Product Advantage

HIS IceQ 4 is the 4th generation of IceQ cooling technology, which is endorsed by the media worldwide. Thanks to the newly designed double-slot fans and dual heatpipes, HIS IceQ 4 effectively dissipate the heat from the GPU, thus enabling it for high levels of performance. 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 gamer.

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.
2. Crossfire Advantage
   For CrossFire setup, the fan ensures effective cooling with another card blocking at front.
3. Silent and durable fan
   Significantly reduce noise level and extend service life
4. Dual Heatpipe
   Heat is rapidly transferred from the core area reducing the GPU temperature.
5. UV Sensitive
   IceQ4 will glow under UV light.

Faster - 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:

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.

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
