[c-nsp] heat fins popping loose on WS-X67xx cards

[Jon Lewis]

That's a fairly common (but seems to me stupid) design.  Basically a U 
shaped jumper block used to anchor springs holding a heat sink in place. 
My home desktop motherboard had one pull out just like that.  I superglued 
it back in place and the repair outlasted the rest of the board (a few 
years).  Capacitors on the board ended up failing forcing me to upgrade.

I don't understand why they don't bend the legs under the circuit board to 
make pulling out less likely...or even do that and then either weld/solder 
them together.
