Ive had my pc about 2 months temps are gwnerally good never hits above 70 at max load. I have the standard meshify c case 1 intake 1 exhaust. However i want to add 2 new fans intake, then add the fan which came with the case as a top exhaust fan. So 2 rear exhausts which are 120mm stabdard case fans. Now the 2 intake should i get as 140mm fans or 3 120mm fans? If so what brand is recommended. Considering rgb but not fussed if its not. Or would you recommend a different fan set up? Thanks
