What are the regulations regarding hot and cold generator air temperatures?

First of all, you need to explain what type of generator it is and how powerful it is? As far as I know, there are no specific regulations on the temperature of wind or water used to cool generators. Of course, wind or higher temperature water cannot be used, otherwise they will not be able to cool the generator. Small oil, gas and wind generators are naturally air-cooled, and larger ones have their own fan. If this is insufficient, a fan can be added. The hydroelectric generator has its own water cooling device and a fan can also be added. The temperature of all generators generally cannot exceed 80 degrees.
