MacBook reaching 80+ degrees

I've seen my macbook's cpu (november revision) hit 190 degrees Fahrenheit, and while the fans were going a full speed, everything was fine and nothing exciting (fortunately) happened. There are lots of articles online about macbooks running hot but the impression I get is that the machines are doing just fine. I've posted a link to a forum where someone asks a question about the macbook's temperature:

Don’t worry about the temperature of your MacBook. Mine gets to temperatures of around 90° to 145° F. but then the fans turn on full force and my MacBook cools off then goes back to being around 85° F.

80° F. is pretty normal temperature conditions for computers.

Yeah, from everyone I've talked to (myself included), MacBooks run very hot. I wouldn't worry about it unless you experience a problem.

Careful not to burn your legs! 🙂

Which 80+ degrees? 80C or 80F? Both are not the same.

my macbook runs at 80C and higher when going to certain websites full of flash applications like www.wakfu.com using osx. at "normal" websites it runs at 60C (using istat to measure the temp)

using windows w/ bootcamp however runs cooler at 60C even in flash websites

maybe there is something "wrong" with how osx handles flash based websites?

however, for me, something is "wrong" with macbooks temp, my uncles asus laptop is not that "hot" and can be used on the lap 🙂

I think it's self-evident that the poster meant 80 C; 80 F is slightly above room temperature.

Wondering about Flash causing high CPU use--since not all Flash content does this, is it caused by graphics-intensive code that, in a Macbook Pro, would be handled by the graphics card?

have no idea regarding the video card of the macbook, however, i did a test on browsing through a website with 2 macbooks, one which was mine and the other was a display at the store.

the stores macbook was quiet and runs cooler than mine. browsing through a specific website the temp only rose around 2 degrees

on my macbook it was quiet as well however it runs hot (around 62C for a long period of time.) browsing the same specific website made the fan run at full speed and the temp shot as high as 80C. looking at cpu usage it goes up to 90+% cpu usage

How does one measure the temperature of the MacBook CPU?
Mine feels hot too.

SOmeone suggested a widget, stat, but it doesn't show CPU temperature.

Thanks,

Here is the widget that I use. It works great!

To have it show the temperature of the CPU, you have to change the settings by clicking on the "i" button in the lower right hand corner.

I prefer SMC Fan control.

Firstly, activating the Dashboard can increase the temperature straight away, depending on how complex your other widgets are and what they do.

Second, smcFanControl sits in the menubar, providing a constant temperature reading. At the same time it gives you a reading on your current fan speed.

Third, you can set different fan speed settings. I override my "default" fan settings, setting the RPM higher than Apple's default, to keep the CPU temperature down slightly (though possibly at the cost of battery life). I can even tell the fans to go full blast even if it's not necessary.

Thanks, I dl'd istat, and it didn't show CPU temp or much else, then someone told me istat pro was the one I needed, and it's great.
All's well. Temp is about 140 F, and fan's rpm is about 1800. So, I should be fine.
Take care,

My dashboard has only the basics, what came with the MB. But I'm gonna try what you suggest.
I'll let you know...
Thanks!

Mine runs about 50-60 when viewing websites while listening to music. 80c is a bit hot. but nothing out of the ordinary..

Just dl'd it. It's great! Sitting up there atop the screen.
Thanks again!
