AI Suite 3 CPU Sensor Accuracy

[casper5632]

I am using AI Suite to set up my fan curve. The issue is that the sensor doesnt seem to reflect the actual load of the CPU. At idle it reads in the 30c area. When I run Prime95 the temp goes up to the 48c area, but quickly drops back down to 30c. The CPU is hotter then ever, but the sensor is still reading 30c.

I know that this reading SHOULD be the socket temp which is different from CPU temp, but these temps are inconsistent with the temp on the cores.

That's true, the socket temp is inconsistent with core temps. When one core is very hot, the overall package is quite cool. ASUS works in a mixture of socket temperature and power rate-of-change to make that brief rise in monitored temperature. That's apparently so that fans controlled by that sensor will spin up sooner. The problem is that fans drop back when the monitored temperature drops.

I suggest using a core temp monitor: Aida64 is my choice and there is HWMonitor and several others. Be sure to use only one such monitor at a time - they can stumble over each other trying to all read the same sensors.

I have a water temperature sensor connected to an optional sensor header and use it to control radiator fans. With that socket sensor, I'd get a rush of fan noise with every ripple of CPU power.
