A little updated here.
finally spent the 2 hours to lap my TRUE.
Idle temps only dropped 1 to 2C.
Load is where it shined.
Dropped temps around 7C under load with prime.
running around 63C now from 70C.
It did not even out my core temps as much as I would have liked but the delta is only 2C where it was 4C before.
Definitely worth it especially if you got an older true which came with only 1 fan bracket. feel the bottom of it and you will feel all of the grooves in it. Mine is now shinny and copper.
