Put a fan on em and the q-tip method you used works fine.
Pod heat depends on plant stress and the climate. The more stress and the hotter the climate, the hotter the pods will be.
You dont want to stress your plants to much! Just water them when they begin to wilt and you should have some hot pods. One more thing, by the time your plants flower you should have them outdoors, so you dont have to hand pollinate. You can just let nature do it for you. Unless you intend on just growing indoors.
Good luck.
