AI SUITE

While the performance of the Fusion APU puts it in the low power nettop category, the E35M1-M Pro is a full featured motherboard complete with an UEFI and Asus' latest version of AI Suite to tweak settings to your liking.


TurboV menu.

Through the TurboV utility, one can change both the frequency and voltage of the APU.


Fan Xpert menu.

The Fan Xpert utility gives you the same options as in the UEFI, but with the instant gratification of changing fan settings on the fly from the desktop. Of the two, we do prefer the UEFI as Fan Xpert oddly only allows a minimum CPU fan speed of 64%.

Fan Control

The board has two fan headers, a 4-pin PWM header for the CPU fan (works with both PWM and DC fans), and a 3-pin DC header for the Chassis fan. Both are controllable, 20~100% for the CPU fan and 60~100% for the Chassis fan. In real life the fan speeds adhere closely to the settings entered in the UEFI or in Fan Xpert.


SpeedFan screen with correlations noted.

SpeedFan offers a better alternative as it gave us full control over both fan headers. It allowed us to turn fans off completely; no silly minimum limits for the hardcore silencer. It also had the same fan and temperature sensor readings as Asus' PC Probe utility.

NOISE & COOLING

The most prominent visible feature of the E35M1-M Pro is its massive heatsink covering both the APU and FCH, so you're probably wondering whether it can be run passively.

The board ships with a terrible-sounding fan with tonal tendencies. It started at about 1900 RPM (18~19 dBA@1m) when we set the fan control mode to "Standard." Manually set to 1000 RPM (45% in the BIOS or SpeedFan), it was practically inaudible at one meter's distance. At that speed and with the board on full load in an open testing environment, the GPU temperature stabilized at 68°C. The exterior temperature of the heatsink measured just 43°C at its hottest point, and the VRMs stayed below 50°C.

We would wager that any microATX case with just a single fan blowing across it indirectly would keep the board cool enough. It does not require much in the way of airflow, especially if you don't stress the GPU.
