I need help starting a Terminal command at start-up to help silence CPU fan

Question

I have a 24" iMac (Early 2009) and the CPU fan runs at full RPMs - NOTE: it is a refurbished model. I think that the person who did the refurbishing either messed up the CPU Temp Sensor or something, because the CPU temps are fine and the fan kicks on right after start-up chime.
Anyways, I have found a terminal command (see below) that, when used in conjunction with smcFanControl, will force my CPU fan to run at 1200 RPM. I need a way to either auto-launch this Terminal Command at start-up, or an easier way to launch it because having to type it out in Terminal every boot and reset is getting old.
Terminal Command:
/Applications/smcFanControl.app/Contents/Resources/smc -k F2Mx -w 3cf0
Any help would be greatly appreciated!

You shell script should look something like this:
#!/bin/bash
your command line
Construct this in your favorite text editor and save as plain text, not .rtf.  Call the file anything you want, but here I'll call it slowfan.
In terminal type,
chmod +x /path/to/slowfan
where /path/to/slowfan is the path to the slowfan file.  You could drag the file into the terminal after typing the chmod +x followed by a space.  This step is only to mark the text file (script) as executable.
Now you can run Platypus and set up a simple app with admin privleges.  Then test the app.  If it works you can then add it to your login items.
If you decide to use applescript (do shell script descibed earlier) then you could just use the full pathname to whereever you saved the script and save that as a applescript application.  Again test it and then add to your login items.  I would bother adding an alias to .bash_profile.  That just adds to the complextity.
As you can see, with Platypus you only have the single app it creates to deal with.  The script is enclosed in the generated app bundle for easy updating if necessary later on.  With the applescript method you will need to keep track of two spearate files; the applescript and the shell script.  Actually three, the app too.
