Image by Walter Galan/ The system can get very hot on the bottom, which can get uncomfortable for many people. Not to say this doesn't happen with the other models, or laptops in general, but this happens naturally with the newer MacBooks. There is a way you can control your fan's speed and power to prevent this from happening, and it's completely safe (if used properly), and easy to do. So, let's get to it. Macs Fan Control by CrystalIDEA Software is one of many fan controlling programs for Mac (like and ), but this is one of the more stable and user-friendly applications out of the bunch. Step 1: Installing Macs Fan Control First, head to to download Macs Fan Control onto your computer. Make sure to choose the 'Macs Fan Control for Mac OS X' download, not the 'Boot Camp' one.

Fan Control is a hassle-free fan speed manager for MacBooks. Do you think your MacBook or MacBook Pro is running too hot? Then give Fan Control a try. Some MacBooks (Pro) are just to hot for daylong use.

Once download, unzip the file and move the app to your Applications folder. The options available in the menu bar shortcut include the following. • Show Macs Fan Control will take you to the program, if you have it hidden in the menu bar.

• Website and Check for updates is pretty self-explanatory. • Left/Right side - Auto will allow you to change the fan speed, which learn about later. • Preferences shows advanced controls that we won't be needing, though you may want to change your temperature stats from Celsius to Fahrenheit here, depending on which you're used to. • Exit will exit out of the program entirely.

Step 3: Understanding the Mac Fans Control UI This program's main window has all the information you need to understand what you're going to do, and what your limits are. • Min RPM is as slow and powerless as your fan should go. • Current RPM is the speed your fan is currently running at. • Max RPM is the highest possible speed your fan can go. You don't ever want to go to that speed or near it. • Control is the way that fan is being controlled.

By default, it's going to be running on Auto, which means the fans have complete control of their speed at all times. This is what we can change to allow our fans to work harder and cool down our system. Temperature Sensors (Right Side) The right side of the window shows the temperature of all the parts of your system.

• Sensor shows the sensors in your system which are on various parts. Psychological horror games online free. • Value shows the temperature of this sensor. The default scale is Celsius, though, as I mentioned before, you can change this in the app's preferences. Just glancing at the fans and sensors information will give you a good idea of whether or not something is heating up a little too much. Step 4: Tweaking Your Fans' Speed Now that we understand the information given to us, let's see how we can tweak it. Go to the left side of the window and double-click on the fan you want to affect. In this example, I'll change the left fan, but you should change both fans to the same speed when doing this procedure.

Your Mac will be begin cooling if you selected the right temperature. You will be able to hear the fan at higher rates, but it won't be doing any harm to your system. Remember to change your other fan to the same speed, so they're running evenly. Warning: Do Not Leave Your Fans on 24/7 Do not leave your Mac running with this fan speed longer than the time you're using it. It will not cause damage for time-to-time use, but you do not want this to be a 24/7 operation. It would be best to use software like this to cool your system down while it's hot, and then reset to normal values. Step 5: Return to Original Settings Once you've solved your heating problem, it's time to return to the original settings to prevent the fans from staying at the speed that we set.

Go back to the same fan(s) you selected before, and double-click it again. This time, select the first option, Automatic (controlled by system), to go back to normal.

I don't think you quite understand Macs Fan Control. Each fan is controlled separately.

A MBP only has two fans. If you want them to both work the same, then you should select the same sensor - The CPU sensor that typically runs hotter.

You will see that in the configuration window. Then set the 'kick in' temperature to around 40º C. Do this for each fan.

Configuring SMC Fan Control is just as easy but is done based only on setting the base fan speed. SMC Fan Control is only capable of setting the idle fan speed.

That may be a better choice for a laptop than Macs Fan Control, but you should try them out before deciding which you prefer. As for iStat Menues you do not have to switch profiles. Create your desired profile as the 'Default' profile or the 'Medium' profile, select that profile as the default, then Save your settings. There is no need to switch them to anything. I use iStat to set the fans on my iMac and I never need to change them.
