Considering how common massive thermal issues are in prebuilts... yeah I'd say AMD is spot on in adding sensors to measure ambient temp in the case. Just because we know better doesn't mean multi million (or even multi billion) companies do.
Have you seen most SFF builds?... they don't know the meaning of the word airflow... And as @Anfield said, neither do OEMs who are still using in 2022 case designs that were first stamped out in 2002.
In my case, Fractal Design Define R5 and 5 140mm fans do the job. Quiet and cool. Added to which, my big clumsy hands wouldn't work well in a midget case. BTW, a long time ago I bought a case from Currys, with one small intake vent and a single fan, exhaust behind the CPU. Was OK at first, until I upgraded. With a Core2 Duo and an unnamed new graphics card (no memory of what it was...) it sounded like a Dyson V10 on max power and, ran hot...
Just seen that Gigabyte are launching a white RTX4080, available from Monday. Worryingly, that makes it suit my current build!
I do believe you're talking out of your arse. Most SFF enthusiasts are keenly aware of airflow requirements.
Scan are having a " RTX4080 launch event" instore on Wednesday at 2pm, with actual stock on the shelves. EDIT - Forgot to mention this is an IRL event.
I tried to watch some review vids but... CBA My 3090 is far more powerful than I currently need, so I have zero interest in anything Nvidia is doing right now. Especially considering their efforts to put scalpers out of business, by gouging their own customers. I do hope AMD kicks them squarely in the nads, come Dec 13th.
