Do the arctic CPU coolers' "Cooling Capacity" value mean anything?

[monsieurpooh]

For example here http://www.arctic.ac/en/p/cooling/cpu/522/alpine-64-plus.html?c=2181

"Cooling capacity" 100w. Does that mean I'm not recommended to use it when overclocking a 125w CPU? What about a 95W CPU that needs to be overclocked which would probably make it go above 100W?

If the value actually means anything, how come it seems like no other manufacturers of CPU coolers bother mentioning such a value, and consumers don't seem to put a big priority on caring about the value? Does it really matter or is it just marketing?

That is a very small cooler for lower watt CPUs. You might run intro overheating issues. I would recommend getting a bigger cooler.
