Hey,

Been looking all over the forums for a consistent answer for cooling a Skylake i7 6700k but finding it hard to decide. I am planning to do some O/C.

I am torn between Air & Liquid cooling. My worry for Air, the shear size of the decent coolers... Would a Noctua D15, Dark Rock or a Phanteks PH-TC14PE fit in my case?

or is the Corsair H75 better than all the above which is what I am edging towards?

Could someone please offer some advise what cooler would be sufficient?
 
Personally I'm not a huge fan of the AIO water coolers, in my experience they aren't as quiet as a decent air cooler (although the high end ones do offer better cooling).

Your case supports up to 161mm coolers, so these would all be suitable:

https://www.overclockers.co.uk/alpenfoehn-matterhorn-white-cpu-cooler-hs-051-al.html
https://www.overclockers.co.uk/raijintek-ereboss-high-performance-cpu-cooler-hs-000-rt.html
https://www.overclockers.co.uk/noctua-nh-d14-dual-radiator-cpu-cooler-hs-011-nc.html

Etc.
 
That's 4mm too high, unfortunately.

The H75 will most likely perform a about on par with a good air cooler whilst having a much smaller footprint. However it also has more points of failure (pump, fan, tubing etc. vs. just the fan).

Even the relatively small and very cheap Raijintek Aidos is overkill for an i5 6600K at 4.5GHz. I can't imagine things being much different for the i7 6700K.

4mm :(

Ok many thanks Raikiri for you advise. I still not sue what i should go for now :) I want something that is gonna cool my 6700k @ 4.6 and do a good job. Some of those heatsinks seem quite small and i am not convinced they will be as good as a H75.

So some of these smaller heatsinks will be sufficient? They just look so small and @ 30-40 seem a bit cheap compared to the bigger heatsinks. I read on here somewhere that why spend so little on a heatsink when you have a 300+ cpu.

I use actually noctua nh-d14 on my 6700k, overclocked to 4.6, and it is whisper quiet.Temps with prime95 wont pass 70 degrees with voltage 1.285. Strongly recommend.

Some, but not many. The Raijintek Aidos is an exception to the rule when it comes to 80mm HSFs as it matches or beats most other 120mm HSFs under £40 in independent reviews.

Mine keeps an i5 6600K running at 4.5GHz below 65degC (ambient of 20) when gaming or video converting with all 4 cores at 100%. That leaves around 30degC headroom before thermal throttling starts to kick in. I've never got anywhere near close except when deliberately stress testing.

Take a look at some comparative reviews. Anything on a par with or better than the Raijintek Aidos should be fine...

Thanks everyone for making my choice that little bit easier now. I not really up to speed with coolers so not really sure what is best to go for but think i have narrowed it down to either the Noctua d14 or the Corsair H75.

Aint this particular Noctua pretty old now?

https://www.overclockers.co.uk/cors...iquid-cpu-cooler-cw-9060015-ww-hs-024-cs.html

I guess this is down to personal preference, i just want the best performance i can get for 70-80 sheets. The Noctua looks ugly in comparison to H75.

If you had a choice between the 2 what would you choose? Forget all the maintenance of a H75 (Pumps, tubes etc) just outright cooling i am after?

Thanks again guys
 
Antec H600 with i7-6700K @ 1.366 Vcore, 4.7GHz = 60C Cinebench/Realbench temps.

Some systems may have Load-Line Calibration quite high to get higher temps, or case airflow may not be so good.

Did you keep the stock fan and did it come with 2 fans?

i am guessing you can add another fan for push/pull?
