CPU Temps - Propietary vs. 3rd Party monitoring software.

post #1 of 8
Thread Starter 
Hello, today I set up a custom aircooling for my box.
For cpu temps I have all type of monitoring software like: CoreTemp, HWMonitor Pro, ASUS Sensors (propietary software) and a random windows gadget.

So, before the air *modding* I had the same cpu temp on all these programs (around ~32-34C on idle).
But today I'm seeing a huge difference between all the 3rd party programs and the ASUS Sensors program (which is around of 10C difference).

Here's some pics:
Idle

As you can obviously see, there are some differences between the 3rd party for about 2-3C, and a huge 10C difference with the ASUS Sensors.

Load

Another huge difference for about 10C?!

Tell me what you think guys, what software should I rely on?

Edit: I have an ASUS P8P67 mobo (important fact as the ASUS Sensors should be built for 100% compatibility with that motherboard)

I rely on RealTemp for my temperature monitoring needs!

One thing to remember is that each program checks for temperature changes at different intervals and rounds differently. Asus Suit II is usually much slower in detecting changes and will usually give the highest temp +1 or so. Suit II is extremely buggy. I only use it for the fan controls

Use realtemp, coretemp or hw monitor. Either one will do the trick.

I don't see where you are getting 10C+ differences. Maybe between each core, but if you look at each core # and compare it to the same # in each one they are never more than 2-3C off, which could easily be due to different refresh intervals. It looks like you are looking at, say core#0 in core temp and saying it is 10C lower than Core#3 in another program. You should only be comparing the same core #'s.

Some update at 1 second interval while others may be 5. Temps change as much as 10C over as little as half a second, so that could easily account for a couple degrees with each program.

Also, it looks like the Asus software is reading from the external motherboard sensor and not the internal core sensors that are being read in Core temp and HwMonitor,etc. That is why it is only showing one individual temp and not all cores. The external sensor will vary greatly from the actual core temps you see in most software monitors. Just go by the internal core temps as seen with the Core#0, #1, etc. Any software that reads from those sensors will be far better than one that is reading from the external sensor. So I'd pick the fastest refresh software that reads the internal core temps and stick with it.

One is CPU temp the other is cpu CORE temp.

Different.

Look at the circle in ASUS Sensors and the circles in the other programs, the difference between the ASUS Sensors and, lets say, HWMonitor is like ~10C.
