ASUS X99-PRO Motherboard (Intel X99) Review

Temperature and Power Consumption

 

System power usage is measured at the AC/DC PSU (the Corsair AX1200i) which I have connected to another system to measure the test system and as a backup I have a wall meter to verify. The CPU power is measured through the 8-pin connector which is hooked up to a hall effect IC which measures current and puts out a voltage in proportion to the current. That voltage is logged by a National Instruments ADC which logs the DC voltage level, which I then convert into current.

Note on Thermal Images: In the temperature section, we use our Seek thermal imaging camera to capture the surface temperatures of major components on the board; I look at the VRM and then all other things that light up the screen. If there is something to worry about then I will state it, otherwise I will just show the hotter running parts of the board for fun. Unless some component is over 80-90C then there really isn't anything to worry about.

 

All systems will act differently, so I will look for commonalities, such as how far from the VRM the heat spreads through the PCB and the difference in temperature between the frontside and backside of the PCB. Keep in mind that the majority of the heat from the VRM goes into the PCB as it is a giant soldered on copper heat sink. As long as the front of the board is warmer than the back of the board, the heat sink is doing its job pulling the heat away from the PCB.

At stock, power saving features are engaged, I saw only one phase light up during idle conditions to reduce switching losses. During load, at stock, more phases started to turn on, and it's apparent that the PWM is set to high efficiency mode; temperatures are very nice and low during stock tests. Not all phases heat up to the same temperature, instead it's almost like every other phase is turned on to improve efficiency at stock settings.

 

At a 4.5GHz OC, temperatures increased slightly when load was applied. Heat seems to be spread evenly across the PCB area, which is a great sign, and the temperature on the back of the PCB was always at least 2C lower than the temperature on the front. This delta between the frontside and backside of the PCB indicates that the heat sink is doing its job so the heat isn't spreading to the back of the PCB. Overall, we see excellent VRM thermal performance.
