When i originally got my 6700k i used a Corsair H60 as its way to cool it off. I noticed the temps were at nearly 90 degrees Celsius while i was playing the division, so i replaced the thermal paste with IC diamond and it lowered the temps by about 20 degrees C. I decided maybe the H60 wasn't cutting it for me, so i upgraded to the H115i as the new water cooler. Now the temps when I play the division are around 50-65 degrees Celsius. So i went to research what other kind of temperatures people were getting with the same CPU and the same water cooler. Other people were overclocking their CPU and weren't even reaching 60 degrees celsuis on full load. Where as my CPU reaches almost 95 Degrees celsuis at full load with no overclocking. I really have no clue what is wrong, I've tried everything but nothing seems to fix this heating issue.

Double check to make sure that your CPU block is mounted properly after making sure you don't have too little or too much paste on the chip. After that make sure your fans are spinning at the correct speeds. If they are, go into your BIOS and make sure your vcore voltage for the CPU isn't set too high by default. ASRock and Asus mobos are very prone to this. Also, at full load are you running a game or a stress test? And for the others that have OC'd their CPUs, are they stressing them at the time of gauging temps? Or are those idles? Also, if running Prime95, small FFTs will produce more heat as compared to the blend test overall because it will focus on your CPU only. Whereas the blend test will stress both CPU and RAM at different times.

The water block is on correctly and i do have the right amount of thermal paste, My fans are running at max speed. At full load i was running Prime95 small FFTs, and the other people were running stress tests like me while overclocking and not getting my kind of temps. The only thing that makes sense is there could be something wrong with the CPU.

I would disagree with that conclusion. Your temps are also based on your ambient temps at your location in the world. Something else to look at is whether or not your case has good airflow and to double check that the pump in you AIO is not shot. If you cable management sucks, then that will add airflow restriction to the case as well. Also, what speed are your fans at and what size are they? Supplying a model would help here too.

Here is a picture of my case as you can see i have very good cable management. The fans are dual SP140L PWM, and they're running at around 2000-2600 RPMs. Now how would i check that the pump isnt shot? PS the picture is when i had the H60 in the computer, i now have the H115i but it looks basically the same. http://

If you could use CFM fans and not static pressure fans for all of your case, except the AIO, that would be better airflow for you. But, one thing I haven't mentioned is your vcore voltage for your CPU. If this is too high, which it can be by default (even with no OC), then you will have higher temps no matter what else you do. If you are over 1.4V, I would seriously suggest lowering it to below 1.375V. If you can provide pics of the temps at idle and at load while having CPUID running and up at the same time that would be super helpful.

Ok here are the pictures, i have the idle temps, blend test temps, and FFTs temps with CPUID open with all of them. http://

Do you have your CPU voltage (vcore) set to a static voltage? Or did you change it from run to run?

I haven't changed any voltages or anything, All i did was plug in the CPU in the motherboard and put the H115i on it and never touched any settings other than fans speeds.

Your mobo isn't the problem then. I would think about changing to the AXxxxi series, HX series, or RM, series PSUs if you want to stay with Corsair. They have much higher 80+ cert ratings and will provide better power consistancy. I've read that with the 6th gen CPUs you need to sometimes turn off the iGPU part of the CPU if you have a dedicated GPU in the system. That's probably part of why your temps are so high too.

Ok so if I do turn off the integrated graphics and i still have the same Temps what should i do? Because right now i sold my 970 to save money for the 1070, so i need the integrated graphics on. But i've done those tests i've showed you with the temps and i had the same Temps with a dedicated GPU.

When you get a dedicated GPU, turn off the iGPU. That should lower temps. As of right now, you might not be able to get lower temps because your GPU is in you CPU. And I wouldn't consider the old setup viable for comparison because you had the iGPU running while having the GPU running in the system. Now while the iGPU really isn't doing anything when you have a dedicated GPU installed, it will still use the same amount of power and create the same amount of heat as if you were only using it and not the dedicated. Granted, this is a bit worse in the 6th gen CPUs because the iGPU is more capable than previous versions.
