There are two main reasons for changing the default cooler that ships with central processing units: the need for better cooling performance or the inadequacy of the size.
The former reason is what usually prompts gamers to call on the services of cooling hardware designers.
The latter case can arise when people want to make a small home-theater personal computer but the cooler is too tall for the case.
Cooler makers have an easy solution: low profile coolers. Akasa has just launched one in fact.
Called Nero LX (codename AK-CC4011EP01), it measures 120 (W) x 120 (D) x 59 (H) mm / 4.72 x 4.72 x 1.96 inches and weighs 298 grams / 0.65 pounds.
Four direct contact copper heatpipes take the heat from the CPU to the fin array, which is then cooled by a PWM fan of 120 mm in diameter and a rotary speed of 600 to 1900 RPM (11.50 - 31.50 dBA sound output).
Akasa's Nero LS works with both Intel LGA chips (775/1155/1156/1366) and AMD CPUs/APUs (AM2/AM2+/AM3/FM1). No price is known, unfortunately.
