I7 3820 temperature questions

Hey Guys.
I just built my first computer (using an Intel i7 3820) and I have a few questions.

First of all, what is the best software for monitoring CPU temperatures? I'm currently using Fan Xpert+ (It came with the ASUS motherboard I Got). I gave SpeedFan a go but I was getting conflicting readings. Is there anything better/ more accurate out there? Also if there is, can i alter the fan speed if I feel like it?

Secondly, how hot should my CPU be when Idle. I'm currently getting between about 25 degrees (give or take a few degrees depending on ambient my room temperature). And what is the max temperature my CPU can reach before it gets dangerous?

I'm currently using stock settings on everything however I intend to overclock sooner or later.

Thanks for any help i can get :D

  1. Any third party can be wrong and none is better than others I use core temp and in it I can set offset which I calibrated to what BIOS was reading on startup. Max temp for your CPU is 66.8°C http://ark.intel.com/products/63698/Intel-Core-i7-3820-Processor-10M-Cache-up-to-3_80-GHz
  2. 66.8 is the average.

    The CPU will last up to 100 degrees before it shuts off and still then it wont be damaged.

    SB and IB both start to throttle down around 95 C (individual core temps)
    Myself I do not like to go above 70C when runing an intense application. Fot Prime95 which will genetally run hotter my max would be 80C. prime85 will often hit close to 80->85 C with the stock (junk) intel HSF.
