Wow, thank for quick feedback.
I will buy Noctua
May I also ask how should I turn fans (In or out) On web I found picture of the case and mark locations of fans.
Any idea how to cool 4 HDDs that are in 5.25 compartment where in orginal DVD writer was? Some kind of holder or something?
And last question, fan for power supply also need to be changed, it has only 2 wires. Should I use same 4 pin fan and connect it to MOBO or I can connect only + and - of new fan and connect it to wires of the old fan?
Power supply is Enermax Liberty Eco 620W.
