The menthol is perhaps the secret of high performance cooling? HIS seems to believe in it with the new IceQ X, a custom VGA cooler with a 92mm fan and 4 heatpipes that equips HIS new Radeon cards: HD 6850 IceQ X and HD 6850 IceQ X Turbo. According to HIS, the IceQ X is 13°C cooler and up to 7 dB quieter than HD 6850 reference models.
The HD 6850 IceQ X comes with reference clock speeds (GPU: 775MHz) while HD 6850 IceQ X Turbo is a factory-overclocked card (GPU: 820MHz). Radeon HD 6850 specifications avec reviews are available here.
