Warning:
both these coolers have unusual & very firm fastening-clamps: that on the Golden Orb usually works very well indeed, so long as you have H/S grease between the CPU & cooler
& take the trouble to play with the thing first to see how it works.
The simple clamp on the Molex is ergonomically well-designed; but is so designed that the entire clamping force – while fitting – comes down at one point of the small circular
base against one edge of the exposed silicon FC-PGA die: though aware of this beforehand, & very careful with the fitting process, I managed to crack a corner off a highly prized CPU.
This corner-cracking has been held to potentially lead to further stress-cracks under thermal load, then to catastrophic failure of FC-PGA’s.
Be extremely careful when fitting any cooler with a high-force clip to a FC-PGA – ideally obtain & fit a CPU-spacer [a copper or alloy shim with a hole in it for the die to
poke through] before installing such a cooler – the shim gives something solid for an edge of the cooler-base to bear on while fitting, rather than the edge of the die.
Cheap [crudely-made] alloy spacers are available from www.overclockershideout.com at around $2; superior
copper spacers offering some additional transfer of heat are available from www.plycon.com - at $13 [!].
