Blower fans for a duet wifi

Hi I'm wondering is there a blower fan in the current market that can be successfully pwm controlled like I've bought a sunon blower and it is really hard to control the speed its ither all on or basically no airflow I mainly print petg and nylon and I only need like fan on at 25 to 30 percent power if that I'm debating going with just a 40x20 4 wire noctua fan for part cooling also I just bought a second 5015 blower different company same deal I like the idea of blower fans but I cant find one that is good with only being powered at 30 percent speed

What Sunon blower did you get? I have 2 different sunon models that work well. Though one of them is pretty weak and is only really useful at 100% anyway for PLA.

You can try adjusting the PWM frequency for the blower. It may give you more control range.

currently i used this https://www.aliexpress.com/item/32985338508.html and can run at 25% for my petg prints

That's not a sunon it's a fystec and mine doesn't have 3 wires but I have another one that I'm gonna try that has 3 wires so thanks tho

@Phaedrux I'll have to try that one that u put the link up for does it have 3 or 4 wires those usually work better for pwm I've found I've tried frequency as low as 100 Hertz up to 10000 Hertz with no luck

My sunon blower is only 2 wires and its ither on 100 percent power or it barely blows at all no middle ground

bigwood247

Is there any blower fans that are pwm capable they usually have 4 wires?

Yes, it even works at 10% PWM. The listing I purchased from was https://www.amazon.co.uk/gp/product/B07RSV5LTH/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1. They have a 24V version too.

@dc42 thanks I'll try those

The one I linked controls well down to 10%, though it doesn't move a lot of air through the duct at that point. Useful low range is probably 20% and at 100% it's very powerful.
