Just built i7 case Silver Fortress, H50 put Apache fan to push as the top 180 Fan blow's directly onto rad, tube's+pump with external air nice and cool. Waiting for some screws l have ordered to come to mount 2nd Apache to pull them l will give you's some idea of temps also tidy cable's up. At present my PC idle temp across core's 38c to 42C + PC is in living room where it get's the sun all day. Had no prob,s while building, took bottom HD bay's out and added Silstone bay adapter 5.25>4x3.25 with Silverstone SSD mount 3.25>2x2.25(good craftsmem ship). Now bottom 180 fan is not restrictioned blow's directly onto bottom of GFX Card temp while idle temp at pressent 40c, load temp AV>62C, my PSU a Corsair HX850 fitted no prob's bottom of case, PSU fan is on top so it also pull's air out of the case, as the Fortress work's on positive air pressure, can't recommend this case enough great middi case it would be 100% quiet but you can just hear my DVD-RW spin up as the case is right next to me. Right where do l sign up for the Silver Frotress Owner's Club lol.
