I'm rebuilding a case w/ an "ultimate air cooling system" sort of mentality, and have a secondary ps to handle all the fans. It's an old AT style, about 230W. My origanal worry was that it seemed to spike when it shut off -- the fan would "rev". Then I tested it w/ a voltmeter, so I wouldn't waste your time. I found that w/ a 92mm Delta, it would spike from 10.1v to about 10.5v (it's a cheap voltmeter and doesn't refresh very quickly, so it could be more). This doesn't seem to be a problem, since the Delta's are rated at better than 13v. But it's at 10v?! I tested a BIG Rotron, and it dropped to ~8.6v. W/ all the fans hooked up, I'd get like 2-3v's at best! (Unqualified estimate)
Now, I WAS planning to do a baybus type thing w/ the 7v mod, but it's clear that this ps isn't capable of supporting my insane need for more fans. I do have a 300w AT, but I've already butchered this ps. I don't want to just throw it away. So, any ideas on how I can use it? I thought about using two ps's, but I don't want to have two of those switches to deal w/. Can I put them both on one switch (I'm going to Radio Shack in about an hour, hint hint)? Can I modify the pcb itself by soldering or unsoldering things? I'll get more info on the fans and ps's if you need 'em. Thanks a lot for reading all the way to the end of the post!
