Am I the only one who notices it's the PC users who jump on top of this stuff. Kind of sad...

Of course not. I was just mentioning that it happened.

(HP Envy)1 3/16.6" compared to (MBP)19/20 of an inch.

I was using an example of a C2Duo CPU with no fan. With a working fan it maxes out at 85C. Intel i3's perform similar tasks with less heat output and you have a much better cooling fan on your Envy that actually works. The grill on the side of your laptop allows for much more airflow.

Did you check to see if the CPU was throttling down at all? The only reason my laptop with a broken fan can reach 102C is because I prevent throttling down with CoolBook. By default it throttles down around 80C.

Also, the aluminum case transmits heat much more than the plastic shell of PCs. Another reason why a PC laptop isn't as hot to touch. You still wouldn't want to put 80C on your lap without wearing jeans though.

That's weird. My Lenovo T500 with the same GPU idles @ 43*C and under load never capped 80*C.

Its only 1.08" think or approximately 1/8" thicker than MBP... ie... less than half the size difference your ruler shows...

Yea obviously I have better cooling, that was my point!!!! Maybe your broken fan shouldn't be broken... mine works... I don't understand how this is a positive for MBP in the slightest... plus we already know its hitting 93C not 85C... I am not even cracking 80C at 3rd to fastest fan speed!!!!

No, obviously it isn't throttling if max fan isn't coming on at 80C... but I went back and checked anyway, no its NOT throttling. I did this test with my computer on my lap at 78C... it is completely comfortable. In boxers...

My point is that prime95 torture test hits not even 80C on my laptop... 93C opening zip archives is ridiculous and should never happen. As to why youre trying to justify it I have no clue. Ill roll over dead when I see a Core2Duo MBP running prime95 under 80C... lol.

My i7 32nm allendale sucks for thermal throttling and it's hotter than the macbook pro is claimed to run.

Yes I will try to redo teh thermal compount again.

I've found the same problems on "normal" windows laptops. They just get far to hot
My laptop can sit on a duvet all day and still be exceptionally cool to the touch. Only gets remotely toasty while running a heavy app.

You just need to buy the right laptop, and if heat really matters to you look in to an ultra-low voltage chip. Pricey, but well worth it.

Not possible. Only Apple laptops have heating issues.

HP website says 1.18" height. Another reason it's cooler. The plastic casing makes it cooler to the touch as well(and looks cheap).

You don't know how to check the current clock speed then. Guessing by fan speeds isn't the way to do it.

Keep in mind that when anandtech tested it. they found it perfect, no throttling. Turboboost perfect.
