Hello, I've got a Gateway machine. It's a Pentium III 600. I also have 384MB RAM and an Anihilator 2 GTS video card. I don't think I'm having any heat problems but I'd like to get some more fans/heat sinks/whatever to cool it down a bit and maybe get some better performance. Now I've done a lot of stuff with this machine and I've messed with computers a lot but I've never really done anything with fans or any of that so I'm sort of clueless here. I wouldn't know what to buy or which ones would work in my machine, or if it even matters. Just looking for some general advise. I saw these fans that attach to your hard drive at CompUSA that looked like it just took up another 5.25" drive space which I have. Are these a good start? I would like to get some good air flow through the box and maybe a bigger heat sink on the processor. Help me out guys! Does the type of motherboard make a difference? If you need any more info about my machine setup just let me know. Thanks!
