System Temp.

[seekermeister]

While working on another unrelated problem, I opened SpeedFan and found that the system temperature was much higher than I had seen before, as can be seen in the screenshot. Currently, I have both sides of the case open, and since none of the component temperatures come even close to comparing, I don't understand how it could be so high, since the room temperature is at normal also.

Is this just some kind of glitch in readings, or is there some else that could possibly be awry?

EDIT: I just checked the chipset fan, and it appears to be running normally, without any noticeable dirt in the HS fins.

I checked the temperatures in SpeedFan's configuration window, and it shows an aux temp that is even higher. I'm not at all sure what the definition of aux temp is, or how it might relate to the sys temp?

Hello seekermeister, I don't know what's AUX mean, but I made a search and found this: [Solved] What is AUX temperature? - Other-Components - CPU-Components

Also, you're temperatures are not so low. First one, I guess is the mobo temp, that its pretty high for idle pc.

As I see in you're system specs, you have pretty good cooling system in your pc. Check that you're fans are working propertly. Maybe something is wrong with them, that's my opinion.

Thanks for the link, I guess I can ignore aux temp, but the same isn't true of system temp, which was my main concern. All visible fan are spinning normally. The only one that I can't see is the middle fan on my CPU HS/F, but that shouldn't have any effect on the system temp.

I wouldn't be happy with that idle system temperature even on a really hot day.
Is Fan 1 speed correct? Seems high.
You could try comparing the results using
HWiNFO, HWiNFO32 & HWiNFO64 - Hardware Information and Analysis Tools
or
CPUID - System & hardware benchmark, monitoring, reporting

Yes, it is correct. That is the CPU fans, which I have set on high...but again, that shouldn't have anything to do with the system temp. Fan 2 is the chipset fan, but as I recall, that is the same speed that it has run since I installed the motherboard.

 

[seekermeister]

Wrong again...I rebooted into the BIOS to check the chipset fan speed setting, and while it is set on high, it is the higher speed fan shown in SpeedFan. The lower speed fan is the fan I have mounted on the bottom of the case.

I also checked the system temp and CPU temp while in the BIOS, and while the CPU temp is a little hotter than shown in SpeedFan, the system temp is 5 degrees cooler. I'm accustomed to the CPU temp being hotter in the BIOS, because that has been true on every system that I've built, but I can't remember that might hold with the system temp temp?

I don't believe the temperature in the BIOS measures "idle" system temperature. It also depends what they are measuring after a BIOS upgrade ASUS went from measuring Tcore to Tcase.
The programs I mentioned (which you may have) give a good approximation of Tcore. They provide an accurate Tsystem for my motherboard.

HWINFO agrees with SpeedFan on the system temp, but I'm beginning to think that the temp is invalid anyway, because on one reboot, it read 42 degrees (2 degrees hotter than before), and on the last reboot, it read 49 degrees (9 degrees hotter than original). Since these temp don't seem to change over time, I think that there is a problem with the way that either the programs are reading it, or something awry in how the motherboard is measuring it.

Your last post threw me a bit, because my motherboard is ASRock, not Asus, and I have never flashed the BIOS, so I don't know if it uses Tcase or Tcore. However, I was thinking that Tcore was for the processor, not the chipset...

 

[mjf]

Tcore/case is for the CPU but you just mentioned the CPU above which is why I mentioned it. My mention of ASUS was I had experience with it's confusing BIOS temp measures and ASRock was a spinoff - yes tenuous link.

Is it possible your system temp sensor is faulty. This may be a dumb suggestion but assuming you don't have a thermocouple type thermometer could you use a conventional thermometer to get a sanity check at least - 46 C is hot.

I would suggest flashing bios if you haven't done that before. Also that temps are too high with that cooling system that you have.

I suggest you to check the cpu heat sink, maybe something is wrong with it. :sarc:
