This is an update of my previous setup, you can find it here:

I changed the Laptop from Acer Triton 500 to a Razer Book 13, keeping the Zotac RTX 3070

The thermal performance of the Triton 500 decreased notably over the months. It got pretty hot pretty fast (despite dust-cleaning and CPU uV).
The problem according to sensors was the cooling area around the internal RTX 2060: even with the dGPU inactive, the Laptop's GPU area heated up to 80 degrees. I had to put both of Acers graphics-card fans to around 4000+ rpm to bring thermals ~70 degrees. The i7-9750 was constantly around 90 degrees which also seemed too high (the Acer Predator Sense is actually a nice tool to play around but that was a small feat).

To make a long story short: the noise of the Laptop started to bother me and CPU-throttling obviously became an issue.
Because the 3070 is literally silent in the Breakaway Box (see original review) I gave the Razer Book a chance hearing of the new efficient Tiger Lakes and the availability of 2 x Thunderbolt 4.

The result is pretty impressive in that regards that I have a slightly better performance at drastically reduced noise and thermals. The Razer Book is silent without any uV.  The 2 fans of the i7-1165G7 do not even bother to wake up on Prime Stress Test and the 3070@Sonnet is as quiet as before.

Some additional objectives:

  • Timespy Graphics performance now is ~200 points higher vs. the old setup although its the same graphics card AND Timepsy CPU score is lower. My only guestimate is
    either the super-fast RAM of the Razer or the TB4 interface give the graphics card a boost
  • uV is not possible with Tiger Lake at least not through Throttlestop. However, I am not sure if this is required: After 3:30 h of 3D-Gaming the i7-1165G7 averages 60 degrees @ 3666 Mhz average clock speed (according to HWinfo); the 3070 btw averages a mere 55 degrees (1500 Mhz Clock average)
  • Obviously, there are performance reserves through oc'ing or uV the 3070 but currently I see no need

In sum, it's a clear upgrade from a noisy to a silent eGPU setup. The main downside (while using an external display) is the reduced connectivity of the 13" Razer vs. the 15" Acer which in this case I take as a tradeoff. The Razer Docking station can solve this problem but at a whopping 350 EUR it might not be everybody's choice.
