What is the normal operating temp for a 2007 iMac

just wondering what it should be around since i never cleaned it out yet.
heres some numbers
current room temp 82C
CPU a Heatsink 53C
CPU core 1 52C
core 2 54C
display 49C
graphics processor chip 1 63C
graphics proessor heatsick 1 64C
graphics prosessor temp D 68C
HDD bay 1 50C
main logic board 53C
optical drive 43C
power supply position 1 80C
smart disk wdc wd3200aajs-40 49C
wireless module 58C

As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a
SMC RESET

Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.

What are the normal operating temps for a G5 Quad Core Power Mac Tower?

I asked this within another thread but I am afraid it will get buried and think it deserves its own item.
I just downloaded Temperature Monitor and have been looking at the data. I have no idea how to interpret the figures and there are no listings of specified upper and lower limits even though there is an area where those numbers should go.
The numbers are constantly in flux, going up and down a degree or two but here is a recent example from a screenshot taken while I was running WORD (but not working on any document), Terminal, Apple Mail, Firefox (two windows open), Temperature Monitor, Preview, Dashboard and Finder:
Air Tunnel 99.5 degrees F
Air Tunnel Heatsink 92.8 degrees F
CPU A Core 1 Diode 107.5 degrees F
CPU A Core 2 Diode 107.8 degrees F
CPU B Core 1 Diode 108.0 degrees F
CPU B Core 2 Diode 111.5 degrees F
Drive Bay 87.8 degrees F
Graphics processor chip 131.0 degrees F
Main Logic Board Air Inlet --- (this is always missing)
Main Logic Board Backside 108.7 degrees F
Memory Controller Diode 133.9 degrees F
SMART Disk WDC WD2500JS-41M.... 104.0 degrees F.
The icon for the program, in the dock, gives me an ever changing number that is perhaps an overall reading - an average. Right now the number is 106.4 degrees F (taken some minutes after the screenshot providing the above data). Always in flux.
Do any of these temps look alarming? And HOW and WHERE do I find out what the temperatures SHOULD be?
PS I have APPLE RAM.

If you want to find out whether a sensor value is within normal limits, please select the menu item Window > Show Overview (or press Apple+1) and look for the limits in the third and fourth column of the sensor table. They contain the known official limits Apple has specified for readings acquired at the given sensor locations. If no limit is given in the table, this either means that it does not make sense to specify a limit for this particular sensor (e.g. the battery capacity should not have limits), or Apple hasn't published any specifications for this sensor.
Note that all up-to-date Macintosh models automatically shut down or enter sleep mode if one of the readings exceeds a critical limit. For this reason it is impossible that your computer can be damaged in an overtemperature condition.

What is a normal operating temp for MBP

My MBP (2.33GHz/3GB RAM) is huffing and puffing when I'm running a lot of apps. I installed a temp widget and its been above 160 farenheit and is typically at 130-140 degrees normally. This strikes me as a bit high. I've seen a few rumblings of heat issues, but nothing concrete nor anything indicating what a normal temp is.
thoughts, resources, ideas?
Thanks
MBP Mac OS X (10.4.10)

The range of temperature will probably be from around 30ºC (sleeping) to 85ºC depending upon CPU load. Thermal shut-off should occur at 125ºC. The fans idle at 2,000 RPM and have a maximum speed of 6,000 RPM. The fans' speed will increase as the core temperature rises in order to cool the computer.
Your computer seems to be operating within nominal parameters.

What is the "normal" operating tempature for a 1025-nr

I have a dv-7 1025-nr, and the top of it seems to hotter than it should be. I can hear the fan running and it seems to be running at its highest rpm However it just not keeping it cool enough I actually have the back of the laptop propped up so it will cool better. Also, what software do I need to get to read the tempature sensors?
Thanks
windows 7 x64

The laptop is of the age where it is likely time to open it up and clean out around the fan and replace the thermal compound with new.

Normal Operating Temp. for MBP running windows

Hi,
Does anybody know what the normal operating temperature for a mbp 2.5, running xp professional is?
The load is just normal office stuff, eclipse, tomcat, explorer..
I've installed speedfan to monitor the temp, it normally stays around 61 C
This seems high to me.
Anybody know what the official normal temp is.
Cheers....

I found temps were generally much higher when running windows. The fans kicked in much later than i would have liked. I was running vista not xp.
I found if i ran smcFanControl (set to 3000rpm) in OS X then reboot into windows the fans would retain the new settings and windows would run a lot cooler.
Hope it helps a bit.

Normal operating temps. for MacPro2,1, 3GHz Xeon, 8 core?

Does anyone know where I can find a chart or a list of normal operating temps. for the MacPro2,1, 3GHz Xeon, 8 core?
I can't seem to find anything online. Thanks for any help.

I think Hardware Monitor would tell you what and may have a database.
Intel obviously. Just look up the processor for TCASE and TJMAX
More interested in what YOURS are and FBDIMM temps are often the most helpful.
Considering how many people are upgrading theirs to X5355s, redoing thermal paste, there is a lot of info out there.

HT2101 What's the lowest operating temperature for iPhone 4S?

My phone turned off by itself & couldn't turned it On while I was out for trekking & temperature was -40 oC. I use a leather casing for my iPhone. I was out of contact with my family during that time. Surprisingly when I turned it On upon reaching home it still showed 40% charged status. What's the lowest operating temperature for iPhone 4S?

A Google search is your friend. This was the first hit with a search for "iPhone 4S specs".
http://www.apple.com/lae/iphone-4s/specs/
Operating temperature: 32° to 95° F (0° to 35° C)
Nonoperating temperature: -4° to 113° F (-20° to 45° C)
Relative humidity: 5% to 95% noncondensing
Maximum operating altitude: 10,000 feet (3000 m)

What is the best 500GB HDD for a 2007 macbook pro

what is the best 500GB HDD for a 2007 macbook pro. This is a pre unibody machine.
I am upgrading at the minute and can't make my mind up. I need a 7200rpm drive, but have heard some stories concerning overheating etc.
These are the drives I am looking at: Seagate Momentus, Hitachi Travelstar and Western Digital all 500GB, running at 7200rpm.

If you haven't already, you might look a the user comments at http://www.newegg.com on those hard drives. If you don't get other comments here, you might post in the MBP discussion (this is the iMac discussion) at https://discussions.apple.com/community/notebooks/macbook_pro

What is a normal operating temperature for a 15" MBP 2.33 duel?

i know this has been beaten to death, but i never can find what is considered to be a "normal operating temperature" for the MBP.
mac book pro Mac OS X (10.4.8)

An MBP C2D should operate from 50ºC through to about 85ºC. I find mine averages in the low 50's however I don't do a lot on it. Anything that really requires processing gets done on my Mac Pro. It really comes down to how hard, or not, you push the processors.
Comparitively I find that it generally runs cooler than the PowerBook G4 1.25GHz it replaced however it does get hotter under maximum load. It just comes down to what you do with your MBP. You've basically asked "how long is a piece of string".

What is the normal gaming temp of the new NVidia GeForce 750m? Mine is running at like 75c playing DAYZ on bootcamp?? Is this safe?

I'm concerned =/
Running on 2880x1800, the game runs smooth, but it gets really warm and the fan gets loud =/
checked it with speedfan, 75c =/
playing plugged into the charger, and running windows 7 ultimate. 64bit
thanks for the input

860M is a good GPU. I would like to know if this is one of your first gaming laptops?
My suggestions -
1) Play games at 1080p (max). The GPU you have cannot handle games at a resolution more than that.
2) In most games, you will have to know the graphical settings and turn down the most demanding settings.
(such as Ambient Occlusion, Post Processing FX, Tessellation etc,) You need to learn what these effects are how they affect your system.
3) Take care of your system, like benchmark a game before playing to prevent overheating.
4) Make sure the game you are trying to play is stable and optimized (otherwise you wont get the performance you want)
5) Change desktop resolution to 1080p, adjust font and size sliders in Windows settings for optimal experience.
If you want specific advice for an issue, let me know. Have a nice day.

lI would trust these figures more than Speccy.
They appear to be in a normal range and as a precaution please review this article on reducing heat.
