According to Mr. Vinay Shetty, Product Manager, Component Business, Asus India, "With the increased power of the GeForce 8800GTX graphics processor, comes an increasing need for good cooling. A GeForce 8800GTX video card with stock cooling can reach temperatures around 80C at full load, something that isn’t ideal in the long run, especially if you want to overclock the GPU. Asus has chosen another route when it comes to finding a good cooling solution for an overclocked card. The Asus EN8800GTX AquaTank has combined an 8800GTX video card with a Water cooling device. So sit back and enjoy the gaming performance you've dreamed about."
Pre-sorting and stringent high quality checks on boards ensure that the EN8800GTX AquaTank/HTDP/768M can bear higher clock speeds. Add in new sets of overclocked configurations that are stable yet surpass conventional settings, and users can enjoy up to 11% faster graphics performance when compared to the already cutting-edge standard of GF8800GTX graphic cards.
The EN8800GTX AquaTank/HTDP/768M is equipped with the latest AquaTank all-in-one watercooled module - allowing the GPU to run at temperatures 12°C lower than the reference thermal module design. Additionally, the module fits perfectly into standard PCI slots inside the chassis that saves precious PC interior space - unlike conventional external water cooling solutions.
that's the dumbest looking thing I've ever seen.
