It was earlier reported that the non-reference high performance Radeon HD 4870 graphics card, the PowerColor Radeon HD 4870 PCS+, faced a BIOS glitch (covered here) that affected its stability. Barely days after Chinese website Expreview reported this, PowerColor posted a revised BIOS on their website. Expreview notes that the BIOS didn't quite fix the fan speed (as in up the maximum speed limit), but makes the fan operate at erratic speeds or "zipzip" as Expreview notes. The fan-speed sensor graph should give you a better idea:
