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!
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.
Why would plugging in the case fans change 88 to 40? Doesn't really make sense. By case fan do you mean cpu fan?
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.
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.
