GeForce RTX 4090 is rumored to consume 600W of power
Compared with the power supply, how to dissipate the heat of the graphics card may be a more difficult problem to solve. The power consumption of 600W is definitely a daunting challenge for graphics card cooling, and the relevant cooling scheme needs to be determined several months in advance so that mass production can be carried out before the official release. At present, most of the flagship graphics cards still use air-cooled heat dissipation. Under the three-fan and three-slot thickness cooling solution, it is a routine operation to cope with 400W-level graphics cards. However, to solve the heat dissipation problem of the 600W graphics card, water cooling should be added, at least some mixed heat dissipation solutions. AMD has used water cooling on top public graphics cards from time to time over the years, and perhaps Nvidia will follow suit this time.
