MacBook temperatures with eGPU, any better?
The main reason why I bought an external GPU is temperature. I never needed one on my desktop computers but now with a shared portable I’m in big troubles.
These are the temperatures I’m talking about:
Idle or Safari, iTunes, Mail
System Updates or Maintenance
Final Cut Pro or ffmpeg, Photoshop
I believe these temperatures are not suitable for internal parts, like CPU and iGPU. I know this because my 10 years old iMac it’s 1/2 the performance now with a far better system installed. I also tried with 2 140 mm fans below the MacBook Air with no luck.
Other reasons than that are of course performance boost, multiple monitors, devices compatibility, portability and price.
Update: with eGPU connected and heavy GPU apps running the difference is huge. Temperatures dropped with fan around 2200 rpm all the time.
