As we mentioned before, the main advantage of HIS IceQ models is the design of their cooler, which blows hot air produced by the video card out the computer case – and later copied by Sapphire. Also, it is sensitive to UV light, so it will grow if you have an UV lamp inside your case.

We disassembled the video card heatsink to take a look, see Figures 5 and 6. While the heatsink from ATI’s reference model is fully made of copper, the heatsink used on HIS model is entirely made of aluminum. It is actually made by Arctic Cooling (

As you can see in Figure 6, HIS added passive heatsinks on the top of each memory chip, feature not provided on ATI’s reference model. If you compare Figure 6 with Figure 4 from our ATI Radeon X1600 XT reference board review, you will see that this video card uses exactly the same design as the reference board.

We couldn’t remove the passive heatsink from the memory chips. As this board follows the reference design from ATI, we guess that it uses four GDDR3 512-Mbit 1.2 ns chips from Samsung (K4J52324QC-BJ12)to give it 256 MB of video memory (512 Mbits x 4 = 256 MB). These chips can run up to 1.6 GHz. Since this video card accesses the memory at 1.38 GHz, there is almost 16% headroom for memory overclocking inside the memory’s specifications. But of course you can try overclock it over its specs. So, in theory this video card has good overclockable memories.

This board also comes with one S-Video cable, one Composite Video to S-Video adapter and one Component Video adapter.
