    I went in to the Apple Store yesterday to buy a MacBook pro 15". I currently have a 2009 13" MacBook Pro. I decided to go top of the line with the i7 even though the Apple Sale Person said I didn't need the speed. I wanted to not look back later and say I should have gotten the best. What I noticed last night was I had it on my lap on battery power doing my normal surfing. On flash sites it got a bit uncomfortable on my lap. About 70 degrees C. I have never noticed it before on my 13". Should I take it back for an i5 and would that make any difference or is all of this just normal for this type of computer? Thanks everyone.

    It's normal. Probably even on the "cool" side for using Flash.

    Thanks. I just noticed the difference from my 13" when using flash but I guess running i7 processors is going to produce more heat than my 13"? Would it have made any difference if I had gotten the i5?

    Doubtful. Even if it ran a few degrees cooler it'd probably still be uncomfortable.

    Yeah it was a bit hot on the legs. Just wondering why so much difference over my 13" c2d. Just the difference in the processors assuming that the i7 produces more heat? My thinking was a new processor design should produce less heat????

    I really don't feel the i5 gets hot, not compared to the C2D i had.
    With in safari with 6 tabs open, playing youtube for 10 mins, word'08, mail and adium open it reached 51°C. After the clips was done it went to down 41°C within 2 mins.
    Fans didn't spin up either.

    This is the i5 tho.
    (edit down to 38°C now)

    Well it's about 20°C in this room and the i5 MBP is now 37°C.
    If you have any youtube clips you want me to run now and post temps, I'd be happy to do it.
    And yes I'm on battery too, which I always am when i'm using it on my lap :D

    My 15" i7 is currently sat at 36°C, browsing with mobile broadband dongle running, mail open, and 3 firefox windows, on my desk battery powered.

    The only time I have experienced temperatures that high is when my Lexmark wireless printer wouldn't print from my MBP. It kept trying to push the job through and was using 99% CPU for a couple of hours.

    I couldn't find the cause until I downloaded istat and saw the high CPU usage caused by the lexmark script.

    had the same problem with my lexmark wireless printer. It was using 100% of the CPU as a background task. I got about 2.5 hours of battery life because of it. Little to my knowlege, this was the reason I was getting bad battery life. I actually went as far as contacting apple about it. Their replacing the machine (even though it doesnt need to be replaced now that ive solved the problem) but ive already filed the claim and everything is ready to go so i might as well do it. Also, if this was not the root of my battery problem and I contact apple about it, their answer is going to be well we offered to replace the computer but you declined.... So as to avoid a future hassle. I figured I might as well go ahead with the replacement that has already been set up. Looks like I will be Macless for a few days :rolleyes:

    That is a great temp. Mine will not get quite that cool just surfing. Not sure if I want to take it back or not. Maybe this is all within the range that is acceptable except for my legs being singed:)

    Yup, exactly the same. I was like... What!! I was fully charged just a short time ago. I don't think any permanent damage has been caused though.

    If you could look at your enclosure temperatures eg in iStat and post them on there. The OP on that thread seems to have a "hot" base a bit like you & wants to know whether others do.

    talking about i5/i7 heating. does anyone's 15" i7 500gb 7200rpm mbp make noise? It's not LOUD. but usually laptops are real silent right? im sitting here in my silent room and i can hear the fan or w/e it is making the air noise pretty clearly. i have it charging right now, could that be the reason? i dunno if its normal.

    The 7200 rpm drive in my i7 15" MBP was both loud and vibrated the heck out of the palm rests. I ended up removing it, went with an SSD, and now the MBP is dead-silent. I mean no noise or vibration at all. IMHO, the chassis design + 7200 rpm drives don't mix well.

    Why take a 200.00 restocking fee charge?

    Yeah, I know what you mean. I was hoping they might waive it with the complaint the machine is running hot. It is only a day old. However, I'm not there yet. Still getting information and playing with it to see exactly how hot the bottom enclosure gets. Taking it back or exchanging would be the last thing I'd like to do.

    If you're exchanging due to a heat problem there will be no restocking fee.

    The 09 15" MBP 2.8 ghz, 512vram runs noticeably cooler than the new i7 with 512vram and ssd.

    13" MBP also runs noticeably cooler in our experience.

    Later this year I think there will be new i5/i7's that use less power and run cooler.

    Yeh the i7 quads generate a lot of heat both in the HP Envy and the Macs. Personally I like the top I5's better overal and usually in test their just as fast if not a little faster the the i7s. I don't need the extra capabilities of quadcores as I don't do any video or heavy designing etc.

    Are the i5's running similar temps to the i7's?

    My 15" i7 easily gets up to 70C and when I play WoW on High (Ultra works too but I lag in Dalaran) it maxes out at about 75C. I don't understand how some people's MacBook Pro's are hitting 100C. Get some airflow in your house.
