Most computer fans will run from 5 volts upto 12. Some will not start at 5. They run slower, but do in fact run. I has been the basis of computer fan speed control for years(voltage control).

New PWM is now preferred by many users(and I would guess board makers as it should be more easy to implement.).

As long as the power source has the required current and starting voltage for a fan it will run, just not at full speed. I used to run some fans off a 10 volt external power supply.
 
Yeah it served me very well. I had this one specifically:

Great card.
 
I have a Radeon 7000 (circa..2002?), a Geforce4 Ti4800, 8800GT, 9600GT... I can't bring myself to toss them but I have no idea why. In their day they were all fairly expensive, especially the Geforce 4.

Did lose my Voodoo 3 at some point though. The QuakeIII nostalgia card.

Wonder if there will ever be a collectors market for obscure components, it seems unlikely but stranger things have happened I guess.
 
Tiny, that's the one I had too. That HIS cooler was outstanding; had it on a couple of their other cards as well. It was almost inaudible, but worked well.
Of the "sweet spot" cards I've owned, that was one of the best. I'd put my HD7870 in that category also, as it can pretty much run anything I'd like, on very agreeable settings.
 
The dual-fan ones? I don't know. The last HIS card I owned was a HD6790, and its single fan was definitely not quiet.
I can hear the HD7750 in Gypsy when I'm playing GW1 on it. My HD7870 stays quiet, but I've not stressed it lately.
 
I usually keep a [low-end] spare or two on hand, but my wife's HD6570 may be failing (her screen is lately divided and very colorful when her machine starts up, but is fine once Windows loads), and I've got another friend with a dead or dying PC I may try to fix. One will likely get the HD6850 that ColGeek so kindly sent me when I was fixing another non-gamer PC lately. It seemed such overkill that I ended up getting a HD6450 for it instead.
 
Well got the new 1300watt psu in and it works perfect no more shut downs while gaming or benchmarking. I dont think my old psu was bad because i could push the 1 780ti pretty far but when i tried to do both it dropped out. Maybe over amping and/or drawing to many watts for it? I dunno i just know the old worked great for 1 gpu but not for 2 and the new one supports both gpu's clocked at 1456mhz core and 3650mhz on the memory and it handled the benchmarking like a champ.
