Summary: As a stock fan it does the job under normal conditions, but like another user review stated, it probably is too small for overclocked CPUs or if you run your system with a constant heavy load. My current fan has been working perfectly for over 2 years, just got this one as a spare. All fans will fail at some point.
Summary: needed to get a new cooling fan for an older desktop machine and this one was listed at a great price. Received fan, installed and it was very quiet. works great and performs the job. Would not recommend for a heavy user, or overclocked processor since it is single speed, and small heatsink, but it works well on an every day processing machine.
