Hey guys, I have a 2x120mm fan combo blowing on my heatercore. Problem #1, they are 115v fans, problem #2, they are BEYOND loud. Can anyone help me find the right rheostat so that the I could drop the voltage to say around 50v to one extreme, and 115v at the other. I assume someone around here can help me, you guys/girls are all geniuses. thanks for everyone's help in advance.
