Specs: Windows Vista 64, E8600/4GB PC6400
My new computer has an Asus P5N-D mobo. Asus has a CPU temperature monitoring program on the support disk and I was wondering if anyone has any opinions as to it's accuracy?

I've used PC Probe on my last three Asus builds & it's usually comparable to the BIOS readings. I just cranked it up & my CPU temp is reported as 29C. I fired up OCCT for comparison & the temp is jumping back & forth between 28-30C. Core Temp shows the same. I don't trust SpeedFan.

Hi jam. Wow, that's great. Now I am wondering why mine reads most of the time at 39 C. I have an E8600 cpu with a Zalman 9500 heatsink/cooler. Could that be right? My case, NZXT Tempest, has 6 case fans. What conditions do you have to get that low of a temperature?

"What conditions do you have to get that low of a temperature?"

I sure as heck don't have 6 case fans...lol! That's total overkill & if they're not configured properly, they'll just fight each other.

I have a single 120mm exhaust fan in the rear, that's it. And my PSU also has a 120mm fan. My case has a duct in the side panel that I have adjusted to approx 1/4" above the CPU cooling fan...that assures that it's always pulling in fresh air, not recycling warm case air. I'm using the stock AMD HSF & my CPU is overclocked from 2.0GHz to 2.5GHz. Avg room temp is about 20-22C.

OK jam. This case comes standard with those fans. They refer to it as "Airflow King". 2 120mm intakes in front, 2 140mm exhaust on top, 1 120mm intake on the Left side panel and one 120mm exhaust at the rear. My room temperature is around 70-72 F. This thing is quieter than my old computer. The burn tests that they performed indicates idle temps around 41 C. Seems they have already taken into consideration the flow process to come out like this, don't you think? IDK.

Frankly, my first move would have been to remove the two front fans and the side panel fan; probably would have unplugged the front 140mm on top too.

I wonder how much testing the folks at NZXT went through to determine the need for 6 case fans. Or, if they simply determined that a half dozen huge fans was a good idea when trying to capture a hunk of the gamer market.

It's still my opinion that natural unimpeded airflow thru a case is the secret to air cooling. Bottom line for any configuration is that a cooler case interior equals a cooler processor.

You have 6 case fans & a Zalman & your CPU temp is 39C. I have one case fan, a stock HSF, a 25% overclock & my CPU temp is 29C. You tell me.

Both of you make good valid points. I will experiment and disable some fans, as steve suggest and see how that works out. Thanks guys.

Compare you results to Real Temp.. its a
freeware program I use it and I thinks fairly
accurate

Thanks mikekay1. I have tried Real Temp, but it does require a calibration of sorts. My calibration caused my idle readout to go from 25 C to 43 C, so I am not sure what the calibration should be for my setup. I have some wrong information in my signature. CPU should read E8500, not E8600 as shown. I also noticed that when my room temperature was at 66 F this morning, my idle temp. dropped about 6 C. I don't think I have a problem. Just can't trust the readouts with these programs.
