Thats about 350Watts extra for the cooling. I have never looked at anything to do with effiency so I dont know.
But thats close enough to half a ton AC I believe, Half a Ton AC takes about 500Watts theroitically.
But yeah keep that processor at -26 with 5.2 on all 8Cores is something....
Is it possible to see it runm OCCT for like 45mins or more...I would love to see how the temps change, which I dont think they should change much over time.
