> [@](#): > > nopick, is that fan 5v or 12v? Do you have a link to that fan? I’m not nopick but I’ll answer anyway 🙂 . The always on fan is 5V. The part used by LulzBot is (pick the 5V one): [https://www.lulzbot.com/store/parts/40mm-pelonis-low-flow-fan](https://www.lulzbot.com/store/parts/40mm-pelonis-low-flow-fan) From the manufacturer: [c4010l05bplb1-7](http://catalog.pelonistechnologies.com/item/dc-fans/c-series-standard-dc-fans/c4010l05bplb1-7) 3.87cfm Same size from the same manufacturer: [c4010m05bplb1-7](http://catalog.pelonistechnologies.com/item/dc-fans/c-series-standard-dc-fans/c4010m05bplb1-7) 4.82cfm Or the big guy (40x40x20): [c4020h05bplb1-7](http://catalog.pelonistechnologies.com/item/dc-fans/c-series-standard-dc-fans/c4020h05bplb1-7) 8.21cfm Personally, I like Noctua fans: [nf-a4x10-5v](https://noctua.at/en/products/fan/nf-a4x10-5v) (4.82cfm) or [nf-a4x20-5v](https://noctua.at/en/products/fan/nf-a4x20-5v) (5.53cfm) and they are available on Amazon: [40x40x10](https://www.amazon.com/Noctua-Cooling-Bearing-NF-A4X10-FLX-5V/dp/B00NEMGCIA) or [40x40x20](https://www.amazon.com/Noctua-NF-A4x20-5V-premium-quality-quiet/dp/B072Q3CMRW) While I was on Amazon I found this one, [https://www.amazon.com/4010-5V-Brushless-Cooling-Fan/dp/B071KSNNQ5](https://www.amazon.com/4010-5V-Brushless-Cooling-Fan/dp/B071KSNNQ5) 5.5cfm but I have no idea about its quality (but the price is right). --- _[View the full topic](https://forum.lulzbot.com/t/filament-feed-failure/5693)._
