LED Power Supply Temperature

So today I somehow ended up on a thread about the ReefLED power supplies getting overly hot and it made me remember the one time I brushed up against the power supply to my atlantik orphek LEDs and how hot that was. I went back and and touched it again to test and I pretty much can only keep contact with it for 2 or 3 seconds before it gets too hot to to touch anymore. I also have AI primes so went to check those out and I can grab and hold on to those power supplies forever. I always assumed it was normal for the power supply to get this hot but maybe not? Does anyone else have their power supply get this hot?

I think how much heat produced will depend on the power draw. On my Kessil a360we they're warm like my Hydra 26HD. But they do get warm enough that the velcro adhesive won't hold.
