Introduction
Thanks for cechking on this short guide how I solved and replaced the super noisy fan of the quite old DeckLink HD Extreme 3D+ Card from Blackmagic.
I wantet to find a solution without soldering, and here it is.
Took me about a week until I had everything together that I needed. Time for research not included.
I am sure one could to this much nicer. But I don’t look at it all the time so I don’t mind if there is a lot cable around or the fan does not sit perfectly aligned. So be sure to be as precise as you like and see this more as a inspiration.
You will need quite a few things:
- Replacement Fan which is silent of course!
- Maybe a small fan grill to add to the top.
- New screws (M2)
- 3Pin 1.5 ZH 1,5mm Mini Micro JST
- Isolation tape.
Fan
Technical data of my replacment fan:
Size 40 mm
Thickness 10 mm
Mounting hole spacing 32,5 mm
Rotational speed 4500 RPM+/- 10%
Airflow 8,26 m3/h
Noise 14,9 dB (A
Bearing FDB (Fluid Dynamic Bearing) Cable length 30 cm Connector 3Pin
Power 6,5~12V DC / 0,02A ~ 0,05A / 0,13W ~ 0,6W
Original fan:
COFAN F-4008L 12B
DC12V 0.10A
JST
The JST is the small white connector. On the board is a 3Pin 1.5 ZH 1,5mm Mini Micro JST. I bought some after i measured aproximatley and they did fit.
M2 screws
I went to a local shop to get the right size for the fan. But it is definatly a M2 because the fan is screwed to the cooler underneath. In my case I took 2cm screw length but 16mm would have been enough.
Just do an online search where to buy this stuff.
Have fun!

Remember the cable colors at the connector and which position they are!

My replacement JST came in a different color order.

I assumed the fan I bought would have the same colored connection as the original one. Result: positive.
-
So I did switch the black with the red color. But be sure to check which cable colors your JSTs come with and which order they have.
-
The connectors have to match with the board. Otherwise the fan is spinning the wrong direction.

i wonder how you'd put another card one next to this with new fan contraption protruding beyond limits :|
also, heatsink mounting hole distance is not stated so the whole guide is pretty much useless, except for original fan model being disclosed ;p
@ujczmbg9clcci9r true, the spot next to the card will be not available for other cards. unless you find a different replacement fan...
and for the distance: its not that tight/important, the screws go in the heatsink below which allows a little leeway.
