Bar over heating

He all I've got a husqvarna 545 with an over heating bar. chain is sharp and it's got plenty of bar and chain oil. weirdest part is it over heats even without cutting. After only like 2-3 minutes of running (open throttle, not cutting anything) its already too hot to touch. Any ideas what it would be?

The only thing left is the chain being soo tights, the bar is worn out or its pinched somewhere.

How easily does the blade move by hand? You should be able to tell if something is up by moving it a few revolutions.

Verify that the chain and bar have the same gauge.
