Need a good VGA cooler

[MenaceInc]

Basically, the 4850 I have in my computer has a cooler that only focuses on the GPU itself. This means that I can't overclock the memory at all, if I try and move it up even 10Mhz, the card craps out.

So what I need is a decent aftermarket cooler compatible with the 4850 that covers the GPU, VRAM and VRM. Preferably dualslot since I've nothing taken up the next space

Haven't looked into GPU coolers much myself but from what I recall this one received great reviews (although a little pricey): Newegg.com - ZALMAN VF1000 2 Ball VGA Cooler - VGA Cooling

Arctic Cooling is nice. I have nowhere near as fancy of a fan + heatsink as that, since I have a stock one on my 4670, but I get 52 Celsius on load with about a 10-15% overclock.

HR-03GT. Nothing even remotely comes close to the radiating power of that thing. You can run a 4890 without a fan and its still cooler than the stock heatsink. The HR-03GT comes with RAM-sinks.
