Hi i would like if anyone could help me as i have spent so long looking for and cannot find or get info on

I have a amd athlon x2 240 not overclocked and for some reason my cpu temp is when running games ect 23c MAX
i am pretty sure that before it was a little higher i have since found that it can handle upto 74 via AMD website i also have noticed a slight decrease in speed while running games. i think this started while my os was win7 64 bit ultimate and just crashed i since done a fresh install and gone back to win xp 64bit. it does run but as i say 23c while running high apps and games is this normal i would be very grateful if anyone could help me with this as i dont really want to pay to send it off but if no help then thats my only option thanks in advanced

More about : cpu temp low

There's no such thing as too cool ;)  But if you're sure these temps aren't right then you may have a faulty sensor. The only thing to worry about really is if your actual temp raises, you won't know about it. If it's not causing any problems though I wouldn't send it off.

Thanks alot thats got a load of my mind also what can i do about possibly having a faulty sensor also my cpu temp via bios says about 34c but when using at least 4 cpu heat programs they say 23c are these programs what you call sensor's or aree they something copmpletely different

You have various sensors on your motherboard that monitor temperatures of your components. If one of these becomes faulty then there isn't an awful lot you can do about it really apart from obviously a new motherboard. If its a question of what your BIOS says against a third-party program I would trust your BIOS.

What program are you using to monitor your temps? HWMonitor is a good free utility. Google it for the download. I have an Athlon II X4 at stock speeds and with the stock cooler and it runs very cool. It currently idles around 21-22C. If you have good airflow through your case then your temps are definitely possible. Like I said, I wouldn't worry too much about it, unless it starts causing problems. Good luck!

Thanks again mate much appreciated HWMonitor is one that i use aswell as a few others i cant remember the names as i got them yesterday and i am on a different pc thanks again as it has been buggin me cheers :)

Is that the "Core" temp or "CPU" temp. On my Athlon II 250, the core temp is low by around 10C. The CPU temp looks about right however. What does you CPU temp (in HWMonitor) say at idle/load (note it may be mislabeled, go with the one that changes).

I wish i had those temps :)  You should be happy :p 


lol i should be but it is only that i had a fatal crash and i am sure the cpu temp has changed and also slight reduced performance in gaming but then again i did have a mod with the game and now have removed it seems to run ok :S :p 

When temps are Low run your temp program while running prime95 and monitor the temps. Do they increase and do they seem resonable when the cpu is loaded. If the temps do not increase under load then the most likely cause is the software. 23 C under load seems low (no experience with your CPU), Would expect approx at least 8 to 10 C higher than your room temp.

Idle temps may, or may not be valid. Core temps will ALWAYS be higher than room (ambient) temp. The "on-die" sensors are not always accurate at low temps as they are designed to measure higher temps in order to protect the CPU from overheat (The sensor is accurate, but nonlinear and the measuring program does not compensate for the nonlineararity)

EXT64's idle temp of 10C is a good example of an invalid reading for an aircooled HSF, unless is house is like a fridge ( 50 F). Most likely the temp is below the software threashold and is displaying the low "Rail"

Thanks alot for your post i have taken on board what you have said and have a better understanding within this area of cpu thanks for taking the time to reply many thanks again :sol:

I just built a Athlon II x3 for my neighbor, on a rosewill zx5 heatsink his max is around 25c, the Athlon II architecture is amazingly low temped.


Thanks for the info glad to hear its not a problem within my system cheers :sol: 

I agree with you, personally i think there is something wrong with his motherboard, but he refuses to rma it for me. At this point I really don't care, the guy just wants a office cpu and I'm not woried about his cpu going up to max temp any time soon.

sorry when you say i refuse to rma 1st of i dont no what that means and second of all i am sorry if you have a had bad day dont take it out on me and i would only guess that you couldnt care less about my cpu maxing *** man some people
