MacBook Pro temperatures

Message #1 - Posted 2008/01/04 - Pd

My 17" MBP 2.6GHz seems to get very hot.
According to Hardware Monitor, it regularly gets readings above 80∞C from the "CPU A Temperature Diode", with the Graphics Processor and Core 1 and 2 trailing by only a degree or so.

Is this normal for one of these egg-frying Intels?

Yes. Grab a copy of smcFanControl and bump up the fans for a few minutes when it gets a bit toasty.

There are 2 versions. I like the previous version myself.

I have a 2.16ghz and never seen temps for anything above 58C. 80C does seem very high? I uses iStat Pro to monitor and fans very rarely go about 2,000rpm - unless playing X-Plane, then then go up to 4,000 rpm, but temp stays around high 50's

Interesting. Makes an incredible difference immediately.

I can hear the fans above 2400 rpm, but not below that.

For some reason I find it weirdly exciting that this computer has 13 temperature sensors. Pity none of them actually measure ambient air temperature, although there is one called Ambient Air. It can't be room temperature though - I wouldn't be sitting here in loads of clothes if it really was 38 degrees in here.

You would if it was 38 degrees Farenheit, which has been the outside temperature here all day (Peter, sorry Pete, Cockcroft on the London news said it was going to be 10 degrees C in High Wycombe today, and that's only about 10 miles down the road, if that. Well, the outside thermometer here never got above 3 - and we're not in the Chilterns or anything).

I've given up trusting forecasts.

Define "egg-frying intels".

Do you mean: Is this normal for Intel Core Duo and Core 2 Duo processors in general?

If so, the answer is no. The "core" range of processors typically run far more efficiently and hence much cooler than Intel's previous "Pentium 4" range.

However, Apple seem to have them running hotter than just about any other manufacturer whose computers I've seen lately. It's within the thermal spec for the part though...

Do you mean: Is this normal for the macbook range of laptops?

If so, then they do typically run quite hot, though having said that 80 does seem a little high to me unless you are absolutely hammering the processor whenever you get readings in that range. Are the fans kicking in ok?

Define "egg-frying intels".

Actually it's a bit of a non sequitur, because it's a reference to the G4 powered PowerBooks, which really did get hot enough to fry eggs as demonstrated by Martin at Idea Digital.

I probably should have said something like "can these intel-powered laptops fry eggs like the old G4s?"

If so, then they do typically run quite hot, though having said that 80 does seem a little high to me unless you are absolutely hammering the processor whenever you get readings in that range. Are the fans kicking in ok?

83C was the CPU A Temperature Diode, although the CPU cores and the Graphics Temperature Diode also get up around 80 when I'm doing graphics intensive stuff such as playing a movie.

Does seem a little on the high side to me, possibly not enough to worry about as such though.

My fifteen-incher averages around 60∞C when under light load, 70∞C under medium-heavy load and I have seen it going up to 80∞C once or twice when really hammering the thing. It's currently showing 67 (thanks to MenuMeters, which may give slightly different readings) while running MacSOUP, Transmission, Pages, Safari and Omniweb.

Okay, so that's another data point that says these things can get quite hot. What's that about MenuMeters? v1.3 doesn't have any temperature displays, or have I missed something?

Sorry, I meant iStat menus (I used to use MenuMeters but dropped it in favour of iStat menus for the temperature and fan monitoring).

There's also an iStat widget which gives all the info in one window (rather than split into menus).
