Cooling solutions OEM Akasa's newest offering is the AK-968 X4 CPU cooler. This value offering is designed to oust your stock CPU cooler for better performance at a low price. Measuring 135 (H) x 109 (W) x 90 (D) mm, and weighing 458 g, the AK-968 X4 resembles similar coolers in its category such as the Arctic Freezer 7 Pro. Its design involves a copper base plate from which three u-shaped copper heatpipes pass, conveying heat to an aluminum fin array, which is actively cooled by a 92 mm PWM-controlled fan that spins at speeds between 600 ~ 2500 rpm pushing up to 47.7 CFM of air, with a noise output of 17.0 ~ 29.5 dBA. It supports all current desktop CPU sockets, including Intel LGA-1366, LGA-1156, LGA-775, AMD s939, and AM3/AM2/AM2+. It is currently listed for £20 at a popular British etailer.
