Noise is probably my biggest concern, since the more cooling needed the noisier it'll get. There's obviously going to be noise sacrifices just by virtue of running at 5ghz, but I'd still like it to be as quiet as possible while still staying within stable/safe temps
NH-D15 is comparable to an average AIO. See anandtech and tecchpower up reviews. Delidding is more important than an AIO.
I own the NH-D15, H100i GTX, and the EK Predator 360. They are all fairly comparable in their ability to cool assuming you are under 200 W TDP. Once you break 200W TDP you need a EK Predator 360 or custom loop. Anything sub 200W TDP they are all the same within 5ish C IIRC
most AIOs pumps are too low of volume to support more than 200W TDP. I ran tests on my H100i GTX and the water is 100% saturated at 200W TDP. It isn't the radiator, which is why AIOs that are 240/280/360 all do the same if they use those cheap low GPM pumps. You need the EK Predator 360 AIO or custom loop to pump water fast enough for 200+ W TDP
this user tested different fans and found out that its the pump that is the limiting factor not the rad or fans.
AIO would just allow you a more quiet set up but nothing major in terms of temps difference. The H100i GTX vs EK Predator 360 are within a few C difference on a 1650v3 guzzling 170+W TDP. You only need a fancy water ccooler if your using like threadripper or those huge HEDTs.Edited by HOPELESSLYFAITH - 10/21/17 at 5:04pm
