Hard Drive Temperature in 50-53C range?

Griff. et al:

I'm using version 3.1 of Hardware Monitor.
My screen shows the following:
ODD temp.
HD temp.
NB Ambient temp.
NB Temp.
GPU Ambient temp.
GPU Temp.
Incoming Air temp.
CPU temp.
CPU voltage
CPU current
and fan speeds for ODD, CPU, and HDD.
When I first updated to current version of Hardware Monitor and noticed these different sensors, I e-mailed them, I believe in Germany and their response was these are Apple designations and should check with Apple to find out what they mean but I'll try and go back to their e-mail response and double check the message. Anyway, my NB temp., whatever it means, runs about 76C and the NB Ambient about 63C. Do any of the temperatures you and others have run this high? Oh, I assume this is the U.S. version of Hardware Monitor.

Griff.:

Maybe maybe your memory controller ambient is my NB ambient and your memory controller temp. is my NB temp. Your optical drive temp. may be my ODD temp. But you have optical drive temp and one more read out than I do. I only have eight whereas you have 9. Interesting!

Incoming air temp 41c... is this machine over a radiator??? :S

Normal incoming is room temp 22-26/28 c

Thats weird...

Normal! Don't worry!

It may indeed be normal. Then mine is abnormally low: 27.5C.

But then I live in Canada where temperatures are low everywhere :o)

In fact every morning I have to chip the ice off my iMac to get it started.(kidding).

I have 1.5gb of memory.
My NB Temp is now at 75.4C. This is the highest it has been and it seems to stay within a relatively narrow range. Mr next highest is NB Ambient which runs around 60-63C. My HD seems to stay around 46. My CPU around 56 and my incoming air will vary. Right now it is about 33C. My computer has been on for a number of hours. My CPU amps is about 1.52 and the processor is at the highest. If I change it to automatice the amps. drop to about 0.8.

I wish I had that problem. =D With the ice OR the low computer temperatures.

Initially, my NB Temp was hovering around 82C - quite hot I might say (how is it we're talking Celsius here when Fahrenheit is much more relevant???). Anyhow, over the past 10 days the temperature has been more like 65 - 72C. Perhaps this new machine has been going through a break-in period??? Pure speculation on my part.

At the moment my CPU temp is 53C, HD temp is 39C, incoming air 30C, NB temp 71C, and the fans are very quiet.

As long as this machine keeps purring along I'm not going to concern myself about the temperature fluctuations or levels.

Sometimes the more we know, the less we know! 😟

how is it we're talking Celsius here when Fahrenheit is much more relevant???

Why "more relevant"???? The vast majority of the world's population uses Celsius, and its the internationally accepted system. This is an international board. Only two of the eleven or twelve posters in this thread indicate that they come from the one place in the world where the old German system still clings on.

Celsius is also the system used in almost all technical and scientific arenas, regardles of location. Seems like a "no brainer" to me. Celsius is the appropriate system to use in a discussion of this kind. 😉

Well put. I stand corrected. I guess I'm being a bit too American-centric for the likes of these forums. Time to dust off my pocket converter! 😉

I remember spending a year in Australia. Constantly running the celsius, kilometer, litre conversions in my brain. Confusion would be an understatement.

I just found out an interesting fact. I checked in the Energy Saver Preference Pane and found that my Processor speed had been set to "Automatic" rather than "Highest." I set it to highest and watched the temperatures. They immediately started to climb. The processor ramped from 45°C to 57° in a matter of about three minutes. I could see the digital counter start to change the moment I closed System Preferences.

I guess this would explain why my temperatures have been consistently low up to now.

So, I guess there is a trade off between high temperatures and high speeds when you set the processor to go at full speed all the time.

Or just load the dashboard widget. 🙂

I guess this would explain why my temperatures have
been consistently low up to now.

I haven't noticed any significant difference in my temp. readings between Automatic and Highest processor settings. Were you running any processor-intensive apps? I leave my setting at "highest", yet fan sound remains quiet.

Hello everyone!

I've been monitoring my iMac's HD temps using
Temperature Monitor. When my iMac is busy (by busy, I
mean browsing the internet, typing Word
documents/making Keynote presentations or watching a
DVD), HD temps can get into the 50-53 degrees Celsius
range. The average would be around 51.5 C. I'm a
little worried since my HD's maximum operating
temperature is rated at 55 C. Are other users getting
the same temperature?

Mine been like that since I bought it may no what I'm doing. The fan speeds just go up or down to maintain it. Only time its different is when it just wakes up. This is fine for the HD. There's a lot of misunderstanding about the 55 C limit. it refers to the ambiant tempeture, not the drive tempeture. There are real things to worry about in life, this aint one of them.
