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 water 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

That's fine, so long as you can deal with the thought of potential spills :p I was also considering going for an AIO like the x62 Kraken from NZXT, but when I imagine something going wrong I was just like "nope" and went with the Cryorig H7 instead. Besides the USB 3 port on the mobo being right next to the CPU and blocked by the cooler, it has...

Look at your voltage (Vcore) during a stress test at stock and then under overclock. I know for a fact that ASUS's Suite for overclocking uses *way* more voltage than necessary for a given overclock. It's been like that since its inception with Sandy Bridge. Pretty much the same for other motherboard maker's versions of "convenient" overclocking tools from the likes of MSI and Gigabyte.

I do not have that chip and cannot advise on specific voltage recommendations, but for starters, I would say you are having way too much voltage pushed through at overclock.

Hi! Thanks for the info. I actually went back and edited my post to remove the ASUS Suite's overclocking temps. I kind of just tried out the ASUS Suite for fun, but I am not really looking to do any hardcore overclocking. However even for no overclocks on the ram and CPU the temps seem kind of high for having a liquid cooling solution. Of course turning on XMP in the bios makes the temps go up by another 10c-25c higher. I am just wondering if all my temps are normal for this CPU with liquid cooling. I thought even overclocking I would never hit over 80c. :??:

After doing more research, I have heard that the Corsair Hydro H80i does not really cool much better than the Hyper 212 after all even though it is liquid cooling based. Which kind of sucks because it was more expensive and it's a bit louder than the Hyper 212 I had in there before.

Anyone out there with a 7700K or a lot of knowledge about it have any info or suggestions? :)

7700k temps can simply suck due to the manufacturing of the chip. 85c running occt isnt too bad actually with your cooler considering i have a h115i and my temps arent any better. its just the chip, it runs hot and spiky, so without a delid theres nothing you can do with a lot of them to lower temps.

I'm on a Cryorig H7 with the 7600K at 4.5Ghz but OCCT only managed to bump me up to 80C on full load using the small data set. I'm not even touching the Vcore, having left it to auto it's only reached up to 1.272V. I can maintain my overclock regardless of whether XMP is enabled for my 3200mhz corsair kit, so it sounds like you may have been doing something wrong.

Also it is a misconception that you would see huge differences with a water cooling solution. Water is much more difficult to heat up than metal, meaning it takes longer to transfer heat to it and then away from it. This requires lengthier testing to reach stable temperatures while testing in order to run comparisons.

It works best where you want to cool multiple components at once or want the best OC capabilities, but otherwise opting for a single fan AIO may actually perform worse than a decent air cooler. In the very least I would suggest sticking with the Hyper 212 simply for ease of use and saving time in testing.

I have a GIGABYTE z270 board so OCing probably works a little differently, but what have you touched from the settings besides enabling XMP?

Actually the only thing I have touched was enabling XMP. But I think I am just going to live with my temps since it seems others with the 7700k are getting around the same as mine. But yeah I was under the misconception that switching to water cooling would be a dramatic difference. But oh well now I have room to put in more ram sticks since my Hyper 212 was in the way before. :lol:

Besides the USB 3 port on the mobo being right next to the CPU and blocked by the cooler, it has excellent clearance on everything and superb performance too, don't regret it one bit!

A decent AIO will allow you some more OC headroom but usually only the custom loops with high end parts can really make that difference you envision (and even then i don't suppose more than, say, 10 degrees max). The price for those is prohibitive though so one can only dream of being rich enough to burn money that way :)
