Single 240mm for 9900K and 2080?...

Recommended Posts

Posted · Original PosterOP

So I'm cramming some pretty high end components into a extremely small case. I was planning on air cooling it however after some thinking I believe it would be possible to do a custom loop. I could get the case extension and add a thick 240mm rad and use higher quality components and put both the CPU and GPU in a custom loop. The other option would be to leave the GPU air cooled and throw a AIO on the CPU?


I would prefer air cooling the CPU as well and I'm going to try I just don't know how well it'll handle temps.


Go check out the start of my build log here, the one in my signature is my old computer.

I cool my 9900k with a simple oc to 5 GHz with a 360aio and it works just fine, so I would reccoment to put the gpu on air and custom loop the cpu alone (when oc it will eat the 240 thick rad alone)

I'm doing two 360 rads for my 9900k and 2080 Ti.  Originally I had a single 360 AIO (H150i Pro) on just the 9900k and it was just sufficient to cool it when maxed out.  That being said, unless the task was CPU heavy, it barely got over 60C in gaming.  Like any recommendation, this is based on your workload mix and not absolute.

I would not go with any less than 360mm for a loop containing a 9900K and a RTX 2080, and even then I'd go with upper end radiators.

What case is it, impossible to do a 240mm and a 120mm?

Jay did a pretty high end build in the same case, he used an extention parts for it and managed to put 2 240 rads into it

i run an OC'd 8700k +1080ti on a 360 EK Phoenix and it cools that abolutely fine.


im sure you could get away with 240 in games (not synthetic loadtests) if you were ok with running the fans hard and loud. to do it "properly" youd probably want 360 min
