AMD v620 Shroud/Fans options

[cesarinpillin]

To resume: Bought a V620, looking for cooling solutions.
Details: I'm on Vancouver, BC, Canada.

As per my row of comments here: https://forums.servethehome.com/index.php?threads/amd-radeon-pro-v620-32gb-gddr6-gpus-565.47945

Been trying to find a proper fan/blower for it.
Most people seem to use the classic adapter+snail blower at the end of the card.
Others recommend a custom 3d printer shroud.


Problems: AliExpress V620 snail cooler blowers(which look almost identical to Mi50 ones) cost approximately 40% more than the MI50 ones and they want to slap shipping on top (the mi50's are free shipping).
No vendor knows if there is compatibility ( I assume they just print the 3d models someone else created for the Mi50 and call it a day after adding the blower).
Note that I lack of 3d printer and the local stores have not answered my quote requests.

So.. questions:

1. Are the rear (where the power connectors are) screws similar between the Mi50 and the V620? (from a visible standpoint they seem very similar but then I do not own a mi50).
2. Would it be better to use a custom full shroud than a snail blower?
3. My budget was kind of blown right now. So I want to keep costs low. Or should I just bite the bullet and buy the overpriced V620 versions thru AliExpress?

Most server gpu's have screws in same positions (amd and nv) thus all 3d printed snail blowers will work on all datacenter gpu's as they are shipped for server/workstation standard. *only differences in most nv cards you don't have the top screw - you only have 3 on the bottom. Size wise they are also the same.

The mentioned full shroud replacement will likely need the 3d model adjusted.
Most of those snail shrouds, and full shrouds do not include fan - keep that in mind. You will have to spend more.


Alternative option is to buy high pressure fan, and mount it outside in pull configuration like supermicro workstation do. (its also what i use for passive cards.)

2. What is better?
custom full shroud gives you more space in your case *depending obviously what solution you choose.
all solutions will most likely be loud.

Sorry what about the $20 ones on ebay? I don't know if they work well or not, but 20 seems reasonable.

My local library offers access to a 3d printer, any chance yours does? If you had a design already made, I could also print you one and snail mail it for the price of shipping (I have my own printer).

Im checking one of them, but so far all of them are 30+ USD + 20 or more on shipping.


So far I noticed 4 options:

1. Full shroud replacement for large fan.
2. Small shroud replacement with a blower fan. <-- only seen compatible with MI50
3. a blower fan at the end using an adapter (snail style)
4. and the idea Cyklon says.. a high pressure fan on the outside.

2 and 4 seem very loud. Im looking for #1 that is compatible with V620.. and #3 is very expensive for V620's.


Also thanks for the offer. If I run out of options I might take your offer.

Jesus, finally got a response from one of the local 3d printing companies.. They want an insane 100 CAD for a full shroud with no adjusts and 60 CAD for the snail fan style lol.

Hah that's insane, well actually genius because it's like $1 worth of material. I can't find any V620 fan shrouds to print, but I do see the Mi50 ones if you can use them? This one is sweet AMD Instinct MI50 shroud by Bit Matter | Download free STL model | Printables.com

Pretty sure the MI50 shroud is incompatible. The snail style rear fan might be. I mean the size is the same but the difference is the screws I believe.
I assume it might be usable if you use a wider hole on the horizontal space.

Anyway I did bit the bullet and I ended buying one from AliExpress supposedly for MI620.
Well see how it goes.

if holes are larger just use washers; if holes are too small just screw it through the plastic.
