AS3304T noise level? Louder than AS1104T/AS5304T?

Post by VojtVop »

According to reviews the AS3304T is much more louder at low fan speed than AS1104 and AS5304T. TechPowerUp suggests that the difference between AS3304T and AS1104T could be given by older OS version of AS3304T as it was released and reviewed much earlier while both uses same platform and same fan. And although AS5304T is the oldest of them it's based on different HW platform and was reviewed with ADM 3.5 while the others uses ADM 4.0 from the beginning. My question is if this suggestion is true, if AS3304T with newer OS version is as quiet as AS1104T/AS5304T or is it really as noisy as is measured in the reviews and AS1104T/AS5304T better fulfill request for silence. Thank you very much

My NAS is AS6604T. I can see FAN speed being around 520rpm when I set to low speed and NAS is almost idle (no matter ADM 4.0 or ADM 3.5). I do not hear any differences about noise. You can check FAN rpm to make sure of it on your model.
Actually I think the major noise is coming from HDD, rather FAN. I create volume 1 using SSD, volume 2 using normal HDDs. This way should put volume-2 HDDs into spin-down mode (motor off) when NAS is idle. FYI.

The AS6604T has been also measured by TechPowerUp with values just between AS1104T and AS5304T:

I have received this reply to my question (with a little bit changed formulation: "My question is if this suggestion is true and AS3304T with newer ADM version is as quiet as other mentioned models (at low fan speed) or if higher noise produced by the fan is permanent feature of AS3304T and buying AS1104T/AS5304T will better fulfill a request for silence?") from Asustor support:
All three mentioned models (AS1104T, AS3304T, AS5304T) are equipped with a 120mm system fan, generating the same amount of noise which is 19.7dB with idle HDD. Besides that, all three mentioned NASes can be updated to the newest OS version (ADM 4.0). That means, the higher level of noise generated by AS3304T fan is not a permanent feature, as long as the fan speed is set at the same level as it has place in two other models.
So this problem seems to be solved (hopefully).
