Hi
My computer runs at normal use at 50 CPU and 37 Case. When playing Doom3 it goes up to CPU 75. I put a small fan against the exterior side of the computer vent and it cooled it down to 59 CPU and 40 case when running Doom3. I have another fan (dumpster diving) which is Nidec TD350dc (40cfm) brand new. It has 3 wires (yellow, black and red) ..... How do I connect it to my existing setup in the computer. Mounting the fan isn't a problem but the wiring isn't clear.

i think there are socket for this type of fans in your motherboard

i got 1 in my board

It sounds like a normal 3pin fan connector to me. They usually connect to the motherboard, if the motherboard has the corresponding port. My motherboard has 4 of these, and older computers usually have at least 1-2.

If your board doesn't have the connection, they make molex(4pin power off the psu) to 3pin fan power adapters, that should be cheap.

Thanks

I never used the fan because of the loose wires ends. By the time I found and put the connector on, it was easier to pick up a mod mutant fan and a 60 fan from the surplus store and install them. I found my motherboard diagram and it had 2 connections open on it. One for the front fan and another for the back fan....that made my life easier. Although I had to cut out part of the back housing to install the fan (60)..I don't like all the fins that were in the case. The side panel had a port from the manufacturer so that was real easy to install the mutant fan. Should I have left the port in and put the fan into the port or was removing the port tube ok? I have to run Doom3 again to see how the temps of the cpu compare now. If all else fails the blue flashing Mod Mutant lite fan looks cool anyways.
