Hotend Reading Off

So i finally have my v-core 3 setup, however the hotend thermistor is reading 158 C at room temp. It is a rapido hotend, yet it reads wrong. I even bought a new hotend thinking the thermistor was bad but no. Same result.
The bed reads just fine, but not this. I even defined the thermistor as a custom type but that didnt fix it. Any suggestions?
