IDK why people are knocking OP for losing the original coolers. You couldn't sell me a 480 with stock cooler for over $100. There is simply no situation in which a stock cooler is better than the aftermarket cooler:
A) One stock 480 just burns to death under the burden of its own heat. Never mind having a CPU in the case, or a second 480
B) You need three slots clear even with the original cooler. Sandwiching it between any other cards causes it to overheat.
C) If you don't have enough case ventilation to deal with the impeller cooler blowing heat back into the case, the crappy blower cooler will still push a lot of heat into the case anyway; you're still screwed.
D) Overclocking a stock 480 is not possible even when you have a bunch of slots clear, good ventilation, and just one GPU. Only an aftermarket cooler will release the 480 from it's thermal burden enough to overlclock.
I would snap up the both of them if my power supply and electric bill could handle it D:
If you live somewhere with cheap electricity, and have an 850W PSU, OP is like an angel descending from heaven, offering you a chance to frolic in a meadow of kittens with him.
Bump for good deal.
