Dropbox Growl Overheated Processor

Over the weekend, I went and installed Dropbox to move some pictures between a MBP and an iPad. Seemed like a good idea at the time. Later the next day on the MBP while running Windows 7 in Parallels, a message pops up and says my processor has overheated. Of course, I am floored and deeply concerned (while thinking hmm that's a nice new feature in Snow Leopard). Much to my surprise, it is not a new feature but a sneaky little add-on called Growl that came along with Dropbox on my system. At first, I think it's a nice addition, but now I am ******. I have installed FanControl to keep my processor cool. I have a widget called miniSTAT that say it was running at 57C and after the fan control stays at 54C. But all my research on temps seem to say both are normal running temps.

So why did Growl say my processor overheated?
FanControl says both fans are running. And MiniSTAT confirms it. Do I have another possible source of trouble?
I removed my battery because the taskbar says it's in need of service, even though the battery itself shows full charge. It the original battery on my MBP. So maybe that is pith source of heat? Stinks I gotta buy a new one.

Any help or ideas are greatly appreciated...
