Hmm, I can't be bothered to do that amount of machining, just for a
heatsink. Thinking about it, for my application I use an RTC module
which definitely won't fit.
Ho hum, sounds like one of those good ideas that turn out not actually
that good.

Which is the first kit I bought for the pi4. But the padding materials
protective films could not be removed without trashing the material, so
I ordered some more, but all I could find was startech and it would have
taken ten sheets of that to match the thickness of whats supplied. In
the meantime I'd measured the oem stuff and found it to be somewhere
north of 1.8mm thick. So I took 1.8 off the legs, then 1.5 more off the
thicker section above the mini hdmi sockets. Then I found I'd need to
plow a trench above the audio jack, and lengthen the 2 cutouts for the
camera connectors. I could continue, and maybe eventually make the
pillars touch the chips which are clearing them all nearly 2mm right
now.
But I was out of places to get a solid grip on it for more machining. So
I ordered 2 sink kits. If and when its installed, there's a fan under
it. Been cooling a pi3 that way for 2 years now.
Oh and I had to machine a couple mm away from the 40 pin header so a
header connector would fit, which is how I wrecked the oem thermal
padding in the first place.
After 3 days standing in front of a 6040 mill, fine tuning my gcode, I
gave up. The lack of room engineered into that heat sink sandwich,
plumb ruins any chance of being able to use that kit efficiently.
Header extender's might have saved the day, but I was not aware they were
even made until I'd already carved this one up trying to make it
actually fit, I'd have to start with a whole new assembly. Another 3
weeks to get it. And I've not measured to see if the additional height
of the extender's is usable without moving the fan.
Nothing I have tried to do with this pi4 has worked OOTB Except the
debian net install. And its spi was broken when I tried to install the
program I bought it to run.
Time maybe for a break until I get my aortic valve replaced next week.
Its leaking badly from 85 years of wear.
Thanks Les.
