No Rod, it is extremely rare to find ANY case that makes a
very large % contact. Even on the best example you might
have to slop a few ounces of thermal compound on the sides
of the drive or use thick pads.

No Rod,

We'll see, gutless...

That comment was clearly about cases that have ANY metal to metal
contact. Some dont, they have rubber mounts, not metal to metal contact.

Not a ****ing clue, as always.

Have fun explaining how come the metal drive bay stack
is the SAME temp as the drive frame in that area.

I'm talking about cases with only metal-metal contact too,
the % contact is very very low, and what little of it there
is, a large % of that is painted but barely flat, not
machined flat as right over the screw holes.

It isn't.

Have fun explaining why you don't realize this.

Irrelevant to what we were discussing there.

Wrong when the drive is screwed into the metal drive bay stack properly.

That ends up with more metal to metal contact than you
get with a TO-220 power transistor and thats fine to
dissipate the sorts of power that hard drives dissipate.

and what little of it there is, a large % of that is painted but
barely flat, not machined flat as right over the screw holes.

Doesnt need to be. Where the screws go amounts
to more in total than you get with a TO-220.

Keep desperately digging, you'll be out in china any day now, AGAIN.

No, there's no "proper" way that magically makes two
non-planar surfaces melt together into perfectly parallel
ones.

If the screw holes are machined, you may indeed get more
total contact area. The remaining problem is heat density,
with the TO-220 you have a short relatively more efficient
path to 'sink away the heat, while with a HDD frame, having
a small % of the TOTAL area sunk, does very poorly. It's
not actual surface area that counts, it's % and thermal
gradient. Well there's also that the drive bay metal
itself is far too thin to be a good 'sink too, and that is
why you'd notice even a little bit of warming in the area,
because it's such a poor conductor that the heat isn't
spread out effectively.

Further, this does practically nothing to cool any PCB chips
not 'sunk to the drive frame.

You aint established that they are non planar, you pathetic excuse for a bull**** artist.

melt together into perfectly parallel ones.

Dont need to be 'perfectly parallel' to do better than % contact
is very very low, you pathetic excuse for a bull**** artist.

So your original claim that you carefully deleted from the quoting and I have
restore is clearly just plain wrong, you pathetic excuse for a bull**** artist.

Nope, not with the hard drive frame.

path to 'sink away the heat, while with a HDD frame, having

The total is completely irrelevant to the area that the heat
conducts thru fine, you pathetic excuse for a bull**** artist.

It's not actual surface area that counts, it's %

Wrong, you pathetic excuse for a bull**** artist.

and thermal gradient.

Wrong again with hard drives.

Well there's also that the drive bay metal
itself is far too thin to be a good 'sink too,

The thickness is completely irrelevant, its the increase surface
area that matters, you pathetic excuse for a bull**** artist.

and that is why you'd notice even a little bit of warming
in the area, because it's such a poor conductor that the
heat isn't spread out effectively.

Have fun explaining how come the entire drive bay stack
metal is equally warm, you pathetic excuse for a bull**** artist.

Further, this does practically nothing to cool
any PCB chips not 'sunk to the drive frame.

Irrelevant when their temp is fine. What matters is getting
rid of the 10W or so thats being dissipated in the drive.

It's not equally warm. Do you ever pretend to test these
grand theories you dribble out?

Fraid so.

Completely trivial to test that, you pathetic excuse for a bull**** artist.

I don't understand why anyone even bothers to argue with him...
