PRODUCT PICTORIAL & WALKTHROUGH
Let's take a virtual walk around HIS's IceQ4 version of ATI's Radeon HD4850.
Starting off at the cooler, the 70mm turbine fan pumps quite a significant amount of air even while at idle, but still remains exceptionally silent. When the videocard's load and heat output increases, the cooler fan will ramp up to a higher speed as well. But even through hours of thrashing this card through benchmarks, the fan barely came off of idle. In fact, once I thought the fan wasn't spinning so I poked the fan with my finger to try and manually spin the fan up again. This lead to my fingertip getting clipped rather abruptly and sent my running off like a whimpering puppy as I went to fetch some bandaids.
The copper dual heatpipe heatsink cools all eight GDDR3 overclocked memory modules along with the overclocked RV770 VPU core. The cooler has a lot of surface area to cool all chips accordingly and led to a stable gaming environment with no artifacts. Under the plastic cover are 36 copper fins that span a half of the length of the card and allow for the lower amount of airflow to extract as much heat as possible.
Once the heat is collect, it is exhausted directly out of the case and thus removes 80-90% of your videocard's influence on internal case temperatures. and with the amount of heat this videocard produces while benchmarking, you will be glad that heat is not being radiated into your case.
Below the exhaust port are your two DVI ports, and a video-out port for connecting the supplied component dongle or the s-video converter.
Turning the card over exposing the boring, yet necessary part of the videocard where the enormous cooler is anchored to the card via no less than nine screws through the PCB. This leds to a very rigid and well built card. Build quality is second to no one.
