It must be Vantec FCE-62540D. There is a survey about most popular heatsinks and I haven't seen almost anyone mentioning it. Why? According to the review on HardOCP here it perform great, just a degree more than the best heatsink. See this page for a nice comparison. And it's only $19.95 + $5 Priority Mail shipping from Inflow Direct! I really like the Priority Mail option as most of the country gets the heatsink in two days instead of waiting up to seven days via UPS. And the shipping is cheaper via USPS too. Lastly, it's not as loud as FOP38 and the clip is the best I've ever seen. Really easy to put on. I bought it and love it. A great cooler for a great price, I'm surprised more people aren't using it. Any opinions?
