When are you taking these shots?
If your taking them whilst inside, make sure the cap/whatever is over the end of the lens properly and use some alfoil to cover the noise point.
That being said, this could be heat related.
Set a delay between shots of say 10sec and start again. Does it still build up over time?
Also, make sure you keep an eye on your histogram sliders in Maxim, in case the sliders are moving for some reason (do you have it set to auto? try manual if so).
Open up say the 110 BIAS file and make sure the sliders take the full histogram into account. Cut off part of it and you will get images that look like this on your screen, but the actual data is fine.
