Personally, I think you're probably fine.

SMC FAN CONTROL TEMPERATURE FREE
(I don't know of any problems caused by it, but to be fair it would be wrong to say it's risk free ) Research before you try something like that, and remember that there's always a risk when you use programs like that. If you use it, and decide to go back and let the system manage itself, you'll have to uninstall it and reset the SMC. I am sure there are others but I don't know them. There are programs out there that can make it so that you control the fans. But some feel that lower temps are better, and wish to manually control their fan speeds. The studies and things I have read and seen, show that they stay (or at least my model) stays well within safe ranges. You'll hear disputes that they get too hot for the HDD for example. Some people are uncomfortable with the temps that Apple has engineered these machines to run at. When you're doing harder tasks, rendering videos, gaming, things like that, the temps will go up some, but the fans will keep them in safe ranges. It should get to a certain temp if you're doing light tasks, such as browsing, emails, word processing, photos, etc.
SMC FAN CONTROL TEMPERATURE FULL
They should not "kick up" to full blast, ever. Rest assured, the fans run constantly If you write down the fan speeds that iStat shows, and check them as you're using the computer, they will increase and decrease with the temp.
