Then I also had to make a new retention bracket and don't laugh at it too much since it does look pretty bad but you don't see it anyways. I did use a sawzall and a bench grinder to make the bracket and there not really made for finish work.
So far it does seem like the vrms are staying cooler than with the stock cooler and quite a bit better than the enzos. Anyways here is some pics.
Edit: I just did some testing and apparently those aluminum sinks on the ram didn't do as good of a job as I thought. I was just playing around with GPUTool and with the aluminum sinks anything over 1225mhz on the ram would cause artifacting almost right away. I just ran GPUTool with 1268mhz on the memory for a few minutes with no errors. I would need to do more testing to see if thats truly stable but definitely an improvement in cooling on the ram.
That looks fantastic! Great job
The custom retention bracket you made is excellent! Nicely bolted on, too. So you were able to grind away enough from the Uni-Sink to clear the heatpipes. That's ideal as you were then able to use all of the rest of the Uni-Sink.
Doesn't the card look so much better installed now, with the stock black backplate attached? And no more bowing, the Uni-Sink and backplate keep it nice and straight.
Testing time! You did get much better ram cooling, that's quite a jump in the clock speeds. The Uni-Sink and backplate are much beefier than the aluminum sinks and do seem to be dissipating more heat. As I also found, the Enzos didn't work that great on the vrm's, nice to have that big sink attached to them now.
Very impressive, you have a real cool-running 280 now. I don't think anyone could do any better than that on air cooling. What fan are you using on it? I strapped two 120mm Skythes together and had to strap them to the heatsink for full coverage, when I first did mine. But you might be fine with one fan mounted normally.
You da man
