Hello everyone,

I am getting high temperatures on my CPU and looking for help, the build is:

cpu = intel core i7 2600k stock settings and stock intel cooler
memory = corsair 8GB (2x4GB) DDR3 @1600
graphics = evga gtx 1070 8GB
mobo = Asus P8P67 Pro
psu = cm silent pro gold 800W
hdd = samsung 850 500GB and wd black 1TB
case = cm 690 ii advanced
fans = intake 2x120mm bottom, 1x140mm side panel, 1x140mm front
exhaust = 2x140mm top, 1x 120mm rear

I clean the case regularly with a duster and with q tips and alcohol

CPU idles between 57C and 61C, even with less than 10% load, using Prime95 the temperature goes up to 96C, gaming also gives similar readings and even using CCleaner to check registry makes it go to +80C. Other parts like the GPU idle at 31C and drives around 25C

I am using NZXT CAM and Speefan to monitor and both show same temperatures, RPM of the fan is working and I can see the adjustments in RPM on both programs as well from the BIOS

So I decided to change thermal paste, cleaned the CPU and heatsink with ArticSilver cleaning solution and then used ArticSilver 5 on the CPU, put it all back together and same results.

I was wondering what else should I try next, if you guys need any more info please just let me know.

Wheww, 1.34 is awfully high. You should be able to get it down to 1.25v, that should drastically lower temps. 212 Evo is a great buy if you're willing to spend the $40.

You're running the 2600k at stock speeds correct? The stock cooler should cool it just fine, shouldn't be seeing anywhere near 90c+.

It's likely that when you re-assembled the cooler on the processor you didn't mount it 100% correctly. Pressure is what facilitates heat transfer. The thermal paste should be super-thin and just serve to even out any irregularities in the contact between the processor and the heatsink.

Thanks for the answers guys, will re mount again and see how it goes.

When talking about mounting correctly with pressure what does it means exactly? I mean I just like put the cooler on top aligned with the mb holes and then pushed the pins until they clicked and then twisted the top part of each pin to lock.

When mounting should i push first the center part down on the cpu? And then with the other hand push down the pins?

Look at the arrow on the pushpin, they should not be facing towards the heatsink when mounting it.

Ok I think I am seeing the problem: a quick inspection on the back of the mb I see that on the 2 left pins the black part of the plastic is not as far as the white part only half way.

Quick question, in that case that I have to push again, should I just push those 2 down or remove everything again, apply paste and basically do it all over or it is not necessary?

Ok tried pushing the pins and they definitely went lower, went to test and same results.

Right now on Windows with 3%-6% load temp is 57C-61C, Prime again goes up to +90C.. During the BIOS temperature is strangely at 32C.

Will re apply thermal paste again and get back with those results.

Ok so I took everything apart including the mobo to make sure pins were all the way down. re applied paste and exact same results.

Well actually worse since temp wont go lower than 63 C now and Prime goes +90C.

Is a pushpin broken or something? You're using an intel heatsink with a copper slug in the middle correct?

Yeah intel heatsink with round copper slug in the middle. The pins as far as i can tell look ok, with everything installed the heatsink looks secured as in it doesn't move or feels loose

Does your case have a motherboard cut out in the back? Easy way to verify you got all the pins. Exhaust fan in the back of the case? Use AIDA64 to stress CPU, you should be getting around 70c ish on 100% load.

Yep it does, 2 pins are very easy to see the others for some reason are a little bit harder to see but they are ok. When I took the motherboard back I could check 100% they look like the picture.

Is it possible heatsink and fan not doing their job anymore? System has more than 6 years

2600K has the heat spreader soldered to the CPU die, reason why they overclock so well. Point being, you shouldn't be seeing 90c+ unless it's clogged with dust or your voltage is through the roof. You did say you were running at stock speeds though, so.

Yeah stock speed, voltage reads @1.34V currently. Funny thing is I really don't know if the CPU has been running like this all this time since I didn't bother monitoring and have never had a shutdown or temperature warning.

I was thinking maybe about trying an aftermarket cooler but dunno if it'll be worth it, CM EVO 212 is around $41 where I live or just let it work normally until next upgrade, which I am not so sure is really worth it.

What do you guys think?

Lowering to 1.25V definitely help a lot, temperatures at idle stay at 48C-52C great improvement! From what I was reading this boards adjust all of that auto with sometimes not good results. Temperatures at Prime still go from 85C-90C but since that's a stress tes scenario I can live with that for now.

For now since I just bought the video card and the extra fans I will put on hold the cpu cooler, maybe getting later this year as I read they are releasing some backplates for AM4 socket as well to future proof if I decide to go AMD next build.
