Laptop + egpu instead of desktop

I've been trying out egpu with an macbook pro for a while and it works ok, but I'm interesting in experience with long term experience of this under work conditions. Can you get by on this instead of using a dedicated desktop for medium to heavy use? Or is it a bad idea.

User case: Blender, Unity3D, Final Cut Pro, Photoshop, Visual Studio

I had a Mac Pro2,1 32gb ADM7950 3GB  before and switching to my current setup was a great move! But I think it depends on what you have now and what you need for the future.

The laptop gets a lot hotter then the Mac Pro did but if been working on a vented desk to compensate. GPU performance are great. Both in FCPx and when playing some games.

Yeah,

The thermals is what worries me the most long term. I see that the cpu cores run pretty hot when doing 100% CPU. Doing heavy work will make those hot sessions a lot more frequent.

Do you think the fan noise is disturbing under prolonged heavy use? A desktop can run a lot more silent.

What is the best solution for cooling a mac book pro on the office desk? I have it slightly elevated. Does a rising stand does a lot of difference for cooling? Cooling pads doesn't seem to do much as the mac book pro air intakes is on the sides and the outtake on the back.

I use headphone most of the time or when I don't volume of the sound is high enough that I won't hear the fans. 

At the moment im planning to make 2 120mm holes in my desk and put 2 Noiseblocker fans under them blowing against the bottom side of my MacBook.
That will work a great bit I guess.

My Mac Pro would get more noisy when under load. It what configured with 2x 3,0 Ghz quad core's. It was a beast. Stil mis looking at it...

There are quite some website writing about cooling pads for the Mac, I guess that isn't for a reason. Unfortunately, there are no temperature comparisons to be found. Out of experience, I can tell I bought one from amazon, the top ranked are all around €20-25, and it definitely keeps the aluminium outside cool. While doing intensive 4K gaming with my MBP 2018 13,3", the chassis keeps feeling "a little bit warm". As comparison: when playing a youtube video on the couch without de cooling pad, or sometimes even just browsing, the MBP chassis gets way hotter.

Unfortunately, it's not a really reliable review of course, but I can't imagine that this cooler chassis has no effect on the internals as well.
