HIS 6870 IceQ X Turbo X

Our second card from HIS is the Radeon HD 6870 IceQ X Turbo X. The HD 6870 IceQ XTX is the highest factory overclock card and, despite the IceQ moniker, doesn't feature a giant blower fan like the IceQ does. Instead, it features a centrally mounted axial fan with full length shroud, colored in a very cool looking aqua-marine with darker highlights - and the odd sticker.

Again the back of the card is bare, with the giving very indication of being stock. Like the other coolers here, the four heatpipe monster is mounted using four spring loaded screws.

The heatpipes meet the GPU core via a copper base, and spread out to the ends of the fin array to be cooled by air blown through by the centrally mounted fan. Air exhausts both out of the case and back in to the case, venting from both ends of the card. The memory is cooled by a seperately mounted aluminum heatspreader, as are the VRMs.

The VRMs are indeed unchanged from reference design, the effort HIS have put in here is primarily in binning the ASICs for highest capable clockspeeds and the cooler to handle all that extra performance escaping as thermal load.

If you like blue green, the HIS IceQ XTX is a great looking and well packaged card. Like the IceQ, the IceQ XTX is packaged in a rather unassuming box, but it is adorned with sticks informing you of the potential inside - factory overclocked, 15C cooler and 15dB quiter than reference designs. Along with the tri-fold driver CD and installation manual case, you get a DVI to VGA adapter, a CrossFire bridge and a pair of four-pin Molex to 6-pin PCIe power adapters.
