Is it up to you as the customer to make the system silent ?
When I buy something new instead of DIY I expect not to play with it around.
Positive example:
My Silgent HD scope, it cames with a silent system out of the box, no improvements at the cost of warranty are needed.

Except of the shipping costs, yes.
Currently I´ve heard nothing new from them after their answer, let´s hope everything goes well.

For sure not but there are example of noisy instruments for any brand, including your beloved Siglent  ;), i.e. the SDS1104X-E.

In the past I swapped FANs in many instruments, including a GW Instek the same day I opened the box, the noise was sooo weird.

In many cases the problem are vibration and it's enough to make use of rubber mounts, small FAN motors (<=60mm) do have very high torque ripple that usually resonate with metallic chassis.

Rigol HDO do have FAN PWM speed regulation but for some reason the scope push them at max regardless the actual internal temp, I studied the file system and everything is there but they messed with thermal system configuration.

The SW speed hack works but if you want the best possible result you have to mount rubber screw and 25mm deep fans as I did, but here we are in a quite subjective field.

I.e. a friend of mine that bought the 2 channel version on Amazon (850 euro shipped from DE depot exactly as mine bought from Rigolshop.eu) is more then happy with software speed hack.

Your Siglent scope cost more than 3 times mine  ;) , for sure with that kind of budget I would consider it in place of Rigol HDO4K and here I agree that Rigol have to make a better acoustic design with scopes on sale at certain price.

First step should be to drop 60mm fans in favor to 80mm or 120mm, the price to pay is instrument size, not a problem in my case.

Anyway, the noisiest  scope that I ever used is an old PC based Lecroy back in 2008, it seemed a vacuum cleaner and the exhaust air was sooo hot  :)

The rigol HDO4000 also and it got the same fans... ;)
And this is the point.
As the MSO5000 was launched, everyone wonders about how rigol could do that at this price.
8GSa/s, deep memory, 2-ch awg inbuild, etc etc.
The answer was simple, by using the cheapest materials around their new chipset.
Same on the HDO1000 - But also the same on the HDO4000...
The 3-times more expensive 4000 got the same quality like the 1000, same display, same fans, (nearly) same main pcb...
A bit pathetic.

More low cost options will be in the marketplace later this year.  ;)

Nice !

Siglent Armada is again active here, now we are going to enjoy with a fair review by Martin, who is notoriously impartial with Rigol and Siglent comparisons.

What a Joke.
