Question regarding Voltage and Heat readings

Ok so as per recommended I installed an Antec Truepower Trio 650w last week and immediately had improved results. However I had a few questions regarding some readings I'm getting via speedfan.
I get three Voltage readings, my core voltage, my +12v rail voltage and my 3.3v rail voltage. My +12v rail stays at 12.25 and my 3.3v rail stays at 3.30. My question is this, should speedfan be reading any other voltages? And are these readings normal/stable?
Also, I have three thermal readings. One is system, currently reading 33c.
CPU reading 42c (running a Pentium D 2.66ghz OC to 3.00, I'm told but not confirmed Pentium D's have some issue where they only have one thermal reading as opposed to the newer cores that read 2 respectively.) And the one that really has me confused, an AUX reading that reads -48c O.o
I also noticed that I have 4 speed settings just below the fan rpms and thermal readings. The third speed setting was defaulted at 35%. If I bump it up even one click the AUX thermal reading shoots through the roof to upwards of 150c. I'm really confused by this and hoping there are some answers out there.

One other thing. After running with my new power supply and normal nightly shutdowns I ran into an issue today. Upon hitting my case power button my fans lit up and spun, and immediately shut off. It happened again 2 or 3 more times until it finally stayed on and booted to windows. After a few seconds of loading my start up programs it shut down. I've managed to get it booted and running and tested out a few programs and it hasn't shut down yet. However I am somewhat concerned about this.

Re: Question regarding Voltage and Heat readings

I suggest you try some other monitoring programs also and evaluate them on a majority rules basis


everest home eidtion


PC Wizard

Sensorsview Pro

"Core temp monitor" >>>should should you the temp of both of your cores ???


you can google search for these and keep us posted

Re: Question regarding Voltage and Heat readings

I've tried Core Temp it doesn't recognize my core as an Intel core and won't even run.

Re: Question regarding Voltage and Heat readings

Thanks thats good to hear. How about my thermal readings? Cpu core idles around 40c. Under load its usually 54-56. I have a Zalman CNPS9500 installed with Arctic Silver 5. And my GPU is an Evga Nvidia 7950gt ko stock settings. Idles at 50c and upwards of 64c under load. Granted this case absolutely bites for airflow. I usually see a decent few degrees increase when I put the side panel on.

Re: Question regarding Voltage and Heat readings

as long as your cpu does not his 62c (thermal max of cpu) you should be fine as for the video card that is ok but it could do with uped fan speed.

Re: Question regarding Voltage and Heat readings

When I ran Orthos last week my CPU temps reached 60c, never went any higher. For some reason even with my GPU fan pushing 100% it still gets pretty hot.
