Will the new Nvidia GPU cooler design prevent the build up of dust from clogging the cooler? It should certainly be easier to blow out the straight through cooler on the right side of the card with pressurized air. In the same vein, why don't the GPU fans have screens on them to block dust from the fan intake? I actually have two screens on the intake for my CPU AIO, vacuum them probably every month and dust still builds up on the radiator fins and needs blown out.
Despite periodically blowing out the CPU radiator fins with can of pressurized air, when moving to a new CPU (generally upgrade every 4 years) I've been shocked at the the amount of dust stuck in the radiator when flushing it with water in the sink.
As a 3080 may well max out my 60hz 4K monitor, it may make sense to purchase one with a closed loop AIO cooler attached this time around.
