I don't think there is a way, but just make sure you keep the time capsule in a well ventilated area. Also the lower it is the cooler it gets, so don't put it on top of shelves (heat rises). If you live in a hot setting that may be the problem. Did it just start when summer started or before? If it was always like this, it MAY be a product defect, and I would look into that as well if I were you.
PS: Hard drives die a lot faster when its more then 50 degrees Celsius. If you can iron your cloths with it, the HDD inside is in danger...
