@ 2015/06/19ASUS managed to tame AMD's feisty "Grenada" silicon, which powers the Radeon R9 390 and Radeon R9 390X, by announcing two high-end graphics cards based on its new triple-fan STRIX DirectCU 3 cooling solution. The cooler turns its fans off when the GPU is idling (common desktop / light-3D loads), and begins to spool up only under heavy 3D loads. The company claims that this will be the quietest R9 390 series cards you can buy.
The STRIX DirectCU 3 cooler is the same as the one pictured cooling the GeForce GTX 980 Ti STRIX, which we spotted at Computex. It features a huge monolithic aluminium fin-stack heatsink, to which heat drawn from the GPU is fed by four 10 mm thick nickel-plated copper heat pipes. This heatsink is ventilated by three 100 mm spinners. This heatsink has contact bases even over the card's 8-phase VRM, and a base-plate that draws heat from its 16 GDDR5 memory chips, that make up 8 GB. The R9 390 STRIX offers factory OC of 1050 MHz (vs. 1000 MHz reference); while the R9 390X STRIX offers 1070 MHz (vs. 1050 MHz reference). The memory ticks at 6.00 GHz on both cards. ASUS didn't announce pricing.
