MacBook operating temps?

Okay, so I noticed checking various places on the net that MBP's run pretty hot under load. Usually around 80-90c doing video encoding or gaming etc... I noticed most people posting about Windows laptops seem to freak when temps hit 60-70c.

My question is, what is the discrepancy between the two? I haven't seen a mass freak out about macs overheating, neither PC's either really? Are people just paranoid?

Sorry I am sure this has been covered before, but it made me curious. I know tech decently well, but innards of laptops I have no clue.

 

LOL

It's called Mac Temp Neurosis, a form of obsessive compulsion (MTNOC).

Yes, I have noticed the preoccupation as well, and it makes no sense.
I have never worried about temps, nor have I engaged in the pastime of obsessive manual fan control.

I game, I encode video, I flash as well. Never a temperature related blip, even at 90 deg C.
Maybe I'm just not hardcore.

 

LOL priceless...there cant be any other proper term to describe this condition

 

Yeah, it gets hot. Yeah, the fans get noisy. But no stability issues here.

 

New macbook operates around 40C doing basic web stuff (on integrated graphics) and quickly jumps to 66-90C on games - and then fans kick in and temps seem to stay 60-70.

Or, you can just get something like SMC fan control and have it running 2-3k rpm prior to kicking in the game and have nice temps.

 

Actually, the fan is always at 2k RPM - but at that rate it is inaudible. When the temps get higher (mine idles around 50C) it kicks in and can really get screamin'.

 

I'm sad that Lubbo's isn't working properly for the 2011's.

hell, even HWMonitor doesn't seem to be able to properly list the GPU temperature. (No GPU temp sensor problems in OS X, however)

 

LOL at the first sentence, brilliant!

I tried a game on steam and it (13' i7) stayed about 84c

Encoding h.264 it was about 92-95c, to be expected in the small space I am sure. Got a little of the neurosis you mentioned though seeing a lot of threads with people saying 70c on their lappie was too hot and spazz out. Doesn't seem to bog down ever so F it.

 

Sometimes its needed... found on my 17" that it runs the fans too low even when maxed out, and when the 6750 is on, and it stays over 90, sometimes the machine will completely hard lock and I have to power it off. If I manually spin the fans up faster, its never a problem. I found posts all over the place of people gaming and other things on these with the locking up, so I'm not the only one... but I prevent all lock ups just by manually making the fans go faster. I expect a firmware update sometime for the computer since it rarely gets to full speed on its own no matter what.

 

Also guys remember... its aluminum, heat transfers through that like poop through a goose. Your entire case is essentially a big heat sink!

 

Still, the price to pay for a sleek design and no other vents besides where the screen hinge connects is going to be higher temps.

I like to use an app called Fan Control that integrates into the system preferences. It's more of a 'set it and forget it' solution rather than smc and I'd love if there was something like it for Windows. Lubbo's technically works but only really functions to manually set the fan speed at a fixed rpm.

Reading other forums, some people clam to have lowest at 30c with integrate graphics however I cant reach that low even switching on integrate graphic. My idle temperature is 48-55c integrated card (No adjustment in fans rpm and run only word with A/C plug in).

Will it be the reason that every macbook pro thermal paste are different? some said it is over paste of thermal paste.

 

period of usage is one issue. For instance, when I first bought the mac the temps always stayed in the 30s or less. but presently, around 4-5 months later it has started to rise up a bit and hits the 40-60 range under light load and 70-80 under heavy load. So your temps are really good and you should not worry about it. as long as you are not hitting >90s you are fine. I know how annoying the temperature issue is and gotta say I was a victim of it too bothering me all the time. But trust what the previous posters have said. Just enjoy your machine and dont bother too much about the temps.

by the way, are you by chance placing your laptop on a flat surface? coz if you can raise your machine a bit the temp might drop even further. Also another reason others might be getting a different temp reading compared to yours is because, 1) they might be living in a much colder place so ambient temp might be low to sustain the temp within that range you specified. 2) they have a method of circulating the air around the machine like using a USB fan or something.

Hope this helps

 

You'd think temperatures at the CPU and GPU level would be cooler with the case being one big heat sink.
