When you want to get the most performance out of your gaming rig, you'll naturally want to try and overclock it. However, you have to deal with the excess heat put off by your CPU (or whatever component you're overclocking). One option is to get a bigger heatsink and throw in some extra fans, which while it may do the trick, it can make your computer sound like a small hurricane. That's when you should start thinking about a liquid cooling system. They'll keep your computer running ice cold without creating all of that noise.
Of course if you've never actually set up a liquid cooling system, it probably looks a bit overwhelming. There are several different components you'll need to carefully assemble, not to mention the cost of actually acquiring said parts. To the novice, it can seem like much more work than it's worth. That's why this PURE from CoolIT can be quite appealing. It's a self-contained liquid cooling system that is supposed to be simple install. I've had a chance to test one out, and I've shot a video of the installation process. Hit the jump to see the results.
