Hey guys and gals ima try and make this quick. I have 3 intakes (2 front one bottom) and two exhaust (one rear and one top rear) currently in my case and theyre all the same stock fractal fan gp14 i think? I'm thinking maybe i should upgrade, my OC'd r9 390 runs about 70-75 under load, im going to xfire them soon so my ultimate question is will i likely need to go with stronger fans? These are quiet but they only run 1k rpms. Open to suggestions about fans and fan placements here!
