Nvidia's Prototype Quad-Slot Cooler Had Hidden Fan
Nvidia's prototype quad-slot cooling system for never-released 40-series graphics card has made quite a splash among enthusiasts in the recent months partly because of an unusual PCB mounting and partly because of its size. But the cooler apparently has an interesting wrinkle: it has a third fan inside to boost its performance even further.
@Harukaze5719 has found more pictures of the ultimate GeForce RTX 40-series cooling system published by Hayaka, the owner of the cooler who once wanted to sell it for $120,000. This time around, Hayaka disassembled the cooling system and discovered that in addition to two large fans, it has a small fan inside that is meant to generate additional airflow. It also turned out that the prototype cooling system has 22 heat pipes to effectively distribute heat dissipated by the AD102 graphics processor as well as its voltage regulating module.
PCB placement, 22 heat pipes, and three fans indicate that the prototype of the monstrous graphics card was meant to deliver maximum possible performance at maximum possible power. To that end, we are dealing with a prototype cooling system that is meant to deliver overkill performance for simply the best graphics card available.
Meanwhile, an interesting thing about the current prototype is that it only has one 12VHPWR auxiliary PCIe power connector that can deliver up to 600W of power, so a cooler this large might be an overkill for the board. Then again, if Nvidia's plan was to develop the world's highest-performing air cooler for an ultimate graphics card, then this monstrous unit was a way to go.
Yet, it would be interesting to literally hear a cooling system with three fans one of which is located inside the cooler. While Nvidia's cooling systems for Founders Edition graphics cards tend to be rather quiet, it is unlikely that this particular device aimed at the graphics cards sometimes referred to as 'The Beast' was ever meant to be quiet.
