Arctic today announced the Freezer 13 X Series CPU air coolers, including the A13X, A13X CO, i13X, and i13X CO. Smaller, quieter, more energy-efficient and powerful: The Freezer 13 X series, successor to the Freezer 13, combine a compact and advanced heat sink design, with different versions being developed for different areas of application:

Offset direct touch heatpipes in conjunction with a pressure-optimised 92 mm fan ensure optimal heat dissipation - despite the comparatively small dimensions and an installation height of only 137 mm. All coolers of the Freezer 13 X series are supplied with pre-applied ARCTIC MX-2 thermal compound and have a simple assembly system.
 
The Freezer 13 X series is available now on the market and at Amazon, starting at a MSRP of £ 25.33. 
 
What an excellent price for a CPU air cooler.
