From the look of that picture it looks like you can remove the fan, or did you try that already? just removing the fan and not the whole heat sink. It kinda resembles a Pentium overdrive heat sink, those things usually had the CPU ID printed just under the fan.
Also I don't recommend trying to remove a heat sink that has been plastered on the CPU, more often then not the ceramic can end up getting a crack. It's a very delicate thing.
[EDIT]
Here is an example image of how an overdrive heat sink looks like under the fan. I'm not saying it will be the same, but it's worth a try before attempting to remove the whole thing 😀
