It looks like you just have the 25mm fans. Do they do a decent job of pushing air through that 60? Or did you have to adjust the fan curve higher compared to your old dual 30mm setup?
Sorry for the late reply Baka. Its been unusually hot the past two days, 77F in ohio in april when it was 42F the day before lol, so I wanted to be sure of things before I replied.
Temps are worse with this setup compared to my dual 30 rad setup. Putting on all the case panels definitely is contributing to this though, especially the tempered glass panel. I was running the dual 30 rad setup without any panels.
I have the fans set as exhaust, so theyre pulling air through the rad and they do a great job. The fin spacing on this alphacool nexxos rad is very wide so there isnt much restriction at all.
Im going to hook up some more external radiators in a seperate room, plus another D5 pump so im not concerned. If I was to run off of only the radiator inside the case, id have to get some Noctua industrial fans and another perforated side panel. I am running my 4090 overclocked as far as she'll go at 1.1 volts with the power limit wide open so if I were to undervolt and run at a more normal clock I would see acceptable temps with the setup as is.
I wish I would have tested the dual 30 rad setup with the side panels on so I could have a more definitive answer of which is better, one big radiator or two thinner radiators.
