New T570 running hot

Yesterday while playing a not strenuous game the laptop was quite hot, on my mac i had installed a fan control software (smcFanControl) where the OS would only be overridden when i chose to manually tu up or down the fan, i tried that with this laptop and the fan control software most highly recommended seemed to fiddly so i uninstalled it.  Now the laptop is running hot with the fan on for tasks like Word where it never ran hot before. Any ideas on how to fix this? Laptop is less than two months old
