I haven't had a problem with Garrett or most turbochargers.

1. ) Doubtful, but operating outside or exceeding efficacy zones will result in heat.

2. ) Your exhaust system could be restrictive at a particular point and when you get into prolonged high rpm usage such as on a track this could raise exhaust gas temps.

3. ) Upon installation, you did not prime the turbo with oil. It theoretically ran dry. Or you have some form of oil flow / feed starvation. Possibly too much pressure. I have seen that. You want flow but massive oil pressure.

4. ) 500mi is definitely abnormal. Defect from who or wherever you sourced your turbo.

A lot of variables. All depends. Those are things to consider.

In terms of cooling. Oil is the blood life. If you aren't receiving it or enough bad Ju Ju all day. Assuming all of the above is not applicable.
You could add a small mechanical or electric water pump. A small radiator seems most logical with a fan and thermo.

Something's up. You need to triple check. A lot of machines run lean AFR's or some of which run retarded amounts ignition advance.

Good Luck -
