This is Sanyo Denki's highly sought after "9G1212H1011" 120mm x 38mm case fan. The "San Ace 120" pushes 99CFM of air at a modest noise rating of 39dBA. Although this is a great fan at full speed, what makes this fan truly desirable in the PC enthusiast community is its uncanny ability to under-volt. Pair this fan with a fan controller and watch it shine, these fans outperform the high speed Delta fans at lower speeds. Perfect for overclockers and for water cooling radiators with large fins, or for anyone that wants a deep fan that can be tuned down for a quiet environment. The Sany Denki 9G1212H1011 is typically sold with bare wire leads, but SVC.com is selling this with a 3-pin connector already on. Grab a couple of these bad boys and a fan speed controller and it's plug and play for massive, quiet cooling.
