core temp vs cpu temp

What is the difference between core temp and cpu temp? I have put together a system for a friend with the AMD FX 8350 and it is cooled with a corsair H100i. Core temps are being reported 15-20C Lower than Cpu Temps. For example, at idle, Core temps are around 15C while CPU temps are 33C. On all cores 100% load, cpu temps are 63C while core temps are like 49C. The room temp is around 25C so is this even possible, or are the sensors just messed up? I used Core Temp, Hardware Monitor and CorsairLink2 to monitor temps. All give consistent results.

Second Question, which temperature is more accurate indicator in terms of determining overheating head room?

Thanks for the help.
 
Thats odd because it should be the same. 15C is a little low to be the gpu/cpu core.
You must have misread the temps somehow.
 
You did not misread the temps..... Mine sits idle around 15 C as well, give or take a few depending on the day.

I have an FX-8350 with H100i as well. I saw the same thing & thought it was weird. Core temp is the actual temperature of the cores inside the CPU. The CPU temp is the temperature of the socket on the motherboard. They're measuring different things.

The Core temp is the important one though. Keep that under 62 degrees. I read something somewhere that said the socket temp should stay under 65, but I cant remember where I read that and have no idea if that is true.
