fan speed percentages in 5% increments and the fan speeds in rpm, I swapped over to the AC F12 and speedfan no-longer showed a fan speed. I tried all 12 combinations of setting in the advanced tab and got nothing. When I then swapped back to the included fan I had the same issue, I the tried both fans on "Case Fan 1" and checked all setting in speedfan and even tried changing the setting in the BIOS.
I cant believe that unplugging a 4-pin PWM fan and plugging in a 3-pin fan has broken something. This is pretty strange.
I have restored my system via Aronis True Image to reset Speedfan to a working state when I still had the puny Intel original fan being controlled via speedfan. Now however there is no fan control at all via SpeedFan
I have restored my system to a point before I meddled with either the BIOS or SpeedFan.
I Installed the latest version of SpeedFan.
I have reset the BIOS to factory defaults.
I have updated the BIOS to the latest version (1.7 vs 1.5).
I have installed MSI specific software for my motherboard to control control the BIOS from within Windows (this is weird IMO).
I have installed MSI specific software for my motherboard to control control the Fan Speed above and beyond the BIOS via software within windows, in a similar (and far easier to use) way than SpeedFan.
However nothing (BIOS included) shows FAN RPM's (or seems to work correctly in SpeedFan). Apart from this being peculiar, this is a real pain in the arse as I controlled my previous CPU fan via SpeedFan (beyond) perfectly well, and everything was going OK with this until I switched fan (for SPCR reporting reasons and questions).
Should I return the motherboard (total pain in the arse), or should I try other things first....?
FYI... I have the CPU fan plugged into "SYS Fan1" currently as I have been too lazy to re-plug it back into the CPU header. Between the "Auto" control in the BIOS and "MSI ControlCentre" (if it does anything when not running) the CPU core temps don't top ~73c and the PC has not crahed whilst playing Far cry 3 @4.2GHz (default everything else except the RAM which is rated for 2.0GHz under an XPM profile).
Please share your thoughts.
