Winning the Hardwarezone's Four Stars Best of the Best Award from Hardwarezone Singapore

" The HIS Radeon HD 4870 IceQ 4+ Turbo, with its new and improved IceQ 4+ cooler also performed admirably. It recorded 61 degrees Celsius, making it the coolest card here and among the Radeon HD 4870 group in particular......All things considered, this is a solid card and is easily one of the better Radeon HD 4870 cards that we have tested. It provides a marked increase in performance, and manages to significantly reduce operating temperatures. "

The return of The Legend - IceQ 4+ Cooling Technology!

HIS IceQ 4+ is the revision of the 4th generation of IceQ cooling technology, which is endorsed by the media worldwide. Thanks to the newly designed dual heatpipes and heatsinks, the cooling capacity is increase by up to 60%! Thicker spreader and heatpipes are used to allow a more even heat distribution among the fins. Spreader is the metal base of the heatsink. In IceQ4+, 8 mm instead of 6 mm diameter heatpipes are used to enhance thermal transfer efficiency.

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, 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.

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.

IceQ 4 - Dual Heatpipes (6mm diameter)	IceQ 4+ - Dual Heatpipes (8mm diameter) Redesigned layout with thicker heatpipe and increase the cooling performance by up to 60%!

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.In IceQ 4+, the memory and VRM components are directly cooled by a metal base plate.

Crossfire Advantage:

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.

Single Card Setup	Crossfire Modle Setup

The demonstration shows that the IceQ 4+ does outperform the 3rd party cooler in closed environment. 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.

Quieter - Significantly reduce noise level and extend service life

Even through the cooling capacity is increase by up to 60% when compare with IceQ 4 Cooler, the noise level is still supress to the minimum, nearly half of the sound level when compare with AMD reference cooler!

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