OK, so decided to go with fat a** radiator Got cheaper Feser 120.2, which is exactly same size as I have space for rad in my Cube. Problem is that its thicker than Swiftech and now PSU in case will be very close to one of the rad's fan. 5mm gap actually between fan and PSU side. I have to ilustrate it As you can see, for one fan there is pretty much small space for sucking air. Getting into acount size of rad and lentgh of PSU (which is out on the back for 5cm, so from 16cm, ther is 11cm left insie the case) 11cm of PSU inside the case will cover about 3/4 of the fan, cause first ~3cm is a barbs section on rad. It will be about 8cm of fan length covered with PSU, well still leaving 5mm of space... Both fans will work in pushing air config. I think there is an option - I can swap fans on other side of the rad for pulling config, then rad will be close to PSU, but fans sucking air through the rad will have more power - is that correct? Or can I get away with original config - pulling, fan next to psu?
