MS-01 nvme fan replacement

[Tlex]

I would like to replace the Broad Fan BF07506H05FP fan (5vdc/0.5A) with a bigger Noctua NF-A14 (5vdc/0.26A) in a 3d printed enclosure.
Does anyone knows the pinout for the Broad Fan ?

Its standard

red is positive
blue is pwm
black is ground
yellow is sense

but you will need to add a resistor to beat down half an Amp - else your noctua fan will likely fail sooner.

I don't think that's necessary. As long as it's 5V it will be fine.

 

[Tlex]

Yeah well the Noctua is indeed 5vdc. I tought as long as the replacement fan was draining less current it would be ok isn't it ?

 

[CyklonDX]

It depends - if ms-01 wants to pump 0.5A at full speed, then the fan bearing will burn down as it will be forced to run at almost 2x the rated speed.
If ms01 senses limits correctly then there's nothing to worry about.

I tought that was the case for voltage (overvoltage could fry things) but if more current is available to a device the device will take whatever it can leaving what is unneeded. ie: in you house you 15A breaker, if a device like a fan only takes 1A well it wont fry.

Any way, I did the swap and tried both at min and max power and that works A1 so far ! pretty quiet and cold.
I'll update with the link to the 3d case I made for it later here

 

[CyklonDX]

Amp is representing flow of electrons through the conductor. i.e. speed of current at which voltage is delivered.

That is correct. So in this case, the fan pipe size is 0.26A meaning that no more than 0.26A will go through. the same goes for the MS-01, it drains about 1.5A max on 120v even if plugged on a 15A circuit

 

[CyklonDX]

Since 0.5A connects to 0.26A the resistance will greater thus it will get hotter (and fail faster, or just blow/burn at some point if it gets too big), or it will result in higher wattage resulting in higher rpm; as Sinusoidal will get faster cycles. (faster failure)

but again sense should know limits.

nope, that's not how it works sorry.

Yeah its incorrect - apologies - brain spasm.
pwm header circuit runs +12V 2A, and fan motor circuit uses that specific configuration to calculate its pulse modulation to power fan motor circuit that only takes what it wants from whats available on the line.

Hey there!

I recently did it, but needed to completely brake original fan and that was really mind-blowing.

Guys from minisforum seems like exchanged 2 right pins from default ones comparing to common pinouts. Noctua using seems like default ones which you can find in Knowledge Base, but ms-01 has a bit different order of wires.

Please take a look on a picture and do your own connectivity.

G (black) - GND
V (red) - power +5
P (blue) - PWM signal
S (yellow) - Speed sensor

Btw, for connecting Noctua NF-A14 I needed to buy additional adapter.

Hope that will help you and save some time, cause I spent a lot

SUPER HELPFUL MAN. THANKS! I can confirm mine has the same wire configuration as well.

I just installed "Noctua NF-A14 5V PWM, Premium Quiet Fan with USB Power Adaptor Cable, 4-Pin, 5V Version (140mm, Brown)" available on Amazon and used the following adapted (self made):
MS01 : Noctua
Black Black

The correct connector for MS01 was found in "1.25mm Male and Female Connectors Socket and Plug with Pre-Crimped Cables Compatible with JST Molex PicoBlade 1.25 for Pixhawk Silicone 13cm Wire (Male and Female)" kit available on Amazon.

Let me know if you have any further questions, will be glad to help.

When you made the custom end (1.25 JST) how did you connect it to the 4 Pin PWM side? I am assuming you soldered them?
How long did you make the combined cable to keep it tidy inside the MS01?
Can you link to which of the 3D files you used?
Example there are the following files:
+ ms-01 fan housing v2.stl

+ ms-01 blackplate v2.stl

+ Filter plate v2.stl

+ Filterplate with fangrid.stl

+ Front plate v2.stl


Thank you!

Hello,
Yes I used a soldering iron and connected the wires using the color matching as mentioned in my previous post. The kit with connectors came with 13 cm wires + plus it was 2 cm extra from Noctua cable - I cut off the Noctua connector from another cable coming from a different Noctua fan. The fan had its own cable which was pretty long (17-20 cm) i.e. the cable length was not a problem in any case. I removed the NVME original fan and the plate it was attached to therefore I had enough room inside to carefully coil up the fan's cable.

Regarding 3D printing: I sent the link

to my neighbor and he printed the case and the plate for me - sorry, this is all what I know about it.

One more thing to mention - for people living in the USA who does not have the 1.25 connector/soldering iron etc -you might want to check (I did not use it)
4 Pin PicoBlade 1.25mm to 4 Pin Standard PC PWM Fan Adapter Cable

I mentioned the USA because I dont know how much it would be to ship the item to Canada, that is why I had to spend more get the kit with connectors.

The info about the adapter has been taken from

Hello,
is this pin-out working for you?

I founded different in few posts above yours:

G (black) - GND
V (red) - power +5
P (blue) - PWM signal
S (yellow) - Speed sensor

and according to Noctuas pin-out, yours is different:


Thank you.
