Water-cool your PC

Zalman's kit includes a GPU waterblock that works with most recent graphics cards. Start by removing the card from the PC. (Detach your monitor, unscrew the card from the backplane, and unplug any power connector.) If the card has a fan, remove it by pinching its spring-mounting pins from below. Again, wipe off any thermal paste.

Zalman provides two threaded GPU-waterblock-mounting pillars. Install these using their included screws and washers, inserting the screws from the card's underside, through the fan-mounting holes.

Spread new thermal paste over the GPU as before, then lower the GPU waterblock onto the GPU with the hose outlets pointing toward the card's top edge. Place its mounting bracket across the top and screw it into the mounting pillars. (The bracket fits a groove on the waterblock.) Attach with two screws, tightening alternately. Once compressed, the waterblock shouldn't wiggle.

Before reinstalling the card, affix the provided adhesive-backed aluminum RAM heat sinks onto the card's RAM chips for added cooling. After you reinstall the card, remove the cover from a PCI slot and replace it with Zalman's cover, which has two holes to let tubing pass into the case.

Save your old fan and CPU-cooler parts. You may need them if your water cooler ever fails.
