4790k Overheating 80+C

[spartin503]

I've had the 4790k that I have now for about a year and it has always ran hotter than the benchmarks I've seen online, but I figured mine just ran hot. I used to have an H100i and while running OCCT stress test it would be running around 80C. Today I got a H100i GTX and I gave the H100i to my friend. The H100i on her CPU is working fine (3770k with OCCT at 60C), but my H100i GTX hits the 85C limit of OCCT in a few seconds and while running Cinebench it hits 90C in about 5 seconds. I have already reseated the CPU once, reseated the cooler twice and applied new thermal paste each time and it is still running really hot. Do any of you have ideas about what I could do?

What are your ambient temperatures?

What clock and voltage are you at?

 

Can you make sure that the pump is connected, powered and working?

[LRC350]

what is your vcore under load?

 

make sure your fans and pumps are on performance mode under corsair link too.

85 degrees while benchmarking? What are your idle temps?

I think that your pump may be broken or unplugged.... Try switching out the fans and/or running them at 100%, if that doesn't help get a new cooler

Ambient is around 25C, CPU is at 4.4GHz and voltage is 1.2V. The pump is running and the fans are spinning.

Vcore under load is 1.2V, and it is on performance mode.

Try reseating and reapplying thermal paste

Make sure the voltage is actually 1.2v and make sure that you're mounting it properly...even though you've already given it a few good tries.

How are your idle temps if they are also warmer than usually it's a very good indicator that it needs to be reseated.

H100i GTX on a 4790k over here too. Never had it go above 60. Something is seriously wrong in your setup.

Also this might solve your issue

It's not the cooler, I tried it on another computer and it worked fine.

I've already done is twice and I moved it to a different computer and it works fine on it.

CPU-Z says 1.202V under 100% load.

Idle fluctuates a lot between 35C-40C.

Unless your ambient room temps are up in the 25C area that's a bit warmer than most. You might be reseating it off everytime or something might be occurring when you remount it causing the problem.

How's your overall airflow inside your case? That's pretty important

I have 200mm fan in the front of my case, and the H100i GTX in the top, there's no cables in the way of the airflow and will all of the fans at max, and with the vcore at 1.1V, and with my ram set back to default I was able to keep it under 75C.

H110 I and I hit 65 it extream tuning utility at 4.7ghz 1.25v

I think u need some new thermal paste or, some of the h100s don't tighten down enough and u have to add washers behind the screws on the back of ur mobo
