Bolt-on RAM/VRM sinks for 4850/4870?

They didn't believe most people would change the cooling. The only way I could conceive the card would be able to "sense" that the stock cooler was changed was through the 3-pin fan header. Obviously there is nothing else that would tell the card the cooler was not installed. Alot of emails went back and forth discussing which parts needed cooling and what the failure temperatures were, I thought that information was something that I should share now that I'm not even using an HD4870. That was a direct paste from the email I received though. I hope there isn't a bigger issue and these cards don't all start failing. Maybe I just got really unlucky with the two I had.

Anyways, I'm still hoping you put out a set of sinks for the GT200 series iandh ;) I've had to ghetto chop the 8800GTX mosfet sinks for my GTX 260.

Don't get the idea that I don't appreciate your contribution, keep it coming... :up:

It just sounds wierd. Is there any chance that english is not his primary language and there is some type of misunderstanding?

I talked to my boss about switching voltage regulators, and he said that it is normal to see a current spike before they fail. Other than that, the current draw should stay dead stable regardless of temp up to the failure point. If the VRM's were left uncooled with an aftermarket cooling solution for the GPU, it would be expected to see a spike in current draw followed by failure, as we've seen several times here.

Maybe that is what he is getting at.

Yeah, there has to be something here somebody is missing, I'm not sure who or what though.

i have your 8800gt sinks and they rock, they allow longevity for my mcw60 block. 1 thing though..

could you machine us a 120/140mm fan bracket that utilizes the pci cover bracket slots? It would also be cool if it was adjustable from side to side...

that would really help a lot of us using just sinks or your sinks in conjunction with a waterblock

would you foresee any problems with the 4870 1gb version? layout looks the same to me just wanted to get your thoughts.

I get mine tomorrow so I can check, but afaik the layout is identical with 2x density memory chips, so they should fit fine.

i installed them on my HIS 4870 1gb and the ram sinks do appear to be a bit off but not to a degree that it really matters i don't think.
