OK, so "after" phase change hump goes through, it's stabilized at the same temperature as the normal paste tp4 was using.
Liquid metal is only 1-2 celcius better
So it's close yes, but Liquid metal is still the winner.
Tp4 can't test longevity in 1 day, so we'll see how it fairs down the line,
Thankfully, regular paste's pump out behavior is really obvious on the GPU, so Tp4 should be able to notice it quite easily given some time.
Will bake it for a bit more at a lower fan speed and see if it gets any better.
So the claim is pretty close, it comes down to the longevity now.
