There few users here who have Vega FE inside eGPU, it should works without issue as far I know

Thanks @ikir. Next key question (and I've searched but can't find) if anyone has installed the watercooled version (or even a RX 64 water cooled) in the Akitio Node?

Can't speak for anyone else but with the Sonnet enclosure (one of the roomier models out there), there's no easy way to fit or configure a water-cooled GPU that size in the box. I recommend against it. Most of the boxes you see on this site weren't designed for it IMO. If you haven't purchased yet, play it safe and go with the air cooled version. For C4D the level of performance you will get between the two will not be too different IMO.

To be honest that would go for most OpenGL and OpenCL accelerated tasks and most apps. Also with C4D, R20 likely to be a bigger release than most as they start hooking the rewritten core into different functions, and much of that may actually be CPU-dependent, not GPU-dependent. MAXONs engineers tend to optimize very carefully towards whichever hardware is best suited to the computational task at hand, vs. other developers which tend to optimize across the board for one or the other. All that is another way of saying don't give yourself too big a headache trying to fit a square peg into a round hole (liquid cooled uber-GPU for that extra 4.8% performance), when you're better off going with a slightly less powerful card and more powerful rig overall.

Bring peace to your computing life: stop trying to understand Apple.

For strictly speaking about fit, I do not agree.

This pic is a bit old, but I was able to fit 1) Vega FE LC, 2) larger SFX-L PSU, and 3) extra 120mm pull fan at exhaust side of the radiator, with enough room for good air flow. The Sonnet BreakAway Box is indeed designed for exactly this.

I don’t have the 2) or 3) anymore, but reason to remove them had nothing to do with how they ‘fit’.

I won’t comment on if one needs the extra performance, or not. But getting the LC has other considerations. One is the noise. Among the people who was affected by higher fan speed, I was not all that bothered with noise. The LC, allowed me to manage the fan noise much better. Another consideration is heat. Take a look at how I solved both the heat and noise here.

The issues with Sonnet is Power. My 550 drives the Vega FE LC with stock PSU. But I wouldn’t be able to do that if I was using PD.

@jyin, thanks for the informative post. May I ask what is the 800W PSU you are using in the picture? I am waiting for my FE LC to arrive, I was planning to use my Corsair 650W, hoping that it will be ok.

That PSU was SilverStone SX800. I no longer have it, and I can't recommend it for eGPU.

Despite Tom's Hardware's in-depth review and good score in cross-loading and ripple. It utterly failed to power the GPU.

I am back on the stock OEM PSU now, and I have not had any issues yet.

Please note that I do NOT use the PD, so I have 87W head-room.

So in the name of science I got myself a Vega FE liquid, and with a small amount of non-damaging hackery I managed to squeeze it into the Akitio Node. The good news ends there. For the moment it's not detected by MacOS 10.3.2 or 10.3.3. I'm currently installing 10.13.4 public beta 1 and hope for more luck.

Boy the fan is loud...

Which fan? The radiator one?

I should do noise meter capture when it’s quiet at night and post it here. But last time I did that, the difference between eGPU off and on was like 2db at sitting distance for me.

@dangerous25 I'm not sure why the Vega FE eGPU wouldn't show up in 10.13.2 and 10.13.3. Is it connecting to your iMac Pro?

I recently did some testings with the max number of eGPUs a Mac can host. It seems one per Thunderbolt controller is the limit. Here's a plug-and-play dual Vega eGPUs in the late 2016 15" MacBook Pro. When plugging two eGPUs into both ports hosted by one Thunderbolt controller, one of the eGPUs simply not work (shows up as Display instead of full name). Daisy-chaining two eGPUs to use one port produces the same result.

Just got a FE liquid and it's not recognised by 10.13.4 b1 also.
When I connect the tb3 cable to MBP 2017 node and card switch on and fan go to max rpm.
Seems like liquid version is seen as different card than FE air
