Harddrive noise and heat

[Guest]

Archived from groups: 24hoursupport.helpdesk,alt.comp.hardware.overclocking,alt.comp.hardware.overclocking.amd,alt.comp.periphs.mainboard.abit (More info?)

Hi,

Are there any harddrives that are known for being quiet? And any that are
known for operating at a low(er) temperature, and any that are preferably
both?.

I have 2 seagate barracuda drives in my box and they are the noisiest
components in there. After the box has been on a while, they make a constant
deep humming noise that is very annoying and vibrates through the floor and
can be heard around the house.

Any one have any cheap and cheerful tips on how to eliminate this noise, Ive
found that if i press against the box case, this sound disappears, but
returns when I let go. I have eliminated most of the noise in my machine
with silent psu etc, but this harddrive noise sort of defeats the purpose.
Do hard druves get noisier the hotter they get?

Thanks for any help.

tighten the screws to the hard drive to case.
if you chose ATA 133 or higher , the noise gets lower, which is new
technology hard drive.

Hi,
Samsung is the best bang for the buck and VERY quiet.
NewEgg has the best deals and service.
See reviews for the 160gig here
http://secure.newegg.com/app/CustratingReview.asp?DEPA=0&item=22-152-011
Or the 120gig here
http://www.newegg.com/app/ViewProductDesc.asp?description=22-152-013&depa=0
Plus Samsung has 3 year warranty.
Over the last couple of years I have changed out all my drives to Samsung.
40gig
80gig
120gig
All are very quiet and not one problem.

I have used Quantum, WestDig, Fujitsu, IBM, and Maxtor.
Samsung is the quietest I have used.

Slower and smaller are quieter and generate less heat. If reducing heat
and noise is more important than performance and capacity, try a 2.5"
notebook hard drive.

From the horrendous noise problem you describe, are your sure your drives
aren't failing B^)
Also, judging from your description, placing your system case on a rubber
pad and gluing similar pads to the sides of your system cases should go a
long way toward damping the vibrations.

Well i'm using maxtor disks in my server which is on 24/7 and my desktop
which gets a lot of HDD intensive apps thrown at it. They run near-silently,
i can't hear them over my volt modded CPU and case fans, and run at 38.5
degrees.
I used to use seagate drives and they were noisier, not sure about the newer
ones though.

This sounds like its a bad mounting in the case rather than the drives
themselves.
Cheap case?
Not screwed in right?
Only one/two screws?
No rubber mounts??

Without checking, I can't be certain, but I thought the latest
barracudas were one of the quietest drives out there and are recommended
for quiet applications ??

Thanks for all you replies. The case is an Antec 1080amg, I think its an ok
case (it cost a lot!). The hard drives are actually 2 seagate barracuda 3
ata 100 40 gb, perhaps these are a little noisier than the newer models??.

Otherwise they are screwed in tight all 4 screws, only thing I dont have is
rubber mounts, ill look into this.

thanks again everyone.

Sometimes even if you screw them in tight, the HDD rack itself can make
noise when it vibrates, it can also make the case vibrate and make noise.

If you can get some rubber grommets and place them around the HDD
screw-holes, they reduce vibration, and stop any noise being generated
between the drive and the drive rack.

If you don't have grommets available, try some rubber washers.

Since you mentioned noise and heat, others have said in the past that
rubber mounts cut down the conduction of heat from the drive to the
cage and this can be a substantial part of the cooling for drives,
unless you add fans and that adds more noise...
Sometimes it seems like you just can't win.

I've noticed my old 60, 100 maxtor drives were dead quiet when I
bought them, but they're getting noisy three years later. Some
noticeable whine these days. These were 5400 drives, too. I used a
real old 11G maxtor to test a new system to make sure the new
components all worked, and it was horrible to listen to. xtreme whine.
I should toss it out. I thought it was quiet when I bought it compared
to an old 350M.

Currently using some 250G western digitals, and they are almost
silent. Some people complain of a very high pitched whine with them,
but mine seem to be ok or my hearing don't go that far.

You should put a fan or strong case cooling on any 7200 hard drive
reguardless of maker, so slight differences in heat shouldn't really
be an issue. Even the coldest ones need cooling.

Hitachi drives run faster, quieter and cooler.

Coincidence time.... that's what I'm using on this machine now.
Without opening it up to check...... this has a removable drive caddy
unit yes? It could very well be the whole caddy itself that's vibrating
(is the clamping lever all the way in??)
Take the whole thing out run the machine with the caddy on something
like a piece of soft cardboard. Should be easy to find out the source of
the prob them (although its probable the noise will have gone now)

As an aside, someone else mentioned rubber mounts not transferring heat.
Even with the drives screwed directly into the metal of the case, they
will still get hot. The Antec has a mounting for a front case fan that
blows over the drive bays. You hardly need any air movement to
substantially cool these drives down.... but with none at all, you're
asking for problems. Get an 80mm quiet fan and run it slow.
Also, you don't have the two drives stacked right on top of each other
do you ?? this will really cook them. space them out. There's plenty of
room in that caddy!

I've read very good things about people who use some sort of elastic
chord instead of a normal screw mounting.

7200rpm drive = 120Hz vibrating noise of turning platters
5400 = 90Hz

this frequencies are both in Bass audio band ...
if you can hear it all arround, there is something also resonating:
the room, furniture .. etc ..

use some gommets under screws ... (can help also under case too)

True enough but there's a lot more going on than simply pure rotation of
the platters. For one, there's bearings, which can introduce noise of their
own (and lord knows what frequency that will be). Second, it's probably
being direct driven by a 9 pole brushless motor that's introducing multiple
vibrational pulses per rotation, not to mention potential vibration in the
windings themselves (and if it's a delta winding they're being activated
twice with opposite polarity), or their mounts.

I have just bought a Samsung Spinpoint after reading good reviews of it and
I can say it is considerably quieter than my Seagate Barra (Only 6 months
old) and I thought the Seagate was quiet.

I have a 20 Gb Maxtor that looks to have an airplain turbine spining on it
and also have a Maxtor 200Gb that is very silent (7200 rpm sata).

Zalman have a heatpipe passive HD cooler, that also comes with rubber
mounts for the drive. I only have one, and will be buying more for future
drives, cheaper and its better looking too than the fan'ed coolers.

Barracuda V were the first of the very quiet Seagate drives
from memory. The current model 7200.7 are almost as quiet. Some
people say they are slightly noiser, but others can't tell the
difference. I have the 7200.7 and find it silent in operation.

Maxtor, Hitachi/IBM, Seagate, and WD all make fluid bearing hard
drives, you just have to check the specs on the drive models.

Ok, you have lots of opinions.

Here is a fact:

Drives with Fluid Dynamic Bearings (FDB) are quieter than those without. At
least idling. Some drives seem to make a lot of noise seeking whilst
others don't.

Yes, it's a generalisation, but nevertheless if you take two similar drives,
one with and one without, the one with FDB will be quietest.

yes, sure, but if he can hear it all thru the house, that is gonna be

uh, thats really annoying; I resolved that irritatting problem with my

yes, but IMHO the frequencies to spread around IMHO would be of much
higher tone & not so strong ..

Well, not at easy to kill but higher frequencies bounce great. You ever try
to FIND where a high frequency tone is coming from?

I used to make a wedding night light activated 'alarm' that used a high
pitched tone and it was hell to find. hehe

First low. Now high. Make up your mind.

have to second what misfit said - the samsung spinpoint series (esp. the
S-ATA drives) are near silent. hitchis (formerly IBM) are also very quiet
in S-ATA iterations.

barracuda series (except perhaps the latest variants) were notorious for
their noise.
