GIGABYTE X99-Gaming G1 WIFI (Intel X99) Motherboard 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 connect 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. A smaller 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.

The VRM on this board is the same one that GIGABYTE uses on its top of the line overclocking motherboards. That means that the VRM is built for overclocking, and the thermals show this. There are only very slight increases from idle to load at stock speeds, and the temperature on the front is always much higher than on the back of the PCB, indicating that the heat sink and the PCB are doing their job in dissipating heat before it can spread to the back of the PCB.

 

At 4.5GHz, the temperatures on the VRM don't go above 50C, which means the VRM is performing within what I consider totally acceptable ranges. Anything under 60C is excellent, 60-80C is acceptable, and anything above 80C is a bit worrisome (if at stock).
