Two HDDs close together=Bad

I have five HDDs in my main PC, all one on top of each other.
There is only one 120mm fan (at the front) blowing across them, but it seems to be alright.

Someone mentioned the other day that the fly height of the heads above the platters is about 1/2000th the thickness of a human fingerprint. Running your drive upside down in an attempt to keep it cool just doesn't seem like the right approach, somehow

Hard drives better not care which way they're running. Dell and big companies like that mount drives vertically all the time.
And as for multiple orientations, think about portable MP3 players that have hard drives. I doubt that such devices have big "This end up" labels all over them.

I didn't say it was bad to mount them vertically, that's kosher. Read again

mechbgon is on crack. hard drives are designed to run with any of their flat surfaces down. Just dont go changing the orientation when it is on.

I believe that if you get face-down in enough HDD technical documentation, you'll find that there's a method to the madness

Wait, nm, I could be smokin' crack after all! :shocked: I was checking out the tech sheet for the Cheetah 15k.4 and they say you can mount them in any orientation (no, there's NO double meaning there ).

So maybe they've gotten past the this-side-UP thing. Sorry about that! Still not the right answer to drive cooling, though.

oh yeah?

::disgust::|:Q:frown::heart::brokenheart::beer::music::wine::lips::camera:

too lazy to do the other ones

a fan blowing over your drives will be fine cooling them

nothing like a load of crap after lunch... since there so many misconceptions being thrown around i'll just clear it up for you:

1) it doesn't matter how you mount the drive unless it's some weird position that will cause it to gyro. manufacturers use vc actuators instead of stepper motor actuators so knock yourself out, upside down right side up or on the side they're all legit.

2) the hottest part of a modern drive is the base casting along with the cover, mostly because of the air friction created by spinning platters.

3) no reason why you should have to actively cool a current gen. 7200 rpm drive in a bigger than mini-tower/desktop case with no extreme hot spots.

4) make sure the drive is mounted in the cage with at least 4 screws (2 on each side) that'll maximise the area of contact with the drive cage and help cooling.

and that note about bigfoots is irrelevant because they were 4000RPM drives.

Thanks for the info Mech & Album!
