Hi, I have an NZXT Vulcan Case, running an i5-3470, a 7770 in the first slot, 2x4GB of Gskill Ripjaws X, and an Asrock H77 mobo.
The stock HSF keeps my CPU very cool (45C in TF2, 50C in prime95), but its also incredibly loud and annoying. I'm looking for a good replacement, but I'm having a hard time finding a compatible cooler. The stock cooler is 90mm wide, and I have about 5mm of clearance from the edge of that to the RAM. The ram is also 42mm tall including the slot. My case only supports up to 135mm heatsinks. NZXT says that the case supports up to 170mm without the side fan. I have the 30mm thick side fan in, and it has rubber standoffs, which are a further couple of mm. So 135mm will be a tight fit.
For case cooling, I have the 200mm side fan, 2x120mm top exhausts, a 92mm back exhaust I have turned off, and a front 120mm intake.
Overall-lots of constraints:
-Provides 42mm clearance for ram
-Tower vs Downdraft- I don't know. Tower coolers can either be crosswise, and I can turn the 92mm exhaust back on, or they can be up down, using the top exhausts to draw air out. Downdraft coolers will be assisted by the massive side intake.
the logiysis 300keeps my phenom 42c at 100% for 2 hours ON all 6 cores idles at 21c , when I oc temps goes to 52c at 100% all cores 32c idle , never hear the fan
The fan is dead silent , It did not get these temps until I changed the factory paste , with factory paste temps were 5-8c higher .
It fits the case 120 x 120 x 25 mm with 120mm fan that has a cone surround that directs the air from the fan onto the 92mm cooler tower , a great design that works very well .
