Graphics card fan for the AMD Radeon Pro W6800

You can also read this article in German here!

The AMD Radeon Pro W6800 is a professional graphics card that is mainly used to do architecture rendering, for example.

Of course, there are other areas of application where this graphics card can be used, but due to the size of the video memory of 32 GB, the AMD Radeon Pro W6800 is perfect for rendering larger projects.

In addition, this memory is a high-performance GDDR6 memory with ECC-Support!

In addition to the large video memory, you also have the option of using up to six monitors at the same time via the mini DisplayPort connections.

The reason why you decided to use these connections becomes clear relatively quickly when you take a closer look at the structure of the graphics card.

In contrast to normal consumer cards, with the AMD Radeon Pro W6800 and AMD Radeon Pro W6600, the cold air is sucked in via a radial fan and the heated air is then transported out of the PC case to the rear.

This principle is also called the DHE principle (Direct Heat Exhaust) and is mainly used in professional graphics cards.

This type of cooling is also ideal when it comes to installation in small workstations.

However, the AMD Radeon Pro W6800 also had a small problem with temperatures!

Because the rear backplate heats up a lot, especially under heavy loads, so that temperatures of approx. 80-90 ° C can be reached in the area of the graphics processor.

In the normal case, this does not affect this in the card, since it was designed for such temperatures, but I myself think that you could have built in an additional fan, as is the case, for example, with the Nvidia GeForce RTX 3080 Ti (Founders Edition) has been implemented.

With this principle, similar to the AMD Radeon Pro W6800, the cold air is sucked in from the side in order to cool the competent, but the warm air is not transported directly out of the computer case.

This approach to cooling is definitely very effective and you only have to ensure that the heated air can be discharged directly to the outside with this variant too.

For this reason I decided to come up with a solution for this problem myself!

I have already created a first prototype using Autodesk Fusion 360 and have also performed some simulations in order to be able to better control the heat development.

The primary goal of this project is primarily to reduce the temperatures in the area of the graphics processor, but also to lower the volume!

Because the problem here is that the radial fan turns up relatively quickly at full load in order to be able to guarantee the cooling of the individual competent persons.

This works quite well so far, but as soon as it gets too warm for the AMD Radeon Pro W6800, it starts to throttle the clock down independently so that the temperatures can be lowered.

So that this scenario can be rented out better in the future, I attach another housing to the backplate of the graphics card so that it can be cooled from two sides.

Of course, my prototype still looks very primitive at the moment, but that too will change over time.

First of all, it is important for me that the cooling performance and the noise development are improved!

Well, otherwise before I forget to tell you!

I paid for the AMD Radeon Pro W6800 myself out of pocket and would also like to point out that I did not receive any money or other services for the graphics cards or products mentioned in this article.

That was important to me to mention again at this point and in conclusion I would like to give you one last hint.

I will publish more information about this project here and on my YouTube-Channel in the future.
