Deepcool today announced a refresh of their previously-released GAMMAXX X 400 tower cooler. The new version will see improved cooling performance, due in no small part to the new dual-fan support. DIMM clearance has also been revisited, so as to prevent the new GAMMAXX 400 EX from interfering with your DIMM slot installation. The number of fins has been increased to 56, which means an extra 20% heat dissipation are that can be served by the increased airflow from the dual-fan configuration. A 4x 6 mm sintered copper heat pipe design (sintered as in, produced via pressure or temperatures that don't liquefy the copper) with Direct Touch technology should accelerate heat transfer form the CPU heatsink through to the cooling fins.

This is kind of a weighty design, coming in at 930 g for a cooling solution. Dimensions stand at 129 mm width, 103 mm thickness, and 157.5 mm height. It's expected the GAMMAXX 400 EX will be available around the $39 mark. For that pricing, it includes 2x TF120 high performance fans.
