When it comes to enhancing PC performance, no tweak or mod is too small to consider. Asetek is well-known for their dabbling in liquid cooling, and the company announced earlier in the year that they would soon be releasing a CPU cooler. Now, they've assembled a video to showcase the liquid cooled PNY XLR8 GTX prototype, and it's looking mighty impressive. You may wonder if your GPU needs a cooler; if that's you, it probably doesn't. But if you're the kind of person who can't stop overclocking, well, you know you're already licking your chops. Have a look at the video if you're okay with a tease -- the latest still shows this on track for shipment "later this year" at an undisclosed price.
