You claim to be regular without displaying any evidence thereof.

Doesn\'t being regular just mean having free-flowing sh*t? Or is that
just a UK interpretation?

Toothpaste1C
Banana 58C
Paper 67.2C
Yellow cheese 67.9C

I focus on the ability of the material to provide a liquid interface
between the cpu and the heat sink. Even the regular thermal paste dries
out and must be replaced.

If a liquid is needed, why not use ordinary mineral oil? It\'s probably
better than butter, it doesn\'t dry out, and capilliary action will cause
it to form a uniform film between the cpu and the heat sink.

Any thoughts?

Here is an article describing more. Notice the first sentence includes an
oily interface material. Mineral oil, perhaps.

Thermal paste, or some oily thermal interface material, is necessary
because it fills in the microscopic imperfections that otherwise
trap air particles between the CPU and the heatsink, preventing the
CPU from properly cooling. Heat radiates outward from the CPU to the
heatsink, before eventually making its way to a fan where it
disperses; but, since air is a notoriously poor conductor of heat,
an outside element is needed to bridge the gap between the two
components.

Very often, assemblers and computer repairers do not have thermal
paste available. It is a fundamental component because it helps

Sorry, if you don\'t have the basic supplies or tools for computer repair,
you\'re not an assembler let alone a repair tech.

i lost my access to said thermal compounds when moving my residence. i
went to the local compute repair shop and ask if he could put a dollop
of heat sink compound on a bit of plastic and charge me whatever he
thought was fair. He shot back with \"that wont pay my rent\", which is
true, but it would have gone a long way to buying his lunch. So I went
to the pharmacist next door to his shop and bought a tube a zinc cream.
That works even better than the proper stuff.

I tried to find out what\'s in it but no luck.

How do you know that it works better?

Does it dry out? Why not?

IIRC the temperature was a degree lower than with the (then new) thermal
paste. In the happy land of OZ they have to print what is in it on the
product. (some also contain titanium oxide - I avoided those. May have
been a good decision or a bad one. I don\'t know)
