5800X3D direct die

[Kitsan]

I'm thinking about buying a 5800X3D to replace my 5900X as i'm getting a 4090 soon, all I use my PC for is gaming.

 

While I have both CPUs, I was thinking about direct die on the 5800X3D and I was wondering if I need to buy anything specifically to do it?

(I have done direct die before on Intel but not AM4)

 

I was going to use my current ASUS Ryujin 360 II but I do have all the parts except the CPU block for a 360+420 loop if need be since I don't think i'll be upgrading for a couple of years after this.

There's no reason to really do this. The X3d CPU's are arguably some of the worst AMD cpu's for overclocking, the IHS is soldered and deliding isn't worth doing given the risks. It's not like it's that difficult to cool either.

It'd be a terrible plan.  

 

X3D Chips are dramatically cooler than their X cousins.  Your 5800X3D will be waaay cooler than your 5900X is.  

 

Your existing 360mm is beyond overkill.

 

The 5800X3D is coming in at 25W (about 20%) lower than your CPU on stress tests:

Direct-die is never a great idea in the last few generations for daily use. It doesn't worry too much if I break the CPU as ill still have my 5900X, it's part of the risk in the process.

 

I want to do it for the sake of it (I enjoy this kind of thing) and also to have a quieter fan curve since the 4090 Strix will be dumping a lot of extra heat into the case.

 

So I'm more interested in what I have to do?

 

My understanding from the reading I've done is that the Z height of the 7000 die is lower than 5000 series, so it has a 1.7mm thicker IHS. Therefore I should be able to use the Thermal Grizzly frame https://www.thermal-grizzly.com/en/products/583-ryzen-7000-direct-die-frame-en to help protect the die, obviously, it won't do as good a job but it'll help with the lopsided nature of the 5800x3d die.

 

My main concern is that the ASUS Ryujin 360 II won't be able to go low enough to make proper contact with the die.

Delidding was very easy, literally only took 5 mins. 
 

Removing the solder residue and then I’ll see if my AIO will fit.

[Kitsan]

Solder was different to intel, I applied Liquid Metal twice and it was very slow to break it down. So I used a razor in the end.

 

There is no scoring to the surface, it’s the remaining solder.

 

I’m a bit too tired to put it in my system tonight, but hopefully will have an update tomorrow.

The balls you have bro...

was thinking of liquid cooling my 5800x3d lol, but i wouldn't recommend pairing it with a 4090 because it would bottleneck it by a bit.
