I5 3570k temp issues help!

Hi Just installed my i5 3570k the other day with a H70 liquid cooler (with 2x fans á 2k rpm) and when I run the Coretemp program I see that my core's temp vary quite a bit.

c1 c2 c3 c4
36 21 34 31

One is cool like crazy whereas the other are a bit more hot, especially the first core. Should I worry about it? or what shoudl I do?

Thansk in advance

  1. these are Idle temps btw
  2. my 2600k is similar

    about 10c difference between coolest core and hottest core when idle

    what are the load temperatures?

    thats the important ones
  3. Where is the problem?

    Those temps are more than fine. As long as idle temps doesn't goes beyond 50 celsius I wouldn't be scared.

    With stock cooler the temps are around 40 celcius. Try to monitor under load and if those goes beyond 67 celcius then you might consider to check if you have corretly installed the cooler.
  4. well I'm still w8ing for my gfx cards so I havent played any demanding games more than tf2 but the temps doest change that much , barely above 40 degrees.

    Not sure if I want to run prime95 as I A. dont know how long to run the program and B. I'm a complete newbie on OC and all programs that follows with it.

    Thanks btw for ur responses
  5. i am not a great fan of running prime95 for hours on end to test stability

    just run it for 10 minutes

    within 10 minutes you will see if your cooler is working properly
  6. k Ill post the results l8 then
  7. have let prime 95 run for 17min and these are my temps

    Great results. You do not have any problems with the cooling. :)
  9. so the 10 degrees difference is no problem? cuz I want to OC it in the future so thats what's worrying me

    Temperatures under load that stays below 67.4 celsius is great. Ivy-bridge CPUs Works best under that temperature. At most times your CPU won't even reach that temperature you got now at stock when you overclock it. There almost aren't any apps that makes your CPU go to 100% usage in real World usage right now, so you'll be fine. :)
  11. No clue why one core is so much cooler, but your temps are great! Thinking I should get one of those coolers and put my air cooler on my wife's comp.
  12. Your Temps seem fine and core Temps will stabilize with prolonged use.

    There is nothing to worry about
  13. Thank you all for helping me erase my doubts, I am truly grateful
