Got an i3 530 rig up and running on a H55M-UD2H board, updated to latest Bios, and a zalman 9300 fan (great offer OCUK BTW). I started to do some testing on stock at the moment so i can see how much difference in temps etc when i start to overclock. Tried the latest version of coretemp, speed fan and they all give me some daft results, in speed temp it gives my core temps as -8 and -11C, and coretemp seems to only show the delta from the max to be 98 and 85 or something? The only programs that seem to work is CPUID HW monitor and the gigabyte one that comes with the PC. On idle in HWM core 0 is at 10c and core 1 is at 16c this seems to be a large difference between the 2 cores. I ran Prime for an hour or so and temps got to 18 and 24c respectively, all on stock freq/Vcore, does this seem to be correct? Just a bit worried that if i start to OC i wont have a reliable way to check the temps, also would it be worth to re-seat the Fan to try and equalise the core temps?
