Although this applies to SG350X, it is very well possible it applies to your switch as well: https://forums.servethehome.com/ind...-xeon-d-10g-base-t-to-sfp-switch.16319/page-2, at the top
Thanks for the link to your old post - seems I got the wrong fan. Will look into something with a wider operating voltage range. Maybe a Sunon HA40201v4-0000c-c99.Although this applies to SG350X, it is very well possible it applies to your switch as well: https://forums.servethehome.com/ind...-xeon-d-10g-base-t-to-sfp-switch.16319/page-2, at the top
Is that the SG250(-26HP)? Does the adapter kit supplied with the PWM version allow you to connect directly to the fan headers or did you need to re-pin?I have that switch and this post about the suntron fans is WRONG. I had to buy a Noctua NF-A4x20 PWM fan from amazon. I unhooked the other two fans in that platform and it runs just fine.
I had to slice off the keyed interface on the plug, so i decided to just use the plug from the existing fan... I believe that I just unplugged all 3 ports and plugged in the new fan to those 3 pins. Mine is th SG350XG-24F it's a 24-Port 10G SFP+ that I found in the trash at work.Is that the SG250(-26HP)?

Did you check whether the cables are in the correct order in the 3-pin plug?sunon fan works with random error
Noctua NF A4x20 PWM starts a few seconds and stop ??? with error too
Hey, I also have the SG350x-48P and want to replace the fan too. Is there a solution now?Hi @psannz
thanks for your answer.
Yes I replaced PIN in correct order.
But it is not tacho but PWM signal in the middle. I tested VDC-PWM-ground and VDC-tacho-ground because I tested noctua PWM with 4 wires given by @iotapi322
but it starts and stops after some seconds...
Source: http://ww1.microchip.com/downloads/en/DeviceDoc/20001734C.pdfIn normal fan operation, pulse trains are present at SENSE1 (Pin 8) and SENSE2 (Pin 7). The TC654/ TC655 use these pulses to calculate the fan revolutions per minute (RPM). The fan RPM data is used to detect a worn out, stalled, open or unconnected fan. An RPM level below the user-programmable threshold causes the TC654/TC655 to assert a logic low alert signal (FAULT). The default threshold value is 500 RPM. Also, if this condition occurs, F1F (bit 0<0>) or F2F (bit 1<0>) in the Status Register will also be set to a ‘1’.
And I assume that Notcua is not able to work with 6V properly.Often overlooked in fan speed control is the actual start-up control period. When starting a fan from a nonoperating condition (fan speed is zero RPM), the desired PWM duty cycle or average fan voltage can not be applied immediately. Since the fan is at a rest position, the fan’s inertia must be overcome to get it started. The best way to accomplish this is to apply the full rated voltage to the fan for one second. This will ensure that in all operating environments, the fan will start and operate properly
Thank you a lot.here are more images of the final installation:

The only bad thing is the fan alert - but I can live with that.
