What would the options be for a better prformance fan if noise was not a concern?
From purely a cooling standpoint, four stock H100 fans in push-pull would be superior.
I replaced my H100 fans (it only comes with 2) with four noiseblockers in push-pull config.
The 4 noiseblockers are quieter than the 2 stock fans but it also cost me ~$120 for those 4 fans
(which is why I said cost and performance in my post)
Taking a $120 H100 and turning it into a $250 H100 with expensive fans and so on is silly to the extreme.
I did it just to see what it would take, but anyone who really wants a $250 watercooling solution should just get a legit watercooling setup IMO.
