wow, nice temps! in this configiration may I ask you to test also with raised bottom? don't know how much, everything not less than 1cm will be ok, I suppose
GPU temps?
Thanks!!
Tested lifting the case with some spare case feet, they’re just propped up temporarily:
Also wiped down the case to remove fingerprints...
In terms of thermals, I can’t really tell if there is a large enough improvement. 80-85c during Prime95 small FFT torture tests.
About 65 to 70c for productivity loads. Some throttling though — 3.8ghz to 5ghz.
In terms of GPU, with the AIO radiator fans set to intake, my 2080FE temperatures sits at about 78c (stock 50-60% fan speed) for Heaven tests. With a more aggressive fan curve (up to 80% fan speed), GPU temperatures comes down to 63c.
A note about performance of the Z390i heatsinks —I had to remove all of the “ornamental” motherboard heatsinks to fit the NH-L12. Since I didn’t overclock my 9900K with the L12, the VRMs were ok. I’ve done this before in other Asus ITX motherboards before, and they are usually ok. With the 9900K, the motherboard VRMs do get push a lot harder than my other build (8700K / Z370i).
With the 240mm AIO, if I leave the motherboard VRM heatsinks off, the motherboard would throttle non-stop. Fluctuating from 150w to 170w, and as a result, speed goes between 3.6ghz to 4.8ghz. It was a throttling mess. If I were to keep the AIO, I might reinstall the motherboard heatsinks, and find a good balance for power / temps / speed.
Another note on the Enermax Liqfusion. The backplate insulating foam is not great. It has degraded over two to three rebuilds, and would short out some of the rear motherboard components. It was extremely frustrating to troubleshoot, as I had to tear down the whole rig multiple times to spot this problem.
