Club3D decided to equip its Radeon HD 7850 royalQueen with their CoolStream cooler. This one isn't really impressive, Club3D keeps things simple here. In this case you get  one eight millimeter copper heatpipe in direct contact with the GPU, the usual aluminium fin stack and a single 85mm PWM DC brushless ball bearing fan. This one is manufactured by Power Logic and carry the model number PLA09215D12H.
The manufacturing quality is not excellent but still good, but one can see that Club3D is optimizing the price.



A closer look at the PCB shows that Club3D equipped its card with the reference design PCB. The power design is left untouched, all components are the same as on the reference card. In this case you get a so called 4+1+1 phases power design where four are for the GPU, one for the memory and the last one for the PLL.
Checking the voltage regulation chips we find a four-phase analog controller NCP5395T from ON (ON Semiconductor) for the GPU and two single-phase controllers ANPEC APW7165C both memory and PLL.



The memory chips used are made by Elpida and carry the model number EDW2032BBBG-50-F. They are specified to run at 1'250 MHz (5'000 MHz effective).
