Thanks for the reply.

From your description I assume the fins are integral to the heatpipe and the threads for the retaining screws are in the walls of the block yes?

If this is indeed correct a simple "strap" type bracket shouldn't be hard to engineer, I'll look into it as an option.

The current setup is workable so I will weigh up whether the modification would be worth attempting.

Either that or start saving for the i7 upgrade which may require a secondary income at present pricing
