mikeock Posted August 29, 2002 Posted August 29, 2002 Finally did the 7volt mod on all my fans in my case except for heatsink fan. Here is a pic of what was done Share this post Link to post Share on other sites More sharing options...
ShadowLord Posted August 29, 2002 Posted August 29, 2002 How well did that work for you. I was thinking that 7V would be to little. Ive been trying to get 9V I figured that would be better. thanks Share this post Link to post Share on other sites More sharing options...
Psywar Posted August 29, 2002 Posted August 29, 2002 See now what u need to do is a 17volt fan mod.. you connect the yellow wire.. and the red wire.. that will give u 17volts.. and watch that fan spin faster then ever see see.. the things u can learn from me got a delta spinning and shooting out 84cfm.. at 12 volts.. up it to 17 volts see how much cfm it spits out then mwahahaha Share this post Link to post Share on other sites More sharing options...
posey Posted August 29, 2002 Posted August 29, 2002 you connect the yellow wire.. and the red wire.. that will give u 17volts.. and watch that fan spin faster then ever Sorry but, the yollow and red wires from the power supply give you 7v NOT 17v the yellow wire being 12v and the red wire being 5v.

d3bruts1d Posted August 29, 2002 Posted August 29, 2002 ya.. V1 - V2 = Vtotal Share this post Link to post Share on other sites More sharing options...

posey Posted August 29, 2002 Posted August 29, 2002 Ive been trying to get 9V I figured that would be better. If your not using the P4 connectors from your power supply. You can use the orange wire which is 3.3v and the yellow wire which is 12v. that would get you just under 9v Share this post Link to post Share on other sites More sharing options...
d3bruts1d Posted August 29, 2002 Posted August 29, 2002 Hadn't thought about that... may use that with my sunon fan to reduce the speed.... I cant stand to be in the same room with it for more than a few hours.. lol... Thinking about taking the PC off my desk and putting it on the floor... hopefully the carpet will help muffle some of the noise... that is assuming I don't cut off a toe...

YODA74 Posted August 29, 2002 Posted August 29, 2002 the normal supplied voltage for a case fan is 12 volts. If you can lower this voltage you can reduce the fan's noise. The problem with this is that computer PSU molex supplies either 12 volts or 5 volts. 5 volts being a bit too low to provide any decent air movement from the fan. How to get around this is to instead of using the 12v line and the 0v line to provide 12 volts, but use the 12v line and the 5v line to produce (12-5)=7v Use the picture below to see how the fan is re-wired. You've got me kind of confused here why would you lower the voltage it only reduces the speed and noise wouldn't be more efficiant to stay at 12v and get quiter fans??
