Rigol DG1022z replacement fan type
« on: April 21, 2020, 01:03:53 pm »
I know there's people doing it for their DS1054z and since I'm ordering a fan for mine I was wondering if I should also replace my DG1022z fan as well which is equally noisy.
Do these models have the same fan?
If yes I can order two of the same type and have some peace in the bench!

Even in google image search, I couldn't find any photos from inside this device.
That has something to say, because there is almost no other device without pictures.
(If you are lucky enough to see a type designation of the fan, you can determine the mass in the data sheet).

Any estimates or inaccurate hearsay bring you nothing.
Since you would have to open it for the conversion anyway, I would open the DG1022Z in your place now,
measure the fan myself and then know it exactly.

Fan is the same as Ds1054z.
I'v replaced it with a sunon ha50151v4-10000-a99 which seems to have very similar specs and it's very quiet.
(Rpm is 3200 in the sunon vs 3500 on the Delta though)
Only time will tell :-/O

A long time ago I put a 12cm fan in my Rigol DS1052E, and mounted it diagonally in the cabinet.
There is plenty of space to fit this bigger fan. It just needs some pieces of cardboard to prevent the air from circulating from the back to the front of the fan.

These bigger fans are also much quiter for the same airflow.
I probably put a resistor in series to lower sound eveven more, I may have put in an LM317 and a pot for easier adjustment.

I also may have tied the fan itself down with come pieces of string to decouple it from the metal housing.
Be careful with tape or other materials that deteriorate over time.
You can do a lot with cardboard and a few staples. It does not look nice, but nobody has to see it and it is really quick and effective.
