I will make this short.
I took my Accelero Twin Turbo off my old 4870 (Currently on sale) and decided to try it on my 4890.
The Twin Turbo fits with no problem.
Ram sinks, no problems there too.
VRM on the other hand, that's a slight problem. They are 5 of them and 2 of those are stupidly small. While the sinks do hold, i don't think that they are sufficiently cooled.
I ran Furmark for stress testing with both the stock heatsink and the Twin Turbo.
Stock fan: PASSED went up to 90 degrees with fan speed hovering around 50% (automatic)
Twin Turbo FAILED went up to 88 degrees with fan speed set @ 75% (manual) then LOCKED UP. Did not try fan at 100% btw.
I really think that the VRM's are not being cooled sufficiently resulting in overheating followed by complete lockup.
The Twin Turbo may keep the GPU running cooler and quieter but i don't think that it's really helping the rest of the card and the heat inside the case. I'm going to put the stock cooler back on with better thermal paste this time. The Twin Turbo is better for the 4870.
