The Xigmatek AEGIR is a full-featured mainstream cooler and we are pleased to see it raising the high-end of the mainstream bar. The AEGIR  performed well throughout all of our tests, and could even handle the fully loaded i7 930 @ 4.0GHz while keeping it below 90c degrees. This is quite impressive performance, especially for a cooler in this price class, even without a 2nd fan attached. Analyzing the testing results reveals that the AEGIR still has more potential.
