If you own a Sanyo Denki 120mm fan... whatever you do... do not accidentally put your finger in there - you will bleed!
I was at work, testing it out... and my pinky slipped in here... it split the skin open and hit with such force that there was blood spray on the floor. Just a warning....
This is also a public service announcement for how crazy fast and strong those fans are.
Now with a serious question, is there anyway I can convert one of those 3 prong fan plugs, into a 4 prong power plug... or just simply extend it, the wire is too short to plug into my fan controller.
