LS Cable LSHS L500 and X500 CPU Coolers
 

I could come up with only 3 reasons why nickel is used on the bottom of heatpipe heatsinks: Nickel bonds very well and having a nickel bottom would protect the surface, prevent oxidation, and diffuse the heat. Since nickel retains heat longer, the heat will spread over a larger area which spreads it evenly across the heatpipes so you don't have just one or two doing all the work. I don't know if this is actually the case, but it makes sense to me (unfortunately, so does beer flavored ice cream).

They are underperform could be the result of concaved base as [M] has identified. I am surprised to hear this months later after we informed the manufacturer to correct the factory specs and quality Control.

Otherwise, this HSF has very good performance.

I gave them a heads up in their forums, good catch Lazyman
