Calibre Fly Cooling System consists of copper or Copper-aluminum combination die-casting thermal base, high-efficient heat pipes and dual cooling fans with 0.2 mm thin cooling fins. When the GPU stars working, the copper die-casting thermal base will quickly take the working heat from the GPU to the heat-pipe horizontally put inside the thermal base, and the heat will be equably and rapidly spread to the left part and right part of the copper die-casting thermal base, at same time, the two circular heat pipes also quickly bring the heat from GPU to the 0.2 mm thin cooling fins, now the strong wind pressure and airflow made by two cooling fans take all the heat out of the cooling module. This Cooling System developed by SPARKLE itself can get the most heat exchange area in a limited space, guarantee a highly efficient cooling effect. Besides, the cooling fans of the Calibre Fly Cooling System can be adjusted aslant, so not only MOS circuit on the PCB can be cooled efficiently, motherboard temperature also dropped significantly, the whole cooling efficiency can be raised too.
According to the cooling test data provided by SPARKLE, when tilting the two cooling fans of the Calibre Dual Fly Cooling System 15 degrees, the GPU, video memory and MOS working temperatures can be 13, 4 and 10 centigrade degrees lower than the reference cooling fans. The chassis environmental temperature also dropped by 5 centigrade degrees. At the same time, compared with the 34dB working noise brought by ordinary graphics cooling fans, the Fly Cooling System exclusively provided by SPARKLE has obvious advantage, its working noise only reaches 30dB. (Compare with reference design GeForce 8800 GT)
