So far I haven't done any serious number crunching with it but playing flash videos and running IM clients my i7 has stayed cool as a cucumber. It got slightly warm when I was charging it with the laptop still on my lap but nothing to complain about.

I'll be using Handbrake soon and let you know how hot it gets.

There's already another thread on this.

Engadget is just linking to some bootleg tech site where they had an MBP get to 100 C without the fans kicking in, as pointed out by someone in the other thread.

There's obviously something wrong with that specific unit for the fans not to go past 2000 rpm when the CPU is that hot. It's a lemon.

Reputable tech sites show that they run cooler than last gen MBPs, which weren't that hot to begin with.

Well I did a search for that thread. Got a link?

maybe the mods can merge them.

I figured as much. They are cranking it hard with Cinebench
Doesn't explain why the fans are sitting at idle speed.

The maximum operating temperature of the i7 620M is 105 C (http://www.cpu-world.com/CPUs/Core_i7/Intel-Core i7 Mobile I7-620M CP80617003981AH.html)

The fans should kick on well before you get within 3 degrees of the CPUs maximum operating temperature. If you think that Apple designed a computer to NOT do that, you are mistaken.

This unit is obviously defective. How a tech site didn't come to this conclusion yet I did after 3 minutes of Googling is astounding.

Maybe they are just looking for hits then. :confused:

That or they're incompetent. I smell a combination of both :)

I'm surprised at Engadget for linking to that site. But at least engadget acknowledges that PC Authority's experience is not normal.

I find myself reading Engadget much less these days to be honest. I'm either getting older and crustier, or their antics and headlines are getting too TMZ for my taste

Too much like a tabloid paper; dramatic stories/headlines for bigger readership?

They post such flamebait news stories and the comment section is a whole other mouthbreather universe altogether

sounds like a lot of owner's bias on here.. which is understandable.. after all.. you just purchased a 2000 computer you'd hate to read all this negatives about it..

:D

My new i7 2.66 15" machine is currently rendering something and it's doing a bunch of downloads in the background. So my CPU is heavily taxed. Fans are running pretty high right now and I'm sitting at 158 F according to iStat. This is still about 25-30 F cooler than my 2007 non-Unibody MBP as this is a normal Monday morning task for me so I know it well. I should also note, however, that these tasks used to take 4-5 hours to run every Monday and I'm 85% done 2 hours into the normal process.

Hot...yes. Better than what I had? Absolutely.

**Edit**
And the process just finished in 40% of the same time it took last week. I'm no benchmark, but for my real-world usage, this increase in speed is AMAZING. Wow. I only have the 7200-RPM hard drive in here but I can only imagine how much more of a boost I'd have gotten with a SSD. Just...Wow.

Maybe but someone pointed out (from memory) that the fans were only at 2000rpm? So they didn't kick in when expected, hence it was running hot. So defective laptop? Bum testing? Who knows. I'm not going to believe everything I read, though it is the internet, which as we all know is the The Fountain of Truth. :D

the temps of he heatsink were reaching +70 Degrees C simply running google chrome, and itunes. i love the 15inch mbp i have but i sometimes wish i had chosen the i5. maybe its a software related issue?

I for one welcome the arrival of the iMitt. Although I'm upset that I can't get it in charcoal black to match my Speck case.

Oh wait, it just melted. No problem now!

That's pretty cool that you're able to tax your system that much. It's cool to hear folks using these new processors to do real work and not just make the OS feel "snappier". I wish I fell into that category. Although I use a reasonable amount of CPU when I on occasion read in and reformat a 300+ million row CSV with a bunch of sed/awk scripts or compile software but it's nothing like people such as yourself rendering for a few hours straight. :)
