i have a coolermaster elite 431 plus.it has 3 fans total top fan n rear is exhaust and front is intake but no temp diffrnce during bf3 is same 76 cpu previous u had simple cabby iball no fan in that temp was 76 so y no diffrnce
I would try reapplying thermal paste, check all fans are operational, then check if there is nothing blocking airflow, like a toolbox or just a box of old floppies, gotta look for the small things, otherwise, most Temp checking programs go by what the BIOS Says, re flash your BIOS.
