Hey guys.. I'm thinking of removing the stock HSF on my Sapphire 7500 and re-attaching it with some AS3.. but i'm wondering, will it make much of a difference? I'm trying to up my 7500 as much as it can (because i'll be with it for a long while before I actually upgrade).. Right now, I'm running @ 320/220.. anymore than 320, i get artifacts.. anymore than 220 for the memory, i start getting errors as time goes by.. Also, I'll be cutting up some old heat-sinks to use for my ram.. will it help in any way? thanks.
