Just cancelled my 15" i5 order - too hot?

Scott6666 said:
I'm not pissing and moaning for the weighing it. I appreciate it very much. In fact it's made me comfortable enough that I had my :apple: business rep grab me a 15" matte that I will pick up today. There are enough positive comments on this that it's worth giving a try. Picking one up at the store rather than BTO gives me some comfort that I return it if I am pickier than the rest of the community. I just thought that one comment was a bit snarky, which I think is a problem in this community in general. I wish people would stay on topic rather than going after each other.

So thanks all, I'll post my impressions on noise and heat later today.

I you could use something like iStat Pro, and report the temps in Fahrenheit, and Celsius. I know fahrenheit better though.

Thanks
 
I have a MacBook 2008 Unibody here. Here are my temps:

CPU: 66 degrees Celsius/153 Fahrenheit
HD (500GB Hitachi 7200rpm): 34 degrees Celsius/92 Fahrenheit

Only running:
iCal
Firefox (16 tabs open)
Mail
Skype

Oh, and I just did SMC reset and zapped PRAM.

:rolleyes:

But those temps aren't when ideal or is it? Download CPU test, or handbreak. Or just run a VERY CPU intensive app for a while, and let me know the temps. Then turn the MB off, and wait several hours. Then power it back up, and let it sit with no programs open for 20 minutes. Let me know the temps when ideal. When doing CPU intensive things, My Latitude D620 (Core Duo T2300E same as 1st generation MacBook Pro) my temps are around 120F-150F. When using Core damage it goes to 160F-187F max.
This is after I re-applied Arctic Silver a short time ago. Now when the laptop is ideal it stays 90F-108F, and thats the CPU. Right now, I have my other Hard drive in with Windows 7 Pro, so its not a hackintosh at the moment. Right now as i'm typing it the temps are 127F
 
I did some testing to my laptop. I used a CPU stressor, and let the fans do their job. Then I purposely prevented the fan from spinning. (QUESTION: Even w/o the fan spinning, the temps raised, but then dropped. Was this cause by the CPu maybe slowing down to prevent damage? I'm not sure if it slowed down anyways.) Then I put the fans of TURBO 4553 RPM. I should be clear, that I let the temps hit the max w.o the fan, and when they started to drop, I took out the paper clip, and let the fan spin. It dropped the temps. So to be fare, you need to look at the peak temp, and it was 186F.

Top left image: computer being stressed with the fan acting normal (default dell settings)

Bottom left image: computer after being stressed w/o fan. Fan is shown in the picture spinning at full speed. temps have droped. The peak shows hot hot it reached w/o a spinning fan

Top right image: computer after being cooled down, and rebooted. Not 15 minutes sorry. I had the fan on turbo to cool it down as shown in the bottom left. once it was cooled, I restated, and tool an image about 2-3 minutes after boot.

Just a little experiment to see how my computer's thermal paste application, fan, and heatsink perform.

I have a 17" 2.66 C2D unibody, and I'll chime in on my temps

Browsing on Safari - no flash, Tweetie, Mail, iChat - 45-48c
Handbrake - blu ray 1080p MKV encode to Apple TV preset - 80-82c

Either way it looks as though my new laptop's going to run hotter than my old dell!

At the moment with my fans blazing I get it down to about 60c no matter what it's doing (not that it can do much with it's 1.6ghz core duo processor lol).

wait. your old dell had the 1.6GHz cpu or the macbook pro?
 
I am amazed these run as cool as they do. I have an I5 desktop that I built granted it is 4 core etc. But I have a cooler the size of a VW bug on it. Keeps temps below 40 degrees and around 50 degrees running handbrake full bore. These laptops obviously run higher temps. But I am amazed you can even run handbrake or something as intensive without them burning up.

I think some people expect to much from mobile computers. They are very powerful but for a gaming machine or a machine you want to do heavy encoding really need a desktop with a lot of ventilation, good fan system and a heavy duty cooler.


Looking forward to getting my macbook pro next week.

the i5, i7 in laptops have a lower TDP. They are LESS powerful, and generate much less heat, and use LESS energy. Its not that amazing.

Really do you have to be condescending. Really not necessary. I stated plainly my desktop i5 runs 4 cores. I build and tweak computers all the time and understand these laptops are less powerful. I promise you I am not an idiot.

Sorry it is amazing you can even actually encode on a laptop at all with decent results. Even at half or quarter speed is fantastic for a device that is 1 inch thick. The heat dissipation at these levels is really good considering the real estate.

But thanks for your expert opinion.

You are certainly welcome. think about it. Laptop have been around for years. My laptop from 2006 is still speedy even with Windows 7. it can do a lot. An old laptop from 2001 (HP) can still do everything we can do today. just older operating systems and software. Yes they weight more, but its nothing exciting and new.
 
CPU temp and all arent important here. Noone is saying the Macbooks overheat, they are saying the unibody design simply dissipates far too much to be comfortable. My experience with the unibodies has been the same - far too hot when doing actual work to use anywhere but a desk. Its an issue with the unibody design itself, until apple changes it it will continue.

The issue is when you have a chip generating so much heat, it can shorten the life if it. The heat may be fine for the CPu, and GPu, but not for all the little surrounding chips. they probably weren't designed for that high of a temp.

What kind of work do you do on battery power that makes your MacBook this hot?

Usually when I do 'real' work i'm plugged in and at the desk, but for light usage I use it on my lap with no problem.
 
While it is up to everybody to decide if you think the MBP run TOO hot, the thread starter complained he doesn't like it because it is hotter than the old C2D MBP according to Anandtech.

I like Anand's articles but sometimes even he forgets to mention a important fact explicitly. Anand is comparing the two cheapest 15" models. The old cheapest 15" had only 9400M and NO 9600M GT. He compares a 15" with C2D & 9400M with a 15" with Core i5 & 330M. Off course it runs hotter but compare it to a 9600M GT old 15" and things might be different.

All recent Apple laptops get hot there. It's normal, and it's a good sign it is very hot. Hot=more dissipation. If it was cold, where would the heat be going?

That makes no sense whatsoever. Hot = bad dissipation. If it was cold the CPU isn't being taxed.

The dell! Sorry I didn't make that clear!

I think the 1.66 GHz Intel Core Duo T2300E is still capable. It runs Windows 7 fine. It runs Snow leopard fine. Based on your reasoning, you could say the 1.6 GHz Intel Core i7 (quad core) can't do much either. GHz isn't accounting for everything in computers these days.
 
I have a 15" i7 antiglare in hand to test, brought home from the Apple store just now.

UNFORTUNATELY, the wife made dinner plans with the neighbors :( so testing will have to wait until later today or tomorrow.

She's a little peeved since we're supposed to be there at 6pm Eastern and I am typing an update to you all.

Simple: she goes alone :D
 
I had the 2006 core duo. It burned my legs, literally. This computer gets warm, but thats it. Try using a hard shell case, it helps as well. Played hulu for awhile and it warmed up, but with the hard case, its not hot at all. It sitting on my lap.

I don't know if I would upgrade if i had the model before this one, but if you need to upgrade, I think this is an excellent computer.
