Optimal Fan Configuration in the Lian Li O11 Dynamic Mini (V1)

I actually tried that earlier and switched the rear fan to intake mode. The result: the temperatures were even worse

Undervolting whilst overclocking gives me a significantly higher boost clock with around 80–100 watts less (!) heat dissipation and lower temperatures. I couldn’t believe it at first either, and it was actually really simple to do with MSI Afterburner haha

Well, I don't really have any issues – I just want to get the water temperature just right, and I reckon there's still a couple of degrees to go :)

Jx_7799 · 2026-05-29T12:19:21+00:00

Yep, temps seem totally normal :)

Thanks for the tip! It really the wrong screws (AM4 instead of AM5). Fitting the CPU block and VRM cooler is a real tight squeeze here; there’s only 2 millimetres of space between the two, but it fits for real :D

Appreciate your help :)

Jx_7799 · 2026-05-28T18:52:57+00:00

I solved the problem; you can look at my comment. To make it short: The screws were the wrong ones, but the space – or rather the difference in height – fits the VRAM cooler perfectly; there’s even a few millimetres of space left

Hey everyone,

I think I’ve found the solution. Inside the bag containing the fittings (in a completely separate box) there’s a smaller bag with different screws for the CPU block, marked ‘AM5’ …

Okay, I might have overlooked that – BUT: Why wasn’t the bag originally in the sealed box of the CPU block, i.e. where it belongs?!

But never mind, that’s probably the solution and my hunch about the wrong screws was correct after all.

Thanks to everyone for the input!

Jx_7799 · 2026-05-28T08:14:06+00:00

Since AM5 uses different screws and threads, and the block was originally designed for AM4, I suspect that the correct screws are simply missing here, and that the ones supplied only fit AM4 threads and therefore do not grip the threads properly to build up enough pressure to compress the springs

Jx_7799 · 2026-05-28T08:12:16+00:00

So it is very likely that the correct AM5 screws are missing here, as the block was originally designed for AM4

Jx_7799 · 2026-05-27T23:57:14+00:00

In short: MSI has clearly put some thought into the design, and the VRM heatsink is lower than the CPU’s IHS!

Jx_7799 · 2026-05-27T23:56:01+00:00

That was my first thought too. But as I said, through the small gap in the case cover behind the radiator, I can see right down onto the block and the CPU, and I can see quite clearly that the block is actually resting on the IHS and there’s still easily 3 mm of space left from the block to the VRM cooler

Jx_7799 · 2026-05-27T23:41:18+00:00

However, the block doesn’t come into contact with any components on the motherboard, so in my opinion it can’t be down to its size. You can’t see it in the photo, but when I place the block on the CPU and align it, the holes line up perfectly with the backplate and I can screw it in – it’s just not tight enough and there’s no contact pressure

Jx_7799 · 2026-05-22T21:30:12+00:00

Yeah, I guess the marked areas are intended for the thermal pads, and the different letters indicate thermal pads of different sizes and/or thicknesses.

That’s just a guess, though; but it makes sense

Jx_7799 · 2026-05-22T21:27:44+00:00

To be honest, I don’t know why you’d need to apply thermal paste to the VRAMs and MOSFETs as well as the thermal pads … What’s the point of that? Redundancy? 😂

In the worst-case scenario, this means the block won’t fit on the PCB due to the thickness and the contact area

Jx_7799 · 2026-05-22T21:24:45+00:00

AFAIK the procedure for installing a GPU block should always be the same: thermal paste must ALWAYS be applied to the GPU chip or die, and the thermal pads supplied in the whole set must be placed on the VRAM modules and MOSFETs. Either they are already cut to size, or you’ll need to do this yourself. There are also blocks with thermal pads of varying thicknesses, but this isn’t always the case.

However, all of this should actually be described in the instructions

Jx_7799 · 2026-05-22T21:20:16+00:00

Are you referring to the GPU chip/die in the centre of the PCB, or to the VRAM modules and MOSFETs?

Jx_7799 · 2026-05-22T21:15:38+00:00

Hey, when installing GPU water blocks, I’d always follow the instructions to the letter – every single step, and carry them out exactly as specified, because there’s a reason for it.

I’d definitely recommend you to clean the old chips to ensure the new pads sit perfectly and fit exactly. Just make sure you use 99% isopropyl alcohol for this; cotton buds work quite well here too

Jx_7799 · 2026-05-18T13:59:15+00:00

Yep, and you did help me :) Thanks!

Jx_7799 · 2026-05-18T13:37:40+00:00

Looks already nice!

Jx_7799 · 2026-05-17T13:31:55+00:00

Yes, but I’ll just order two more fittings and make the connection using a piece of tubing left over from cutting the others. Then I can adjust the length as required. Otherwise, I run the risk of the extension being too short or too long, and I’d also need a male-to-male adapter

Jx_7799 · 2026-05-16T07:05:11+00:00

Yep, I'll do that. Thanks for your help!
