I just got this hd5850 a couple of days ago. The stock gpu cooler looks a bit small for this card. What do you guys think, should i buy an aftermarket one?
Will dropping the temps extend the life of the video card?
That's a non reference cooler already. It has what looks like to be a few copper heatpipes leading to either an aluminum or copper heat sink and a fan. The only problem with this cooler that some don't like is that it's spitting the heat inside the case instead of outside the case as the reference ATI cooler does.
Dropping the temperatures on your video card will ensure greater stability over the life of the card, yes. It can also allow for safe overclocking for increased performance too.
Wa1 i get 40c on normal computer use/internet surfing and it hits 67-70c when gaming (alien vs predator).
My research turned out that 67c is normal for a video card but i was wondering if its worth it spending like $60 on a new heatsink in order to drop the temp a few degrees and the video card life.
