Hi guys, I have a Thermalright MUX-120 with a single X-Silent 120mm fan (the one came with the cooler). I am thinking about adding a second fan to make the most out of the heatsink. However, I am having trouble finding an X-Silent 120mm here in Japan. So I was thinking about buying two identical fans for the Heatsink, and moving the X-Silent to the side-panel of the case to cool the video card which seems to be running a bit too hot. Can someone recommend me two fans to use on the heatsink. I want a very silent PC. The X-Silent is very queit. But there must be others which give better CFM for the same or lower RPM, right? X-Silent 120 is rated at 36CFM @ 19dBA. So basically anything that give 36CFM at a lower dBA or higher CFM at 19dBA would do. Thanks.
