Yep, the Blue Orb is about the best video card coolers made, in my humble opinion. I put a 40mm fan on the GPU heatsink of my Hercules MX card for a while. Then I replaced the fan and heatsink with the Blue Orb cooler. It definitely made a positive difference. I was able to run the core 10 MHz higher with the Blorb compared to straight out of the box with no mods. I'm not sure what Buzzardsnake is talking about...made the casing warmer...but it does help if you put one of those slot fans next to your video card to exhaust the hot air away from the slots.
