I'm not positive but I think TMPIN0 is your system temperature (Northbridge temperature) and the TMPIN1 is the CPU (Socket temperature). I could be wrong, it maybe the Mosfet Temperatures. But whatever temperature it is reporting, it's way to hot, or it's just reporting incorrectly. What motherboard are you using? Did it come with some sort of Monitoring utility? You should be able to run it and HWMonitor at the same time and figure out what's what. We need to figure out what TMPIN0 is in order to fix it/cool it down.
Your actual cpu temps are listed as Core#0, Core#1, Core#2 and Core#3. These are also a little high, your using the stock cooler are you also overclocking it a little?
A "Good" Thermal paste can lower your temps by a couple of degrees at best, usually.

I buy a lot of stuff from this shop. There in Florida so you have to pay tax but they have fast shipping. I live in Jacksonville and I usually have my package in 2 days. You can save a buck or so at NewEgg but it will be 3-5 days before it arrives.

A good heatsink is always a smart move if you can afford one. Your looking at $50-$100+ for a "Good to Best".
