Air cooling to AIO

[Caleb paegelow]

So I have a fractal torrent (full size) case, and my cpu is the 13700k. im currently cooling it with a chromax black NH D 15, abd am wondering if its worth going to the corsair h170i AIO. i have a slight undervolt on my cpu and cinebench r23 runs max it out around 85C. i know the torrent is supposed to be able to fit the 420 mm AIO, but is it even worth the extra money? (it would be front mounted if i get the AIO).

Typically? No. 85C with no thermal throttling for Clock speeds you wont notice much of a difference. The 420MM would allow you to boost for a bit longer, but overall the pump will be the limiting factor, not the radiator size. 280/360 pretty much perform within error margin everything else being equal, with some additional headroom for noise. Bigger rads = Lower fan RPM typically, but with the 13700k and 13900k Being VERY hot chips ( as well as the 7000 AMD CPUS, but intel is twice the power) it can be better if you want some quiet. But More parts that can fail will be the downside as well as software.

Look at Most of Gamers Nexus videos on the 420 AIO's, theyve done two and there was minimal gain from the 360. The Longer boost is due to the fact of Heat soaking the loop, it will boost for a bit longer compared to a air cooler. Thats why you hear them say in the reviews they have to "Let the radiator get heat soaked" and it takes more time then a aircooler by a lot. NH-D15 was around 56 seconds before it was fully heat soaked, whereas the AIOs that were 360 were around 5-8 minutes on average. 

 

Rads fin density tends to be pretty identical over all the AIOS, only the ones that arent Asetek get slightly different. So generally the only thing that changes is the pump itself, and the impeller design. Its pretty much the exact same pump in the 280, 360 and 420 AIOS because its just cheaper to do it that way then to make a specific one for the bigger rads.

ur claiming that 420 not rly any diff from 360, cuz pump is the limit?

Its a mixture of things, all things being equal, yeah the pump will make a difference. Fans can also play a roll. If you Have a Custom loop and do 280 vs 360 vs 420, there will be some improvements for bigger rads. But there is a diminishing return, and the Cooling plate makes a difference, the Heatspreader itself whether or not its lapped, warped, the Thinness of the IHS to the die itself, Direct die cooling etc. Theres a lot of differences that can be accounted for, but if you do all them and then test rads, yeah putting a wimpy pump vs a D5 Pump will make a difference.

saying that dont go over 360 cuz the pump is the limit is  just  wrong. 

it is always diminishing return in pc building, bringing it up is like saying. u dont need to have fun in life ur going to die anyways.

The amount of dimin, is not even that big.

85c is fine and further lowering temps isn't going to improve performance.

Extra cooling can be useful if you need more thermal headroom for oc'ing.

If anything, just put some stronger fans on your cooler..
