Hello, I am a lurker and occasional dabbler in home computer builds so consider me a Novice. I have an older i7 920 system that I am tinkering with. MoBo is P6T with the most up to date BIOS 1403(?) IIRC that used to Run vista 32bit but recently had a clean install Win 7 64bit to take advantage of the extra RAM I added. I am using an Antec 900 case from my original build.
One of the areas I am focusing on is core-temperatures, so I've been running Open Hardware Monitor overnight with Seti@home.
One thing I noticed immediately was the fans behaved strangely. Some nights, it would ramp up, then quickly ramp down. Other nights, it would never ramp up at all. Sometimes it would ramp up and stay up, keeping my core temp at 80degrees C (yes I know its a bit higher than recommended but that's part of my project) The 3rd scenario was obviously was I wanted to build on.
The stock Intel i7 Fan idles at 930-950 rpm.
I've played around with QFan, SpeedFan and it always stumped me. Until I found Asus own Xpert fan (my older P6T only supports ver 1, not the newer xpert fan2)
The first Calibration test I did revealed what seems like the source of the problem. The CPU fan defaults to idle speed of 950 rpm when it's suppose to be at 100% even though it ramps up nicely up to at 70% to 1400 RPM. My CPU fans stable top speed seems to be at around 2,000 RPM as i've seen it sit at that speed occasionally.
What's stranger, I managed, for a brief period, calibrate the fans so the the CPU fan ran at 2,000 RPM at 100% and this seemed to work when I ran Prime95, except the fan speed cut back to idle nearing the end of Test #3 and recalibrating after that showed the same weird fan speed curve. So it was a brief moment of hope that was dashed, but it seems clear that something is not right as the fans COULD work properly, even for a short time.
Trouble Shooting
1) Qfan is disabled, but FanXpert seems to be able to see Qfan settings as it preloaded my Turbo once when I ran it with Qfan on, so I don't think that's the issue.
2) I have MSI GTX760 installed with Afterburner 3.0 (BETA) so I suspected maybe that's conflicting with the CPU and chassis fan, so I restarted making sure not to boot it (it's not an automatic start up program) and got the same results.
Is my MoBo just not working properly?
Are my fans defective?
Is there another program/feature I forgot to turn off that's interfering?
Is it maybe the GPU afterall?
Any help/insight would be appreciated.
