u can skip this ......just few hours back i bought a amd fx 6300 and a entry level mobo i.e GA-78LMT-USB3 (rev. 5.0) loved playing crysis 3 @ v.high with low AA on my gtx 560ti (before i was only doing med settings on my core 2 quad q8300:(  )

i was trying to monitor the temps of the cpu, (btw i've a CM hyper 212) on idle, temp's fluctuating a lot like 19, 29,35,20 etc every second but on load is 35,36 while playing crysis 3

plz gelp me out , how to get accurate temp's, because of improper temps, my cpu PWM fan is fluctuating like hell.

FYI: in bios pc health stats on boot up it shows 45 degrees stable with (1350rpm out of 1800rpm for my CM hyper 212)

plz help me out, do i have to chage any settings in bios???

AMD thermal sensors are a bit inaccurate at low temps.

What program are you using to monitor temps? Try coretemp

Someone else might be able to provide better information on this but from what I understand that's a known problem. The idle temp will be all over the place but once you get it under load then that reading is supposed to be accurate.

The FX series CPUs have a feature that allows them to throttle up and down as necessary (depending on what is needed to run the applications you have open at that time) in order to reduce heat and draw less power. This will cause the temps at idle to fluctuate as background processes do more or less. It is perfectly normal, and helps you reduce your power bill by not drawing more power than it needs. If you want to disable it, look in your BIOS for the Cool'n'Quiet setting.

Edit: If you want to overclock at some point in the future, you will need to disable this first as well, so if that is your plan, remember this setting even if you choose to leave it enabled for now.

okay, thanx for replies but why my beefy CM 212, running at very high rpms on idle :(  :( 
what about re-installing OS itself (WIN 8),, is it worth giving a try???

i've used H/W monitor, and all cpu meter gadget (with pcmeter 0.3)

If your thermal paste isn't applied correctly or isn't high enough quality, it could be causing poor heat transfer which would make your fan run faster to compensate. What thermal paste did you use, and how did you apply it?

am using the paste which i got with my cooler master hyper 212 cooler, (which was a small injection), but after applying and fixing, i rotated cooler by 90 degree as it's airflow orientation was wrong(my bad), will it affect contact btw them
(btw em really worried one of my friend while removing cooler, damaged his cpu pins )

Turning the cooler after applying the thermal paste could definitely have caused a problem with it. I would suggest removing it, cleaning the paste off with a very soft cloth and some rubbing alcohol, and reapplying the paste after it dries. Don't worry about damaging your CPU; it happens occasionally, but is rare in my experience. As you're removing the cooler, turn it a little before lifting to loosen the thermal paste and it should prevent the CPU from being damaged.

The video linked below shows how to apply the thermal paste correctly using the pea method, just make sure that you put the cooler on facing the correct direction so you don't have to rotate it again.
