Just info for people still thinking that best air coolers can compete with 360 AOI.
Short answer they can’t.
I’m in process building my new 9900k rig with GB Master Z390. It is still a open bench setup as I do not have case for it. For first testing I was using Cryorig R1 ultimate (no difference from D15). With this coller I was able to pass Realbench or Prime95 but without AVX. But anything with AVX was either crash or 110C.
Here is comparison between R1 and Corsair H150i pro.
I’ve found this info from
how to test it without full Prime95 AVX power virus. Do test with Prime95 one instance running on 14 cores without AVX and second Prime95 on 2 cores with AVX. Voltage was 1.320V with Turbo LLC. Vcore reading in Win was 1.256V under Prime.
With R1 temperature was just over 105C in 5 minutes but some workers would fail just little after that.
With H150i (from my Ryzen rig) I’ve passed one hour test with averages temp just below 90C.
After that I’ve even done full Prime95 AVX test (with added 0.02V) and after 15min I’ve stop due to high temperatures.
Just imagine putting both coolers in case. Air cooler using hot air in case will be even less efficient than AIO pulling cooler air from outside.
I think that my 9900k has horrible solder and it is hard to cool but that is not point.
But H150i which has extra slow 3x120mm fans running only up to 1500rpm is beating best air cooler with has 2x140mm fans running almost same rpm for 15C difference.
I was shocked with these results, as I was under impression that best air cooler is almost same as a 360 AIO. But they are not.
