i7 4770k Too Hot

I just bought an Asus Maximus vi hero motherboard and an i7 4770k processor. By default the CPU was in turbo mode. The temperature was up to 88°C. I am afraid it is hurting it. Would this show that I installed something wrong? Do I need more than the regular thermal paste? I will not boot the computer until this is figured out. By the way, the case fans are connected to an external regulator not the motherboard. Thanks!

  1. Best answer
    Try connecting the fans to the board. Your system is probably just not telling the CPU fan to kick in as it should. The external regulator may not be working/set up properly. And yes, 88 is WAY too hot. It can certainly damage your system.
  2. What cooler are you using?
    Maybe your sensor could be faulty
  3. Plugged in case fans and I am now getting a steady 40-43°C. Is this a good temperature?
  4. Why would plugging in the case fans change 88 to 40? Doesn't really make sense. By case fan do you mean cpu fan?
  5. I have an h100i and I idle at 30 degrees. 40 seems a bit high. Maybe ambient temp difference. It's safe, but can be improved.

    Yes. If I said case fans I was mistaken. I meant CPU fan. Is it connected directly to the motherboard or is it in the external regulator? Because you DEFINITELY want it connected directly to the mobo in the alloted CPU fan slot.
  7. It HAS to be connected to the CPU-FAN header on the mobo. It's near the cpu fan.
  8. Nope, case fans are in and it is running just fine. Would new thermal paste/higher wattage PSU fix anything?
  9. Cpu fan is for sure connected to the motherboard. Working fine now

    Exactly. Anything else won't work.
  11. Glad it's fine now. What's your idle temp?
  12. If you want to check it, make sure you have a good idle temp and run a CPU stress test. Sandra is a good one. It's a free download. Just keep an eye on the temps and be ready to shut it down if it goes beyond it's limit.

    It idles about 30-50°C
  14. That is a HUGE range for idle. You should hover around the mid 30s or so.
  15. How about you leave it idle for a few minutes?

    That's in the neighborhood I would expect it. And 2 degrees is acceptable range.
