Fan Security

Some "Fang" fans need to be secured on their visible side, just to avoid damaging the blades while the fan is rotating. Here is a small protective grid placed, in my case, on the 2 NOCTUA 40x40 fans that equip my heating head and the nozzle. I didn't add a nozzle around it because I consider that it could disturb the incoming air flow. The NOCTUA are efficient enough to do without this artifice.
