Will this setup (mockup with aluminium tool holder) suck enough of the heat? Can I omit the heater-fan then? The idea is similar to this setup: http://forums.reprap.org/read.php?177,3 ... msg-322180 But the guy used a smaller mount. Nice idea nevertheless.
The issue here is that you need to get heat away from that heatbreak right down at the very bottom fin. If you're just heatsinking the top of the hotend heatsink then the bottom of the heatsink is going to be too hot for it to function properly.
Ok. The 3cm fan needs to be installed. Checked the fan after unpackagig yesterday at 9 Volts. Fan is not to loud at this speed (depending on voltage). Will install the fanduct-mod too. Adds a 4cm fan and cooling the area around the nozzle tip. Should this small fan be powered permanently at 12Volts?
Ok. This leads to the core of the question. Make it silent. The amount of airflow m3/minute should be known. Right? Is there a known alternative fan? Bigger with the same or better airflow operating nearly silently? I think of replacing: 1. this tiny fan plus 2. the additional fan for cooling the printed filament by one fan combined i.e. 4cm or bigger.
