ASRock Fatal1ty X99 Pro Gaming i7 Motherboard Review

Thermal Imaging and Power Consumption

 

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 that 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 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 front side and backside of the PCB. Keep in mind, the majority of the heat from the VRM goes into the PCB as it is a giant soldered on copper heat sink. A larger difference in temperature between the back and front of the PCB points towards a more effective heat sink.

 

Thermal Testing at Stock Speeds:

 

The image on the left is always at idle, and the image on the right is at load. During ALL TESTS, fans above the VRM that cool the CPU cooler's (Corsair H110i GT) radiator are turned on to high (12v).

The VRM on the Fatal1ty X99 Professional Gaming i7 is overbuilt, which is great for overclocking. The hybrid digital PWM does very well with phase shedding in light load situations and shifts to utilizing all phases when under a heavy load. Overall VRM performance is great, and the heat sink does a decent job of cooling the VRM.

 

Anything under 60C is great, 60-80C is acceptable, and anything above 80C is a bit worrisome (if at stock).
