Ambient sensor help

[Steve1812]

Just started to play with Macs Fan Control.

To what does the ambient temperature refer- is the room temperature?
My imac has been on all morning in a room that is at 23deg C.
The software says the Ambient is 8 deg C and fan speed 1392rpm - normal imac fan speed.

So again, what is the Ambient temp referring.

iMac is the latest 2012, 20 inch version.
Im running the software as a trial as I think it will help sort a diagnosis problem on a 2009 imac thats coming to me.

Please copy technical information from the About dialog
A screenshot of main window would be also great
Thanks

[Steve1812]

Just want to know what the Ambient refers to - is it the outside air temp, though as you can see it shows 10 deg C in a room at 25 deg C - very warm day here in the UK near Manchester.

[Steven]

Ambient usually tells about air temperature in the iMac case. 10 is really strange

Please press the button "Copy technical info" and share the output

[Steve1812]

As requested here is the techie bit.

Steve

ps current room temp 21 degC and ambient reads 5 deg C.

[Steve1812]

Think I forgot/ or failed to attacment the word dock of techie stuff so here it is pasted in.

[Steven]

thank you, it looks like this value is not correct on imac 13,1, just checked another iMac.
What is min, max value for Ambient on your iMac? (approx)

[Steve1812]

Excuse my understanding but how do I find the min/max ambient for my iMac?

Is this part of your software or new imacs specification in general?

Steve

[Steven]

Just empirical, visually. Does it change actually?

[Steve1812]

Came across a thread regarding iStat - a similar thing I believe and several people with new 2012 iMacs have an ambient reading of around 9 degrees - their gurus suggest its a programme thing making the software incompatible as far as ambient readings go.

Steve

ps I have just installed the same version of Macs Fan Control 1.1.0 (imac13,1) on to a 2008 intel iMac with Mountain Lion and the ambient there is 25 deg C - room temp is around 24 deg C.

Hhhmmmm

[Steve1812]

me again, over the last hour the ambient has flicked from 9 degC to 7 deg C and back again.

As far as I can tell the room has stayed at a constant temp too.

Steve

[Steven]

It looks like this sensor should be removed when running MFC on iMac13,1, as its value is not correct (9 deg C is not possible inside a computer)

[Steve1812]

Will you be able to correct this in a later version of this overall excellent bit of software?

Steve

[Steven]

Well, шt's very simple to remove this sensor, for now you can simply ignore its value. Currently need some more data to remove it - ithere're only 2 computers with the same issue. If it's systematic - the sensor will be removed.

[Steven]

Fixed in 1.1.1
