Alright, so as I have mentioned before, I am still using a plain vanilla case from before they even came in black. I have been running it without panels or fans and I finally decided to put it back together. Here it is in all its enemy-to-heat glory: Alright, so I am now planning on modding old faithful here. Right now she's got one 80MM exhaust fan and it hasn't done anything for temps. There IS a place for an intake fan at the bottom of the front, believe it or not, and that's where me needing wiring help comes in. (Don't worry, I've already thought of modding the cover plate with a grille for [better] flow) Check out the plug on this old case fan, probably as old or older than the case itself (next to the A64 system that the currently installed fan came from): WTF is that? Did they even have those plugs in ATX boards? It could also be an old power supply fan, from a busted power supply, like this 120MM fan that came off my old fried PSU: It's a sexy beast (albeit filthy as All Hell), but once again, THIS one only uses only TWO wires, which is the part that freaks me out, because I'm wondering if I can even make that work with a 3-plug connector. In case you're wondering, here is the donor of the modern style plug: Yeah, the one fan that is from back in the K7 days actually has the newer connector. I did briefly think about using it as my GPU HSF, but I'll be moving this 8600 in my non-intensive Linux box soon enough anyway. Now, I think I get the basics here, but correct me if I'm wrong. On the 80MM fan with the 3 plugs, the colors basically correspond, black, red, (neg, pos), and white would match the yellow. I'm pretty sure I could plug that in and it would work. (I actually had a tech once convert all my fans to molex when a power surge killed my on-board plugs, so I know it has to work, if I have the technique down). Now my question about the white, or yellow in new fans/molex connectors, is this a ground? I am wondering if I can get away with connecting the 120MM fan to a molex male that I have, but I would have to connect the red to the red, the black to the blacks, and just cap off the yellow? Thanks in advance for any help or advice!
