^ Good thought as I would like to know as well and if manually setting the fan control might help with the heat buildup issue.
I don't think its really necessary. I installed it on mine, and promptly removed it because my iMac stays at around 30-31C when browsing, iChat, and listening to music. If I'm watching a Blu-Ray rip (H264/MKV), temps hover around 34C. To be honest, I have not seen it go over 45C.

What heat buildup issue?
My 2.93GHz i7 gets pretty warm when encoding a video with HandBrake, but with all 8 virtual cores maxed out at near 100% for 15+ minutes or more, I expect it to get hot. The fans come on as they should, they cool the machine down, and when the processing is done the fans eventually slow. The iMac is designed to deal with the heat.
I run smcfancontrol on the i7 iMac and it operates normally as fan as I can see.
It's very simple to configure.
I use it on my iMac and it works great. I use mostly as a preemptive measure to raise the fan speeds when I am doing heavy editing or video work. Seems to make things run smoother.

Can you raise and lower the speed of the fans with this software or it it only a diagnostic system?
Thanks
Yes you can control the speed all the way from their lowest speeds to their highest. SMC make it pretty easy to control with a dialogue box in your menu bar. On my old MBP it was essential in ever getting anything done. I would leave it maxed out all the time since heat would slow it down so much. On my new iMac however I keep the fans just below half power when doing heavy work, I let OSX decide if it needs to go higher than that.
I would like to know if anyone has tried to use SMC Fan Control with the new iMac's ?
how about istat?
iStat from what I know doesn't give you as much control and flexibility as SMC fan control.
sure it does.
