I've already placed arctic silver on there. The problem is I need an active cooling solution; i.e. something with a fan. I just can't seem to locate a good solution for this given the the BPPC's non-standard heat sink clips and no place to attach a fan.
That's why I'm asking here; I'm sure someone else on this site has solved this problem.
As i wrote the Thermal adhesive solution it works as a permanent glue and thermal paste not only thermal paste, the heatsink will stick on the CPU without anything needed to attatch it, so no clips etc needed it will be on there. Ive used it on loads of things from high end 600$ GFX cards to Chipset.
So any heatsink in the right size will do and any 40mm fan on that and you are set

The fan can be mounted with screws on mostly any heatsink.
Finding a heatsink is not hard, get one of an old VGA card that is bigger then the CPU then just saw of the excess metal to fit and put a fan on there.
If you want to save space I guess you could use revoltecs old chipset cooler (it was for GFX-cards when it was made later rebranded for chipset)

Ive bought a few of those kits (they include a few passive heatsinks also) for things and I guess the all in one fan solution with Artic Adhesive would be good enough (just saw of the mounting holes).
PS: A tip you could use really really fine sandpaper on the underside of the Revoltec cooler to get a better contact area.
Edit: For better preformance, the Akasa AK-210 chipset cooler is all in one if you don't want to mount the fan yourself, it will be more effective but thicker.
Also you will have to cut the LED wires to get rid of that awful light. This kit cost less then 5$...

So any heatsink solutions together with the Artic Silver Thermal adhesive will work fine and you don't have to worry about mounting it.
Also it's better to apply the Thermal adhesive on the heatsink to minimize the chance of getting the stuff on any pins.
Last tip, let the thermal adhesive harden for at least 5 hours and lay flat before starting the system.
Edit2: Also I write it's permanent, as artic states it is and it is but you can pry it off carefully without destroying anything with a thin razorblade and patience and clean it of with acetone if you by any reason would want to remove the heatsink in the future.
I am currently using Artics thermal adhesive on my Raspberry PI with a tiny custom made heatsink i made and a 20mm fan to keep it cool when I have overclocked it a lot over it's limits with quite high voltage way of spec to keep it cool enough and I have removed the heatsinks a few times since I have built new better heatsinks over time. SO now it has a 20x20mm heatsink with the 20mm fan. Fit's perfectly without touching anything else on the board and power to the fan is supplied from the GPIO pins.
