We have all seen some crazy cryptocurrency mining rigs but the latest ones take it one step ahead by putting several NVIDIA GeForce RTX GPUs under premium cooling. Setups have been spotted by I_Leak_VN which shows mining rigs using premium custom-loop kits and even mineral oil to cool off GeForce RTX GPUs.

The first system that has been pictured includes a total of 10 NVIDIA GeForce RTX 3090 GPUs. The GeForce RTX 3090 is currently the fastest graphics card for mining cryptocurrency, especially ETH (Ethereum). The GPU also requires a lot of cooling to keep it running at a steady phase, especially when you're really pushing those 19.5 GDDR6X memory modules, 12 on each side of the PCB. The rig is massive and is custom-built to house all graphics cards.
