My sapphire 4870 is in need of upgrading from the stock heatsink. I dont plan on upgrading my GPU for awhile and i want this one to last, as it has been treating me well. Its pretty much a second heater for my room, too. Well summers hitting it soon and my load temps in the hot noon are hitting the high 80s, possibly low 90's. Im not really sure what heatsinks are out there and whats really compatible. Doesnt really need to have a fan included, i can just strap on a couple 90mm ones or something on it. Budget <$50. I was looking at the ARCTIC COOLING Accelero S1 Rev.2 for the longest time, but its been really old so i want to know if there are any other newer heatsinks out there can do the job better, and still compatible.
