HIS introduces the HIS HD 4850 IceQ 4 TurboX 512MB (256bit) GDDR3 PCIe, featuring the 4th generation of the award-winning IceQ cooling technology. Thanks to the newly designed double-slot fans and heatsink, HIS IceQ 4 effectively dissipates the heat from the GPU, thus enabling it for high levels of performance. HIS claim that the IceQ 4 TurboX is "The World's fastest HD4850" and with its GPU and GDDR3 memory clocked at 685 / 2200MHz respectively we're certainly not going to disagree. Sure it might not quite be up there with the 700MHz stock clocked core of its GDDR5 based bigger brother, but with a 60MHz overclock on the core and 212MHz on the memory, the gap will certainly be less pronounced. HIS IceQ 4 is the 4th generation of IceQ cooling technology. It cools down the GPU temperature dramatically when compare with the reference cooler, allow you to maximize your overclocking potential. What's more? The ultra silent and durable fan delivers ultra-quiet and stable gaming environment for enthusiast computer gamer. Efficient transfer of heat outside of computer case cool air is drawn from both sides of the fan and hot air is forced out of the computer case.
This ensures effective cooling when there is another card in front blocking the fan inlet. By expelling the hot air, IceQ 4 removes all the heat generated by the GPU out of the computer chassis, prevents the hot air from accumulating inside and enhancing the overall stability and gives more 19% cooler than other cards. It has ATI Crossfire Advantage, the fan ensures effective cooling with another card blocking at front. Silent and durable fan significantly reduce noise level and extend service life. HIS by tooling up their IceQ4 Cooler not only made their card silent but were able to do that and make the card operate some 20 degrees cooler than others. Dual Heatpipe Heat is rapidly transferred from the core area reducing the GPU temperature. A dual-slot cooling design ensures you can conveniently connect the ATI Crossfire cable to run an ATI Crossfire setup. Other brands' cooler which is greater than Dual-slot cannot run CrossFire Setup in some motherboards. UV Sensitive IceQ4 will glow under UV light. As stated, the plastic cooler is UV reflective, throw in a 5 USD UV cold-cathode and you can get that nice dark ocean blue thing going on. The HIS HD 4850 IceQ 4 TurboX cooler is both silent and offers much better than reference cooling performance. Next to that, it looks quite nice as well, throw in a little cold-cathode UV light and the thing will shine up like it's radiated... lovely to look at it.
As graphics cards go, the HIS HD 4850 IceQ 4 TurboX looks simply awesome. Using a cooler not dissimilar in appearance to the previous generation of Arctic Cooling's 'Silencer' series, a blower fan mounted at the rear of the card pushes air through copper coloured (but most likely aluminium) fins attached to a base plate. As mentioned previously, both the Memory and PLL heatsinks are isolated from the main GPU cooler which is probably a good thing considering how hot the 4800 series cores can get.
At the front of the card you'll find the standard configuration of two DVI ports and an S-Video port bolted to the dual-slot blanking plate. However, HIS have seen fit to gold plate the connections on the DVI ports and also electroplate the blanking plate in a gunmetal black colour. This further improves the aesthetic appeal of the card, which combined with the custom blue PCB, makes it probably the best looking graphics card we've ever seen. The World's Fastest HD4850 - HIS HD4850 IceQ 4 TurboX HD 4850 IceQ 4 Turbo X posting significantly faster scores than the standard HD 4850 and the GeForce 9800 GTX+.
Make no mistake, the HIS HD 4850 IceQ 4 TurboX is the crème de la crème of 4850 series cards. With its superb after-market cooling and fearlessly high factory overclock and nifty little touches such as a custom coloured PCB, gold-plated DVI connectors and an electroplated blanking plate, the card will look at home in even the most high-end PC despite the 4850's mid-range audience.
