As noted earlier, the GTX 980 Gaming 4G graphics card features MSI's famous Twin Frozr V cooler with a total of four heatpipes, where three measure 8mm and one comes with a diameter of 6mm. Apart from that, there are two 100mm fans which cool the large heatsink connected to the nickel-plated copper base plate. As a part of the MSI Gaming series, the this particular cooler comes with a red on black color scheme and the overall build quality of the cooler is just great.
The MSI GTX 980 Gaming 4G graphics card, or to be precise our sample
of it, allowed a maximum stable overclock of 1'600 MHz for the GPU and 2'197 MHz
on the memory side. To determine stability we used 3DMark. With these clocks we had to feed the GPU with 1.21 Volts and the
memory ran at stock voltages.
Like most of MSI' recent high-end cards the PCB has been completely reworked
and the power design beefed-up. The custom PCB features 10+2+1-phase design. In
this case then phases are taking care of a stable current supply to the GPU, two
phases take care of the memory and an additional phase is in charge of PLL.
Looking for the voltage regulation chip we find an NCP81174 for the GPU, an
INA3221 for the PLL and an APL1117 for the memory. In case of the GPU MSI is
using high quality SFC phases.

The memory chips used are made by Samsung and carry the model number K4G41325FC-HC28. They are specified to run at 1'750 MHz (7'000 MHz effective).
