No, I haven't had any hands-on experience so far. I will update as soon as I get some. I don't think there were any excessive noise from the ThinkPenguin laptop, should eventually try to fix it (mechanical problem, should be possible to mend it somehow ... I do have both epoxy, duct tape, glass fibre and polyester i my tool box ...)

It's quite common in modern laptops that all the power saving (even adjusting the fan speed) is supposed to be done by the operating system, at the same time different laptops may require very different configuration - hence a laptop with a pre-installed operating system (pre-configured and tuned exactly for that laptop) may work out better than when doing some generic operating system installation in the aftermath. On some Linux distributions it's needed to install some power management package (like laptop-tools or tlp) in addition.

Now that "everything" runs in a browser, and even devices without a fan (such as mobile phones and Raspberries) have sufficient computing power to run browser applications, fan noise ought to be a problem of the past.
