GIGABYTE X99-Designare EX (Intel X99) 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).

Thermal Testing at 4.5GHz Overclocked 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 X99-Designare EX is very high quality, and maximum OCed temperatures even overclocked were 10C lower than on the X99-Phoenix SLI. It could be because of the difference in PCB layers or even copper content, but the X99-Designare EX carries the same components for power delivery as the X99-Phoenix SLI. I was impressed by how the temperature on the rear of the VRM was always lower than that on the front; it shows that the heat is being pulled away from the PCB.

 

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