hahahaha is funny, I am not getting full performance as a Mac device, I am getting a full lot more extra performance!!!! The processor is always at 4.1ghz with all cores (base clock is 2.9ghz) one core 4.3ghz, no thermal throttling in cpu and gpu (like in a real mac Sadly). The apple macs don’t perform good, for the thermal problems ther perform bad (I tested in person is a sad reality), the only device that perform good with no thermal throttling is the new macpro (I already tested). for the aio water I don’t know yet, I just ordered the i9 and better motherboard, hope the next week I will get it, because of the covid-19 is getting more time, but I will use my Corsair 150i AIO, but with the Core i9 9900K i used a Corsair H60 (the new model) and It worked just fine with overclock at 5,1ghz (75/80 degress). But of course a better aio will help you a lot...
Don’t worry if the config Of your hackintosh Is right, it beats any posssible Apple mac that you can find on the market...
