There are multiple big advantages to such a small upgrade.
- They keep the heatblock insulated, you don't want your heatblock and nozzle to cool down because of the part cooling fan, do you?
- Plastic won't stick to the heatblock anymore! This significantly lowers the chance of filament blobs and failed prints in general.
- The screw holes for the thermistor and heater screws are covered, no more plastic residue fills the bolt head, this makes it easier to unscrew the heater- and thermistor cartridge in case they break.
- Less heat radiates from the heatblock, this causes a cooler environment and better part cooling for the print.
