I suspect fanned rads will make a comeback some day once people realise

s/fanned/finned/ ?

Not sure what that means, but they do tend to go together. A fan with a flat
panel works for a diy job but is not optimal design costwise for a new
product.

All you need for a fanned rad to work, take up way less space and be much
preferred is silence,

I can see how you get quiet for a reasonable amount

But silent?

and that's not a challenge.

For you, maybe :-)

If an engineer isn't able to design a silent fan they had better stay out of that business.

Moving any volume of air around inherently creates noise. An engineer
would know this, otherwise they best stay out of that business.

I take it you're not an engineer then. Or an ignorant one.

Hint: try turning a desktop fan round by finger & see how noisy it is. No wind noise.
