Arctic Cooling Accelero L2 Pro on GTS250

Not entirely sure what you mean, but it looks like it comes with a 4 plug Molex connector, which would attack to the similar plug coming directly from the PSU. Then there is a 7V and a 12V plug coming out of that, and those are the ones you plug into the fan. The 7V will just be a slower speed than 12V - 12V is full speed. Pick the one you like based on noise levels (although make sure to check temperatures after in either case).

Thanks,
Shouldn't one also plug into the card as well though?

Nope. Normaly the stock cooler fan would be controlled by the card, but this aftermarket one is strictly going to run off the PSU 12V or 7V.

Couldn't you cut the end off leaving about 1 inch of wire from the old fan? Then cut the end off the new fan. Then wire the old connector on the new fan? That is if the fans are the same size, that way your card will controll the new fan.

I am a electrican and low voltage tech. This is just an Idea and I am not there so I can't see the fans to be sure it would work or not. As long as the wattage is the same you could do it.

The after market fan you bought. Was it stated as a replacement fan for that card? if not don't take any chances and forget what I said. You could end up really messing up your card.

Another Idea is expansion slot fan to plug into a slot next to the card. Here is a link to one.

I think the card's plug uses PWM control (3 wire) while the new fan is only a 2 wire. So it might not be able to control a 2 wire fan. I don't know the finer details.

Ya you are probaley right. He would have to know which wire is what. Like I said I am not there and I can't see his fan's.
