Does the Qaud core i7 27" imac get any hotter than the i5

[applefan14]

I don't know if you have used the new Quad core i7 and i5 imac together but i will be getting one of them but do you think the Quad core i7 would get any hotter when gaming and multitasking and video editing compared to the i5 which has 4 cores and only turbo boost. also i have heard that if you game for a couple of hours on the i7 it tends to get really hotter then the i5 which most people say you should just get the i5 as it cooler and just as fast.

Basically says is there any temp difference between the i7 and i5 when vid editing gaming and multi tasking

Of course it gets little hotter when under load because it has higher clock speed and Hyper-Threading enabled. Is it an issue? Definitely not. It's not something you should worry about, the system takes care of cooling.

I would agree with OSx, but with Windows 7 (Boot camp drivers installed) I found my i7 got so hot it was almost impossible to touch. This, when gaming on stock GPU/CPU. I have resolved this with Macfan on "Slightly higher" settings for normal stock gaming/computting.

It's never a problem on OSx.

Possible reasons?

- The mobility radeon drivers mess up the fan control
- MacOsx has software that is "Preventative" in spinning up the fans?
- Windows7 has no "Preventative" software, and waits for the hardware "Firmware" to spin up the fans, too late in my opinion

Anyway I have no idea why, but in my case the i7 gets hot under Win7, but not under OSx. Using Macfan resolves this issue.

Yeah b/c when i get the imac i5 or i7 i want to have a cool computer ill probably use osx for video editing and all other stuff and just windows for games. Im thinking it will be constantly hot when it is on. what cpu do you think i should get as the little speed difference between the two.

Is it worth getting the i7 as well as the heat it produces or should i get the i5

I regret the i7 as the only CPU intensive stuff I do is gaming, and this hardly scratches the CPU. (Arma2, GTAiV, Crysis, Dirt2, Fallout3, BFBC2, HL2)

For me, the i5 would have been the smarter choice, just as my buddy (Apple store regional director) told me.

I suggest you go for the i5 and use the extra on something else.

Have you used both systems is there any huge difference between them. ive used the i5 and its really fast open every thing instantly. then when they have the i7 im thinking it would be even faster. I have looked at the geek benches and there isnt a huge jump.

So you think i5 would be the way to go. if i do get i5 ill prob use the 260 or what ever for some speakers and a kanex xd to connect my ps3 to it.

Also I want to get the i7 but the way i see it there is no point in spending the extra when they are almost the same apart from the hyper treading 4 more cores which can be good if you exporting HD video playing a game and have 10 apps open as ill prob do the above about spending the 260 on something else.

If the i7's added tdp would be enough to not warrant its use over the i5, then Apple wouldn't be able to sell the i7 in the first place. The i7 does get hotter than the i5 by a little bit, but the amount is miniscule (only 2-5c under osx-- can't speak for windows)

If you're looking at time it takes for programs to load as a demonstration of speed from the cpus, then you probably don't need the lynnfield cpus in the first place. The real advantage of the lynnfield cpus comes from headroom when multitasking and video editing rather than raw speed. (A clarkdale will appear just as fast as lynnfield when doing normal tasks)

The case of the iMac even gets extremely hot to the touch under osx as well, but the external temperature of the case is not something to worry about.
