About the processor does not have to lose many words you, it belongs to the fastest thing to have at a moderate price. The boxed cooler is also good and quiet when one considers something: the applied thermal paste / pad is scrap. Reason: The heatsink has a copper core, which covers only about 80% of the heatspreader of the processor (it is slightly compared with the aluminum body before). Bring to the heat sink with no changes to the processor covers the Wärmeleitdingens (which after 1 day of operation is hard and brittle) approximately 2/3 of the copper surface, thus effectively is only about half of the possible processor surface as a transition point available: under load is the temperature over 90 ° high (no, that's not tolerable, although other reviewers disagree!) Solution: paste applied scrape covering CPU (heatspreader) thin with thermal compound - but not too thin because of the slightly protruding copper body, we also want to use the aluminum part of the heat sink as a transition point! Hold down the heatsink carefully and lock, avoid air bubbles if possible. With this solution, the CPU, regardless of load only about 70 ° at 30 ° ambient temperature, still no great shakes, this cooler but acceptable. 20 ° less heat are years in semiconductors in terms of durability ...
