Copper heatsinks

[Reciever]

Before you worry about liquid metal, need to have a process in place that can deliver a high probability of even pressure across the cores.

To use the second heatsink I would use 6 heatpipes, or for simplicity 4.

Thanks for the the thoughts, I agree, main reason I ask (this and for any other imput) is simply because of how much time it take to organise all the different processes.

As for even pressure that will depend on the accuracy/precision to which I can make the heatsink espesially the flatness of die area and spring geometry.

I would like to use 6 pipes for the dual heatsink versions but there is only so much room between the retention screws. I am also pretty sure the fins on current heatsinks are the biggest limiting factor not the heatpipes, the reason why I'm upgrading the gpu to copper fins... x3 6mm heatpipes flattened to 3.5mm should have at least 150w capacity provided they are not restricted by the condensor.

You stack the heatpipes.

This is the amount of room I have to work with.

I see, tight fit! Sorry if I came off direct, I take a large dose of sleep aids and it becomes difficult to articulate.

Should be able to go with 4 pipes then. It's been done on the ranger but it's worth noting that you will need to shave off some of the tensioner. The amount on the ranger was iirc a about a millimeter off each side.

Not saying it's verbatim the same, I very much doubt it would be but it could be an avenue to look at critically to see if it could work here.

All good, I guessed you didnt have the m18x so hard to tell what will work, I'm all for being critical for the sake of getting the best heatsink.

For the cpu I was going to make a whole new tensioner to give me room to run the heat pipes sideways to the 2nd gpu heatsink.

[Azther]

will your cpu design allow for the nvme adapter some people have? or will the extra pipes get in the way. asking since i do intend on getting one of those adapters at some point so would be nice to have both that and your heatsink

[kenny27]

In the process of getting one so I can make sure it does work and to have some of that nvme goodness for myself! 

Judging by the photos I've seen the heatpipes will go over no problems 👍

[Azther]

ah excellent, good to know 🙂

[ssj92]

I'm sure @kenny27 also wants this too but just to make sure, I wouldn't want to modify the chassis in any way to get new heatsinks to fit. 

 

One that fits right in without any mods to chassis would be my preferred one. Since you are getting the nvme raptor card it will be interesting to see if we can extend cpu heatsink and also cover raptor card or keep everything separate and get a heatsink to cover the raptor card itself 

[kenny27]

@ssj92Yes no chassis mods is the plan!

Thats a good idea... my concern would be the cpu heating m.2 drive unnecessarily if running a heatspreader directly to the heatpipes of the cpu... some testing required.

How hot is yours running at the moment?

Is there any room under the keyboard for a heatpipe to fit on the m.2 drive?

Not currently, but if are willing to help me out, I can have them in about a week. I've been working with a buddy to make models to 3D print and ensure they are the right sizes, we're still working on refining the models right now.

Can bend the heatpipes with an internal bend radius of 2x pipe diameter and flatten to 2mm so long as I preheat them... when you have figured your lengths I'll add them to my orders

I am working on making some all copper heatsinks for the R2, if anyone is interested please let me know. 

Just looking for some input on Primary GPU heatsink variations / achieving compatibility with as many GPUs as possible. There are 3 variations that I can think of:

1. Standard Dell AMD heatsink

2. 1070 heatsink with fins cut out of the heatsink

3. an RTX 5000 and RTX A4500 heatsink with an offset core. 

For the standard layout you can see in the Image attached I am planning to make areas 1 2 3 and 5 as close to the dell heatsink as possible both in coverage and heights. 

Is there any value in making area 4 the same level as area, are there any cards used in the m18x that could use this? And are there any other ideas/modifications I should be including or having a variation for?

 

Very interested in this project, Always that the RTX 4500 does not have an exaggerated price.

Maybe make a purchase with multiple cards to get a better price?

What heatsink combination would you be interested in, standard heatsinks or dual gpu or cpu heatsink?

Compatible with RTX A4500, in the Sloot that remains empty I would like to put Adapter MXM / NVME.

So I don't know if you can put a. Cooling over NVME Adapter.

It would be the best to have only Heat Sink for Master's GPU, CPU and NVME Adapter, connect 3 Heat Sink with Heat Pipes.

[rocas]

Something like that. 

Only my doubt in this project and the heat over MXM connectors.

Maybe he has less material above the connectors.

 

[kenny27]

@rocasThere should be enough room to run at least 2 heatpipes next to the nvme drive. Will need to get some temps of the nvme drives and some testing to see if there is any benefit cooling it on the cpu or gpu heatpipes, I have had my 3920xm over 90C when overclocking it and I dont really want the nvme driver to act as a cooler for my cpu!!

I'm not really worried about the mxm connectors, there is at least 4mm clearance so nothing should touch them.

It wont be quiet to the level of the water cooled M18x, I for sure dont have that capability at the moment. And I'm not to keen on having all 3 in 1 peice for the difficulty of making and also practicality of working just the cpu or gpu. 

[Azther]

I for one prefer that the components have their own separate heatsinks, that way the gpu or cpu wouldnt get heat soaked by the other component. As for the nvme situation, im sure a nvme heatsink by itself should provide adequate cooling would it not? seems kinda pointless to have the cpu extended over it for reasons you just mentioned, especially for XM cpu users.

@kenny27I apologize for being about a week late! Getting the measurements and actually creating the model in Solidworks has been quite hard, and I don't have too much time everyday to work on it. I should be printing and test fitting my first model pipe today or tomorrow. It probably won't entirely fit, but now that I have a reference model, adjusting it should be easier and take less time. Just for reference, this pipe is going to be quite long, without any bends it is about 440mm long, but I would expect that to change just a little bit as my measurements might not have been the most accurate. My main question is are you able to order and bend a pipe that long?

[Eban]

@Tenoroon

Sorry I just found this in some of my files.

I cant remember who posted this on the old NBR when I asked about liquid cooled AW 17.

This is a pic of AW18 prototype that was apparently made but never produced. Maybe it will give you ideas? (If you havent seen it before that is)

Oh I don't need anything for my Alienware, I'm trying to cool the MOSFET's on my 1070 in my P870DM, and I need a super long heatpipe to get the pipe from the FET's to the heatsink. Below is a rough image of what it would look like:

I'll try to avoid talking in this thread as I know its mostly about heatsinks for Alienware products, and I don't want to confuse any of you.

I seen this before but thanks for putting it up, haha I've thought about it, and may try it one day, for now I got my hands full with standard heat pipes and getting the skills/design for this kind of thing!

All good I know what its like, I'm still figuring the exact lengths I need. Time is always a stuggle, pretty sure I have done most my work on this project at 1am with a newborn in one arm, pencil, ruler and coffee in the other 😂

 

A long heatpipe should be no issue, hardest thing is ordering an exact length and determining what the length will be once bent, I'm not 100% on the gain I'll get having never bend these pipes before.

Are you ok with being 10mm or so  short? Too long is an issue atleast in the m18x... there is no extra room to play with.

 

Can you sneak the heatpipe over the card rather than going all the way round? Like this?

Yeah, the longer the heatpipe is the harder it seems to be able to get 100% accurate measurements hahaha.

If the length is a bit off, it should be fine, I'll find a way to fit it 🙂

I thought of doing it the way you have shown, but I plan on adding more heatpipes (which I may or many not need some help with, but that's for later down the road,) on top of the current heatpipes on the core, and if I do that, the VRM pipe would have to be bent upwards quite a bit in a very short distance, which may not be the best for the pipe. It may also stop me from using the bottom panel of the laptop if the pipes are stacked and too tall.

I got my first one printed, I'm expecting it not to fit my laptop, but I will use it as reference when I make changes to the model in Solidworks. I'll test fit it once I get home in a few hours.

EDIT: It seems I either really messes up my measurements or I did something wrong in Solidworks, the model pipe is WAY to big. I always kind of forget how much smaller the insides of my laptops look because they look gigantic in the pictures lol. I'll make another model tomorrow.

OK today I got in the mail for my ANTIQUATED, OBSOLETE, OUTDATED, FORMER DTR m18xr2 a cheap, unwanted triple pipe primary GPU heat sink for $8.09 plus tax and free shipping that nobody wants anymore!!! Just Saying

 

And they labeled it wrong to top it off!!!
