Hi All,

I was wondering if any of you have suggestions about keeping a MacBook cool. Like many MacBook owners, I suffered through the 'Random Shutdown Syndrome' (RSS), and after get my heatsink replaced at a local AASP, I started to notice that my MacBook was warmer. I read from various sites that that's because the new way they apply thermal paste and whatnot, so I sort understood and was able to tolerate it. However, lately it's been getting on my nerves again. Just moments ago when I picked up my MacBook to move over to my bed, I felt the table and thought that if I left the MacBook there any longer I'd burn a hole in it, makes me worry about my lap... So does anyone have a suggestion for keeping things cool?

You could try a utility like this one, to control your fan speeds:

If it almost burns to the touch, bring it in to an AASP, and have them take a look.

i'm actually already running that, but keeping the fan at 2500 minimum sometimes still doens't seem enough.

I picked up one of these for my macbook:

I rarely feel the need to turn on the fans. Actually, I never turn on the fans unless I'm playing Call o Duty 2. :) It also helps to keep it at a very ergonomic viewing level.

try 3000.. if its still getting too hot, bring it in.. because i run my MBP with fancontrol at 3000 and it stays cool..

I used to use a notebook cooler/fan but then I got lazy from having to plug it in every time i got home, but I suppose I could do that.

I use this (http://us.st11.yimg.com/us.st.yimg.com/I/yhst-38601269197435_1920_9177119) at home.

and use this (http://us.st11.yimg.com/us.st.yimg.com/I/yhst-38601269197435_1920_17677123) on the go. This is a passive cooling gel-filled pad.

this may sound kind of make shift for most but my powerbook is right by a window so i took a big pc cooling fan and i wired it to a usb male conector so that if i notice the temp. getting cooler i open the window and wedge the fan in there and plug it in, it actually works REALLY well. it sort of does exactly what an air conditioner does. if you have dead computers around you i would try that. i duno, it worked for me.

I've been using Cool Book (http://www.coolbook.se/CoolBook.html) with great success.

For normal surfing and typing I can lock my MacBook 2.0Ghz @ 1Ghz and .95 volts. If I need performance for photographic or video work I lock it at [email protected] volts.

Coolbook lets you set voltage and freq (within Intel's preset limits). If you choose to use it you should be careful when determining you minimum voltage and follow the user manual.

I found a huge difference in temperature under all conditions. My peak load temperature dropped 10 degrees C by reducing my voltage and my steady state temperature at low freq and voltage helped drastically with laptop use. I think it's silly that you can't use a laptop computer as a laptop. Computers are now "portables" instead of "laptops".

This program is only for someone who understands the ramifications of what they are doing. The worst of which is potential data loss if you freeze your computer. The voltage and frequency limits keep you from damaging your hardware.

My father uses a passive laptop cooler with heatpipes with his MBP. It works quite well at moving heat from the laptop to a large external heat sink on the back of the cooler without requiring any power or USB connections. He got it at Canada Computes but they no longer carry it.
