I think you got that from me :)

I think this one's name should be "Nothin' but Trouble" !!!

So did I. Was right astonished to see 'em at that price new-in-box, but 
was from some server recycler outfit and probably nothing their regular
customers could use.

And apparently considers electronics to be a form of plumbing!

Sometimes older CPUs in the same class do run hotter. But that's kinda  strange.
I wonder if the board the old CPU is on is underclocking it. 
Which is usually an option if temperature can't be otherwise controlled.

Not very good at all, in my view.

I've had some stuck on by twisty tie or external screw myself. These 
tend to become permanent. <g>

Heatsink fit depends on the mount, not the CPU. Some are directional, 
others don't care.
