Sapphire Liquid Cooled Radeon X1900 XTX TOXIC
 

Clock speeds aside, what makes this card unique is its cooling solution.
Instead of the reference air cooler that is so noisy noisy that I keep a set
of ear plugs in my desk drawer, Sapphire has chosen to use a self-contained
liquid cooling kit. As you can see, the actual cooler and the card are
separate units, so it will require a spare expansion slot to accommodate
this. The main graphics card has nothing but a waterblock on it, while the
cooling unit contains the reservoir, pump, copper radiator and cooling fan.
It is pre-filled, so you're ready to go straight out of the box. But if you
need to top up the coolant or even replace it – this is easily done
