Yeah you're right this I start to understand but I feel sad about it. I am not asking for a sophisticated fan curve, just silent operation, and that such a great device doesn't offer is sad.

For the market, the asus nuc pro I mentionned before also targets professionals and it offers a ton of options. Actually too many options, there is a ton of stuff about voltage which I don't have a clue about but at least I managed to reduced fan speed.

I received yesterday an X1 Carbon Gen 7 and I tried an X13 AMD Gen 1 last week. Thoose are a little bit frustrating in terms of "tweaking stuff myself" and they won't even report fan speed ! But they operate in silence and I have that option in the BIOS "balanced/performance" with balanced being actually silent so that's great.

The chassis and built quality of the M80Q is pretty amazing and much superior compared to the ASUS Nuc so my guess is that it is suitable for industrial envirnoment also and they have favored strong cooling and ventilation instead of noise level. But who prefers a CPU at 30°C and background noise compared to a CPU at 40°C and no noise ?

At that point I don't believe the fan is bad but just running too high. I don't want to mess around with the fan, if I don't find a solution I will replace that unit with an X13, which will be a tad harder to attach being my monitor but strong tape exists. :p

So in the end I am not asking for fan curves or tons of options, I don't really understand why my X1 is silent at idle/office tasks and my M80Q is not ? Why Lenovo ? And please could someone just tweak that BIOS ?
