Hi!

I recently did a new build which includes the following components:

- Asrock z170 extreme3
- i5 6600k
- ID cooling Frostflow 240l
- Corsair Vengeance Led (2133) 3000mhz
- 2 Gigabyte gtx 960 4GBs in SLI
- 256Gb Kingston hyperx ssd
- 1Tb hdd
- Phanteks eclipse p400 case
- the 2 original phanteks fans + 2 Corsair AF120 fans

So Im having this problem with my cpu overheating, its OCd to 4,5Ghz at the moment with Vcore set to 1.3V.
At normal load the temps keep jumping anywhere beetween 35°c and 55°c
When running a stress test I must stop it almost immediately as the temperatures go all the way up to 85°c
On Gta V the temperatures go up to ~65°c

Soooo where should I start looking for the problem? The cpu cooler seems fine on the outside. Everything but the second 960 was purchased as new.

I think i atleast partly fixed the problem which was it overheating to almost 90 degrees...
But yeah, it often does something like this: "31c, 40c, 32c, 33c, 29c, 41c" when Im following how high the temperatures are.
The occasion which caused the problem had most likely to do with the cooler head being too loose and having bad thermal paste; who knows if the new fans had an effect on it, too? Atleast I think so.
There's a review of the cooler which says that...

the first step I would take is to remove the overclock and stick it to stock voltages and see what my temps run at! Its completely possible your just unlucky in the silicon lotto. The temps where still screwy at stock! I would make sure the fan for the CPU is seated properly and has thermal paste applied properly.

I reapplied thermal paste this morning. No difference. The water pump has remain untouched, so it should be as it was out the box. This cooler does not come with any kind of program like for example corsairs aio liquid coolers' Corsair Link2. Its just connected to the mobo with a 3-pin connector.
I'll check the max temperatures on stock frequencies and voltage. As i remember it, the temperature was already then higher than it should be - Well, OCing was just stupid when unsure about it, but i've tried and even had it running on 4.8ghz and played Gta V without crashing, temps being a little over 70°c.

Prime95 can cause the voltage to creep up as you let it test, which can cause overheating even if you have great cooling. I'd use AIDA64 or something if you can. If the temps are fine in game, you might be able to just ignore it. If you aren't satisfied with the performance though I'd return the liquid cooler and get a Noctua NH-d15

As I got home I took the computer apart and customized it a bit.
Some time ago i bought two Silverstone fn123 fans to use as case fans. Those fans are 120x120mm and only 15mm thick, so I swapped the stock ID-Cooling fans with them as that made it possible to mount the radiator in the top of the case (the radiator with the original fans is too thick to fit in the top of the Phanteks p400 case as the ram sticks would be in the way, so it must be placed in the front - taking hot air from inside of the case and blowing it trough the radiator - or taking cold air from the outside and blowing hot air straight into my GPUs which isn't that good either considering that there is not too much free space for air to circulate.)
I also bought new thermal paste to use instead of the one which came with the cooler. This probably had a huge impact on the temperatures.
So now that i have the radiator at the top - blowing air out of the case, the two corsair af fans as intake fans in the front and the one random phanteks fan which came with the case in the back as exhaust I get much lower temperatures - even when the CPU is running at 4,6ghz with a voltage of 1.36V - than at 4,0ghz with the voltage set to something around 1.2V
I also did some stability tests with Aida64 without any problems at all, max temps being around 65 degrees Celsius. Isn't that decent?
In addition, the dB levels are a lot lower as the ID-Cooling fans are really loud, but i honestly didn't think that the Silverstone fans would actually work. :D

Thanks to everyone for the advice!

Do you have temperature spikes or ? Some Skylake CPUs have wierd temperature spikes(20 degrees up and down in less than a second)
If with spikes your temperature doesnt exceed 65 thats amazing. But i would not use Prime to stress test it because its brutal and unrealistic.

There's a review of the cooler which says that when they first tried their review product the temperatures were too high, and that was because the plate which comes behind the motherboard sits loose when tighting the nuts up just by hand, and therefore prevents the cooler head to sit tight on the cpu and make it heat up alot more than it should.
However, I had tightened the screws up so the cooler in my opinion sat tight enough, because I knew that.
When I reinstalled it for the second time today, I had no mercy on it - just thought that im going to fully eliminate the chance of it being loose.

What comes to prime95, I think i won't use that program for stress testing anymore, thanks to the good advice I got from here.
