No, for metal to be an effective conductor it has to be in
contact with the hot parts. Even with hard drives mounted
in metal bays, one can see from the side of the drive and by
taking a finely made straightedge, that their sides are only
flat enough to be in contact with a small % of the metal.

Wrong when the flexible drive bay stack is screwed up to the drive properly.
And proper electrical grounding of the components and motherboard.

Oh no! Rod disagrees!
Pity you don't actually look at the drive, look at the case,
or notice that for the metal to bend that much it'd have
permanent creases in it.
Maybe your cases are built like tin-foil. That'd come
closer to doing what you suggest but mine are a wee bit to
thick.

Never ever could bullshit its way out of a wet paper bag.
Never could explain how the metal drive bay stack ends
up at the same temp as the adjacent drive frame metal either.

"Case"? What is this "Case" :)
They all say that you need to ground everything correctly, but on decently
made parts, it's not a problem. Basically, they look nice, and wont break
(sending expensive parts to break each other ;)

I have 4 cases in use and only one even makes metal to metal contact
on the hard drives. The Dell cases at work have no metal to metal contct
with drives, so that puts him at *BUUZZZZZZZZT!!* Wrong in a vast
majority of computer cases.

Lets see, I have three hard drives sitting here right now. Laying a
steel ruler across the mounting screw holes I see; ha! whataya know,
there is a raised area around all three screw holes so when you tighten
all three screws only about 1/8" actually makes metal to metal contact.
Looks like you are, yep, wrong. And as I pointed out earlier, that is
ASSuming that the particular case in question has a mounting solution
that actually provides metal contact, most don;t these days for reason
of noise concerns. You can't back out of this one.

No you can't. When you're right you are right, but when you are

On my Lian Li it doesn't. The rack gets warm, but not nearly as warm

Bullshit.

Fraid so, there are plenty of cases that have
proper metal contact in the drive bay stack.

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.

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 fucking 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.

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.

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

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 bullshit artist.

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

So your original claim that you carefully deleted from the quoting and I have

Nope, not with the hard drive frame.

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

Wrong, you pathetic excuse for a bullshit artist.

Wrong again with hard drives.

The thickness is completely irrelevant, its the increase surface

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

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