Hey, so I just built a new rig, specs are:
i5 2500K @ stock 3.7 (Runs at 1.6 when idle)
CM Hyper 212 Evo
4 x G Skill 4GB 1600MHz 9-9-9-24-2N
MSI 560GTX Ti
Windows 7 64bit
At idle my Cores are running at about 27-30 C and in hour long Prime95 tests it runs around 50-55 C (measured by SpeedFan and RealTemp).
Now what is really confusing is that when idle, SpeedFan and CPUID Hardware Monitor show my "CPU" (Case temp I guess) as 85-90 C but under 40 C when in a Prime95 test.
This is consistent behaviour, I've done a few PC restarts and starting/stopping of the Prime95 test and the outcome is always the same. And the temperature changes from the idle to load ranges and vice versa within about 5 seconds after starting/stopping the tests.
Is that the programs not reading the sensors correctly, something is wrong with the sensor itself or is it possible that it is actually happening??
Thanks in advance.
EDIT: Also, if it is a case of just an incorrect reading, do those temps sound about right for this i5 at these speeds with a Hyper 212 Evo (using the fan and paste that came with it)? Or have I likely botched applying the Paste? (It's my first time)
While in the BIOS, CPU = about 30 C, CPU Fan = about 1000 rpm.
In Windows I use Hardware Monitor and I get the following (all temps from the Mobo except Cores);
Idle: CPU = 82 C, CPU fan = 950 rpm, Core Avg = 32 C (also AUX = 58 C, TMP = 32 C)
Prime95: CPU = 37 C, CPU fan = 1375-1400 rpm, Core Avg = 50 C (also AUX = 50 C, TMP = 51 C)
SYS always sits at about 26 C.
EDIT: Oh and the CPU temp changes between 82 and 37 instantly after Prime95 is started/stopped. AUX, TMP, Cores, CPU Fan Speed all take a few seconds.
