Yeah I have the same problem. My fans go crazy when I play for more than 5 minutes. I have all graphic configs low btw...

Delpi and Druachan, thank you for replies.

I keep my laptop on a stand so it vent well, plus game settings is mid. It just weird, I run virtual box and some ides and it doesn't overload the system as much as this game alas. Anyway, let's hope guys from eso do optimize the game.

Druchan, thank you for the articles, they were useful

altemriel, thank you. I might think of changing cooling pad.

I have a 2015 MacBook Pro. I have ESO on there for times when I can't use my iMac. So I then added fanny widget,
http://fannywidget.com silly name but oh well Anyway while playing eso the temperature would hit about 62 degrees and the fans would be blowing pretty hard. Some checking with an intel site says the cpu should not get above 95 degrees, if it does your MacBook Pro will shutdown to prevent it overheating.
So if you are worried then install something like fanny widget, something that shows the current temperature and check how hot it's getting. Definitely keep it off a surface like fabrics or so that will only make it hotter. So a stand or cooling pad would help.

Just for you guys i did a bit of testing by running through a delve in cold harbour with my character to see what happens to the temperature. My character says she didn't mind being mashed in the pursuit of research ;-)

so my graphics setup is as follows



At idle the temperature is 41 degrees and when the game is launched it goes up to 57 degrees.

I took some screens of the temperature at various parts of the delve which I've shown below. So its getting warm in there but not dangerously warm.



I found that being somewhere busy with players like rawl'Kha or vulkhelguard also increases the heat. though not beyond the mid 60s.

So I'd say, is your MacBook overheating? probably not, if it was it would shutdown, its definitely working hard though.

I used to freeze shotglasses of water and balance them on my mac to keep it cool during ESO play. I had two sets I would rotate from computer to freezer, along with some whisky rocks. If I was on point with my ice rotation, I could play for an hour before it critically overheated and shut down.

Ah, good times.

Thank you all for replies. Druachan, super screenshots

I've installed istats to be able to see information in terminal. Actually, it is very convenient. And I wrote a simple script that stores logs of cpu sensors (all 4 cores) and was able to see the temp changes during 15 mins.

Launched the game

When I'm not using the game the istats shows me this

$ istats --no-graphs
--- CPU Stats ---
CPU temp: 32.38°C 

--- Fan Stats ---
Total fans in system: 2
Fan 0 speed: 2168.0 RPM  
Fan 1 speed: 3381.0 RPM  

--- Extra Stats ---
TC1C Core 1 temp: 43.0°C  
TC2C Core 2 temp: 36.0°C  
TC3C Core 3 temp: 36.0°C  
TC4C Core 4 temp: 35.0°C  

Well, the articles guys shared are pretty nice though. Could decrease temp from 95 to 85-90.
Gonna search for other issues that might cause the overheating.
