I think alot of people use smcFanControl this way. Some may argue that any such use of fan control can shorten the life of the fans. While this may be true, the question is by how much. You may still end up upgrading to a new MBP before the fans ever fail.

If you want to avoid the issue all together you can get a regular lap desk or a cooling lap desk and leave the fans alone.

It's not that I am worried about any discomfort to myself because of heat. I am only worried about keeping the vital components in my mac in great working condition for as long as possible. If the fans go out, which i don't believe will because of my little use of SMC Fan Control, it is definitely a cheaper repair than if the cpu or other vital components were to go out due to long term heat.

The internal components are designed to take the heat of the CPU and other hot components. They can actually take much more heat then that of the CPU, whose maximum is about 105C. Parts in the early 2000's and before can't really handle the heat because they just weren't able to because of their manufacturing processes.
 
My opinion

Hey i live in Australia and things get pretty hot down here. look if my opinion is still valid (i stop reading when people started "having a go") I personally use a program called 'smc Fan Control' by using this i can adjust the thresholds in order to get my fan up to about 4500rpm now i do not run this program all the time but i like to run it just after/whilst playing game or watching movies as temperatures can top 59*C and this is just not good now in my view its easier to replace a fan if you are out of warranty anyway (many videos out there on how to do this) than it would be to run the risk of overheating my mac (lets face it programs fail every now and then) therefore the download link is: http://fan-control.en.softonic.com/mac (for any one who is looking) its a handy little program to have as it also gives you a temp reading at the top of your screen and you can always revert back to apple presets without uninstalling the program

Cheers Daz23
 
i do not run this program all the time but i like to run it just after/whilst playing game or watching movies as temperatures can top 59*C
59C is nothing to be concerned about. Read the earlier posts about maximum and safe operating temps and you'll see 59C is quite normal and significantly below any maximum. Your Mac doesn't need any 3rd party app to properly manage fans and temps.
 
Hi, can someone please tell me how I can force my MacBook Air's fan to run at full speed all the time, to keep it as cool as possible. Currently I'm using smcFan Control but it still adjusts the fan speed to the CPU Load. With the Fan Control prefpane it's possible to set a minimum fan speed of no more than 3500 RPM.
Thanks for any help.

You need to know that by doing that you will only work out your MBA and is pointless. I own a Macbook Air too and it is working fine. The only time where my fans are blowing at max. speed is when I run a lot of processes on it and utilise my RAM a lot.
