Alpenföhn K2 Dual Tower CPU Cooler Review

We decided to compare the Alpenföhn K2 against 10 other CPU coolers from a variety of price ranges that we have previously had experience with.

Testing method:

• Stable recorded CPU temperatures from a 15 minute idle test
• Stable recorded CPU temperatures from a 15 minute load test
• The cooler’s fans are set at 100% speed unless otherwise stated
• All tests are repeated to check the consistency and reliability of the results
• Delta temperatures are used in the charts to provide more accurate results
• Maximum recorded noise output at 100% fan speed
• The supplied thermal paste is always used to make the results a fair interpretation of the cooler’s stock performance
• The temperature threshold we set before calling the test a fail is 65^oC above ambient but if the cooler manages to complete more than 75% of the test before rising above the 65^oC delta mark, we allow it to complete the test, provided it is capable
• A +/- 1 degree Celsius margin of error is incorporated by our CPU/GPU temperature recording method
• A +/- 0.1 degree Celsius margin of error is incorporated by our ambient temperature recording method

Test system:

• MSI P67A-GD65
• Intel Core i7 2600K
• 4GB DDR3 1600MHz
