There are adapters for some sockets, yeah. Usually they do it by having multiple screw holes in the mounting base (plate attached to the back of the mainboard), so wherever your socket puts 'em, they'll hit in the right spot. > > carried yet, though that doesn't seem right.

Lower dB and higher CFA... another consideration is whether it can help cool the various other hot things, like mosfets and RAM. I recall one that had a shroud that covered up some hot stuff and that wasn't so good for the whole. > KM> Busy is definitely warmer.

Initially appears to be 45 years but I can't say has Woah... used to have a couple of vintage fans like that, but got lost in the Great Northward Migration.

Yeah. I have some salvaged from power supplies, but would have to rewire 'em. > KM> If they're that much of a cooling problem I just leave the side > KM> panels off.

Almost touches the side panel. > issues, improper air flow, etc. The good news is the open side is I've found the airflow thing is mostly a myth. They talk a good line but when temperature is much lower with MY airflow than with THEIR airflow, and I see that over and over... well, I stopped worrying about it. I remember the top-end Dell someone gift me because persistent overheating caused chronic crashing, and it was borderline even with water cooling (which he didn't send with it, put it all back to stock). And everyone was all OH NOES you can't mess with their meticulously designed cooling, that would be bad! Erm, their meticulous design is overheating at idle, how much harm could I do?? So I ditched their stupid shroud, replaced the thoroughly useless fanless heatsink with a proper if generic heatsink-with-fan, added an intake fan, and its CPU temperature dropped 40F degrees. Yes, FORTY DEGREES. And it never crashed again (at least not until the capacitors failed). Same with leaving the side panels off. Then you don't need to worry about evacuating the hot air; it leaves all by itself. Same reason I like to have a top vent, to let it escape. > against the cabinet, so doesn't show, plus no accidental finger-poken. > I did put a 80 mm fan at the bottom-center of the open side to help move > air around. I'd leave the open side a fingerwidth away from the side of the cabinet, to let more hot air escape. > KM> Yeah, I need to get some more of those magnetic fan-cover filters > KM> for the intake fans.

Well, given it's where you can't stick your foot into it, I'd just leave enough room for circulation and not worry about it. Bullet ran with both sides off for years; only reason they're on now is cuz it's not running due to Rearranging Of Hardware. Bullet's southbridge likes to run at 220F, so the less between it and the open air, the better. Got a copper heatsink for that but so far have not quite figured out how to make it fit... might need a different one. þ RNET 2.10U: ILink: Techware BBS þ Hollywood, Ca þ www.techware2k.com --- QScan/PCB v1.20a / 01-0462 * Origin: ILink: CFBBS | cfbbs.no-ip.com | 856-933-7096 (454:1/1) .
