sensorium Posted April 22, 2009 Report Share Posted April 22, 2009 I've looked everywhere and I've had no luck. Performance PC's has orange in the 20mm size, but I want to avoid that due to noise issues. I have amber diffuse LED's and an amber Crystalfonz LCD for the control surface and I would like a fan to match. Can anyone help? Quote Link to comment Share on other sites More sharing options...
Smithy Posted April 22, 2009 Report Share Posted April 22, 2009 this is proabably the most unhelpful post ever, but one alternative could be replacing let say a blue one, with an amber coloured LED. Quote Link to comment Share on other sites More sharing options...
Wilba Posted April 23, 2009 Report Share Posted April 23, 2009 Noise is a factor of fan speed, not width. Just run the 40x40x20mm one with 5V and it should be OK. You could put a 7805 into V4 and use this as a separate 5V regulator to drop the unregulated 9V - this may reduce possible noise on the supply for the rest of the PCB, and thus reduce possible noise in the audio outputs. Connect J25:9V-11V to J74:1, then you can connect the fan to J74:2 and some other ground pin (preferably J25:GND). Maybe you can use a 7809 in V4 instead... probably better, as a 7805 might get pretty hot. Try your fan on the existing 5V and 9V supply pins, if it's not too noisy and doesn't introduce noise in the audio, then don't bother with this separate supply circuit.Remember though, the fan is just for looks. If you cut slots in the right side of the case, the warm air can escape and there's no heat buildup. Quote Link to comment Share on other sites More sharing options...
