7700K and H100i V2 (CPU Temps going high)

neutronfckingamin · Sep 5, 2017

Hi, So I just bought a PC. I know the guy who bought it and I know he connected all parts well as I checked again after.

Room Temperature 22-32
CPU Temps on idle 32-48 but sometimes strikes to 50-60 for like 2secs and I see that the voltage goes high like 1.26v.

H100i V2 while playing games sometimes hits 85C

BIOS Settings:
XMP Ram 3000Mhz
The others I don't really know I don't know a lot on BIOS Stuff.

PC Parts:
7700K with H100i V2
Corsair Vengeance RGB RAM 16GB (8 x 2) 3000Mhz
Gigabyte G1 GTX 1080
ASUS Z270G

Thanks!

I7 is known and popular for its overheating

well you are getting 50'C while gaming i dont call that bad its very good
what are your full load tempratures?
and while at full load the temprature of Corsair H100i in corsair link software show us the screenshots

Those are excellent temps. You have absolutely nothing to worry about. Anything south of 90C is safe...south of 80C is ok...south of 70C is ideal. You are golden at less then 60C.

You consider 50c high? My 7700k hit's the high 60s low 70s gaming. 50c is perfectly fine. What does it get during a stress test? 1.26v is more than you likely need for a 7700k at stock clocks but it is nowhere near dangerous.

I'm going to throw a simple statement out there:

The TIM that Intel uses between the die and the heat spreader is garbage. My friend has an i5-7600K, no overclock, on a Cooler Master MasterAir Pro 4 (basically a successor to the Hyper 212 Evo), and he hits and sits around 60C (ambient temp is around 23C) in some games. It's saddening, but true.

Sezmia :

Well the paste under the IHS is terrible. But 60c in gaming is fine, you think that's bad? Why? Quite good for kaby lake, I doubt a skylake i5 at the same clock would run any cooler under the same load.

atomicWAR · Sep 5, 2017

@sezmia the TIM is horrid no question....but his temps are good considering. Many users are not nearly as lucky as the OP when it comes to low temps.

Sezmia · Sep 5, 2017

I'm not saying his temps are necessarily bad, I was just throwing a statement about the TIM.

@Dunlop0078, 60C itself isn't terrible, but I'm just afraid to see what his temps would be if/when he decides to overclock.

Sezmia :

Well you just wont get a lot of headroom for OC with a single stack 120mm air cooler on these chips. I use a 212 evo with a 7700k and I have it undervolted at stock clocks until I bother to delid it. I can overclock within the acceptable temp range, but I just dont like playing games with my cpu in the upper 70s and mid 80s the entire time.

That's understandable.

Ahh!! I made a typo xD While gaming well max I got after installing drivers again and updating few was 83C is that good? I have to take photos when I get back home

atomicWAR · Sep 6, 2017

83C is acceptable but not ideal. For that i'd say less then 70C. But your using an AIO liquid cooler and for that your temps still aren't bad. If you had a open loop cooler I would expect that temp to be a full 10C cooler, but you don't so you shouldn't stress it. I'd aim to never exceed 85C...less then 90C is within CPU spec for safety. However higher temps to wear out chips faster. You should get at least 4+ years though...save any motherboard/PSU failures which can take your CPU with them.

atomicWAR :

I'll have to send some screenshots after.

From the Corsair Link the H100i V2 hits 40-50C when gaming.
I'm scared that the Radiator/Pump is getting hot.

Also how much does the ambient temperature affect the CPU Temps? by 10/15 ?

atomicWAR · Sep 6, 2017

neutronfckingamin :

Depends on the temp. Generally speaking as ambient temp goes up so does idle/under load temps. If your room was 10 to 15C hotter then you lower idle/load temps were the first time you test you may well have your temps increase by as much.

mdd1963 · Sep 6, 2017

85C while gaming is quite warm, but, I'm unsure of what a 7700K's normal performance with that cooler would be.
(the 7700K on air hits a peak of about 60-62C while gaming on conventional dual stack heat sink air cooler, albeit a big Noctua NH-D15)

atomicWAR · Sep 6, 2017

mdd1963 :

7700K has a bad reputation for spiking over 90C even with a good cooler, though all users are not affected. It's the whole bad TIM thing again. This is why Intel recommends you don't overclock their overclocking chip...so backwards.

mdd1963 · Sep 6, 2017

I've certainly seen a few 7700K complaints...; I guess I got relatively lucky with mine.

The trick is make sure no one uses inadequate small AIOs, or, coolers from older 65 watt CPUs, or uses too much paste, etc. But, yes, some will demand a delidding to come in line with expected temps.
