What is a "normal" or "good" temperature?

Just wondering what are a "good", "normal" and "hot" temperatures. My white 2 GHz MB Core Duo runs at about 33 degrees celsius on average. It dosen't feel too hot. What other temperature are you guys seeing.
This is what I am using to mesure my Temperature. I like it because it shows in the menu bar. Is it acurate?
Thanks,

Hi all,
I'm getting two different values on the two fans (?) please someone look at the linked picture and you will see the right fan is at -1 value, even when the two cores are at full stress 100% load, and the left fan is way above 5000rpm, is that normal???
Here's the pic: http://www.ramirezinteractive.com/macbook/fancontrol.jpg
When is the other fan going to kick in??? Please let me know if this is normal or if I should take the computer to the Apple shop...
Best,
Pedro

What is the normal operation motherboard temperature

HP Pavilion t6250p Windows 7 Home Premium 64-bit no changes to OS
Motherboard is Pegatron Benicia (CPU 1)
Temperature runs 43-44 C or 110-112 F Is this normal?
This question was solved.
View Solution.

That is a normal motherboard temperature.
If you happened to live in Death Valley, CA and had no airconditioning it would be a quite bit higher.

What's a Normal Temparature and what should i use to mesure it?

I'm a little confused because i can't get a good temperature reading.
Right now my system has been idle for about an hour and these are the readings i get.
Core Center says my cpu is at 52C
Nvidia System utility says it's at 48C
(i'm actually a little surprised because i've seen it at around 60C and even 1C. I think it's been fixed since i installed the AMD CPU driver)
Core can't read my system temp because it keeps showing 1 or 2C
Nvidia system utility says it's at 35C
And the bios . . .
Well i can't get a good reading out of the bios because it keeps freezing when i look at the system monitor screen. (I think that's the only place where it freezes though)
So what's a normal system temp?
I think it's a little high for an idle system, but it doesn't get much higher when it's under load.
Maybe i didn't put enough termal paste.
Does anyone know why my bios is crashing? Does this happen to anyone else?
I'm having a multitude of problems and i'm more and more worried i got a defective board.
I have the latest bios for the MSI K8N NEO2 Plat. (BIOS Version 1.2)
I have Athlon 64, 3500+ (i've read in the sticky post that there are some problems with the bios and this CPU)

TruePower 380Watt PSU
can be due to a weak psu.
that one only got 18a 12v
from what i heard in here that would not be enough for me with my gfx card which uses less power.

Mbp normal variance in temperatures?

My Macbook pro (core duo 1.86ghz) has always been extremely hot to touch, but I never thought twice about it. About a week ago I installed coreduotemp to monitor the temperatures and noticed that it reaches 96c when the processor is under load (no 3d graphics, laptop on a wooden table in a cool air conditioned room). Some parts of the notebooks cover get so hot that when a workmate accidentally touched it he screamed.
Since we have a lot of Macbook pro's where I work, I took an identical (apart from a 2.16ghz processor) model and did a profile transfer to it. When both notebooks where under load the difference in temperature was was over over 30c (64c vs 96c)! There is also a huge difference in how hot the cover of the notebook gets. The new one gets hot too, but never so hot that you can't touch it.
I called our local retailers support service, and they said they have no guidelines regarding the issue, and can not take it in for repairs.
I found this pretty surprising, so I downloaded a 3d game (sourbraten or something like that) and tried running it so that there was some processor load on the background. The screen came full of black distortion within a few minutes.
I called Apples support, and they said there must be something wrong with the video card, and the laptop should be sent for repair...
As an engineer working with servers for a living, I find this pretty funny. The support person didn't find anything strange in the fact that one of the notebooks is running at about 80% higher temperature over ambient, he actually said that "temperatures around 100c are fully normal for a notebook". I understand quality control will have some margin in a matter like this, but the difference is just huge!
The main reason I'm still wondering about this despite my mbp being accepted for repair is that we have almost 100 Apple notebooks for our workers, and there are a lot of other employees complaining about the heat. It seems most of the ones complaining received their notebooks in the same batch as me. Do we have to try to get corruption on all of them before extreme temperatures are regarded to be non-normal?

Hi, and thanks for all the answers!
A funny thing happened before I left work. We received a box full of silly gifts from Intel, including a usb coffeecup heater. Well the heater really works, it keeps your coffee hot until you drink it (mine was really hot for over 20 minutes)!
What's even funnier is that the notebook under load was about as hot as the coffeecup heater...
The notebook, and the one I compared it to where both updated with the latest firmware, and all automatically available operating system updates.
I'm an IT engineer, mainly maintaining fairly high end servers. I have however toyed and built computers for well over 10 years, and have quite a bit of experience with them. For example having two fully identical computers next to each other with the same configuration and running 100% load on each should result in almost the same processor temperature. In this case the cooler computer had a faster processor which should actually mean it runs slightly hotter (though speed actually does not have a huge impact on processor temperature comparing to voltage).
So what could cause the differance in temperature? There are really only a few possibilities:
- The hotter ones processor does not get good contact with the cooler
- The hotter ones fan(s) is not running as fast to remove air from the case
- A fan is broken in the hotter notebook
There are small variances in heat output between identical processors, but the differance would only be a few degrees.
I can hear the fans in both computers when they are under load. The hotter ones fan is actually running at a clearly faster speed then the cooler ones. The only logical explanation is that the heatsink does not have good contact with the processor. Due to this it can't really dissipate the heat however fast it spins the fan, and the processor remains hot. This does not explain why the case is so much hotter too... :O
I read the link you have regarding Apples guidance to temperature, but they are not actually saying ANYTHING in that article. Actually they say more in the detailed specs page you can get on the notebook on apple.com (sales). There they mention what the ambient temperature for operation can be.
Now when I called Apples support, I was told it is fully normal for a macbook pro's processor to operate at 100c. However according to Intels specifications 100c is the maximum temperature the processor is allowed to reach under any condition (this is the highest max temp on any processor I have heard of by the way). So what apple is basically saying, is that it's perfectly normal for my processor to run hotter then Intels highest allowed temperature? To add to this my ambient temperature while testing was 21c (14c under the maximum temperature allowed for operation). So what would happen if the ambient temperature went up to 35 (which is not even an especially high temperature...)? The processors temperature would most probably raise to over 110C!
Just like Intel has a maximum operating temperature for it's processors, hardisk manufacturers have a maximum temperature for their hardisks operation. Having a case too hot to touch does not make me feel very confident that the hardisk is operating under a temperature within the manufacturers limits.
But still Apple believes this is ok untill your notebook get's so hot that everything on the display becomes corrupted! Also their page concerning the macbook pro's operating temperature does nothing else then try to convince you that it's normal that your notebook burns you!
Really makes me happy I got applecare
edit:
btw, thanks for the info on the hardware test. Unfortunately I already packed the notebook for repairs, so I can't try it. Will defiantly remember it for next time though!

What's the normal fan speed?

Hello, my fans have always been around 2000 rpm with both tiger and leopord, so I am wondering what is the normal range for fan speed when the computer is not running anything heavy.

So, I'm not crunching much at the moment; yet I have 133 F and 3906 rpm. However, that doesn't signify. It was flat on a wood table. Now, laptop; Room fan now on. That fan is the main thing. I read a great overview, will post link if I can find it, that air is like fluid dynamics: a MBP flat on a table in an air conditioned room (no fanned air movement) will run hotter than an MBP with space under, with a room fan, moving warmer air. Yah, no, really true.
Get freeware iStat Control 1.1 (1.2 soon): (http://www.islayer.com/), which will display fans' speed and temps in the menu bar, andmore, and make popcorn too, with the lavalamp thingee.
Then I use Fan Control, 1.2, freeware, and set it up a tiny bit just to be cool: " ... Do you think your MacBook (Pro) is running to hot? Give Fan Control a try then. Some MacBook (Pro) are just to hot for daylong use. Fan Control adjusts the minimum fan speed depending on the current CPU temperature. For safety, it leaves the original automatic fan speed control intact ..." Leopard Ready, yah.
http://www.lobotomo.com/products/FanControl/index.html
Both are preference panes in System preferences, which is very elegant, imho. And yes I have Leopard still shrinkwrapped. I will take a stab at it soon. Goodbye, cruel world (nah).

Is it normal with higher temperature when plug in with power adapter?

Hey guys, I am wondering if is normal that the computer is much more hotter when running with the power plug in, because the temperature is much more lower when running with battery.

I have the same issue exactly, i downloaded istat pro widget as it monitors the temperature and it tell you what is the temperature but now i am trying to find what is the normal temperate for mac book pro is i know when it is getting hot

What are the normal settings to connect to wifi?

I visited my friend over the weekend and her school required me to change my airport settings in order to connect to the internet. Ever since I got back, I have been unable to connect to my usual wifi source. If I can, it drops off after a few minutes. What are the normal settings to connect to wifi?

As a minimum, the following would be the "normal settings" to connect your Mac to an unsecured Wi-Fi network. These settings can all be found in System Preferences > Network > AirPort or Wi-Fi > Advanced
TCP/IP tab: Configure IPv4: Using DHCP
Proxies tab: Nothing should be checked on this tab, except the "Use Passive FTP Mode (PASV)" option.
Hardware tab: Configure: Manually
On the Wi-Fi tab, you may also want to delete any Preferred Networks that you are not using.

What in the name of Goodness have you done re: the full screen picture of Contacts on my iPhone? Sort it out Apple or I'm going back to Samsung, where maybe I should have stayed!

What in the name of Goodness have you done with the full screen picture of Contacts? How dare you just change it without so much as a bye or leave? This is NOT progress but a throwback to about 1997! I supposedly 'updated' to an iPhone two weeks ago. Should have stayed with Samsung I reckon. I am deeply unimpressed!

New MacPro: Good temperature Monitor Application for the nMP?

Can anyone suggest a good temperature monitoring application they have used for the new Mac Pro?
Thanks

I would recommend iStat Menus (http://bjango.com/mac/istatmenus/). I switched to it when I got the Mac Pro 2013 because Hardware Monitor doesn't work with the new Mac Pro. It's pretty good, although the history is only visual with graphs showing the evolution of the different sensors temperature. With Harware Monitor it was possible to read the temperature that were recorded at a certain point in time.

What are the normal Boot time?/Wake from sleep time? for MB?

Looking to buy a MacBook for my wife to replace her old Dell D-420. The Dell still works fine but takes forever to boot and to wake from hibernation. I was given an old iBook a few weeks ago and was amazed at how fast it woke from sleep mode (the boot times were pretty snappy too). So my question is. What is the "normal" wake from sleep time on a MacBook? How long does a cold boot take?
BTW: Steve isn't going to surprise us with an updated MacBook next week is he??
Thanks
Soon to be MacBook owner.

lancia is right- 56 second sound about right, my 2.0 GHz MacBook boots in about 49 seconds.
If you want your MacBook to boot up faster, you can reset the PRAM (parameter random access memory). What this does is that it resets all the devices it searches for when it starts up: forgets about them, literally
To do this, press down the command (the buttons next to the space bar) , option, P, and R keys at the same time when you turn on your MacBook. Press these keys until you hear the tone a second time. Make sure to do it quick, because after you hear the tone it won't work.
Hope this helps,
Wookams
To your BTW question:
Almost certainly not, but I still recommend waiting a couple months extra because Apple notebooks usually update themselves every 200 days or so. I was disappointed from learning this, but hey...

hello, this is a very normal value for a modern browser. it is impossible to reduce the memory footprint ten-fold as you'd like it...
in independent tests firefox has generally been found to be the lightest browser in regards to memory usage among the major competitors: http://lifehacker.com/browser-speed-tests/
