Hot 1&2 cores

[Stanfiem]

Hello everyone I am new to the forum and would like to say welcome. I just built a PC a couple of days ago and am putting it through some warm up and checking to make sure everything is stable before I start pushing it. I have a couple of questions for you all.

First this is what I am working with.
i5 2500k stock (right now)
MSI twin frozr III PE/OC 2gb 6950
Gigabyte GA-z68xp-UD4
CM Hyper 212+ (Tuniq Tx-4 TIM)
Rosewill ranger (2 intake, 4,exhaust fans) Case
72000rpm HDD
2x4gb(8GB) DDR3 1866 9Latency 1.5v (stock)

I am getting some interesting heat on the 4 cores. they read like this (realtemp) Idle:0-27 1=30 2=34 3=25 Load 100% using prime 95 (blend): 0=40 1=46 2=50 3=42 The 1 and 2 cores are always hotter than the 0, 3 cores but temps have only maxed out at 53 degrees (67 F ambient). I was wondering if this was indicative of an improper heat sink placement and I needed to remount. I twisted the screws in an even cross patter so I think I mounted it correctly however this is the first time I have ever mounted a heat sink. Thanks

I was wondering if you guys knew of any good test stress tests I can run for my GPU, CPU, and RAM. I have downloaded prime95, LinX, memtest (I could not get my memtest to run off of the usb (I set the boot priority in the bios to boot off of USB-FDD first but it still didn't run) also in cpu-z my radeon 6950 doesn't show the core clocks or anything other than the type of card it is ie 6900 series I was wondering if anyone knew how to fix this. Thanks

One last thing I was just curious to see where I stood and what I should be expecting with temps if everyone could post up their core temps 0-3, Frequencies, voltage and processor (preferably i52500k but feel free to post up others). Sorry for all the questions and If i have this in the wrong forum I am sorry but I figured since all of this has to do with an eventual Overclock I felt like this was the best place.

No one?? Well I remounted my heat sink threw some new thermal paste on this beast and these are the temps in Prime95 (Large) 42 47 51 41 0-1-2-3 respectively. SO I dont know I I just dont see why there would be an 8-10 degrees difference between core 0, 3 and 1,2 ?? any thoughts

i think this amount of difference in temperature is common, you don't seem to be going above a 10C difference in temperature.

Is it the same way in your bios? It may be your software.

Hiren's boot disc and almost every linux distro that i know of come with a copy of memtest on them, there is a program called Yumi that will automatically download and make a bootable flash drive.

Edit: just wanted to throw this in from another thread:

3 of my cores stay within 5C of each other under load while the 4th strays somewhere between 10-15C lower. Reseated and reapplied thermal paste four times, reinstalled bracket, followed proper instructions with applying thermal paste for the 920 and even tried lapping the CPU...has to be the chip in my case and most likely yours as well. In one instance before doing all of the above it reached 20C difference but now typically stayed within 10C.

Pretty much all the 2500 and 2600s have one core that is different from the rest (by up to 10C) - it is completely normal.

Thanks for the replies guys! I read that forum but Mine seemed a little off but This is also my first build soo...! Guess its time to see what this processor can really do.
