Second version of Radeon HD 5770

We thought the second version of cooler was a third-party solution offered by a tiny minority of manufacturers to stand out in the crowd, but later we found that almost all the major AIBs have adopted it, silently.

So far, the leading graphics cards providers including Asus, Sapphire, HIS, PowerColor, XFX, and Unika have employed the new version with a fresh stock cooler. Therefore, we have reason to believe this is a new cooling solution that AMD officially recommends.

The PCB design is hardly different from that of the first version.

The only difference is the additional inductor at the right bottom.
Both versions of Radeon HD 5770 are set at the same clocks as well.

First version vs. second version

first version taken apart
The first version of cooler features more complicated design, enabling it to transfer the heat directly out of the chassis, which helps a lot to build a good air duct inside the chassis. Besides, a metal bar is included to avoid PCB deformation, and the fan boasts 4-pin PWM connector.

second version taken apart
The new version looks much simpler, which has been used on XFX Radeon HD 4870. Such kind of heatsinks fail to send hot air out of the chassis, which would destroy the heat dissipation efficiency inside the case.

8mm heatpipes look massive on such a small heatsink.
