"We like the HIS Radeon HD 4850 IceQ 4 TurboX, we like it a lot in fact. It combines one of, if not the best third party cooling solutions we've tested with a healthy factory overclock and a custom-designed PCB that builds upon the reference design's power circuitry in particular. As you know, we're not particularly impressed with the stock cooler on the Radeon HD 4850 – it's not that it is a bad design, per se, it just doesn't do a good enough job of keeping the card cool without being a little on the noisy side. Without a doubt then, if you're in the market for a Radeon HD 4850, we'd recommend looking at one with an after market cooling solution."
