normal hdd temp

[Red Squirrel]

This is crazy one of my HDDs is 157 degrees

Is this a normal temp for HDDs under high stress? (rebuilding raid + copying lot of files)


[root@borg ryan]# smartctl --all /dev/sda | grep -i temp

What's that in °C?

touch it, is it blazing?

 

[Red Squirrel]

Yeah don't want to pull it out, its in a raid array that's still rebuilding so it would delay it more. But, wouldn't like, the plastic melt at that temperature? Maybe I'm getting a wrong reading on that drive. The other temps make more sense though.

I did remember reading that article, but I'm sure there's such thing as TOO hot, and above boiling temperature would probably be considered too hot.

its 69 degress give or take a few. nothing earth shattering just try and get a fan on it for the time being.

 

[Red Squirrel]

It says Temperature_Celsius though, then 157... but guess that could still be wrong, as its probably just preset in smartctl to say that but it may be in F.

It's in a raid drive enclosure and that was my fear, that the cooling would not be as good. Though the fans that are on the case are not really that good, they don't turn fast enough even at full voltage. To force air through the HDD bays I have all fans set to suck air out of the case hopefully this will work ok in the long run. But knowing HDDs are not that heat sensitive its reassuring. And they're raided anyway so if one does fail then I have some time to replace it anyway.

If it was 157C you'd probably start to smell the circuit boards singe and the plastic melt .

 

[Red Squirrel]

Yeah kinda figured. Gives a whole new meaning to hot swap.

My internal SATA drives (500 GB) average about 32 C. {Celsius = C.}

lol it would be like sitting next to a bbq, u'd know.

still, kinda lousy enclosure.

 

[Red Squirrel]

This is the enclosures I have (2 of them, only one in use now)

I can feel cool air when I put my hand in front so it is going in ok, but when you got 4 drives in a high density setting like that guess the heat builds up faster then it can be cooled internally.

This is the temps now:

[root@borg postfix]# smartctl --all /dev/sda | grep -i temp
190 Airflow_Temperature_Cel 0x0022 065 062 045 Old_age Always - 35 (Lifetime Min/Max 23/38)
194 Temperature_Celsius 0x0022 035 038 000 Old_age Always - 35 (0 23 0 0)
[root@borg postfix]# smartctl --all /dev/sdb | grep -i temp
190 Airflow_Temperature_Cel 0x0022 075 073 000 Old_age Always - 25 (Lifetime Min/Max 16/27)
194 Temperature_Celsius 0x0022 074 073 000 Old_age Always - 26 (Lifetime Min/Max 16/29)
[root@borg postfix]# smartctl --all /dev/sdc | grep -i temp
190 Airflow_Temperature_Cel 0x0022 067 065 045 Old_age Always - 33 (Lifetime Min/Max 27/35)
194 Temperature_Celsius 0x0022 033 040 000 Old_age Always - 33 (0 22 0 0)
[root@borg postfix]# smartctl --all /dev/sdd | grep -i temp
194 Temperature_Celsius 0x0002 166 166 000 Old_age Always - 36 (Lifetime Min/Max 19/38)
[root@borg postfix]#


I'm also wondering, maybe its actually the last number that I should be looking at.

ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE

I assume VALUE is right one, but maybe its RAW_VALUE that is the real temp? Can someone shed light on that? If its the last one, then the readings arn't so bad after all.

I believe the number following "Always" is the temp number in C that you are concerned with.

 

[Red Squirrel]

ohhh ok, so yeah guess 35 aint too bad for a HDD then. Guessing the 23/38 is the range it should stay within for best life time?
