@nazarewk:matrix.orgkdnI'm not sure what kind of device(s) should I get11:20:05
@k900:0upti.meK900Most fans are perfectly fine with basically any level of PWM signal11:20:28
@k900:0upti.meK900A device for what? 11:20:38
@nazarewk:matrix.orgkdnto join those 8 together, power and adjust their speeds11:20:55
@nazarewk:matrix.orgkdnpreferably in 2 groups of 411:21:06
@k900:0upti.meK900Are they daisy chainable? 11:21:57
@k900:0upti.meK900Can you link the fan model, actually? 11:22:05
@nazarewk:matrix.orgkdnhttps://www.arctic.de/en/P14-PWM-PST-CO/ACFAN00126A11:22:12
@nazarewk:matrix.orgkdni see mostly 2.5A LED power supplies for PWM11:23:47
@k900:0upti.meK900Yeah those daisy chain 11:23:53
@k900:0upti.meK900And are 12V11:24:16
@k900:0upti.meK900So if you can get a 12V source, you can jank something together pretty easily 11:24:30
@k900:0upti.meK900You basically just run 12V to the power pins11:25:23
@k900:0upti.meK900And then a PWM signal from an RPi or whatever to the PWM pin 11:25:44
@k900:0upti.meK900 But also if any of your machines have a 4-pin fan header 11:26:02
@k900:0upti.meK900Which is very likely as those things are bog standard 11:26:09
@k900:0upti.meK900You should probably just use that 11:26:16
@nazarewk:matrix.orgkdnthey definitely do11:26:22
@nazarewk:matrix.orgkdnso plug directly into some mobos in 2 daisy chain groups instead of getting any extra equipment?11:26:58
@k900:0upti.meK900Yes 11:27:41
@k900:0upti.meK900Why have extra hardware 11:27:53
@k900:0upti.meK900If you can not have extra hardware 11:27:57

@motiejus:jakstys.ltmotiejusI recall you testing frigate with coral before; out of curiosity, why did you switch? Any problems with coral, or you found openvino to be integrated "well enough"?20:25:23
