I have this explosion, where all the action takes place at frame 0 and cooling is set to 1.0 so I thought it would dissipate quicker than this?

Oh, cooling of 1 is not the maximum - just boost it further 
We have to cap the cooling to 1 so it would work like the smoke dissipation, but currently you can set it to as big a value as you like.
