Famous for German enthusiast Der8auer has created a liquid cooling system for the NVIDIA RTX 5090 Founders Edition. The task is complicated by the design of the new video card.
As you know, the RTX 5090 FE electronics consists of three printed circuit boards and uses liquid metal as a thermal interface, technical differences make it difficult to create or modify liquid cooling systems for it. The Der8auer prototype managed to reduce the temperature of the GPU from 73.8°C to 43.8°C.
The water block is made entirely of copper, including the cooling plate and outer cover. It was designed as a proof of concept and is minimalist yet neatly designed. The transparent glass cover allows you to see the liquid flowing past the plate. The cooling element itself is made of 14mm copper and has multiple passes to cool the entire large GB202 chip.
The liquid block occupies two slots and has the same length and height as standard cooler RTX 5090 FE. This is a necessary step to take into account the length of the ribbon cable connecting the video card outputs to the main board. This cable probably cannot be folded without damage. If not for it, the unit would probably look more like a conventional liquid cooler.
Despite the difficulties in design, the water block demonstrated exceptional results during testing. Der8auer recorded a 30°C drop in GPU temperature and 38°C drop in memory temperature compared to standard cooling. The enthusiast intends to produce for sale RTX 5090 FE liquid coolers, but notes that before that, it is necessary to solve the problem reliable fastening of the system in the slot.
Perhaps his client will be a girl who adapted a household air conditioner to cool video cards. She wanted to use it to cool her NVIDIA RTX 5090 FE, but there are currently no commercially available liquid systems for this video card.
