The HSF features a kinda odd looking 92mm fan which should be very silent and deliver good cooling performance too as OCZ claims the Vanquisher can dissipate up to 200W:
The OCZ Vanquisher aggressively cools your CPU thanks to a pure copper base plate and three copper heat pipes that rapidly transfer heat away from the processor up to the dense, aluminum fin array where the thermal load is quickly dissipated by the included 92mm fan. The efficient heatpipe design moves so much heat that the fin array is able to transfer up to 200 Watts. The Vanquisher also utilizes a unique low speed fan mounted with rubber connectors to effectively decrease vibration and noise, ensuring minimal distractions at your workstation.“The performance of OCZ Vanquisher is not compromised due to its compact size,” states Jacky Huang, VP of Product Management, OCZ Technology. “Instead, it reduces the CPU temperature more effectively than many larger coolers in the market. As a bonus, its compact form factor allows it to fit in even most crowded environments and cases.”
The heatsink looks a bit like the Arctic Cooling Freezer 7 Pro but it's a bit bigger, the Vanquisher measures 72 x 110 x 134 mm. It's compatible with AMD's Socket 754/939/AM2 and Intel's LGA775.
