CPU temp disagreement?!

Intel XTU says my CPU is 190°F, but when I measure the temp with an infared thermometer, it reads it as 116°F...

Which do I trust? Intel XTU (RealTemp and CoreTemp say the same) or the infared thermometer?
 
Solution
the 190F is the temp inside the cpu possibly at the location of each core. Some CPUs have a sensor for each core while cheaper CPUs have only one sensor to take a measurement of the entire CPU package. The reason your infrared thermometer is reading such a wildly different measurement is because you are measuring the temperature on the outside of the CPU as opposed to the inside.

Stay with what coretemp says. Both devices are correct but what you should pay mind to is the internal temperature measured by the CPU itself.

Ok, thanks for the help!

One more question, is 88°C too hot for a Xeon X5650? Every now and then it his 95° for half a second then drops to about 79-88C° during a stress test. It is currently overclocked to 3.2GHz with 1.3375v

70-80C is an average temperature for a CPU under load. 90C is running hot. Anything above and you will risk degrading the CPU faster. 60C is ideal for load temperatures. You will probably only reach 60C with a liquid cooler.

In Just Cause 3 (Ultra settings @ 1080p) it only runs up to like 68C so I'm good, right?
