Rossy:
A few comments:
Attached is my HWMon screen. Notice that I do not show any voltages or fan speeds. I'd like to see my voltages and fan speeds, but am clueless enough that I can't figger out how to do that. Can you help me or do you simply have a more advanced version of the program?? Mine is version 1.14.0 and seems to have NO configuration options. Help? Where exactly did you get that version? Was it free?
Notice I have HD temps in my screenshot and you don't. Don't know why on that either.
On to your screenshot:
I see you have a Pentium D. Just going from memory, don't they tend to run hot?? I don't know offhand if 52 is unusual. My Core 2 Duo is always in the low 40s or lower.
I see your fans are turning pretty high (compared to my PC). Are they single speed fans or do they change speeds according to internal temps? Some fans can be adjusted to always run faster through a manual switch.
I have to believe the AUXTIN reading is bogus. How could you have any part of your PC operating at 6 (43 fahrenheit) unless you are outside??
Don't know where the SYSTIN monitor is, but that looks quite low.
ACPI: I know what the acronym means, but I don't know exactly where or what that is measuring. Appears acceptable temp.
Radeon temps appear quite low.
General opinion: Google Pentium D and find out if they are known to run hot and if 52 is excessive. There were some Pentium models that were known to be furnaces and I think it may have been the D models.
Make a spreadsheet or Word doc and monitor temps periodically so you have a baseline by date. Expect higher temps in summer if ambient temp is higher then.
Download a system utility "stress tester" type of free app that can make that Pentium D really sweat so you have an idea of how hot it can get. Google acceptable Pentium D ranges. 52 may be very acceptable and beware of relying on fingertip in a wake as an accurate indicator.
Possibly locate another temp tracking app as the 6 degree reading on that one location makes you wonder about the overall accuracy.
I notice your 12 volt line is at about 11.3. I would track that as well. That's lowish, but I think still within acceptable ranges. If it got down to say 11.0, I might worry. Maybe it is transient as those things do move around.
Help me out on where I get your version of HWMon.
