Harddisk temperature thread

Hi,

i've made the experience that my hardisk is getting really hot under linux compared to windows.
Therefore i'd like to start a thread, for collecting your average/min/max (whatever you can measure) harddisk temperatures. Please also post your harrdisk type.

Here's my data:

FUJITSU MHZ2320BH G2 [2.5-Inch, 5400 RPM, SATA]
(Lenovo N500 laptop)
Windows: during long usage not more than 46°C
Linux: 2 minutes after boot: already 50°C (up to 52°C)

Also by playing around i was not able to make it as cool as under windows. The harddisk is layed out for an ambient temperature of 5°C to 55°C.

IC25N020ATCS04-0 [should be a IBM Travelstar 20GB 4200RPM 2MB Buffer 2.5" IDE]
(Compaq evo n610c)
Linux: up to 52°C
Windows: no longer installed, but my left hand never felt that much heat as under linux.

Re: Harddisk temperature thread

I'm not quite sure 'collecting' other people's data is a good way to find out about your own problem. My guess is your problem - if there is a problem to begin with - has to do with more intensive disk usage or a higher overall temperature.

To begin with your measurement circumstances are different - your Windows data is after long-time use - which might mean the system has been running idle - and your Linux data is a few minutes after bootup, which means there has been intensive disk usage.

I would perform reliable readings before hastily concluding you have a problem. Collect data, perform various readings - on both systems, under similar circumstances - and try to discover patterns.

For what it's worth, laptop drives always run hot. My AMD laptop would routinely run at like 60 °C (it was a crappy Fujitsu that tried to die on me before I trashed it myself tongue). My server (a P180 with a few fans running at low speed) returns the following temperatures:

# hddtemp /dev/sd{a,b}
/dev/sda: SAMSUNG HM500LI: 25°C
/dev/sdb: WDC WD10EACS-65D6B0: 27°C

Purely informative wink.

Re: Harddisk temperature thread

here's my temps

/dev/sda: ST3750330AS: 23°C
/dev/sdb: WDC WD1001FALS-00J7B1: 26°C
/dev/sdc: WDC WD1001FALS-00J7B1: 27°C

the first drive is a seagate 750gb 7200.11, the other two are 1TB WD black editions

edit// here's my cpu and mobo temps, may give an idea to rough guess ambient temps. I'm running a Phenom II X4 955 on an asus M4A79T, so i'm using the asus atk module to temps, not the k10 or k8 modules. so i'm hoping the asus readings are accurate

CPU Temperature:     +29.0°C  (high = +60.0°C, crit = +95.0°C)
MB Temperature:      +24.0°C  (high = +45.0°C, crit = +75.0°C)

also, i just checked my thermostat, it says its 20-21*C in here

Re: Harddisk temperature thread

Not to mention that in Arch the _user_ is responsible for tuning some power saving settings (unlike windows that some may automagically work but no one knows how exactly tongue )

Also the ambient temperature is a big factor, can change as much as 10ºC in my experience. Also like B says laptop hard drives tend to work at higher temperatures because there is no airflow to help remove the heat, even if you use one of those cooling pads you are removing the heat mostly by conduction (hard disk -> chassi/case -> airflow) instead of direct airflow.

Here I run my disk with no power saving whatsoever but it's winter here and it's colder but If I start moving stuff around the temperature will easily jump to above 50ºC.

Thinkpad T60.  Room temperature here is roughly 24°C.  I don't recall configuring anything which might reduce heat around the drive.

Re: Harddisk temperature thread

Ok, i should have mentioned that i had already measured quite thoroughly.

The Windows value is in fact a maximum value (46/47°C) which has never been topped so far, even under heavy disk usage. I measured for a long time with SpeedFan.

Under linux i already played excessively with hdparm. While with hdparm -B 128 the disk is constantly spinning down, i have an average temperature of 48/49°C (idle) with this setting, under load it increases. With hdparm -B 190 it's no longer spinning down but the temperature tend to be at least 2°C higher, the same up to hdparm -B 254 and also 255 (APM off).

For my old laptop the values also have to be corrected a bit, it's currently running with 53°C.

BTW, i don't want to say that this is a *real* problem. I'm just curious, and would be interested if there is a way to cool the harddisk somehow down (without hardware measures), hdparm didn't work so far for me. Also the -M and -S didn't made any difference.

Maybe you should play with cpu and gpu powersaving instead... As was mentioned, ambient temperature (and ambient inside your PC!) is a big factor.
Hard drive may be under load or may be idle. It's spindle may spin or may not. There are no a lot of modes of operation for hdd.

Re: Harddisk temperature thread

Fix 1: a little bit of airflow over the HDD reduces temp by over 10 C
Fix 2: My new 5400 "green" disk is alwasy between 25 and 40C. So new (slow 5400 RPM) drivers don't get so hot. Hitachi drives are often hot heads

Re: Harddisk temperature thread

Was looking for hd temp info, found this smile

Mine are very cool. The WD3200AAKS's are idle at the moment, the ST31500541AS is performing a zero fill with dcfldd using bs=64k. When idle, it too goes to 21°C.

stefan@bacchus ~ $ sudo hddtemp /dev/sd[abcd]
/dev/sda: ST31500541AS: 23°C
/dev/sdb: WDC WD3200AAKS-00B3A0: 21°C
/dev/sdc: WDC WD3200AAKS-00B3A0: 21°C
/dev/sdd: WDC WD3200AAKS-00B3A0: 21°C

In front of these disks are Nexus Real Silent casefans (the b/w ones) behind a dust filter.
Seems those fans help considerably. I estimate the room temperature at about 17~18 °C at the moment.

Topicstarter, reason for your drive to heat up some more is possibly due to the lack of power management, as some stated above me. Look into cpufreq utils to dynamicly clock your CPU and perhaps your GPU also supports such management.
The harddrive could be taking heat from those components.

Re: Harddisk temperature thread

/dev/sda: SAMSUNG SV8004H: 36°C
/dev/sdb: Maxtor 6Y080L0: 38°C
/dev/sdc: ST380815AS: 40°C

Ambient temp is about room temperature.

I just added a side intake fan (not the best placement) which dropped it down to this.  Previously it was about +7 C higher for each drive.  These drives are unfortunately very close together because one in particular is slightly oversized for the slot.  It gets a little hotter as a result, thus the need for the additional fan.
