ASUS A8N-SLI Premium - help w/ temp monitoring

post #1 of 6
Thread Starter 
I'm setting up SpeedFan 4.33 to do temp monitoring and auto cpu fan speed adjustment on my ASUS A8N-SLI Premium motherboard. I'm a bit confused as to what the correct CPU core temp reading is. It looks like it could be 2 different sensors, either the AMD K8 Core Sensor, or the IT8712F Temp1 Sensor. CoreTemp looks like it's getting its values from the former, whereas ASUS's own PC Probe seem to use the latter (same as in BIOS). The difference is that when idle, the AMD K8 Core Sensor reads lower, and on load reads higher than the IT8712F Temp1. Here's a screencap of my system cooling down to idle temps, then ramping up to load using StressPrime2004.



What do you guys think, which sensor is more accurate? e.g. AMD K8 Core Sensor idles at 27°C and on load reaches 60°C, whereas IT8712F Temp1 Sensor idles at 34°C and on load reaches 51°C.

I would go with the one that matches the highest coretemp. Which should match the pc-probe, if I'm not mistaken.

Better safe then sorry is my opinion. BTW I ran an A8N for a couple years.

Actually it's the other way around which is what makes things so confusing... The higher coretemp is AMD K8 Sensor, but it appears that PC Probe is getting its values from IT8712F Temp1. This is on load however, when idle the trend is reversed. So colour me confused!

I absolutely HATE speedfan on a 939 rig. It never seems to give me accurate readings. You can try CoreTemp out. It may work properly, it may not (only 1 out of 3 of my 939 rigs has accurate readings with CoreTemp). Might want to give Everest a try out. Its worked great on all of my 939 rigs. I only use Speedfan if I want to tinker with my Zalman fan on my own personal rig, lol.

hrm, my bad. Well I used pc-probe, when I ran the asus and kept it under 55c 24/7 folding. Being as paranoid as I am, I'd go with whatever monitoring program projects the highest temps, and keep those as low as I could. On the Biostar I use now, I use speedfan, matched it up with coretemp to decide what I thought was accurate, and use that to monitor through surreal's panel in the G15 keyboard.

Good luck.

Wongnog, what does your BIOS read? The temperatures in your BIOS reflect 80% load. Check out Pioneer's suggestion and give Everest a try.

Let us know

Good luck
