Liquid cooling isn't for everyone. Self-contained kits have certainly made liquid cooling accessible to a new audience, but if the idea of running water through your system still gives you the willies, or if you just don't want to pay the premium attached to such cooling solutions, you're in luck. Air cooling is still vogue, and affordable! Just check out today's top deal for a Zalman CNPS10X Optima 120mm Fluid Shield Bearing Shark's Fin Blade CPU Cooler for $30 with free shipping (normally $35; additional $20 mail-in-rebate). It has aluminum fins, copper heatpipes, and compatibility with a wide range of sockets.
