i5 3570k temps to hot?

I have had my pc for 9 months now and the temperature seems to be rising for some reason for my i5 at idle In the bios it is at 45c. I don't understand why this could be I recently applied thermal paste (arctic silver 5). I also build my little brothers pc and his idles at 26c in the same house however his CPU is the i5 4440. I don't know my room temps but I do live in the uk and it never very hot here. I think it's like 18c today. I have a zalman z11 plus case with 5 case fans and 2 92mm CPU heatsink fans (CM TX3). My GPU seems to be getting hotter than it should I set it to aim for 70c but it went upto 80c yesterday. It's a evga 770 sc acx 2gb.

  1. Just ensure that the heatsink screws are tightened evenly; and not over-tight.

    Verify the temps using RealTemp and HWInfo
  2. I have done that however when installing the heatsink for the first time i messed up the pins that kept it in place but it still stays securely on and i can lift the mobo up with it. With my heatsink it has the same kind of pins as the stock cooler. I bent some of the pins on one side soi had to bend them back to fix the heatsink on.
  3. In BIOS your CPU will run at full speed, so higher than usual temps in BIOS is not a problem. Load temps are what matter. 80c is fine for a GPU at full load, and 70c should be the max your CPU should get while at full load or running prime95.
  4. using prime 95 my cpu went upto 66c and using Unigine Valley for my 770 i got up to 76c. this i sannoying me i used the evga tool to set the temperature to 70c but it still goes higher. Do you think i would benefit from a full custom loop.
  5. In almost all instances water cooling will be better than air cooling. (Worst case it will be equal).

    I'd say you're safe with those temps. and EVGA precision didnt work for me either, I used MSI Afterburner and it worked for me.
  7. k thank you both for the help I think I will water cool my pc i always liked the look of water-cooled PC.
