ASI120MM sensor temperatures

[JamesF]

What sort of temperatures are people seeing from their ASI120MMs at the moment?

I used to get around 5C above ambient, but recently to try to keep the sensor clean I fitted an optical window to mine (newer models have them anyhow, I believe).  I'm imaging right now and the ambient temperature can't be more than 10C, but the camera is recording 27C!  That seems quite extreme to me.  I'm half-tempted to remove the optical window again.

Don't have one but  glass is a pretty good thermal insulator so I suspect the tenperature would rise by a fair amount..
