I just want it on record that I think thermal paste is just about the messiest thing in existance. It's good at what it does, but it's also evil. Not even GoJo can get all of it off.

Or zip ties through the star loops and thermal paste between the PCB and the aluminum?
I think we used safety wire, but zip ties will work as well. Bolts would work fine as long as you torque them correctly(i.e. have someone that knows their bolts and doesn't have the desire to tighten till it cracks, back a quarter turn it).
