Core i5 & i7 Overheating Issues True?

MBHockey said:
That's not really a valid comparison. Run skype on both computers and you'll see the temps shoot up.

Here are some temps from my core i7 MBP...I've been using it on my lap on battery power for about an hour (temps in Fahrenheit):

It was the same thing, Skype, TweetDeck and Firefox running on the i5. :rolleyes:
 
I have an MBP i5 15" HR with a 7200 rpm drive I installed and it runs cool even under lots of use.

I guess maybe the i7 is a lot worse or something?

I've been ripping stuff in Handbrake with 100% CPU and everything firing and my 17 " i7 hasn't gone much above 55C.

I would guess that on such a fast machine Handbrake is limited by the DVD not the CPU. Certainly even on my measly C2D that's the case - with Handbrake the CPU doesn't get pegged at 100%. I suspect if you run some of the many artificial CPU-taxers floating about it will get hotter than that.

I had a 10 movie deep queue on Handbrake (all pre-ripped on to my SSD with RipIt) and had my core i7 15" process them all in a row. Handbrake was pegged around 380%-390% the entire time and my CPU temp stabilized around 180F after the fans came on. Ran that for a few hours and it cooled down very quickly once it was done.

No issues whatsoever.

The DVD wasn't engaged. I've been converting DVD VTS files to m4v, etc straight from my SSD.

With the other things I was doing, the CPU was consistently above 98% according to the activity monitor. The fans came on, but the temp didn't reach anything remotely alarming.

probably not for everyone, but had some issues when connecting an external display, which switched the new MacBook Pro to switch to discrete GPU. For normal use though, not such a big of an issue.

Check here if interested.

switching to an external display only or an extended desktop mode or connecting a projector or to a HDTV will always switch to discrete graphics in the new MBP's

Ding. Ding. We have a winner. :D

Not sure how Pax thought I wasn't really pushing my CPU with Handbrake.

Because your CPU is very, very cool for something going at 4 x 100%. 55 C seems anomalously low. I assumed you were ripping from the DVD drive. I really can't see a CPU staying that cool while dissipating 35 Watts. Some posters are seeing idle temperatures like that, when the CPU is dissipating just a few Watts.

You should post your findings here

As you'll see, users on there (and a few on this thread) who have redlined their i7 CPU has run it up to around or above 90 C and some have touched 100 C maximum.
 
I dont know if anyone else i having similar problems but when i run starcraft ONE on my mid i5 macbook pro with 4gb ram it sometimes crashes completely with the screen turning black. I dont know if this is due to the program itself but the machine gets extremely hot. This is alarming because, i would like to think that the starcraft campaign wouldnt demand that much processing power......any thoughts?
 
Might be a hardware compatibility issue? I have a few old games that won't work on newer computers for some reason.
 
I5

When running Starcraft 2 on my mbp i5 I experience heating issues within about 5 minutes. My comp is only hitting around 189 degrees but it will actually cause my graphics to flip out. Spiky discolored images appear all over the screen. I had the same issue on my older iMac when running wow a year or so ago. I've been turning my fans to full power and it still sticks around 180ish. Bought a cooling pad to keep from damaging anything internal. Anyone have any suggestions? I feel like I shouldn't need a cooling pad to safely game with my computer
 
With my i7 15" running SC2 it got pretty hot by the exhaust near the screen. I could still touch it but I didn't have a tempurture monitor installed so I don't know what it was running at.

When using the 330m the machine runs a bit warmer, but I use gfxCardStatus and switch to Intel only when doing normal tasks to save battery life and then it is very cool.
 
It tends to take a little bit before the fans kick in, under full load my 15" i7 can get over 80C but then once the fans kick in its will stay in the 70s.

Slightly off topic, but the 330m stays very cool, I have mine overclocked quite a bit in windows and have done all day gaming sessions and the heat didn't go over 70C on the gpu and the processor was in the 70s as well.
 
Overheats and crashes for me

I have a MBP i7 Mid-2010.

I played serious games on here (I'm a game developer) with no problem for 2 months, and now it overheats and causes a total system crash where you can hear sound looping in the background, the screen goes black, and there is zero responsiveness from anything except holding down the power button.

This began last night, and has continued all through last night and today. Crashes occur about an hour into playing anything modern (Arkham Asylum, StarCraft II, etc.)

I am going in for a replacement unit. Good thing I have time machine...
 
Temperatures

I installed a temperature monitor. Looks like core 4 is overheating far more than the others at 101c, while the others run at about 96c during medium graphics StarCraft II.

Notice I did not have problems until last night, so it's likely that I've had a hardware failure when playing Arkham Asylum then.

I did notice some weirdness when playing games, but I have no way to correlate that wonkiness with the temperature though it did seem to progressively get worst.

Hope this helps.
 
To be honest, I've had a lot of crashes in the last 2 months with high-end games (I've got about 30 games+ installed at any given time), and while I cannot correlate them with temperature because I was not monitoring it then, I just figured at the time that it was par for the course with windows.

I play SC2 in OSX, and the crashes occur in games in both OSX and Windows, so that is another bit of evidence that it is hardware related.
