Underside hard drive coolers bad for hard drives

Now....I just remembered something. A while ago, I had a problem with
my WD hard drive. I sent in for RMA. No problem with that.

Now, I have to also send in my Seagate HD as well due to many allocated
bad sectors.

What seems to be the common link between these two drives is that I used
a cheap hard drive cooler, the one you fit on the underside of a hard
drive.

Could it be possible that the cooler is causing vibration issues and
this is causing the hard drive to exhibit problems over time?

No, that shouldnt produce reallocated sectors.

It might well have been the problem with the seek error rate and the Hardware ECC Recovered.

Possible. Another common link would be the PSU.
Rough handling can cause the same problem.

The circuit broad of hard disks is always on the under-side.
I think you should cool the upper side....

Actually you should cool the underside because the board is there.
Also the underside typically exposes part of the aluminum body,
whilc the top side does not.

Thanks. But doing so would blow dust directly over the circuit board.
Also, some hard disks have a slid under the disk to protect their
circuit boards.

The dus does only matter insofar as it creates thermal insulation.
That is why you should clean your computer occasionally.

Historically, yes. I have not seen any of these for quite a while.

The part of a hard disk that usually fails from overheating
is the circuit board, so you want to cool it as directly as
possible. Also, all the mechanical components are mounted
on the aluminum chassis. The top cover is only a shell.
Air flow over the cover will have some cooling effect, but
way less than air flow over the bottom. I have yet to see
dust build up on a hard drive. Dust tends to build up on
edges, rather than flat surfaces. That's why fan blades and
heatsink fins collect dust.

Don't forget the head driver chips..

If your pC has good air circulation you don't need any dedicated cooling
for the HDDs at all. I've never used them and have never had issues with
heat and HDDs either. I have 3 HDDs in my main PC and heat is just not
a problem because that PC has good air circulation. People with loads of
fans in their cases are just attacking the issue from the wrong angle
and is overkill.

First thing to do when getting a new case is get one with good
ventilation on the front, next cut out those stupid exhaust mesh grills
on the back of the case. Those impede air flow greatly and cause noise
due to turbulence. Do those two things when getting a new case and heat
will not be an issue. Problem with many of today's cases on the market
is that they have stupid doors on the front so there is no ventilation.
Doors are just a bad idea all around. Who wants to have to open a door
every time you want to change the cd in the drive? Not me, I avoid cases
with doors like the plague.
