The #IntelArc #A310 looks like the card of choice but there appears to be no card with a proper fan design available right now. There is only a super noisy #Sparkle variant with a blower fan design with several reports on this specific card to have high fan noise and a terrible fan curve. Urgh.
So I looked at the alternative #A380 at pretty much the same price, which can be run at ~5W when idling. But there is a problem: Intel Arc cards drain 30-40W when there is no #ASMP enabled to allow the card to low power states: https://www.intel.com/content/www/us/en/support/articles/000092564/graphics.html
Well, ASMP is only supported on newer hardware so I had to to check my mainboard (AMD B520 chip) for support. (2/?)
