hot hot hot hot
I've a MacBook Pro(15" Core 2 Duo Model A1211). I'm very fond of it except it's heating issues.
Last year I gave it to it's official service in my country to clean it's inside up from dust. They did so and it's temperature decreased some. At winter I'd no problem since the weather was cool but with summer on the door my Mac started to get hot again.
Well, it's not as hot as before service time but it started getting hot again. Especially when emptying the trash or encoding a video. I know that it should get hot at those kind of times but would changing it's thermal paste do any vast change since I read a lot of articles on the web that Apple doesn't know how to apply thermal paste and how cool their Mac got when they changed their's thermal paste.
Thanks for your answers guys. Really shaped my way.
I've been using smcFanControl for quite some time. I set my fans to start running on 3500 rpm.
Some time ago I reinstalled my OS X. Well, it wasn't the reinstallation of Snow Leopard which I use at the moment but it was Tiger back then. I installed Snow Leopard not as a fresh install but as default(archive & install) from the installation disc.
I'm considering CoolBook but I've some questions about it. Would I have to change the clock speed of my CPU? If not only changing my fans revolutions per minute with CoolBook make any difference than smcFanControl.
Also I've 4 GB's of 667 MHz DDR2 SDRAM on my Mac. That's why I don't think that the RAM amount is a problem. And my HDD is 320 GB with 7200 rpm. But if you still think that that amount of RAM is not enough or my disk needs re-fragmentation I'd love to read your thoughts.
All in all, I'm definitely considering opening my Mac and re-applying the thermal paste. So could you please advice me the best one.
Это хороший вопрос?
CoolBook has nothing to do with fan rpm control. You can use CoolBook to alter the minimum voltage of you CPU for any given clock speed. For example, my MacBook's CPU voltage setting when running on 2.1Ghz was 1.1375V. Using CoolBook, I managed to lower the setting to just 0.9750V, which is around 20% less voltage in the core, which also means 20% less heat and consumption as well. Since I installed and configured CoolBook, I have NEVER heard the fan running to its max setting.
Configuring CoolBook is somehow troublesome (you'll have to test your CPU's limits in lower voltages by trial and error meaning a bunch of restarts, but once you've read and understood the readmes, you'll be up and running with a cooler MacBook in less than an hour.
As a final note, CoolBook UNDERVOLTS the CPU, it does NOT overclock it. The CPU can NOT be damaged by undervolting it, you'll just end up with a couple of kernel panics in the process. In other words, read the manual well.
