Question Understanding heatsinks with multi-platform support? (LGA 1366 and LGA 115x)

Hi, computer noob here looking to make a first PC on a budget.

I have a CPU (Xeon X5570) that uses the LGA 1366 socket. I'm looking for a CPU fan.

There are some fans that say they support both LGA 1366 and 1151, but I thought that they were different sizes. Examples:
The former only lists 1366 in the title, and doesn't list it under supported sockets in the description. The latter says:

Universal Socket Compatibility with Easy Installation

Supports up to 130W Intel CPUs LGA20XX/LGA1366/LGA115X/LGA775

There are also several reviews that suggest that the latter does support LGA 1366.

Is the "Universal Socket Compatibility" a legitimate technology? Any idea how this works? If it does, can I trust either/both of these to work? I can't seem to contact the Ebay seller, they seem to not allow contacting them.

Actually, by searching around some more I found this cheaper (but smaller) CPU heat sink + fan ($10.96) with this lovely visual:

Thanks again to y'all for responding so quickly.
