I don't have one, and I haven't seen one in person, but ExtremeReviews
has this table of specs:

(can also be seen at <a style='text-decoration: underline;' href="http://www.coolmaxusa.com" target="_blank">www.coolmaxusa.com</a>)

It says that these PSUs reach 75-89C in 25C ambient air, meaning
they'll probably be 10C hotter in actual use at full load (but almost
nobody applies full load, only 200-250W at most). The transistors and
diodes supposedly can run that hot without problems, but what about
any nearby electrolytic capacitors or wire insulation? I can't
imagine this PSU having bigger heatsinks than a PC Power & Cooling or
Tagen, so shouldn't it run hotter, despite all the vents in its case,
especially because its rated efficiency is just 60%? OTOH this
Coolmax may be the only fanless ATX PSU without exposed heatsinks,
which may be why it's the only one that's UL approved.<!-- ~MESSAGE_AFTER~ -->
