Depends on the origin of the neutrino. The really old ones leftover from the beginning of the universe are so low-energy that they’re like, a millionth of an electron volt. Very not-hot.
A supernova-originated neutrino can have over 30 mega-electron-volts. For a single particle, that’s pretty hot. You still wouldn’t feel it if it hit you though.
