I wanted fit as much power in this specific case and try to use it as my daily driver because there was something about the design that just works for me. However when I was building it, I went through 2 different small form factor cpu coolers; the Noctua L9I and the Cryorig c7. Neither of these could cool the 8086k properly, especially in this cramped case with no exhaust nor intake so I had to get a 180tdp Thermalright AXP-100 full copper, and with the included adaptor, I was able fit an A12x15 PWM on pull config due to it having no air at all with the power supply taking half of its surface area. With only 2mm of clearance, I wasn't able to use the fan I pulled from the L9i since it was creating a lot of turbulence thus producing an incredibly unpleasant high pitched noise over 1600rpm. The noise produced by the 120mm counterpart in this setup is bearable.
(I also bought two noctua 40mm ones later on, although I doubt they did anything at all.)
So after 3 days of trial and error, trying to make it as cool as possible when playing rainbow six siege, I was able to bring the cpu down from dangerously hot 96 degrees down to an "okay" at 78. 40-90% cpu load. Although it is still quite bad, I do think this is the best I could do for now since I'm working with the worst "case" scenario. Sorry for that terrible pun. I didn't even bother with stress tests because I already know what would happen.
Oh this is all at base clock with turbo boost at 4.3ghz by the way.
I might get a dancase and fit the asetek aio on it later on as I am not using the cpu to even close to its potential but I'm not going back to an ATX because those are gross. Pls don't hate me for saying this lol
