### BIOS & EC upgrade
+
All devices sent after the middle of May seem to have BIOS version of at least 1.04 (there are reports of a newer 1.05 version which is not publicly available yet), so you probably don't need to do anything. Otherwise the only officially supported way is using Windows. Something like [Hiren's BootCD](https://www.hirensbootcd.org) could be used as a more convenient option.
### Cooling
EVO-X2 has a decent cooling system for its size and the used thermal interfaces are great as well, so changing thermal paste for example to even something like Noctua NT-H2 won't change much.
