Akasa's Venom Nano heatsink stands 150mm tall, weighs 560 grams and installs onto AMD socket AM2/AM3 and Intel socket 775/1156/1366 processors. Off the cuff though, it seems a little 'modest' for Intel Core i7 use, dito for AMD Black Edition chips. The Venom Nano seems better suited to mainstream processors as it offers a good range of quiet operation and ease of installation. Retail price should be in the neighbourhood of $35 USD/CDN through the usual online heatsink vendors.
