I have been working on my current CDK14 scope with very good results. Here is a review of the scope:

The CDKs do come with fans on the rear backplate that blow air into the OTA. The larger scopes and newer versions have 4 x side fans as well to blow air across the primary - mine is brand new too but the CDK14 doesn't have side fans. I'm considering adding 4x fans to the side and wondering if there will be any extra benefit? The new DR350 which is a short FL CDK14 does have these fans as well. Beside more scrubbing of the boundary layer, another advantage could be the primary will be closer to ambient and may need less heat to prevent dew. These scopes to have heaters. Any ideals are welcomed. The new short version of the CDK14 attached (note 3x rear fans + 4x side fans).
