ASUS P7P55D-E-PRO sporadic temperature sensor readings.

post #1 of 2
Thread Starter 
I'm just noticing this unwelcome behavior for the first time today.

My CPU fan is plugged to the PWM controllable fan header. It runs from ~1000rpm when idle to ~2000rpm when on full. I'm web browsing and noticed the fan running up a bit with nothing seemingly going on in the system (no cpu load). So I opened CPUID HW Monitor and RealTemp to watch...

Core temps are all low, between 28 and 32c, which is pretty much expected, but the temp sensors on the MB are giving off sporadically high readings every now and then, jumping from 30'ish to 99c and immediately back again. Since the CPU fan speed is tied to those sensors, its bumping up and down in response.

I've noticed in the past that the Max values reported for those sensors in HW Monitor do look bogus (198c, dont think so), but it's never affected fan speed before today. I suppose the jump up/down has happened too fast in the past to influence the fan speed. But it seems like the spurious temp readings are latching in for longer and are starting to impact the fan speed.

Not long ago, I installed a new GTX670 and new 1600Mhz memory, changed the mem speed and timings in the bios when upgrading the memory. Otherwise, I haven't changed anything for many months about how its setup.

I'm wondering if anybody else has seen this sort of thing with an ASUS P7P55D-E-PRO and found some way to fix it?

Weeks ago, this problem resolved itself I'm happy to say.

But then just today, I noticed it again? After waking it from sleep the CPU fan kept bouncing up and down when at idle. HWMonitor showed the motherboards sensor reading bouncing up and down, the i7 core sensors don't bounce. Put a little load on the CPU and the sensors and fan settled in at reading/rates appropriate to the light load, return to idle, bounced up and down again.

Then i had the brilliant idea to restart the system. After a restart, seems to have resolved itself again. Ok, a minor nuisance, when in doubt restart.
