i7 = 100 degrees C, unibody too thin?

[chill.]

You still don't get it. Here's the spoon-fed version.

The pertinent information from that data and graph is:

1) The CPU temp briefly reaches a max of 101 C (less than intel's recommended highest operating temp of 105 C for the i7 620M)

and

2) During this test, which is designed to max out the CPU, the enclosure bottom sensors never read more than 36 C (96.8 F). This is a relatively low temperature. Right now my 13" unibody macbook, with just Google chrome open, is reading 86 F for one of the bottom enclosure readings and I would describe it as tepid. Remember, the temp sensors are reading the inside temperature of the bottom enclosure.

Got it?

no. i don't get it. what part of the article is incorrect?

my concern is you keep quoting the macdailynews article everywhere like it's a nugget of gold when it's an unprofessional, spiteful review that is wrong on ALL counts. then you continually bash this pcauthority article when it is pretty accurate

Because what they are outlining isn't an actual problem. Can you tell me what the problem is? The CPU doesn't get too hot for intel's liking and the casing doesn't get too hot to use (which is PC Authority's implication and other sites have run away with it.) 93 F for the bottom enclosure is nothing to get worried about. Like I said, just surfing the web with Chrome open my unibody macbook has its bottom enclosure at 86F.

So what IS the problem? Please tell me.

Most of the macdailynews article is just saying "so, what's wrong here?" They got some details wrong about the CPU names though.

the problem is that the unibody is hitting temperatures which are 20 C higher than other cases. ANY heat at all shortens the longevity of hardware. obviously this should be a concern when mbp are producing significantly more heat than competitors, but it is expected since the case is so thin

and this high CPU temp in conjunction with the conductive aluminum shell makes the enclosure VERY hot. i have personally experienced times with my late 2008 unibody macbook while playing games, when the bottom case was too hot to hold my hand against it for more than 5 seconds at a time.

there is not necessarily a "problem" but pcauthority outlined possible concerns and recorded statistics, it's not like they said that the laptop would blow up. what they reported in the article is relevant and very valid

I read one guy said that this completely unacceptable because this is a pro machine and it gets too hot when I'm using FCS for encoding for a few hours. I understand the whole pro thing, but seriously? FCS encoding for a few hours! On a laptop! If your doing that much encoding get a workhorse. I personally think that's insane to be doing that much encoding on a laptop. If it's for projects very far and few between I understand, but if it's a monthly thing, get a Mac Pro. We tried laptops at my work when we first got into editing, and lets just say, 4 Mac Pro's now baby!

Yes, your 2008 MBP gets hot. True story, except not relevant to this article.

You are needlessly worried about the CPU temp. It's well within Intel's design specifications, which of course include a factor of safety (design factor does not equal factor of safety, engineering 101.) You don't really think that the chip will blow up if it hits 105C do you? Also, who cares what it's made out of? Irrelevant. The fact is the bottom enclosure, on the inside, during this benchmark didn't get hotter than 93F. The actual casing that touches your body would be warm at this point. Nowhere near hot. It's not like because it's made of aluminum it would magically get hotter than 93F on the outside.

So by your own admission: "there's not necessarily a problem"

Thank you.

All I'm saying is that article's implications are misleading because there is no problem here. In fact, it proves 2010 MBPs are pretty efficient at heat dissipation without burning the consumer (like the earlier Rev A MBPs did.)

what kind of distorted reality are you living in

my mb is in an alumnium unibody, and the cpu hits temps of 90+ C, and the case gets very hot. if you think it's not relevant in a comparison to an i7 in an alumnium unibody, and a cpu that hits temps of 90+ C, then i don't know what to say.

more heat reduces the lifespan of hardware. did you learn that in engineering 101 too?

where did i say the chip would blow up if it hit 105 C?

how is the case being made out of aluminum irrelevant? aluminum conducts heat much better than alternate materials like plastic or carbon fiber, and one of the concerns outlined was the computer being hot in your lap

my macbook has read 40 C as the bottom enclosure temp and has been BURNING. this makes me really doubt the placement and/or reading of the bottom enclosure sensor

you keep saying "implications", but i don't see any implications here, just reported facts and background information which is ALL TRUE

how are 2010 mbps efficient at heat dissipation when competitors are running 20 C lower?

The objective, fact-based, and logical one.

my mb is in an alumnium unibody, and the cpu hits temps of 90+ C, and the case gets very hot. if you think it's not relevant in a comparison to an i7 in an alumnium unibody, and a cpu that hits temps of 90+ C, then i don't know what to say.

You were trying to argue that because your aluminum 2008 MBP gets hot on your lap that the i7 must too. Which is just wrong.

more heat reduces the lifespan of hardware. did you learn that in engineering 101 too?

Does it matter if it reduces the CPU life from 50 to 49 years by momentarily spiking to 100 C a few times during its life?

where did i say the chip would blow up if it hit 105 C?

You didn't. I was assuming your argument was "105 C is too hot" since there was no hint of anything resembling an actual argument in your vague and confused posts.

how is the case being made out of aluminum irrelevant? aluminum conducts heat much better than alternate materials like plastic or carbon fiber, and one of the concerns outlined was the computer being hot in your lap

It's irrelevant because of the bottom casing temperature. Who cares if it's made out of aluminum, steel, plastic, or wool? A temperature is a temperature. 93F wool is just as hot as 93F aluminum. It will take more heat energy to get wool to 93F than aluminum because it has a lower thermal conductivity, but don't confuse that for actual temperature. Or maybe you think that a pound of rocks weighs more than a pound of feathers?

my macbook has read 40 C as the bottom enclosure temp and has been BURNING. this makes me really doubt the placement and/or reading of the bottom enclosure sensor

Fair point. I have no idea if the sensors in the 2010 MBPs are in the same place as the older MBPs. Do you? I would assume they haven't moved.

you keep saying "implications", but i don't see any implications here, just reported facts and background information which is ALL TRUE

It's the tone of the article and their omission of relevant information that is the problem. It leads people (like you) to think there is some fundamental design flaw with the new 2010 MBPs that is going to make their skin burn off while using it on their lap.

how are 2010 mbps efficient at heat dissipation when competitors are running 20 C lower?

Not relative to competitors with the i7 620M, relative to pervious gen MacBook Pros (such as yours, but especially the Rev A machines.)
