Starting from the front of the board, the Radeon X1650 PRO Ultimate's cooler doesn't look too imposing at all, with a simple heatsink sat over the GPU core, leaving the memory modules untouched and uncooled. Protruding from the right of that heatsink, you'll see a heatpipe which curves around to the rear of the board. Follow it around and you'll find the real meat of this cooler.

The rear of the Ultimate Edition is dominated by a simply massive heatsink, designed to dissipate the heat picked up from the front of the board which has been transferred to it via that heatpipe. With such a large cooling solution on the rear of the card, potential buyers should ensure that they have sufficient space above the PCI Express 16x slot for the board and cooler to sit. In my particular case, there was a very tight squeeze between this heatsink and the four-pin Molex connector used to provide power to the motherboard - Thankfully, it just about fitted into the required space, but other users may not be so lucky.
