Good cooler for 4890?

Like this but without the fan? The fan on your GPU cooler would presumably be blowing down and cooling the plate too?

Unfortuneally, this seems to be the only way to do it. What I dislike about this, is that I have the impression that heat gets transferred through the plate, from the VRMs to the memory chips, thus still keeping them hot and probably limits their overclock. I might be wrong ,though.

The mem chips don't get that hot anyway though. I think you'd run into the limits of the memory chips themselves before running into their thermal limit. PLUS...the 4870 isn't really mem bandwidth starved anyway right? I don't remember getting much in the way of fps increases by upping the mem frequency.

Yeah, I think I'm going to skip the cooler for now. I can get pretty good results with 1.375v with 975/1150, and keep the fan at 40-50%.

Hey all - I'll just hijack this old thread to ask a couple of related questions - I'm considering the Arctic Cooling accelero S1 rev2 and the Twin Turbo Pro to replace my (annoyingly loud) stock 4890 cooler.

1. I see some people reporting, that they can't control the fan speed of the TTP with catalyst, although that should be possible, evidently - any experiences with that?

2. I've seen reports that the VRM heat sinks are terrible, as also discussed above - which is why some people started recommending the Zalman ZH-RHS90 (which must've come out after the above comments?).. Any experiences with that?

3. Does the TTP need separate power for its fans, as in separate from the power supplied to the graphics card? I suspect this is a really stupid question, but I'm not really used to messing about with my PSU, and am worried that I might find it difficult. (The installation guides I've seen always seem to skip this point by just mentioning the 7V/12V adapter - which makes me think I'm missing something obvious)

Thanks in advance!
