Solved Aida64 shows same temp reading for CPU & mobo

November 20, 2011 at 08:47:00
Specs: Win7 Ultimate SP1, Intel QuadCore i5-760@2.80GHz_3.50 RAM
Installed Aida64 to monitor my computer's temperatures and was surprised to learn that my CPU & motherboard's temp readings are practically the same in idle state as well as when loaded. Tried Aida64's System Stability Test for 4 minutes and the CPU temp kicked in at 61 degress celsius max along with the motherboard temperature at 61 too. Unloaded the CPU and the temp drops to 37 along with the board too. Now my concern is why does my CPU & motherboard have the same temperature readings? How'd this happen? Help, please.

The temp readings in the bios have been tweaked in the bios's code such that they're quite accurate for the particular mboard model.

Third party hardware monitoring programs make assumptions about the sensor readings that may not be correct for the particular mboard model. You can usually tweak the settings in the third party program so they match or are close to what the readings in the bios are.

Sometimes sensors for something are not connected to the intended inputs on the hardware monitoring chips - the mboard manufacturer compensates for that, but the third party program doesn't.

The third party program may show a reading for an input no sensor is connected to - it never changes in that case, and may even be an impossible reading.

Asus's own Probe hardware monitoring program is usually quite accurate for Asus mboards. If you have the CD that came with the mboard, it's probably on that for you to install.
Or it can usually be downloaded from the software downloads for your mboard model on the Asus web site.

May be it's a software fault, try using different soft like SIW or Hwmonitor. I see no problems with the temp.

Tried HWMonitor and the results are the same, both the CPU & motherboard (ASUS P7P55D E-LX) have the same temp readings. Will this irregular behavior cause problems in the days ahead and if so, how do I fix this?

Check the board & CPU temp in BIOS. I don't think there is a problem.

Checked the BIOS CPU & board temps & I think there's no problem there.
CPU = 46 to 46.5 degrees C
MB = 36 degrees C

There must be a logical explanation to this uncanny behaviour. Will this be a problem? And would you say AIDA64 is displaying the correct temp readings, how accurate is this app? Meanwhile, I'll try to do some research and see where it leads me. Later.

I still have the support cd that came with the board but I manage to download the latest version of Probe in their web site. Installed the app., compared the results of my BIOS with Probe and as accurate as can be, share the same readings. I'm glad we got this sorted out. I was starting to get worried thinking this might cause me problems. I think I'll install this software on my other desktop which also is posting some weird temperature readings. Thank you and thank you guys for being patient with me and the help extended.

I have been using these monitoring apps for a long time now and each time i see some weird readings i run into BIOS. Lets hope the next version of AIDA64 fixes this bug. Good explanation from Tubes.

Thanks for the thank yous.

Other mboard manufacturers often have their own hardware monitoring program you can install, although in some cases it may not be on the CD that came with or in the software downloads for the retail model but it's avalable on the brand name's web site somewhere, e.g. some Intel models.
If you have a desktop brand name system, if you can determine which mboard manufacturer actually made the mboard, you can use that manufacturer's hardware monitoring program.
