AMD Phenom II X4 - CPU Fan / Temp Question

Specs: Windows 7
I recently got a new system. It's packing an AMD Phenom II X4 925 CPU running at 2.8ghz.

When I was checking the system out using SiSoft SANDRA, and opened up the motherboard properties, it told me two things:

a) I had a system fan spinning at 86RPM, which it said was failing.

and b) The VCore was "higher than maximum". It reports it at 2.16v, and a website I found says 1.5v is "normal".

Also, the system temperature is "idling" (just at the desktop with nothing running) at 36C. With World of Warcraft running in the background, and Firefox, it is running at 45C.

The same website as above reports the max operating range at 55-71C.

The CPU fan is spinning at 4,167RPM, and the board temp is currently 47C, and the CPU temp is 42.50C, and CPU2 reports as 46C!

I am new to Quad-Core Processors, but these numbers scare me. Should they? Should I pack this up and return it to the store I bought it at?

I'm going to ask a dumb question, but 86RPM (was 69 in idle) is a fan barely operating right?

How should I interpret this? Thank you for your time.

"How should I interpret this?"

Software error. Don't trust SANDRA. Did your motherboard come with monitoring software? If not, it *may* be available at the board manufacturer's website. You can always look in the BIOS too.

I don't know why SANDRA is reporting wrong info (i use it in different systems and it display wrong info), try cpu-z or everest.

It's been a long while since I've had to do this and I forgot about the mobo diagnostics. I went into the BIOS and peeked around, and this is a very limited BIOS as far as what I can see or change. I could not find any temperature monitors, or fan controls/speeds, anywhere in the BIOS.

Running the diagnostics did scan checks of the CPU, Memory, HDDs and the optical drives and boot paths. That's it. They all passed.

CPU-Z reports the core voltage as 2.16v, the same as SANDRA said.

I downloaded and installed the trial version of Everest, and it did not recognize the motherboard in this, so I had it do a full scan to submit to Lavalys, and this is what it kicked back for temp, etc:

This is from a cold start, after running for about 20mins, with nothing but the Windows desktop and Firefox in use.
