Another solution I have in my arsenal is a Targus ChillMat, which is a laptop platform containing two large diameter, USB-powered fans that draw air through channels molded into the laptop support surface, exhausting it out the back of the unit. However, for the warm months, a more active approach may be required. If your laptop has a contoured bottom (a first generation iBook, for example) you can remove the center supports and it will work just fine using only the two outer supports. The Podium CoolPad measures 8-1/2 x 11 inches, weighs 1 pound. Most laptops – er, notebooks – dissipate some of their heat through the bottom and the more air that’s allowed to flow under the bottom, the better opportunity that heat will have to dissipate. It should be as efficient as any of the several laptop stand choices that aid cooling efficiency by raising the ‘Book off the support surface to allow air to circulate underneath. It’s still robust enough to support the 17″ PowerBook, and it comes in white to match the iBook, so it looks sharp. I like the Podium CoolPad because it’s small, light, and easy to stuff in a backpack or computer case. It cuts in at about 58.5° C and stays running until the processor temperature drops to 55° C. My new (to me) 17″ 1.33 GHz G4 PowerBook‘s fan runs a lot, perhaps half the time or more in summer weather, and that’s with the ‘Book sitting on a RoadTools Podium CoolPad, but at least it’s not as raucous as the Pismo and iBook fans. Given the way things are going with laptop heat generation, I guess I should be thankful that I live in a relatively chilly part of the world. The Pismo’s fan does a passable impression of a 767 taking off, and I really don’t want to have to listen it on a routine basis. The cooling fans are a lot noisier than even the most decrepit hard drives of my recollection, and once they cut in, they stay running for a long time before finally falling silent again. #XPAD LAPTOP COOLING FULL#The iBook’s Radeon 7500 GPU supports Quartz Extreme (which the Pismo doesn’t) but is not programmable for full support for Core Image and Core Graphics, so some of the load that would otherwise be handled by the video processor is likely getting shunted to the IBM 750FX CPU in it as well. The Rage Mobility 128 GPU with 8 MB of VRAM in the Pismo is really not up to dealing gracefully with Tiger. I’m glad my iBook’s hard drive is very quiet, because there seems to be some thing or things keeping it busy much of the time in Tiger.ĭaystar’s Gary Dailey says he has noticed that Tiger is putting more stress on the CPUs of the older systems, and he assumes this is due to the lack of a suitable GPU for offloading the Core Image and Core Graphics calls in these machines. My guess is that it probably has something to do with Tiger’s more intense video support demands, and perhaps stuff like Spotlight indexer running in the background. Under OS X 10.3 Panther, my little iBook’s fan had never come on, not even once, through the hottest stretches of two summers, so this was something new. However, after I installed OS X 10.4, the Pismo’s fan began spinning up as much as three or four times a day – as opposed to virtually never – and the weather really wasn’t that warm here through the spring of ’05. #XPAD LAPTOP COOLING UPGRADE#(The processor upgrade vendor, Daystar, retrofitted me with a replacement copper heat sink, replacing the Pismo’s original composite one, which helped keep the heat down to about the same as it had been with the original 500 MHz G3 processor.) Prior to 10.4, the cooling fans in my 700 MHz G3 iBook and 550 MHz G4 upgraded Pismo had remained pretty much silent, even during hot summer weather. After OS X 10.4 Tiger was released in early 2005, I noted a significant increase in reader mail either mentioning or complaining about more frequent fan cycling on PowerBooks and iBooks as well, and my own machines ran noticeably hotter (although still relatively tepid compared with the Macintels) after I installed Tiger. #XPAD LAPTOP COOLING PORTABLE#Indeed, Apple no longer advertises its portable computers as laptops, presumably fearing product liability lawsuits should someone singe their thighs.īut it’s not just the Macintel ‘Books. The new MacBook Pros and MacBooks run hot – almost hot enough to fry eggs.
