Hey fellas!

I just recently build my very first gaming pc and it works very good. It's like building my dream from when i was a little boy. I just have one problem .. my CPU is getting too hot when playing games! Speedfan shows me temps at around 70-85C when playing BF4 (on ultra) My specs are

Gigabyte z97x Gaming 7
intel i7 4790K w/ stock heatsink
8 GB G.Skill RipjawsX (2x4)
EVGA GeForce GTX780 6GB SC ACX
Corsair CX750M
Samsung SSD 840 Evo 256GB
WD Blackl 1TB Harddrive

Also in my case i have two 140 mm Corsair AF140 Red LED fans for intake in front and another 140 mm in the back for exhaust.

My question to you is what kind of cooler i should use for my CPU. I have been looking at the Corsair H100i and then replace the stock fans with some other (suggestions much appreciated)
But what is your opinion guys? :-)

Hello my friend,

Can you please specify what your ambient heat is (for example room temperature)

My room temperature is around 22-28C because it's summer :-)

Ah Summer, Computers worst time of the year (because of heat) right i can recommend you these two choices which would probably be best suited for your situation.

If you've already overclocked or will in the future I'd recommend this:

Corsair H100i Hydro Series CPU Cooler
http://www.ebay.co.uk/itm/Corsair-H100i-Hydro-Series-CP...

A bit pricey but it will do the Job much better than others, (trust from experience)

and if your not going to overclock because your CPU is pretty much a beast already on it's own stock clocks compared to i3 and i5 processors, then simply get this one which is much cheaper than water blocks in my opinion.

CoolerMaster Hyper 212 EVO CPU Cooler
http://www.ebay.co.uk/itm/CoolerMaster-Hyper-212-EVO-CP...

Anything else you want to add?

Yea i want to know how i should mount the fans in the radiator if i chose the H100i. I've seen lots of discussion about whether the fans should push out air through the radiator or be on top and exhaust the air out. Which one should i stick with in my case or what option is simply the best?

good case you could had a bottom one as intake and another on top with the evo 212 or get a bottom one and liquid coling on top see your case user manual page 22 for all the cooling option you have and if you repaste the cooler use mx2 or mx4 they do not need cure time . http://www.phanteks.com/assets/manuals/Enthoo-Pro.pdf

Thanks for the input. Do you use the same case? (if u do i have some other questions) but what fans should i use on a top radiator? and where should i mount them - under blowing air through or on top exhausting air out?

i have a scout one for the water cooling i would put them under the radiator to push hot air out also you case have pwm hub for fan so you could use it .

Well there's your problem. Red makes everything hotter. What you want are fans with Blue LEDs....


But all jokes aside, I have a 4790k with the exact same MoBo and I've been having a difficult time keeping the temps down with both a high-end Heatsink and a Corsair H80i Closed Loop cooler. From what I've been reading around the web, Gigabyte motherboards are really bad when it comes to their default voltage settings and tend to over-volt, causing slightly higher temperatures than what you should be getting. Upgrade your bios and double check to make sure you're not using more than 1.2v on the stock settings. This helped me bring my temps down a little bit (by about 5 degrees).

You also need to accept that the 4790k just plain runs hot. My last CPU was an AMD Phenom II and temps above 50 C were considered disastrous so I almost had a heart attack when I first got my 4790k and found that it was pushing 100 C during stress tests and running in the upper 70s during typical 100% loads (such as video encoding).
