Tutorial: Make Case Fans Quieter Without Buying Anything! Well, here is my tutorial to make case fans quieter while still moving a decent amount of air, not a 5 volt mod, that reduces air flow too much in my opinion, 7 volts is perfect for making your fans quieter and still moving air, I will also include a guide for 5v if you want super-quiet. I also included pictures for a dual fan mod (Both 5 and 7 volt) First to move the pins from one hole to another, take some needle-nose pliers and grasp the pin push down with a moderate amount of force, and if you notice any metal pieces sticking out at the base holding it in, pinch those in and it will just pull out. Keep doing this until you have all the pins out that need to be moved, then just place them where they are supposed to be, then plug the molex's together and boot up, there will be a noticeable differance in sound without buying anything! For the dual fan mods, solder the wires together at any point, and electrical tape around the joint. I wouldn't suggest too many fans on one molex, but thats just my opinion. Here are some screen shots of what the finished product should look like. If you don't know how to solder, strip the wire at any point, then strip the other wire at the end, twist the wires together, and electrical tape over the joint. Single 7v Fan- Single 5v Fan- Dual 7v Fan- Dual 5v Fan- Written, made and tested my me! I notice a big difference in sound! Thanks for the move to tutorials!
