DeckLink HD Extreme 3D+ Fan Replacement

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!

    • WARNING: Be carefull here. I did choose to trial and error to find the solution. But you might break your PC or the board.

    • 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.

    • Check step 2: Remember the connection order. You might break something.

    • The connectors have to match with the board. Otherwise the fan is spinning the wrong direction.

    • Tighten the fan carefully.

    • Make sure it sits well and is tight! Otherwise you get movement noise.

    • I know, mine isn't perfectly aligned. But it does work for me.

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
