Heatsink upgrade project going well.  Test unit with original 2Pac finally finished and going through post-upgrade stress testing.

You're not seeing things, it glows under UV light...

The 2 x NewPacs have been disassembled and awaiting conformal coating to dry before heatsink upgrade.  Waiting for tiny clamps from Amazon.

So far with the upgrade 40x40x20mm heatsink, she's running just slightly above room temp doing stable at 175MHZ on a lousy Anker USB hub.  Run so cool my thermometer refuses to measure temp (I'm using a human thermometer since I don't have an electronic or cooking thermometer).

Will be upgrading the NewPac with a 40x40x20 and a 60x60x10 and see how each does.

I think I need to order a few more NewPac sticks...
