Inter-exposure cool-down period for DSLR?

Hi all

Just wondering for how long most people leave their standard DSLR (i.e. 350/450D) cool down between sequenced takes? If I am running a long sequence of, say 20x360-sec exposures, a fair amount of heat and therefore noise is generated by the sensor within that 360-sec exposure. If I don't let the camera cool between shots I imagine that heat from the prior shot would still be dissipating, and if I started the next exposure too soon after it'd result in a chip that is never given the chance to reach some sort of temperature stabilisation. Amp glow would also be exacerbated I'd assume

I'm considering leaving at least a 1-minute gap between frames. What do others do? Is a minute long enough at average summer night time ambient air temps?
