Alphacool Block Asus 5090 Astral IO Bracket by Astral LC

[Slash]

i ordered the Alphacool Block for the Asus 5090 Astral for my Astral 5090 LC (the one with the AIO)

Now i already disassembled my GPU to take a look on the PCB and everything.

The PCB is exactly the same like the "air Cooled" Astral. So the Waterblock should fit without any problems...

but...

i did take a look on the Manual of the Water block, and then i saw that the Air Cooled Astral, and the LC (AIO Cooled) Astral does not use the same "IO Bracket"!

on the Manual is point:

where i should put the parts J, K and L...
but the IO Bracket on the Astral LC does not have that folded lips (red marked on the picture)!



Is this a problem? if i dont use this screws?
I think the Block will still fit perfectly fine, but without these "folded" lips there will be a litle less Support for the PCB, and the whole wheigt will be on the Connections.

but I think that it should not be a problem if I otherwise support the graphics card well enough?

what is your opinion on this?

I don't see a problem there. Then the cover will just be held by the screws at the monitor ports.

Hi Eddy thanks for your reply.. and your opinion.

I was thinking the same.

I just was a bit unsure about it.

Then ill try it if the block arrives.

Ill make sure that i will support the GPU with a support bracket as much as possible.

To take the force away from the io bracket. Then it should be safe enough

can hardly wait for the block to arrive

wait what, how is this OK. all weight on the monitor ports and the pcie slot? no direct connection with the board and IO bracket? Isnt monitor ports held on with just solder? Will Alphacool pay for damaged pcb if it brakes? Why does Alphacool not include a custom black IO panel like EK does or at least have them able to be bought separately.

but why does it not have the bent parts? in this PCB pic it does from https://en.overclocking.com/review-rog-astral-lc-rtx-5090/2/
Did they use the air version for the PCB pic maybe? but they do say that its the LC in the title for the pic tho, guess they didnt vet the pic fully: We haven’t disassembled our copy, as it will be leaving for other colleagues

I have pics of mine... and there are definitly not the bent parts!

On the rtx 4090 strix they were all like that, just held on the ports! And ot was never a problem!

Here... manual of 4090 strix! Only screwed on the ports! No screws on the pcb... and it worked.


So i think its ok.

i see, well if there was no PCB damage from the 4090's guess that it's at least some proof of it not being destructive.

can someone explain the reasoning for not covering the middle of the gpu core on backside with thermal pads?
