She probably weighs over 15 kg
Video cards with passive cooling — a great rarity today. Therefore, some enthusiasts create such solutions with their own hands. A user of the Reddit forum with the pseudonym Everynametaken9 seems to have decided to outdo everyone at once and created a passive cooling for the GeForce RTX 3080. One that clearly weighs several kilograms.
At the heart of the cooling system, if you can still call it that, is a giant copper block measuring approximately 305 x 76 x 50 mm. It is unclear whether it is whole, but its mass may reach approximately 10 kg. Plus, it has more than a dozen conventional processor coolers installed, probably each weighing about 500 g.
Of course, such a video card cannot be installed in the case, but can be connected to the motherboard via a riser.
How effective this solution is, unfortunately, is unclear, since the author has not even connected the card to the PC yet. But remember that the RTX 3080 consumes about 350 W in games.
