Meanwell 48D LED Driver Heat Issues. Anyone else???

[GvineReefer]

I've got a custom Cree/Meanwell setup with a 50/50 mix of XPE's and XPG's, so I like to keep my blues brighter than the whites. The Meanwell ELN 60-48D drivers are mounted in my stand and they get pretty hot after they've been on for a while. Last night I noticed my lighting not looking the same, so upon investigation, I saw a string of my blues was completely off. I fiddled around under the stand and felt my drivers, scorching hot. I left a door to my stand open for a while and I later saw that the string lit back up, but ended up turning off again. I imagine it cooled down, then heated back up once it was on for a while.

Anyone else having similar issues? It's looking like I either need to put a fan on them or I've got a bad batch, because they all get fairly hot now. This is the first time I've had this big of a problem, so open for suggestions.

Thanks

what current are you driving them at and how many LEDs do you have on that string?

I had the blues on a higher current, but don't remember which exactly. I have 4 drivers with 12 on each string. I may just be running them too high, so I'll turn them down a bit. They have always gotten hot though, no matter what current I have them on. I'll be switching these lights over to my new 120-gal soon, so I'd like to figure out if I need to mount them somewhere else too. Keeping them in the stand may not be the best idea. I might be able to mount them on the back of the stand...
