Bluescreenofdeth.net has just posted a review of the Vantec CCK-6035D HSF. here's a snip:
"The CCK-6035D is Vantec's latest offering into the Copper cooler market. The CCK-6035D consists of a solid copper base with two banks of thin copper fins mounted on it - totaling 34 fins. The heatsink has an anodized aluminium surround, with only two sides of the heatsink open. The CCK-6035D uses a Delta 6,800 rpm 38 CFM fan, and comes complete with a 3 - 4pin adaptor to plug straight into your power supply. they've even included a chrome fan grill to prevent any amputated fingers. Also provided is a sachet of white thermal gloop; although I'd advise using somthing better than this such as Artic Silver II."
