Go with Gentle Typohons, they perform very good in almost all situations, really good fans, and less expensive than noctua and noiseblocker. The only downside why im not with them atm, is i wanted PWM fans, i really wished Scythe were to release a couple of PWM GTs, maybe 150-1450rpm and 600-2150rpm, those two fan would allow almost any config possible.
Now on your case, to replace a PSU fan, the GT seems a even better choice, a lot of fans dont like horizontal placement mainly because of how sleeve bearing are desing, in the case of the GT, they use real ball bearings, so they should perform well even on horizontal placement.
What you do need to decide is what rpm version you want, both seem viable, 1850/2150, up to you, i wouldnt go any lower or higher than that.Edited by Abula - 10/25/13 at 6:40pm
