It may be the case that the fan on the CPU (together with the integrated GPU) may be sufficient in pulling away the excess heat, but at no doubt the cost of excessive noise (generated by 6,000 RPMs). Stressing the integrated chip will see the CPU spike in temperatures, which means that fan will be doing more work to handle the additional load. So using the discrete card may kick off additional heat, but it's also got a dedicated fan to push that heat away from the machine. In the case of MBP, models that possess discrete video cards have dual fans (one for the CPU and one for the GPU). I can see a reduction in power, but a reduction in heat, again, I'm not sold. GPUs put off heat, wether they're integrated or discrete. Use your faster GPU on AC Power, and lower on Battery power (use These guys have conducted some very loose tests that support your assertion, and I'm inclined to agree that Safari, being so tightly integrated into OS X should net improvements over its competitors across the board, but a few CPU cycles here and there aren't going to amount to a drop (drastic or modest) in temperatures (these saw extremely small differences in performance). Also flash youtube videos run with less resourcesĪgain, I'd like to see some data being this claim. This of courses comes at a sacrifice to noise (increasing it) and I'd like to see data on how much cooler the chips operate with such a small increase to RPM.ĭitch all browsers to Safari, I tried them all Firefox up to version 5Īnd 7 (Aurora), Chrome and Opera. Regular cleanings are essential!ĭownload and install Fan Control and run your fans 2800-3000 RPM Computers generally accumulate far more dust than people expect.
Dust sticks to the blades (and most of the internals) creating a "sticky" residue and not only prevents the fan's blades from spinning at their optimum, but seriously restricts air flow.
This is by far the most effective way to ensure your system continues to operate nominally over the years.
it's simple, open theīottom closure and blow the hell out of these fansĪbsolutely. Proper scientific methodology calls for the manipulation of one variable against a control (unless you want to run the more complex ANOVA).Ĭlean your MacBook Pro fans from within. Moreover, if you enacted all those changes at once, you'll never know which one made a real difference, and which one did absolutely nothing. Please don't take this a slight against you, but rather as a criticism of your general claims (and lack of scientific data therein). With that said, some practices you list are of critical importance others, I'm not sold on one bit. I tend to remain sceptical of anyone making claims without valid and reliable data. Keep your monitor running 90% brightness or less.Replace your internal hard drive with an SSD.Use your faster GPU on AC Power, and lower on Battery power (use gfxCardStatus for source-based GPU switching).Also flash youtube videos run with less resources on Safari for some reason. nothing beats the CPU usage (less of it) than Safari. Ditch all browsers to Safari, i tried them all Firefox up to version 5 and 7 (Aurora), Chrome and Opera.Position your MacBook on a hard surface.Download and install Fan Control and run your fans 2800-3000 RPM.it's simple, open the bottom closure and blow the hell out of these fans. Clean your MacBook Pro fans from within.I like it cold, here are a few tips I did to keep my MacBook Pro Unibody under 46 degrees C ~ 115 degrees F. I'm a developer/system admin/unix guy so I have many IDEs/Editors/Terminals running and I'm also temperature freak.
