Wanna ask a question:

Is it radiation-safe to put your palms and hands on this very mighty
very great PC? Wifi (tri-band: 2.4GHz, 5GHz, 6GHz), GPU, CPU, various
chips.. all emitting some kind of radiation.

And the heat.... might be great as a hand-warmer for people living in
cold places. How about cup-warmer? :)

The processor is 15W. That's the lowest processor in the 300-series.
The processor has an NPU (50 TOPS). I don't expect the NPU
will get to run for very long, before it and the CPU portion
are thermally throttled (clock-rate reduction, instruction-rate
reduction).

Microwave radiation is no joke, and we seek to remove it in situations
where it is avoidable.

If you hold a smartphone to your head for long periods of time,
that can lead to a "glioma". But the cancers are also naturally
occurring and can occur in pediatric situations.

"A brain glioma is a tumor that starts in glial cells, the brain's
supportive tissue, and can occur in the brain or spinal cord,
varying from slow-growing (low-grade) to aggressive (high-grade)."

Some of those are operable.

Your hands are not your brain, they're a different kind of tissue.
Your hands contain bones, muscles, nerves, skin. You will notice your
hands are already susceptible to cancer, such as skin cancer from
the sun (melanoma).

The smartphone is more likely to need to use a bit more RF power to
reach a tower. In a business (where these keyboard computers would
be used), there could be a 4G microcell inside the building (as office buildings with a lot of metal, don't have good RF penetration
for services). This means the smartphone automatically becomes less
dangerous, because it can turn down the transmitter when it senses
the tower (microcell) is "really close".

The Wifi is the same situation. Using Mesh Wifi in a business, the
active element can be in the same room with you, and the keyboard
can turn down the Wifi transmitter because it senses how close it is to the other receiver. The Wifi power level, will be lower than it is in
your house right now, where the router is in the other end of the
house.

The keyboard is not pressed against your head.

I think you're safe.

I don't leave Wifi running here, that is not performing a function.
Right now, the (intentional) 2.4GHz level in the room here is zero.

I don't think that keyboard has an Ethernet port, but you can
add one (ASIX USB to Ethernet). You could also reach into the unit,
and unplug the Wifi module. Because the keyboard only has two connectors, that's one of the major reasons I would not buy one! It should have
more connectors, for user convenience. Three ports is a minimum.

That's also security and safety. :)

It's still better to do things the good old way, that's a computer in a grounded metal chassis a feet or more away from me. It's MUCH MUCH MUCH
safer! :)

Can glass block EMF radiation?? The industry is pushing glassed computer chassis.

For systems not intended to emit an RF signal, just the
PCB is sufficient to block interference. The clock signal
is buried on an inner layer and there is a copper plane on
the outside at ground potential.

Computer case designs have been "leaky" for a lot of years,
and we do not rely on the computer case as a shield. Containment
starts at the PCB level. The Y caps and other filter components
on the inlet side of the power supply, they're intended to prevent
some noise-on-mains from escaping.

And the products are tested for emissions.

The USB3 cable can emit under some circumstances, because it's
a 5GHz signal, it emits a broad spectrum centered at 2.5Ghz.
This can wipe out a Bluetooth transceiver. If your Bluetooth
can send files to a second Bluetooth equipped computer, this is
a good indication that your USB3 cables are NOT emitting :-)
You can then unplug your Bluetooth nano transceiver and stop using it.
My Bluetooth nano transceivers are unplugged right now, but they
sit next to their computer and can be plugged in when needed.

*******

If you want to see a test instrument for electronics, where the casing
is a necessary part of the filtering, that is the Spectrum Analyzer.
It uses a honeycomb cover on the air path, to block external RF from
getting inside the box.

https://www.uaf.com/solutions/dual-emi-air-filters/

It uses beryllium copper gaskets between cover plates and chassis,
to make a Faraday cage around the electronics. The noise floor inside
the Spectrum Analyzer is -135db to -150db or so.

This allows the instrument to make measurements of external signals
on a scope cable or similar, and any other stray noises do not upset measurements the instrument makes. It does allow the instrument to be
air cooled, but it is pretty hard to push air through the physical
packaging when so much effort goes into sealing up holes where interference
can get in.

Computers, they only have to meet FCC part 15, and they don't pass with exceptional margin. The computer companies expect their engineers to make
good PCBs, such that a finished product only has to be sent to the
third party testing lab one time. That's the main reason the PCBs filter
as well as they do, is the manufacturer does not intend to waste a lot of
money "forcing" the design to meet the spec. What we used to do, many years ago, is "improve the case design to stop emissions" which is expensive.
If you can stop emissions at the PCB level, it reduces the need for
"RF tight" packaging on the outside. That is why a "glass" computer
case works.

What if the motherboard suddenly leaks radiation? Can a causal user
detect or sense it?

By one's 8th sense? :)

Don't think of it as radiation, the core of the motherboard
would be a source of electrical interference.

If the motherboard was damaged to the point of interfering
with external things, the computer would crash. That's because
a loss of signal integrity means the computing stops. And with it,
a lot of random interference.

This is also the reason you cannot prototype high speed CPUs
with a protoboard (plugin wires board) and a bunch of long
loose wires. The signals arrive distorted and the CPU won't
work. The thing you are describing would have the same result,
the CPU could not stay running if the PCB is damaged.

Don't wanna waste your time. I will keep your info in mind and see how
things actually go in the future. Thank you first! ;)

BTW, have you ever considered the slightest but evil possibility that heatpipes in giant CPU/GPU coolers might contain radioactive fluid? :)

And customers have no way of discovering this!

The fluids are very safe.

The very first heat pipe (more of a heat chamber) was
done for some DEC computer CPU. The guys used an alcohol
for the working fluid. They were, of course, crazy people
for having done this. But this was a lab experiment to
see if it could work. They were testing fluids at 1 ATM,
and not attempting to alter the boiling point.

You don't have to do that. You can use water for the
working fluid. By manipulating the quiescent pressure
inside the heatpipe, that affects the operating
temperature range. The quantity of fluid is minimal.
Inverting the cooler, there should be NO sloshing noise.
A heat pipe today, might have two drops of fluid. It's
not a lot. And the water can flow uphill, because
the pipes are sintered inside. And via capillary action
the water runs uphill during phase change. A heatpipe in
the wrong orientation is not super-efficient particularly,
but the water keeps running uphill to some extent. Before
they added internal sintering to the pipes, a heatpipe
would shut down if inverted.

If the thermal load at the source is too high, all
of the working fluid only exists as vapor, and it
will not condense. The behavior of heat pipes is
non-linear at some point. And you must pay attention
to the thermal rating when using a heatpipe, for best
results. If you have a 238W Intel processor, then
a 250W cooler would be a good fit. Fitting a 132W
Noctua would not be a good idea. Since the CPU
has "throttling protection" and PROCHOT, you cannot damage it
by using the wrong cooler. But to get the best execution
speed from the CPU, the correct cooler (250W) is a must.
