Product Advantage

HIS IceQ technology is endorsed as the most efficient cooling technology among the current mainstream graphic cards' series. HIS IceQ can actively draw the air inside your PC case to cool down the card, and blows amounts of hot air out of your case, dramatically decreasing the GPU temperature together with your PC components. HIS IceQ is also UV sensitive, enhancing the gamers' UV light case.

Heat transfers rapidly out of GPU and reduces temperature faster.	Cool down the droom to overclock and run chip faster; provides more headroom to overclock and run faster.	Operates with lower noise level than original cooler.

1. 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, such as in CrossFire setup
2. Crossfire Advantage
   Ensure you can conveniently connect the CrossFire cable to run a CrossFire setup.
3. Silent and durable fan
   Significantly reduce noise level and extend service life
4. Isolated heatsinks
   memory and GPU heatsinks are completely separated, preventing any heat transfer from GPU to memory. Memory heatsink is actively cooled by air stream from main cooler.

Faster

Turbo-charge your gaming environment
HIS take an already great product and make it better. The IceQ Turbo models are bios-overclocked out of the box. For the TurboX models we push the core clock even further to its limit, deliver the ultimate gaming experience!

Turbo - You can benefit by a manufacture pre-overclock graphics card with the balance of the best performance and cooling effect.

TurboX - You can benefit safety by a pre-overclock graphics card with one of the fastest overclocking performance amongs its peer, with the balance of the best performance and cooling effect.

" HIS HD4850 IceQ 4 TurboX is the world's fastest 4850! "

" The factory overclock is a real push on the HIS HD 4850IceQ4 TurboX to compete with its "rival " 9800GTX+......We have a competetive scenario. In the 3Dmark03 HIS overclock was enough to make the 4850 faster than the 9800GTX+......for GRID it enlarges even more the meaninful adavantage of the 4850 (about 20%). "

Heat transfers rapidly out of GPU and reduces temperature faster
In order to improve the power capacity, we have changed from simple extrusion heatsink to stacked fins with bigger surface area to improve the heat transfer efficiency significantly. Thicker spreader and heatpipes are also used to allow a more even heat distribution among the fins. Spreader is the metal base of the heatsink.

" And the winner is HIS HD4850 IceQ4 Turbo. Among the other cards, only IceQ4 cooling system manages to lower the heat of 4850 GPU to a level which we have been expecting for a time. HIS has the best solution for cooling and power consumption with " - Darkhardware.com

" The cooling effect is much better than the reference cooler, allow you to maximize your overclocking potential.  " - PC Market

Cooler - 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, such as in CrossFire setup. Memory and GPU heatsinks are completely separated, preventing any heat transfer from GPU to memory. Memory heatsink is actively cooled by air stream from main cooler.

Cooling Performance - IceQ 4 vs Single Slot Cooler

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. The more crowded the chassis, the greater will be the impact. Following charts illustrate the impact on cooler performance:

The demonstration shows that the IceQ 4 does outperform the 3rd party cooler in closed environment. The improvement in cooling effect is even more noticeable when a board is placed in front of the graphics card, such as in Crossfire setup

Quieter - Significantly reduce noise level and extend service life

" HIS has done an excellent job on the 4850IceQ4 - besides the quality of the card the fabulous cooler ICeQ4 is efficient and silent and the factory overclock offers a fantastic performance. " - ForumPC (Brazil)

" With the ICEQ4 cooler you can expect roughly 40-41 dB at peak GPU usage (fan RPM will be higher when GPU is hotter " - Guru3D

" 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. " - Overclockercafe.com

HIS IceQ is also UV sensitive, enhancing the gamers' UV light case

" 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 ICEQ4 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. " - From Guru3D.com

Crossfire Advantage

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, such as in CrossFire setup.

" We continue to see quite good gains with the HIS offering over the stock Sapphire one. Moving to Crossfire under Far Cry 2 also yields some excellent performance increases with 2560 x 1600 becoming playable......This is a great card and if you’re looking for a very fast HD 4850 which comes with a great cooling solution, the HIS HD 4850 IceQ4 TurboX is highly recommended. Now the only thing to decide is whether or not to buy one or two. " - TweakTown's "Must Have" Editor's Choice

What Expert Says

" Among the other cards, only IceQ4 cooling system manages to lower the heat of 4850 GPU to a level which we have been expecting for a time. " - Darkhardware.com

" HIS's cards are often easily identified by the unique cooling solution that the company installs on them - Which is known as the IceQ 3. As you are about to see, this card is no exception. " - HWZone

" To some extent I feel that it should be the rolemodel for all coolers as it is very silent, well designed and very effective. It deserves 5 points. " Hardware-Test "Product of the year 2008" Award

" The HIS is both quieter and cheaper than the Sapphire " - Registered Hardware Recommended

" The HIS card is a viable all round purchase. It performs great, looks stunning, and can be obtained at an extremely competitive price......Even with the aggressive out of the box pre-overclocking the IceQ heatsink managed to keep the toasty RV770 core at respectable temperatures and exhausted the hot air out the rear of the case. Additionally, the cooling configuration is quiet and is more than likely to be almost inaudible in the majority of enthuasiast systems. " - Driverheaven UK
