Engineers of HIS Company has used a proprietary cooler IceQ which is very similar to “reference” turbine one, but has a number of improvements. We have already described it in review HIS 7870 IceQ 2GB GDDR5 PCI-E DVI/HDMI/2xMini DP. Graphics card of installed cooling system takes only two expansion slots and has a length of 300 mm. Thus it is perfect for usage in conjunction of AMD CrossFireX, as the efficiency of its work is not affected by the closeness of another graphics card, and hot air is expelled outside the case.

The cooler consists of a turbine and copper base radiator (35 x 28 mm). This feature helps the uniform heat distribution over the entire area of the heat exchanger. Contact with GPU is performed via thin layer of thermo-interface. The radiator is collected by 29 nickel aluminum plates which are located along the PCB.

For more uniform heat distribution over the entire radiator area four nickel copper heat pipes are used. Last two have diameter of 6 mm and central - 8 mm. Heat pipes are firmly soldered to the aluminum radiator and to the basis. However its coverage contributes to a longer service life as it effectively reduces the impact of corrosion processes.

In addition, the radiator has mounted thermo-gaskets, which are designed to efficiently transfer heat from memory chips to the copper basis of the cooler. Unfortunately, the cooling system is not directly in contact with the force elements. Their cooling is ensured by the cooling air flow.

All this construction is covered by black opaque housing. And from the edge there is fixed radial fan (turbine) with diameter of 76 mm. It has a 4-pin connection so the speed of rotation is controlled by PWM modulation.

We offer to go directly to the test of the cooling system of graphics card HIS R9 270X IceQ Boost Clock.

HIS R9 270X IceQ Boost Clock (H270XQ2G2M)

In automatic control of fan speed at maximum load the graphics core warmed up to 74°, and cooler (as indicated by the monitoring) operated with 47% of its maximum capacity, that is approximately 1665 rpm. The noise level can be described as lower the medium level. It was quite comfortable for continuous operation near the PC.

HIS R9 270X IceQ Boost Clock (H270XQ2G2M)

After the forced increase of fan speed to the maximum level, the GPU temperature was 53° and cooler (as indicated by the monitoring) was operated with rate 3154 rpm. This result indicates good power reserve of his cooling system. In this case the noise level increased up to medium level and was quite comfort. 

HIS R9 270X IceQ Boost Clock (H270XQ2G2M)

In case of load absence, due to energy-efficient technologies the operating frequency of the graphics core and memory automatically fell down. In this mode the GPU temperature did not exceed 33°.
