Hey, I am a DJ and i have some lighting equipment that has a busted fan. However, the fan is a 92mm and i think i have found a good replacement. However, I only have a red and a black wire to connect to. So, I have found this fan, http://www.newegg.com/Product/Produc...82E16811999617
which looks like its pretty powerful and should be able to cool the unit, but it has a stray yellow wire. Do i actually need to hook that wire to anything, or can i just cut it off. What about this fan, http://www.newegg.com/Product/Produc...82E16811999028
In the pictures, it only shows a red and a black coming from the fan, but on the 4pin connector thing there is a small yellowwire.If i get that one, and cut off the 4 pin and solder red and black, would it still work?
