I just put together my rig and everything seemed to be alright. I decided to run a prime 95 test on my computer and the CPU would instantly jump from 28c at idle to 100c. I have the Corsair H60 and my CPU is the i7-4790k. I already checked to make sure that my pump is getting the 12V of power it needs and I already tried reseating the cooler. The pump and fan are both working fine. If you guys have any idea what I can do to fix this, I'm all ears.
 
Not very familiar with water coiling but it sounds like the coolant is not moving. It should be running a bit cooler at idle too. When a load is applied it can't handle it. Dumb question but did you apply thermal paste?
 
It can really only be one of two things: the cooler is not seated well, or the cooler is not working. I see you have checked the pump and fan and you are sure it is working? Does the radiator get hot? For it to instantly jump to 100 degrees I presume the radiator is not even getting slightly warm as it is clearly not doing it's job at all. Ok then if you have checked the above, can I suggest changing power source to the H60. You can sometimes use molex for power, or alternatively use a different fan header. If I think of anything else I will come back!
 


# i have read that people have had issues fitting the cooling plate make sure the the heat sink is covering the CPU fully with lots of heat sink compound some said they used the whole tube that came with it, they had the same problem, when he took it apart he found the that the cooler was half on half off sorta, i remember that some heat sinks can only be put on one way. Make sure it is set flush even if you think it is double check,

I haven't had much experience with this subject except for this instance i mentioned.

I assume you need to apply firm pressure, like when you put ram in, click!!

h60 is a water cooling device for the cpu right?

Have you check cpu voltage aswell but i think this should be auto detected?
 
http://youtu.be/HO9APx2yKrg check out this link make sure you seat the all the mountings flush, so the unit can fit together properly including the risers so everything screw together properly, but you probably have it sorted already!
 

Yeah, there was thermal paste on there originally. I even removed the paste and repasted with Arctic silver without any change in performance.



The radiator gets pretty warm. The tubes, one of them gets pretty warm and the other is relatively cool. I'll see if I can connect a molex for power and see how it goes

 
 
Look for a high quality vane axial fan and go back to the good old days, check out some of the aerospace firms, and i considered making my own custom heat sink!, i heard of some crazy cooling options such as using a spot cooler, which actually uses and air compressor but can achieve temperature below -0c but i dont know how you would incorporate that into a home pc!
 


I have the Gigabyte Z97X-UD3H. I'll check if there is any BIOs update for my mobo

Edit: No luck unfortunately.
 


I've already disabled any sort of power management for the pump and there hasn't been any difference.
 
Ok, first off, the original paste is very high quality, easily equal to the arctic silver, and does not require @200 heat cycles to cure.

Second, the cpu fan should be attached to cpu_fan, and the pump to either molex or preferably cpu_aux and no control software, enable 100% duty cycle if cpu_aux is controlable in bios.

Third, when installing a pump, use a pea-sized dab of thermal paste, after making sure the backplate/spacers are correctly installed. Gently attach the pump with the required twist lock, then tighten down the locking ring, using a 'X' or 'figure 8' pattern, not a circular one. The 4 mounting screws should only be turned 1/4 turn at each, by finger until all 4 are really snug, then 1/8 of a turn until your fingertips are screaming and you are considering getting a screwdriver. Do not tighten 1 screw at a time, tighten all the screws at the same time.

Unless you touched the copper plate, or the lid of the cpu and left oily fingerprint, or unnecessarily moved the pump after it made contact with the cpu, you should be good. If you did either of the above, start over, you just messed up the paste.
 
The cooler is just fine, its a 180w unit, equitable to a CM Hyper212 EVO. Unless op is pushing 4.5+ OC, he shouldn't be seeing 100° temps under prime95. I only see 74° @4.4 with a h55. Op may see upto 10° warmer than that as the arctic silver is not cured yet + his cpu has higher TDP, but thats also at 4.3-4.4 OC.
 


# so that leaves a few things! has he mounted it correctly, has i put the fan on the right way i assume theres some difference in flow from push to pull! Does he need to run a pull push system? What do you think. Maybe he should put another cas fan in if he has only one which he replaced, or he should wait to see what happens when the paste has set, so,e say the paste you get in the box is better than stuff you buy cheap!
 
Prime95 is a bad choice to stress Devils Canyon. It will run TOO HOT approaching 100C. Try Googling this and you will find countless people complaining about the same situation regardless of their cooling set-up. Use Aida64 stess test instead. Haswell seems to do much better with it.

And if he is idling at 28C I'm betting he is good to go. Its just the nature of Haswell/DC. It just isn't made for Prime95. Prime is too intense for it.
 
Prime95 will run a cpu to 115% on all cores simultaneously. IBT is even worse, pushing to @125%. Its why it is used by oc'rs for stability testing. If you can pass prime95, you can push any game and not crash. As far as temps go, with that cooler, even a DC shouldn't hit 100° at stock speeds, on a stock cooler, yes, h-60? No way. I'm thinking either a bad paste job or the pump is installed incorrectly.
 


I installed the pump exactly as the corsair installation video. Also, the paste job is most definitely fine, I'm confident in my repasting abilities to not mess it up. With aida 64 stability test though, the temperatures start at around 70 degrees slowly climbing to 90s after 5 minutes or so.
 


Yeah the fan is mounted correctly, I have good airflow from intake fans. What do you mean the pump being tight?
 


Okay, so I decided to take off the Corsair H60 and use the stock cooler, and when I run prime 95 and aida 64, the same thing happens, is something wrong with my cpu?
