New top of the line from NVIDIA, the RTX 4090 cards are expected to have the best possible cooling genre to make their 450W power count. But, as a user on Reddit shows, a model with details still little known is using a fan (of the “cooler blower” type, which uses a steam chamber to release hot air in one direction only) to cool the device. The results seem positive, especially considering the speed of this mechanism — which, on the other hand, is quite noisy.
According to user BottleneckEvader, this card features a two-slot design, but it doesn’t have any logos that might give us a clue as to its manufacturer — as a detail written in Morse code translates to “AI Edition”. This GeForce RTX 4090 looks almost identical to a Manli Geforce RTX 4090 fan-cooled graphics card that was rumored a few months ago.
The owner said he purchased the GeForce RTX 4090 in Japan from a vendor not named by US$2,675 (about R$13,875). The graphics card arrived in an unmarked, obscure white box. Aside from the foam to keep the graphics card in place and the triple 8-pin to 12VHPWR adapter, nothing else was inside the box. It didn’t even include a user manual or warranty card.
The part shares the exact specs of NVIDIA’s GeForce RTX 4090 Founders Edition. The power cap is locked to 450W, however Redditor still managed to cram an extra 1,800MHz into memory.
Despite having a fan, performance didn’t seem to be compromised. Benchmarks showed that the graphics card’s performance was within the margins of other GeForce RTX 4090 models.
Under a heavy workload, the fan is very noisy, reaching up to 5,200 RPM. The default fan curve allows the GPU temperature to reach 78ºC, while the memory stays at 96ºC. Using a custom and more aggressive fan curve, GPU temperatures drop to 67ºC, while memory sits comfortably around 88ºC.
