I recently received and then decided to return a Saturn Pro II via Amazon.  I’ll just share the review I wrote up for Amazon to explain:

————————
I bought this eGPU model on the promise of quiet running: a supposedly low noise case fan and a power supply unit (PSU) fan that only runs when needed.  However, I was disappointed to immediately discover that the case fan, which is always running while you're using your computer (I have a 2019 16" MacBook Pro), isn't so quiet.

I happened to have an ultra quiet, Noctua 120mm PWM 4-pin fan that is perfectly compatible so I thought, problem solved, right?!  The replacement fan I installed definitely runs quieter than the stock fan, though maybe not as quiet as a "Be Quiet Silent Wings 3" I put in my Razer Core X eGPU.  However, I then discovered that even though the PSU fan can and does turn itself on and off, it actually still runs every couple of minutes or so even while my MacBook Pro is essentially idle in macOS.

While the PSU fan is not very loud, it has an irritating sound quality to it.  After putting up with it for several hours, I decided it was too annoying to tolerate.  It's a shame too because it would have been nice to have the extra USB ports – but I ordered this model specifically for the promised low noise.

The Saturn Pro II may well be quieter than other eGPU's, however I know that it's possible to set up an eGPU that runs truly quiet until you start cranking on some heavy work.  This is because I've already gone through the experience of modifying a Razer Core X.  I followed some recommendations on the web to replace both the PSU and the case fan to make it run silent most of the time and it works!  I'll detail this on my separate review for that product.  (This Mantiz Saturn Pro II was going to be an upgrade and I was going to use the Razer Core X for another computer/location.)  I could probably replace the power supply unit in the Saturn Pro II to get a quiet fan but I'd have to go through the trouble to figure out which unit fits the case and I already know what will work with the Razer Core X.

The question is, why doesn't Mantiz or Razer (or some other manufacturer) make the extra effort to select these same fans and PSU's to produce a truly quiet external GPU case?  Anyway, I guess I'll be ordering another Razer Core X (plus the replacement PSU and case fan) and do the customization again.

And for anyone who's interested, yes, I was also able to get the Saturn Pro II to work under Windows and Boot Camp on my 2019 16" MacBook Pro.

————————

I’ll add here that the very quiet PSU I’m using in the Razer Core X now is the Corsair SF600 SFX version.  It works great, fan only comes on when needed and isn’t loud or annoying.  It did cost half as much as the Razer Core X though, but worth it to me for the normally quiet, MacBook-like running.

Would’ve been nice to have the USB ports on the Saturn Pro but from this thread it sounds like people are having trouble with those ports.  Interesting since people also have trouble with the ports on the Razer Core X Chroma, which I avoided for that reason.

@egpuch what I do know is my warranty replacement PSU shipped from Taiwan is now on customs, and DHL is now accusing me of being an "importer" and of "undervaluing the item in the package" for which I will be liable of a fine for false statement (!). I have just contacted Mantiz support regarding this, awaiting a reply. Before all this, Mantiz requested I send the noisy PSU before I got the new one, to Taiwan no less (not the location of the item I purchased) through a DHL label and export slip provided by them (but that I had to print and sign) with a value of 20USD for the outgoing unit. Apparently this return package has already reached Taiwan after I sent it last Wednesday the 2nd.

Nevertheless, current state of things is:

  • I have no PSU, and my eGPU is unusable, because Mantiz insisted I send the old unit at the same time (as if I was gonna keep the other for myself with that horrible noise...)
  • I am currently being accused by my own country's customs and/or DHL of undervaluing an import item due to the incoming PSU, which I never did
  • DHL wants me to sign a power-of-attorney document so they can accept the fine on my behalf and expedite customs, and probably charge me for the service as well as charging the fine on my name
  • I purchased an item originally on Germany, located in Germany, paying German tax for EU delivery and expecting no custom issues...

In no part of Mantiz support emails was I told anything like this would happen. I was hopeful when I got a slip to send my PSU to Taiwan that at least they would be using a DDP service for the incoming PSU. They apparently did but it's being held by customs anyway!

I was contacted by DHL last Thursday by phone (about the incoming package to my address), by a very nosy rep who kept doubting my statement that I was not supposed to know the value of a replacement part (I didn't pay for it!), but that the 20USD marked as value in the package slip seemed like a plausible value for an OEM like Mantiz to get that particular part in Taiwan. Yet I never said I imported any item...

I am disgruntled by this, although in a way, I know this isn't 100% Mantiz's fault. I have no doubt DHL is making the process difficult so they can get a customs handling commission (which I've heard it's one of their big sources of income...), or that the holidays may be impacting customs zealousness. But that doesn't change the fact I never imported anything and am now without the ability to use my 380USD piece of kit...

@Mymantiz_John would you please see what's going on?

DHL was the problem: they hadn't even checked the package to which they claimed I paid false statement, and arrived today and cleared customs fine. It seems DHL will outright lie so that they can get a customs clearing fee.

@mymantiz_john on page 19 of this thread you have provided us with the pmw curves for the Manitz Saturn Pro.

Thank very much you for that!

 

I have two further questions about this topic:

1. Which temperature is the graph referring to? Where is the sensor located?

2. You have also mentioned the temperature of the power-management-IC. Where is the location of this IC?

The case fan is not really providing any proper air flow to the main board because of the metal bracket and the PSU covering it.

Is this an issue and would adding a small heatsink to this IC solve the issue?

 

Thanks in advance!

 

Tim

@mymantiz_john Any chance to send next EU shippings before the end of the month? If not which would be more and less the date to arrive in Spain.

On the other hand, I'm planning to change the PSU with a Corsair RM650i because it is modular and really silent, so cable managing is easier, also improving air movement inside the case and generating much less noise. Do you know which would be the max wattage consume (aproximatedly) without the GPU connected? Knowing that I would know which GPU can be installed using less powerful PSU (650W), I'm going to connect ir to a 16" MBP so at least 100W are going to charge te MAC.

It is great that you are involved in this forum giving us support and replying our questions.

Thank you guys!

The Power consumption is : PD 100W + 41 W for Ports & Sata . Board Level: 12W 

By the way, we had modified the PSU fan with new ball bearing. That is silent! You actually don't need to change the PSU. The FSP 750W Gold we use is certified by Intel with Thunderbolt eGPU certification, I really don't suggest to change it.

@mymantiz_john, I have received the PSU with the replaced fan and it's definitely not "silent" as you suggest. The high pitch noise is gone and that's great, but when the fan starts spinning you can definitely hear it under idle load and I'm sitting 70cm across from it and my room is not very silent. I think it's either a matter of a cheap fan being utilised for the PSU or fan curve tweaking, because if we compare it with a Noctua A12x25 which I replaced for the main fan, this you can barely hear when it starts spinning under the same load.

I do wish there's a zero DB PSU in the world. To low down the FAN speed is a piece of cake but product life cycle & inner case is another thought. 

PPL likes to use laptop standard ( perhaps already get used to of the " silence " brought by it ). Please always remember the enclosure is a 700W up power consumption beast when it needs to be. There will be 5 fans ( GPU * 3, System Fan * 1 , PSU * 1 ) running at the same time when it is required to be heavy usage. We can easily adjust fan speed to be less then 1000 rPM at any time but MTBF could be reduced 2 years. I don't think it is going to be a honor or a right attitude to consumers.

Great to know, I’ll try it before any modifications.

I guess that no early shippings in Europe Excitement  , its going to be a long January...

Thank you again for the PSU info.

I bought the Mantiz V2 via Germany back in November and it was supposed to arrive in the UK in December. Unfortunately it shipped just as DHL suspended international deliveries to the UK. The package was returned, and now the whole customs situation has to be figured out post Brexit. Mantiz support had said on Saturday they would check on Monday if they will either resend or refund, but I'm still waiting to hear back. Really hoping it can be resent but I'm in the dark as to what's happening at the moment 😟

When did the PSU fan modification enter production? I received my unit beginning of December and would like to know if it already has it. Mantiz support did not reply...
