iCooler x4 Cooling Technology

iCooler x4 features a high performance dual slot cooler. It comes with four 6mm copper heatpipes which transfer heat effectively from the GPU to the internal fins around the central fan. Thanks to the elegant design and smoothness of iCooler fan shroud, massive amount of cool air is drawn from the central cooler to cool down the internal fins and heatpipes directly.

Massive amount of air is drawn from the central cooler
to cool down the fins and heatpipes inside
The fan shroud design optimize for air ventilation
that enhance cooling performance


To provide the ultimate heat conductivity larger surface area, iCooler x4 features four 6mm copper heatpipes which extend directly from the powerful 4890 GPU core. Heat from the 4890 GPU can rapidly transfer through heatpipes to fins that extend beyond the cooler. The optimized iCooler fan shroud design allows air flow to pass in and out and removes heat effectively. Together with the VRM heatsinks, iCooler x4 provides a great cooling platform for HD 4890.

iCooler x4 excels in noise management and
is 10dB quieter than reference cooler
iCooler x4 transfer heat out of the GPU effectively.

iCooler Advantage
  • Faster: Heat transfers rapidly out of GPU and reduces temperature instantly
  • Cooler: Award-winning and performance leading iCooler Technology with enhacement of 4 heatpipe to transfer heat out faster
  • Quieter: 10 dB lower than 4890 original cooler on ATI reference design

Wow, performance is yours...!!
I had this graphic adapter, it's very-very performace of high end graphic card and so amazing!
If You see the price 4890 as same as of 9800 GTX by nvidia
But, 4890 have a 1.4 Teraflops / 4.500 Gigaflops better than GTX 280 by nvidia and the price half of GTX 280...
So, absolutely choose 4890 for your PC...!!

" With the HD 4890 iCooler unit I expect to see some more significant overclocks as this GPU cooler is much more aggressive. Our suspicions were accurate as you can see. We got a nearly 14% increase on the core." - Overclocker Cafe Ediotr's Choice

" Looking in at the side of the card you can see a little better how the iCooler X4 is attached to the card itself. During our testing the card was total quiet with the sound of our hard drive cancelling out any sound the cooler might have made......Would we recommend this card to anyone, absolutely if you are a gamer you can plan on having hours and hours of fun playing games like you have never seen them before.  " - Hi-Tech Reviews Editor's Choice

" Across the board we can see that the HIS HD 4890 iCooler x4 is not only able to beat out the GTX 260, but the more expensive GTX 275 and GTX 285 as well......Noise levels at load are the best on the HIS at load when compared to the other cards here (GTX 285/275/265).
