Hi folks, This is my first post. here is the situation:I just rebuilt my HP with a Celeron 340 into another case, It has 2Gigs of RAM, an 8400GS. I am running a duel boot with XP and Vista. I have added a 350 Watt PSU. I play games pretty good with it, even Left 4 dead runs pretty well, My problem is keeping the thing cool. I ran across some fans that I salvaged out of an old Digital Server 7000. I aquired it free through craigslist. The thing was instorage for 5 years and had a family of mice that took up residence on the motherboard. so the machine itself was useless. so anyway, I want to cut 3 nice holes out of the case panel and mount these fans into it. No of course, I am planning to power these things from an external source. The fan specs are as follows. Nidec BETA V. TA450DC. They are 12V DC .49AMP. Give me an idea on how I can wire these up to a 12V Power supply. I also have a power switch from an old blown 140W PSU that I can use to turn them on. I just need to know how to wire these things. I have a huge box of power supplies from old nintendo power supplies, and phone ones, and battery chargers, way too many different ones to list. I love to tinker and modify, I dont throw things like that away, for reasons like this!!
