You need to get special VRam cooling accesories(they are different for each card although the stock ones they give you work for most cards) for your VRam when buying accelero XTREME. You probably didn't and that's why you had those issues, Nyt. That GPU cooler is amazing according to all the reviews i've read. I don't have time to link any benchmarks and tests right now but I will once I get back home.
i doubt that is the case as there is only one version of that cooler that works with the 5970 due to it being a dual gpu card, and i know it comes with all the proper heatsinks
Its not for VRAM (memory) its for VRM (voltage regulators that get very hot) .The VRM accesories dont come with the Accelero for single cards but they are included
for the dual cards. With the VRM heatsinks, it is still very hot. Without the VRM heatsinks they would almost instantaneously blow under load
The benchmarks and reviews show the GPU temperature
while I am talking about the VRM temperature
. GPU temps are good but many reviews cant show the VRM temps because you cant actually monitor them on some single cards.
And dont think this is an issue on dual gpu cards only, I have seen reports of VRM temps over 100C on Accelero's fitted to 5870's, 570's and even 7970's.
Just my 2C. Your fault if the VRM's blow under a high OC
