AR750S getting very hot?

So I have been using the ar750s regularly since I got it a few days ago. I noticed that it is getting very hot. Is this regular? What is the regular operating temperature of it? Anyone else noticing this heat.

Mine seems no warmer than average.

Mine has max. 37°C on the top cover with a load of 11 wifi devices + two ip lan cams.

Yea for some reason mine seems to get quite a bit hotter than 37°C, only extra thing I have in there is a microSD card, I’ll have to at some point get a laser thermometer to check the actual temp.
