It will work but I need to order some other stuff and I was trying to keep it all on one order. I need to also get a white switch(I think I burnt out the LED), 2 Noctua 140mm and 2 Noctua 120mm fans. I may have to just bite the bullet and order them from separate locations.
A diagram would be great! Also is there a way to do it without the use of a relay?Originally Posted by Furball Zen;15344504
Oh, certainly, you flip the negative side instead of the positive side. Its a trick we used when installing car audio in certain vehicles for power antennas.
You use a relay (in this case, a reed relay) and use it to cut the ground when the HDD activity activates the positive.
Normally, you use a relay to route the positive side through it, you just do the opposite in this case. You hook up the negative side of the coil to one of the through put sides, and the neg side of the LED to the other. Then the positive side of the coil goes to the positive lead on the HDD indicator header. I can draw you a diagram in paint if you need it.
Want to add, that you need a N.C. (normally closed) relay for this, not a normally open which are the most common ones.
Alternatively, you can use a 5 pole relay and use the inside pole for this, is this diagram its pole 87. You would feed positive to pin 85 ONLY, then negative to 86 and 30, your negative output would be 87.
