Hi community

I have recently installed an i7 4790K and it is working amazingly fine thou I would like to tone down the load temps by 10C .

I currently have an Cooler Master TX3 with a Noctua NF A9 92mm and the motherboard decides the best speed for the fan.

The cooler gets the CPU cores and threads at idle to 31-41C.
Under load the cooler get the CPU cores and threads to around 60-63C while playing Witcher 3 or Fallout 4 near ultra at 1080 60fps thou after an hour or two it will be around 60-69C and maybe flicker to 75C at the really odd occasion but it is mostly at 63C.

I have a full tower Corsair Obsidian 750 Windowed case and there isn't a lot of room between the back exhaust fan and the allocated CPU socket location.

Could I get a list of decently quiet but very cool CPU coolers.
Also I'm still unsure about closed loop coolers as I do not want a few months in for a leak to spring and damage my very expensive pc. Liquid and electronics do not mix...

Cheers!

I can personally recommend Noctua NH-D15S, about the best performance you can get with a air cooler for cpu. It is huge though, but should fit your case. Cryorig R1 is about the same in performance. If you need a more budget option Silentium PC Fortis 3 (Malik edition for custom color) isn't too bad, a few degrees worse then Noctua with overclocked 6700k.

I use a D15S on to cool that chip overclocked to 4.6GHz. (Temps are fine, but voltage is too high for 4.8Ghz) The RAIJINTEK Pallas also gave me temperatures of 60C or less and 30C idle at 4.6Ghz.

The i7 runs reasonably warm and 50C load for Witcher 3 or Fallout 4 is very optimistic. I'd stay where you are now unless you plan to overclock, and even then, that's a 'light' motherboard and you could run out of voltage before you run out of thermal margin.
 


Naa no need to overclock, the i7 doesn't even find the game challenging to run. I may have a few hiccups with Fallout 4 but that's Fallout so I'm not bother really.

Its just the little cooler has to work hard to keep a leash on the temp and if I had kept the cooler master fan on it would be very loud, good thing I put a Noctua fan on it instead which I order a long side the i7.

I would just like the temp and sound level down a bit, it not super loud but just rather audible.

Cheers!
 
Including the builds we do at school, I have used CRYORIG H7, RAIJINTEK Pallas, Xigmatek Janus, and Noctua D15S on that chip. The Janus is the loudest, the other three are quiet enough for me. Even the stock cooler works OK.

Under intense benchmark load and not overclocked, all of them exceed 55C, but are still quiet (quieter than the GPU cooler in all situations and cases)
 
What about water cooling, I've heard they can get a CPU down to 40-45C? Are there any single 140mm ones out there that don't have a history of leaking after 6 months or so and have an easy install?

I'm not a fan of Corsair loud cheap fans, I don't want to buy a water cooler than have to pay and extra 1£15-20 for a better fan.

Not sure you would get any better performance with a single 140MM water cooling unit compared to NH-D15(s) or similar air cooler.
