HIS HD 4830 IceQ 4 512MB (256bit) GDDR3 PCIe

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.

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.

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:
