my bet is you go for the arduino solution
easy as fuck to set up a simple temperature & humidity sensor, cheap as fuck also if you the buy Chinese off brand stuff
hundred of examples and guides on the interweb about to make an arduino run shit with a DTH11 sensor.

Also, If I may, I think you don't need such a contraption of cooling system to make your animal comfortable, I would put the fan attached in only one specific part of the cage (a cooling spot) and run the fan at low speed (for instance, powering it directly from the 5VDC bus on the arduino itself or even having the fan running directly from a 5VDC power source, no arduinos or sensor needed) and let animal decide which part of the cage is better depending on current conditions.
