September 5, 2023 The GeForce RTX 4090 with 5 GeForce fans has appeared. Reported by overseas media WCCF TECH. A Chinese PC parts maker called MaxSun has released the GeForce RTX 4090 MGG with five cooling fans in the GPU cooler. At first glance, it looks like a common triple fan, but it has a unique design with two additional small fans on the side. MaxSun GeForce RTX 4090 MGG – Equipped with 5 fans At first glance, it feels like it’s going to get cold, but it’s not. According to Chinese user Hiniku who bought this Gravo, the GPU temperature exceeded 80 degrees Celsius under high load, and the hot spot reached nearly 100 degrees Celsius. GPU: 82.8°C / Hot Spot 98.5°C No manual overclocking, room temperature maxed out at 28°C. When Hiniku checked with other users who purchased the same Gravo, the temperature was even higher than that of Hiniku. When Hiniku contacted MaxSun customer support regarding the temperature, he said it was “normal.” MaxSun “Normal” So far, I’ve tested 8 GeForce RTX 4090s, including the Fouders Edition, and the GPU temperature during gaming was 60-65°C, and even with FurMark turned, it was 70-75°C at best. The GPU temperature exceeds 80 degrees Celsius and the Hot Spot is close to 100 degrees Celsius, which is by no means an appropriate temperature. Maybe MaxSun’s customer support doesn’t know what they’re talking regarding, or their definition of “normal” is a bit abnormal. Hiniku asked for a refund, but MaxSun initially refused. However, following a lengthy 600-word persuasion, MaxSun complied with his request and granted a refund. This Gravo has less cooling capacity than other manufacturers’ products, and it looks like a tinsel. Fortunately, this Gravo is only sold in the Chinese market. If it was sold worldwide, it would have been taken up as a big problem. For reference, the temperatures during games (GPU usage rate 100%) on each manufacturer’s GeForce RTX 4090 are as follows. GeForce RTX 4090 – In-game temperature GPU temperature is 58-72°C, Hot Spot is 67-81°C. There is not one blasting grabo like MaxSun. MaxSun GeForce RTX 4090 MGG, what a shoddy graphics card…
