ARCTIC Alpine 11 GT Rev.2

The extremely quiet ARCTIC Alpine 11 GT Rev. 2 is an affordable and perfectly silent replacement for Intel's noisy boxed CPU coolers. Its high-quality 80mm fan generates a maximum noise level of only 0.3 Sone, which is noticeably less than the 0.8 Sone in most energy-efficient models (such as the i7-3770S). It also offers more efficient heat removal from processor cores. However, this is not a tool for extreme clocking, as the maximum heat output is 75W. The pre-applied ARCTIC MX-2 thermal compound makes installation quick and easy.
