... please do describe the heat path to us, Rod.
The chips create same heat, either cooled on their surface
or through the leads to the copper on the PCB. That PCB
must also shed the heat. Let's suppose they have a really,
really advanced design that somehow 'sinks away the heat to
the metal drive frame.
Even then Rod, THAT SAME SIDE OF THE DRIVE is what needs the
Since you were off to such a lousy start again, I went ahead
and snipped out the rest of the nonsense.
In a chip, but unfortunately, having that one point temp
measurement is not any guarantee that some other chip on the
same PCB, or the bearings, etc, are cool enough.
The Zalman product does as much as they can do, not being
able to custom design to cool many different drives which
are a moving target over time.
Unfortunately, the sides of a drive's frame are not very
important to cool relative to the rest. It'd be better than
nothing but far worse than (and completely unnecessary if
you have) a typical bay where all the chassis intake air
flows through it.
It may help cool the motor some but the product could not do
very well for the purpose of total drive cooling. Even if
it did a great job sinking away heat from the sides, that is
not the goal, it is distanced from the source of the heat so
not very effective at cooling the hottest portions of the
Heatsinks applied with frag tape to any hotter areas should
do better, be cheaper, but still unnecessary given a good
rack and flow through it. It just isn't hard to cool
drives, quietly, when routing the same airflow the system
already needed, past the drives first.
Hmm. Well, I'm looking at 18C right now. The wall thingy says 16C. Cool
breeze coming in. The HD is a Samsung SP1203N. It's in a 5 1/4" bay on
rails. I've drilled 3 holes in the slot cover and in the one below it. The
PSU fan is 120mm and running at 1250 rpm.
Weather online says 18C.
Too, the cpu heatsink is ducted by aluminum tape to the 80mm case fan
running at 1800 rpm, so the only cpu heat in there is radiant heat (I'm not
It's really quiet. The fans are quiet models.
The gpu is a 6600GT running 2D at this time. But I don't think that heat
gets up where the HD is in the 2nd slot from the top.
If I run the psu fan slower the HD temp. goes up.
With more conventional room temps it runs in the high 20's and gaming with
the room warm in may reach into the low 30's.
Pretty neat, eh?
I think a newer drive may run hotter.
Just how many of you are there between those ears, gutless ?
And when you are so stupid that you cant even manage
to work out what those screws that hold a case front onto
the tube go thru with the tube, its a tad unlikely that you will
be able to manage something a little more complicated like
how those Barras get rid of the head from the logic.
Even if someone was actually stupid enough to
lend you a seeing eye dog and a white cane.
Wrong when there is a rubber mat between the logic
and the metal plate on that side of the drive, child.
Never ever could bullshit its way out of a wet paper bag.

He didn't you retarded fuck. He was talking about a plate that was
attached to the PCB on a particular drive.
It was YOU that came back thinking he was talking about the lid.

Could be right on the PCB, or could be a remote sensor (off the shelf
flex PCB type) mounted to the case.
Spindle motors and bearings are generally not the item that fails on
a drive these days. It is usually the spindle drivers.

Yes, dumbfuck... even the "barras" main cooling requisite was the
driver/controller PCB itself (still is), not the platter box/drive
case, whichever one likes to refer to it as.

Totally relevant, you retarded fuck. A rubber isolated drive
conducts NO heat the "bay stack".
You are one clueless bastard, and I have succeeded in showing folks
reading this thread that fact, and I will cease responding to your dim
witted ass presently.

I never mentioned any such product. You are confusing me with
I told the person looking at it that it does work to cool a drive.
I never said anything about whether or not it was neccessary.
Nor did I say that I "liked it".

Taking heat away from any portion of the drive's case will
effectively reduce the entire drive's temperature, short of the PCB,
which is typically not conduction cooled via the case. In fact, it is
generally isolated from it as the case and spindle motor run hotter
than the PCB.
The whole idea of the product is conduction cooling.
Yes, it would.
Sure it would. Just not the PCB assembly.
It is also pure aluminum, which WILL conduct heat away from it's
Yes, but not all cases manage air flow correctly.

My AMD 64 X2 runs very cool as well.
My PCIx card runs at 35C at the GPU, and the CPU runs at 38C in a
80F environ. They get hotter when I run 3D games like Scorched Earth
3D or BFII. Then the CPU heats up to 50 or so max, and the GPU hardly
misses a beat, pegging 39.
The new AMDs are far cooler than my MP dual mobo was. They ran at
140F when I ran intensive apps or games. They also ran that way when
they ran two instances of a distributed process like Seti or protein
I am 100% satisfied with my case temps, and even run the thing open
often. I hardly notice the digital noise in my TV when I do so I am
