High 7700K Temps with Corsair Hydro H80i and Hyper 212?

Hi All!

I did a new build about a month ago and I have noticed some unusually high temperatures with my 7700K.

I originally had a Hyper 212 cooler on my build, but after seeing the temps I decided that maybe it wasn't cutting it so I switched to a Corsair Hydro H80i v2. However the temps are basically the same with either cooler!

Turning on XMP in my bios is also causing temperatures to jump even higher. I am turning on XMP for my 3000 MHz ram, but I also notice it overclocks my 7700k to 4.5 GHz. I have been using a combination of OCCT and RealTemp for stress testing and temp readings.

Here are my temps:

No Overclocking at All

Idle: 26c - 32c
Full Load: 65c - 72c

------

XMP Turned On (Which also overclocks 7700k to 4.5 GHz)

Idle: 36c - 45c
Full Load: 75c - 85c

------

Like I said, these temps were basically the same (give or take 2c-4c) whether I used the Corsair Hydro H80i v2 or the Hyper 212 coolers. I have re-done the mounting and thermal paste (ARCTIC MX-4) at least 4 times to insure that I did not screw that part up. I also have the latest bios update for my motherboard.

Are these temps normal? I really thought going with the liquid cooling solution would make a huge difference.

Here are my basic system specs: 7700k, Corsair Hydro H80i v2 Cooler, ASUS Prime Z270-A Motherboard, 16GB Corsair Dominator Platinum 3000MHz, GTX 1070, Multiple case fans
 
Why is XMP causing your CPU to OC? And why to 4.5GHz? That's your CPU's default boost clock. Sounds to me like something funky is going on in your BIOS.

Yeah no idea. The original bios and the most updated one both do the same thing. Basically when I use XMP, it bumps up the voltage in my CPU causing higher temps, but also I am getting the full speed of my DRAM.
 
7700K are notorious for being heaters. Even with custom watercooling they are a pita to tame their heat output. Owners are resorting to de-lid them to swap out that crap TIM intel used.
 
Manually set your CPU voltage settings. CAMP profiles don't care much about temps, only stability, so default voltages tend to be pretty high.
 
Recommend a delid. I'm using a H110, but 5.0Ghz gives me 80's under prime AVX load, OCCT and Realbench barely hit mid 70's.
 
yup, well, delid will probably give you -20c temps, but it doesn't mean that your chip will clock higher if it's already doing the best it can. My system runs 4.8 stable, 4.9 unstable, and 5 crashes under load, all have low temps and plenty of voltage, so I just decided to keep it at 4.8 and that's it.
sad overclock imo, would have liked 5.0

Coming from my 2600k that was doing 4.4 (1 ghz oc), getting just 300 on a 4.5 chip is disappointing.
 
temps are a little warm, but if you're only gaming I doubt the temps will be quite as high at full loud. I'd say you're fine.
