My motherboard gives me different temperature readings for my cpu than HWmonitor?

Question

I am using a 95Watt AMD Phenom ii X4 not overclocked kept at 3.2GHz. I am using the ASUS royal knight CPU cooler, and when i view the CPU temperature readings in my BIOS it says about 28°C and when i open HWmonitor aswell and core temp they both say about 12°C. however i do know that when i operating system boots at open catalyst control center it is set to make the CPU run at 800MHz when idle and 3.2GHz when high activity. So what is right, my motherboard or the software, or both assuming my CPU amazingly cools drastically down when booting somehow?

Answer 1

it is not unusual that the BIOS and other software monitors differ in the recorded temperatures. I would suspect that the 28 degrees is more accurate than the 12, that is very very low and usually only attainable with some sort of refrigerated cooling, and below 10 degrees is actually not good anyway as the risk of condensation forming is far greater below that figure.

Try uninstalling the HWmonitor software, reboot and reload again, you may find it will be more accurate if you do.

The best way is to download Ccleaner here http://bitly.com/UrALrK



Or you can go on Windows operating system locate the command prompt and go there to do the following:

Create a Recovery file of system and date it today.



Then begin by;

delete the 'Temp' folders..they have hidden subfolders so you need to set the attributes in order to bypass this. For each subfolder delete all cookies and rubbish left behnd after install-uninstalled programs. Do a 'dir' command to check your progress. Make sure the 'Temp' file is empty.



goto c:\windows\prefetch and delete everything in there..no exceptions



goto c:\windows folder and delete all the '$' files that have been installed by updates. They can all be succesfully deleted and just take up disk space.



Locate the Internet Temporary Files..Check to see how high the saving level is..some have it set at 30 days..but that stores faaaar tooo much data..though it slows down the system overal. Keep this to a minimum..suggest 2 or 5 at most.



Delete all 'cookies' all those you don't need.



Locate the windows directory and go through the folders you know and those you don't need. Check this once a week at least. Some programs will install under XP as NT and older systems where there is no check of systems weight.



Check to see that system files have not changed since last booting. Things like .ini files or .bat are important items.





Check for 'Hidden Directories' all over the disk...do this at the command prompt:



dir *.* /ah wil show these hidden directories



Check the 'dir' command for all parameters

Answer 3

They could both be right, assuming that the computer is running "at idle" when you're getting these readings. I put that in quotations because the idle state is kind of relative. The BIOS version of "idle" is about 50% load at normal clock and the operating system's version of "idle" is about 5% at 800mhz, as you've configured in the CCC. Since the CPU heats up the more work its doing, and it's doing much more work when you're checking the temps in the BIOS, it stands to reason that the temperature you'd see there would be higher.



Of course, 12C is exceptionally low, and while this is attainable with the correct combination of cooling and underclocking, pretty unrealistic on air cooled PCs. The programs you're using to read the temps may not be correctly calibrated.

Answer 4

Your BIOS probably has the right temperature. Sometimes HWMonitor does not give accurate temperatures for some reason. You would need a very cool room to get to 12°C. There is no way that it can get to lower temperature than the surrounding air.

Answer 5

Well

The first thing to do to speed up pc and get rid of malwares and viruses is cleaning the registry with a program like CCLeaner http://j.mp/UrADse

until eventually now each and each little ingredient, confirm to make effectual there is sufficient air flowing around the PSU, if the case is indoors a closed cabinet or shelf, bypass it so it get sufficient cool air bypass. confirm the interior, incl around the PSU for airborne dirt and dirt, and factors you a physically powerful sparkling, even confirm rear, the front and section vents are sparkling and get sufficient air bypass. between the fundamental killers of computers is loss of air bypass and airborne dirt and dirt. circumstances with section fixed and greater useful rear fixed followers are desirable as they permit greater useful air to bypass over the internals.
