CPUTIN = CPU Temperature Index
AUXTIN = Auxiliary Temperature Index
SYSTIN = System Temperature Index

CPUTIN is different from CoreTemp. CoreTemp is the sensor on the processor while CPUTIN is motherboard CPU temp sensor.
AUXTIN is the power supply temp sensor if there is one. While SYSTIN relates to Motherboard.
=====
TMPIN 0 = MOBO = SYS
TMPIN 1 = CPU
TMPIN 2 = MCH = Northbridge
TMPIN 3 = Sensor near GPU/VRMs

That max temp is the temp that your mobo can handle but its running pretty hot so your insides of the case must be warm

-EDITED-
DONT WORRY ABOUT THE TEMPS IT MAY BE FALSE READING CAUSE MOBO SENSORS ARE NOT VERY ACCURATE

That area being hot is pretty much alright cause its in gaming scenario nothing to worry about
