I have 5 HDDs


WD 160GB WDC WD1600AAJS-00PSA0
32C - 38C

Seagate 250GB ST3250824SV
32C - 38C

WD 320GB WDC WD3200AAKS-00SBA0
31C - 38C

WD 500GB WDC WD5000AAKS-00TMA0
39C - 46C

Seagate 160GB [ Constant Torrenting] ST3160811AS
37C - 46C



All this temperature are in air cond Room temperature and the max is air con and fan off room


Question is why does my 500GB and 160GB hdd so hot even in air cond room
its at 39 in air cond room
my 500GB hdd is empty and its not running or what so ever..
but my 160GB is 24/7 Torrenting.

Can anyone clarify for me?

Thank You Very Much

And can anyone tell me is it normal to get those temperatures?
or i would say what is the normal temperature for HDD

Besides that why is my 500GB empty hdd hotted than the 160gb which is running non stop

my harddisk runs at around 40C averagely...

not to worry as long as it below 60c its ok.IMO the bigger the hdd the more heat it generates even in idle.plz correct me if im wrong here.

i use high cfm fan to blow the hdd so the temp will be <40c...

Just nice....

maybe because the 500gb hdd has more platter so it more torque to spin???

or the hdd is placed at a very bad area less air circulating @ airflow.just try adding a fan close to it and see whether there's changes in the hdd temp

mine 1 250GB got 1 'chiplak' 80mm fan blowing...around 38-40
but when no fan....up til 45....Zzzzzz

HDD temp depends on,
-circuit power efficiency
-spin rate (faster is hotter, 5400rpm and below rarely overheat as long as they're not kept in an insulated environment)
-platter count (more platters means more power to keep it spinning constantly. Also means more heads to move when seeking for data)

My guess is that the 500GB HDD has more platters than any other disk in your system, as only hard disks 750GB and above use perpendicular recording (which squeezes more data into a smaller area, allowing fewer platters to be used). Whereas your torrent disk is frequenltly seeking, so understandable that it would be hotter.

Hard disks should not be operated above 55C (high chance of premature failure, usually within a year or 2), best if keep within 35-45C. Too low a temp is also not good, though why exactly is not clear to me (read this in an report given by Google concerning their datacentres). Below 20C is will not do your hard disk any good, perhaps even some harm.

Actually SATA hdd will be hotter or PATA hdd will be hotter? (assume if both are 7200 rpm)

Thank You so much guys .. btw i do realize my first 3 hdds has a fan blowing it but the 500gb and the 160gb [torrenting] dont have any fan blowing it

but the max temperature it reaches is around 45C so i guess mine is working normal

btw anymore guys wanan share or compare thier hdd temperature as i search in google there is no post like this

both of my hdd running below 50ish C...since my WD is bloody HOT compared to my SEAGATE...

SEAGATE 36-38c WD 40-42c have a 92mm high CFM blowing fresh air to them

i got 2 hd in the cage, with fan blowing at them (35 & 39 degrees). 1 hd on top of the dvdwriter, with fan blowing at it too (43 degrees). By right the single hd should have the lowest temp among the 3, but its the highest. '

Last time in aircon room, all the hd had average temps of 30. Wondering why yours cannot go below 30.

well easy ambiance temp fren...its impossible to hdd temp same as ur room temp.it'll be slightly higer@ few C's more la.BTW if ur hdd temp is too low also not that good for its health.Basicly it needs around 30+C-40+C but <50C..
IMO

My WD 250GB around 50c. I put a Vizo HDD Fan and it is around 46c when idle.

Yes, SATA is a little hotter than IDE/PATA. Partly because the hard disk is able to handle more I/O requests (no need to take turns with another HDD sharing the same cable). Partly also because SATA uses a much much higher signaling frequency, so no surprise that the circuit takes more power. But when I say more power, its like only 1-3W more, so unlikely you can tell the difference in temp.

I still can't find that report done by Google on their datacentre HDDs. Think I read it in the newspaper. Basically it says that if temp is too high OR too low, HDD failure rate increases. The ideal range is 30-40C. Below 20C and above 50C is highly unadvisable.

w0ot.. hdd temp discussion eh??

got question here.. does the software monitoring hdd temp accurate?

can rely on em'?

Its probably not that accurate, but it can't be more than 5C off. Which is good enough already..come on, you don't overclock hard disks now...

PS: It was possible to 'overclock' hard disks long ago by inreasing the spindle rate, but current 7200rpm are already running at their limit..any faster and they fail rapidly..

My harddisk is about 41 degrees when i have it blown by the intake fan at room temp of 22 degrees

The same time i used a HDD cooler and the temperature shot up to about 47 degrees... what a disappointment lol...

Btw the harddisk i am using is on my sig...

hehe all my hdd jus check 35C..all blow with SS stock fan..no air con room

mine :

150gb raptor 10k rpm
250gb 7200rpm
320gb 7200rpm
40gb 5400rpm

dunno if the readin not accurate..using everest to read it

nice temperature there.no wonder look at ur case

good airflow case is very important

Your temp is seriously abnormal for a room temp at 22'. Probably you need to increase the air flow in ur case.

My room temp is around 27' (Air Cond). My HDD only at 29'c.

I dont know why bro.. well i am putting in from of my intake fan... and seriously, i know about intake and exhaust wind flow dynamics and all else is fine besides my hdd. I am not sure though whether its just the make of the harddisk that gives me 41 degrees. Because as i know, the normal operating temp for western digital hdd is around 0-55 degrees celcius.

By the way, my casing chassis doesnt support fans that hit the 2000rpm mark and above, the vibration caused by the fan... bleh so i am limited with my cooling capabilites... unless u know la:P water cooling

using mine maxtor 40gb
always keep at 26 degree to 33 degree.

in air con room i presume?

NO air cond = 30-33C loh.
In Air cond = 26-30C

ermm duhhh 40gb dun emits that much heat i guess like >100gb

-.-....duno...
Mine HDD left 1.5GB le..

WD 80GB Hardisk [ 34-36 celcius ]
Maxtor 160GB Hardisk [ 36-38 celcius ]

Western Digital seems like very fast to get hot when intensive disk usage, while maxtor not.

-pWs-

Hard to say. Hard disk temp sensors are even more screwed than other sensors. Had a few HDD report 16C in a air con room that was only 20C at the lowest. But anyway, for hard disks temp don't need to be precise, even if its off by 5C a readings of 20-40C should mean that the HDD is within very safe temps. No benefit to having the hard disk at super low temps, in fact, some report that the hard disk may even fail at too low a temp (sub-zero).

for me as long as Xcross the 50ish C enuff edi....

so,just wanna ask,what is the ideal temperature for the hdd,to prevent it from damage?

Mentioned already, about 20-40C (if you're checking with software). Hard disk should not feel hotter than your forehead. Too cold le, hard to say. If the hard disk is just aircooled and room temp isn't so cold that you can be naked for a few hours without shivering, then it will never get too cold.

ambient 29-30°C (no aircon). HDD idle 34°C. Load forgot.
stock CM fan.

Well, an hard disk has a stated operating temperature in their specifications for a reason. IMO, as long your hard disk stays within the 30-late 40s should be just fine.. nothing over 48 degrees is advisable.

isn't HDD cooler will really cool down the temp...coz almost all the hdd cooler are just come wiv a fan blow at the bottom side...

i dun recommend to use a HDD cooler, as the vibration from the fan may bring damage to the HDD. Better just install a 12cm/8cm fan at the front of the HDD and blow the cool air to the hdd.

Even a slow-medium speed 80mm fan blowing across is enough to keep up to 2 HDD within safe temps. No need for those HDD coolers which blow from underneath; they have terrible airflow anyway. More than 2 HDD may need slightly more powerful fans, but from my experience a slow 120mm fan can keep more than 4 HDD cool enough, which is really the most amount of HDD most of us might have.

this is the results i get from one of my HDD test(primary). do i need to replace a new HDD ?

http://www.hddstatus.com/hdrepanalysis.php

i have 3 of them and 3 of the HDD are at temperature 48 - 53
what should i do to cool them off cus i 24 hours on the pc xD

need serious advise cus my system already crash few times and each times it crash it cannot detect the primary hdd

my WD 500Gb green power max 37C with a chiplak fan 90mm

Wow all your temps are way lower than mine.
Mine is about 60+ to 70+.
Just bought a 8cm fan today and should I blow directly at it or pependicular to the hdd?
Now is blowing across the bottom part of my 160gb hdd but still I got 60+ at load.

my 320gb runs at 34c and my other 250gb runs at 32c.. Hdd are quite durable actually.. My old laptop hdd runs at 60c when playing game cuz the heat from the GPU and CPU can't escape.. So u don't have to worry about it much..

what is the effect if hard disk run under long hot temp? how high can a hdd support

yup, i also interested to know about it.....

Specs taken out from WD Caviar Black...

Temperature (Metric)
Operating -0° C to 60° C
Non-operating -40° C to 70° C

check the specs of ur hdd... max operating temperature is normally around 60C..

mine seagate 500gb 40C... no aircond

26°C ~ 60°C

must have atleast 26 deg cel to keep the mechanical + oil functioning

My temp using everest to detect it.. (no air-con)

WD 80GB = 35°C (use to run window)
Seagate 1TB = 39°C (24/7 torrent-ing/backup)

All HDD with fan blowing it... o.O

wow, a reply one year too late?!

anyways, the airflow within the casing is important to keep the temperature lower.

something between 40-60 C is fine.

My WD Caviar Blue 320GB with Coolermaster 120MM 90CFM fan - Max. 40 degree celcius, the lowest temp ever recorded - 30 degree celcius. Without fan - Max. 45 degree celcius

my seagate barracuda 500GB working at 36c at room tempreture

mine... around 26°C up to 40°C (maximum)... no aircond
