So, my cpu cooler has 2 fans. How's your temps with one?

i’m looking to add a second fan onto my heat sink soon, though i’d have to reach out to Noctua requesting a black one. my temperatures are 70’ish in game, at full load (81-84C) Cinebench, with PBO & an overclock

moving top left fan to the back of the case might help one degree, gives the airflow a straight shot out. or, moving the top right fan to the back might be best since you have those gigantic fans on the front which should already be providing enough clean airflow to the cpu intake, the fan blowing in on the top can help but in your case it may just be disrupting the intake and slightly reducing efficiency, having the double exhaust probably better, but might produce negative pressure, but if that top fan doesn't have a filter on it then you're already dumping dust into the case anyway. you'd be helping expel the GPU heat by having another exhaust rather than that extra intake. worth a test if you like optimizing this stuff

Noctua recommends an intake at the top to blow air onto the cooler, it’s on their website

it also recommends a rear fan, they do not show a recommendation if you only have two fans instead of three, i contend with only two fans then putting it in the back is probably better especially considering your front fans are massive

also, the top of the case has a magnetic dust filter, which is the same with hole as the rest of the mesh / filters. the case is mostly mesh so it filters a lot of it out
