Hi, last week i finished my first build, but it runs way too hot.
idle is 30 degrees per core, but gaming ranges from 45 - 72 degrees

i have an NZXT phantom full tower case, with the 4 stock fans http://www.nzxt.com/product/detail/34-phantom

I7 4770k (3.5 GHz) with stock cpu heatsink/fan
MSI R7950 twin frozer iii 3Gb Gpu
Asus Z87 PRO
8Gb corsair vengeance RAM (1866 MHz)
750w corsair 80+ gold PSU
2Tb Seagate barracuda HDD
120Gb Samsung 840 evo SSD
generic disc drive reader/writer

I am probably going to get a 200mm cooler master fan on the side, but i don't think that would solve things. Are should i get more fans? replace existing ones?


TL:DR - cooling/fan advice general

looking for cooling primarily, don't much care about noise in comparison. if there *has* to be a colour, the case lights are, blue, so i'd like a fan to match that, but no biggie if it has no lights

Is it the CPU temperatures or the GPU temperatures that are getting that high? If it is the CPU, I'd start by replacing the CPU heatsink/fan. The stock heatsink/fan tends to give mediocre performance.

I have a Cooler Master Hyper 212 Plus on my I5-3570K, overclocked to 4.2 GHz, and the highest I have seen the temperatures on it go are about 60 C while gaming. Haswell processors (your I7-4770K) do tend to run a touch hotter than the Ivy Bridge (my I5-3570K), but any decent aftermarket heatsink/fan should be able to handle your processor stock, probably even overclocked.

I just built a 4770k computer and had nearly the same problem. While I was looking it up, I learned that I just put my nh-d14 on wrong, but another thing I learned is that the stock cooler is not (*EDIT* It's enough, but having the CPU that hot is really bothersome) really enough for Haswell in general. I mean, those temperatures are safe, but I wouldn't stress test or overclock or anything crazy with that. Better off getting a hyperevo 212 if you aren't overclocking. Just expect some pretty high temps with this cpu.

Either the Hyper 212 Plus or the Hyper 212 Evo should fit your case (both stand 159 mm tall, your case lists CPU cooler clearance of 170 mm), but it would be a close fit.

I'd definitely recommend the Hyper 212 Evo over the Hyper 212 Plus, though. The Evo has a redesigned base with no gaps between the heatpipes on the base, which should improve cooling over the Plus.

Hmmm. reviewss on the 212 (evo and +)seem good, i'm leaning towards the EVO. Only problem is it would mean i couldn't have a fan on the side. the two stock ones on the case seem to be faulty (or the fan controller is (for those 2 only though)), so intake is poor. What is the best way to solve this? I can't find any fans less then 30mm thickness (for the side slot), so options are to plug the three pin side fans into the 4 pin MOBO fan sockets, or get a front fan as well as the 212 EVO? or put an intake next to the top mounted out take.

PS. does it matter what thermal paste i buy?

With the computer off, try spinning the fans manually, listening for any noise. They should spin pretty easily and freewheel for a couple of seconds. If they don't, you may have bad fans.

When I bought my Hyper 212 Plus, it came with thermal paste. It's a pretty good midrange performing paste. Most thermal paste comparisons I have seen show a couple of degrees difference between the best and worst performing pastes.

at the moment, they are my only intakes, and they aren't a bother, so long as they are plugged into the fan controller, even if it doesn't work properly for those two.

I've ordered a 212 EVO, thermal paste and an extra fan for the 212 for a push-pull system, and i might buy a 140mm fan for a front intake in future, but i'll see how the 212 does for now. delivery is estimated to be 18th

I tried to install the Hyper 212 evo a few days ago, but i couldn't seem to do it. can anyone suggest a good installation guide? i looked, but none helped me. Are you guys sure that it works with socket 1150?

The hole spacing is the same for Socket 1150 as it was for 1155 and 1156, and plenty of people have either the Evo or (in my case) the Plus installed on the other sockets. Is the heatsink hitting something when you try to install it?
