I used the ones you said did the worst to build some fan cooled 532nm DPSS lasers in aluminum cases about five years or so, ago. They were screwed down to the aluminum enclosure with Arctic Alumina Thermal adhesive and had unlimited run times at 200 mW. I couldn't use a heat sink that didn't contact well with the enclosures, so these worked out pretty well. considering they had 1 watt pump diodes in them.
