5 & 12 VDC cooling fans for the V6 in particular. From past experience with these fans I have found that they can be a little noisy when moving air over a closely mounted surface. To quiet these things down I install a silicon rectifier diode in series with one of the leads The approx. .7v drop will usually slow it down so that it'l be less annoying.
