Sparkle Fan

The idea behind the Calibre cooler is two fans that can be expanded like wings. Aside from the cool looking aesthetic component, we could not measure any difference with our open test platform, though. In 2D applications, the temperature measured 44 °C, while under 3D permanent load it reached 66 °C. The measured temperatures and the noise level of 36.3 dB(A) remain constant, whether the fan was folded or expanded and whether the card was under load or idle.

There are two metal clamps per fan, which hold the folding mechanism in position, like a spring

When the wing is at the correct angle, it latches into the holes

When both wings are expanded and latched, the warm exhaust is widely dispersed
