I also use afterburner for my evga SC 560ti SLI setup....30% is as low as they will go but they use a single 92mm fan that are pretty dang quiet and seem well designed.... Until I game. I have a over aggressive Fan Profile and wear usb G930 headphones when gaming. Putting them on alone drowns 30db of noise up
I sometimes put them on just to drown out the TV noise when i am trying to get to sleep with the wife watching TV. They are very comfortable. I see so many people saying USB sound is a horrible experience. I have nothing but praise for these headphones, they sound fantastic, simulate surround very well for Movies and Games. Bass could be a bit better at high volumes...too loud and they will distort, they only have 40mm drivers...I wish they used 50mm!! Battery life is a good 10Hrs. Range is pretty dang good as they work throughout my whole house, even with the receiver in my upstairs bedroom they work in the basement of my 2 story single home. Plus it real easy to plug them into any of my PCs and use them quickly. Just wish they would work with my stand alone bluray player.
I also use Speedfan on all of my PC's to monitor temps and control my 2 HTPC chassis and cpu fans. My gaming rig i use a 5 channel fan controller.
My I3 2120 with a hd7750 setup has been in the closet up on a ledge with a small hole penetrating the wall to run all 7 of my cables to the computer and the TV box, Bluray player and TV power cable. My 55" tv is on a wall mount that sits flush to wall or will pull off wall 30" and adjusts in every imaginable way.
30" closer is awesome for movie night ..especially for 3D movies since it reaches my toes when we lay in bed. Very Immersive
