Core i5 2500k CPU temps

[RMontemayor]

Howdy everyone. I just built my first self build this weekend. Everything seems to be running fine, but am a bit concerned about the CPU temps I am getting. They do not seem to be that high or alarming but a bit higher than what I expected. Nothing is overclocked, except for activating XMP in BIOS for the RAM.

Equipment:
Intel Core i5 2500k
Asus P8Z68 V Pro mobo
2 X 4 (8GB) Corsair Vengeance RAM 1600
Coolermaster Hyper 212+ CPU heatsink with one fan
Corsair 600T white case front 200mm fan, top 200mm fan, 120mm fan rear
Win7Pro
Ambient Room temperature about 25 C +/- a few degrees

In the BIOS at startup it reports around 44-45 C in either EZ mode or Advanced. In the AI software it reports around 36-38 at Idle. CoreTemp reports:
Core 0 - 29 C
Core 1 - 37 C
Core 2 - 29 C
Core 3 - 34 C

Running Prime95 torture test blend on all cores I get:
Core 0 - 50 C
Core 1 - 58 C
Core 2 - 54 C
Core 3 - 57 C

I admit I am a newbie. Are these temps ok? Is it normal to see a spread of 8-9 degrees between cores (Cores 0 and 2, and Cores 1 and 3 seem to track together)? Is it normal for a large gap from the BIOS to the software readings(AI suite and CoreTemp)? Possible motherboard issue that needs to be replaced or good enough? Take off CPU heatsink and remount needed?

I just want to confirm everything is running smoothly before I do any mild overclocks. Thanks.

Those temps are just fine. It's perfectly normal to see several degrees difference between the cores.

If you REALLY want to stress your system for temps...try the Intel Burn Test.

I recommend starting with standard and working your way to maximum.
