Keep Your Mac Cool by Controlling Your Laptop Fan

Last week I had one of those freak out moments when my laptop started acting like it had been possessed, as I had zero control over it. When it booted in safe mode, I knew it was time to get some backup assistance, and let's be honest, an involuntary safe boot on a Mac is almost like the blue screen of death on a PC.

Thankfully another resident geek guru came to my rescue and we both agreed that the 100-degree weather could be impairing my MacBook. And without further ado, he quickly installed one of his "fan favorites" (hee hee), smcFanControl. This free download allows you to control the built-in fan on every Intel Mac to make it run cooler. Macs are already insanely hot, so being able to rev up your fan from the default setting in hot weather definitely helps your Mac cool down. I've had it on full for the past week and it seems to be helping. Oh, and it also indicates the temperature of your laptop, so you can monitor whether you need the fan turned up.

Do you have a cool download like this one to share with geeksugar readers? To learn how to post your favorite sites to the Download of the Day group,

my boyfriend and i have been using this application for awhile now - but let me just note something. be careful using "non-apple" things like this. it was one of the things when my boyfriend's macbook pro started operating at the speed of my original ibook (my lower grade, year older macbook pro could boot and open programs in half the time he could) and two of the geniuses tried to blame the smcfan control for taking up RAM and slowing down the computer. they finally agreed that this was not the problem after two complete wipes of the computer, including one that erased information because the apple store insisted they could properly back up the computer (after us telling them that we had tried again and again) and they didn't back it up right. anyhow... this is a good application. just delete it before you take it in for repairs and download it again when you get it back. even if a genius suggested it... it can still cause "problems".
