SilverStone IceMyst AIO CPU Coolers Feature Stackable 60 mm Fans to Cool Around the CPU Socket | TechPowerUp
 
A drawback of liquid-cooling your CPU has been to leave the other hot components around your CPU socket without a source of passive airflow. SilverStone is planning to address this, with their IceMyst line of AIO CPU coolers. These coolers feature puck-shaped pump-blocks, their top covers come off, so you could telescopically stack up a few fans. Each of these 40-50 mm fans comes with an 8-shaped frame, with one half of it stacking up with the block and providing the rest of the frame with 360-degree mobility, and the other holding the motor and impeller in place.

You can position them anywhere around the pump-block, so you can direct airflow to components such as the memory slots, VRM heatsinks, M.2 SSD heatsinks, etc. SilverStone even showed us an example of a stack with 7 of these fans. The IceMyst series comes in four models based on radiator size—240 mm x 120 mm, 280 mm x 140 mm, 360 mm x 120 mm, and 420 mm x 140 mm. By default, these coolers don't include any of those stackable fans, they're meant to be purchased separately as part of IceMyst Upgrade Kits. SilverStone plans to launch the IceMyst AIO series, and its companion Upgrade Kits, in July 2023.
 
I have no idea if this idea will be popular.
