I have an i7 920, zalman cnps9900 heatsink and fan, arctic silver thermal paste and gigabyte mb with no overclocking at the moment. I have three internal fans one push and 2 pull. but my cpu has recently started to run hotter. I have sounds enabled in bios above 70C. Checked using core temp and speedfan it looks even worse. These are at idle! Core temp says i am running around 52c and speedfan a touch higher. Vcore1 1.23v, vcore2 1.41V, 2670 mhz, vbat 3.26V full fan power (Can't post images without 10 rep).
I have cleaned it thoroughly including the heat sink where I did alcohol wipe off existing paste and reapplied a thermal as per guidelines but still no joy.
Anyone got any ideas. Could it be my cpu/mb is slowly dying?
PS I do have reasonable ventilation and tend to leave the computers I have on or in sleep.
