My issue is that sensor temp in FNQ is often up around 38 - 39 degrees. Adding a Peltier would likely result in condensation (our dew point can be up around 23 - 24 degrees) which as you correctly state would ultimately be disastrous for a camera not designed for cooling.
My thinking is that if a heatsink & fan could reduce temp by say 5 degrees, I might lose some heat related noise but, avoid condensation?
What are your thoughts on this approach?

Yes, moving air over a heat sink will have some effect. A quality heat sink will be better than a cheap one, but you don't have a lot of room to work with on those uncooked cameras. A DSLR, like a Canon 450D, is actually a good choice because you can get a copper finger behind the sensor, so you can stop it from heating up beyond ambient.
But it is not a trivial mod to that camera, see rcheshire's thread on cooling in the archive here.
Good luck, i will be interested in what you come up with.
