6700k temps are too high

[klooless]

Hi guys,

I have posted a topic last year regarding an issue that I had with "unreliable CPU temperatures". I decided to take of my H110i GTX, clean it, put a new thermal paste on my CPU and increasing pump speed to max preset, It did the trick of couple of months and temps were maintained at 60-70c @100% using my old overclock profile.

 

Now, things are much worst. Below are my idle temps running at stock frequencies.

Does it confirm that my H110i is faultly?

 

 

 

 

 

 

system specs

MOBO	MSI gaming M3
CPU	6700K @4.5
GPU	2x Fury X crossfire
RAM	Ballistix Sport LT 16GB Kit DDR4 2400
PSU	Cooler Master: Silent Pro Gold 1000W
CPU Cooling	Corsair Hydro Series H110
HD	M.2 Samsung 950 PRO 512GB/ 540 Evo 500GB
Monitor	BenQ XL2730Z 144Hz 27
OS	Win10 Pro
Case	Corsair Carbide Air 540

i would personally try and reapply the thermal paste, and see if it has any effect, before running out and buying a new cooler.

It might be faulty. The temp seems to be too high for a liquid cooler. It's normal on the stock cooler.

 

These all-in-one liquid coolers don't leak as much as their open system brothers, but noticing a leak is much more difficult. Still, reapplying thermal paste is not that costly, so give that a try.

What is your ambient temperature?

I don't see what's unreliable.

 

The temps look fine (without knowing the ambient temps).

Looking up your CPU/Cooler combo in google gives the same result, sometimes hotter due to different clockspeeds.

You're within safe temps.

Buy a delidding tool and replace the cheap stock stuff that is between the die and IHS with this:

You'll gain (lose) 15-20 Deg C

What are your idle temps?

I say this because while the H100i is a fine cooler, it's still just a small 240 AiO and it isn't magic.

 

With a high enough overclock, I could get my 6700K to over 80C when stress testing on my old H100i.

That wasn't what it would always run at since it would idle at around 35C and real-world loads would see it at temps around 50C-60C.

If you're running your 6700K at 4.5Ghz, then you're right about in the range.

 

So, before you do anything risky like delidding your CPU, try lowering your CPU's VCore voltage just a bit, and also reset your expectations on what can be reasonably expected from a 240 AiO.

At the same time, remember that stress testing tools put an artificial load on the CPU that won't ever be matched by any real-work workload. Maybe video rendering could tax it, but even that kind of load isn't as bad as what the likes of Aida64 can do.

I would delid it reapply thermal paste and watch the temps drop. And if it's still high, then get a new cooler.

Sure, i'm thinking about doing that, any recommendation on a specific thermal paste brand?

I have an A/C in the room, I would say 21c on average. both my GPUs run 26-30c idle, 50-55c load

Sorry but im not sure about getting 50c on idle and more than80c at a stress test when im running at stock configs..my PC sounds like a vacuum cleaner when I run CPU intensive games such as GTA V which never was the case before!

Not worth it IMO

Yep you are right, I used to get 25-35 at idle and around 50-60 at load with my 4.5 profile. now im getting 50 at idle and 80+ at load! using stock profile!

Okay, I would definitely suspect something went wrong with the H100i.

If you used to get those temps before and now your temps are looking ~30C higher, with nothing having changed since, then yeah, something is off.

 

If you haven't removed and remounted the H100i, or really done anything, since this new spike in temps, I would contact Corsair Support about it.

I know what I can reasonably expect out of the H100i on a 6700K and idle temps in the 50-60C range is not right.

 

So yeah, contact Corsair Support and let them know what's going on. The warranty might come into play here.

I just took the whole thing apart, cleaned eveything with a thermal paste remover and applied new paste.. and im back in business!

 

I took this when I was doing a stress test. got my vcore =1.27@4.5
