Today we are looking at two of the latest graphics cards from HIS, the confusingly named HD7870 IceQ Turbo and the IceQ X Turbo X. Both of these cards feature custom cooling solutions and are supplied in a pre-overclocked state. We have been impressed with the IceQ coolers in the past, especially in regards to low noise levels, so we have hopes that these cards will prove a tempting solution for the discerning enthusiast gamer.
HIS have some of the most dramatically designed coolers on the market. While companies such as XFX and MSI opt for distinguished metallic coolers, HIS have designed their ICE-Q coolers in the past with bright plastic aqua blue and transparent colour schemes. The appearance will certainly split opinion, however technically they are actually in the top 10% of cooling solutions on the market.
Above, the HIS HD7870 ICEQ Turbo and ICEQ X Turbo X. No longer have they bright blue semi see-through coolers. Good move, we say.
