Are you also tired of whiney and loud fans on low profile graphics cards? I've come up with a solution to keep the GPU both cool and quiet called deshrouding. In short, it means replacing the fans with both larger and thicker ones, whilst retaining the heatsink. These larger fans can spin a lot slower, making the GPU inaudible under load. A very welcome addition to a case you'll be putting in your living room or on your desk!
Yocto provides mounting points for two 60mm fans under the GPU. Depending on the radiator size of your GPU, you can attach fans up to 25mm thick to these points.
The sum of the fan thickness and the radiator height, starting from the PCB, can be no more than 48mm. As a reference, I've made a table below with all the radiator dimensions of most of the popular low profile GPU's.
There aren't many quality 60mm fans but we're lucky that Noctua, one of the best fan manufacturers, has a great one. The NF-A6x25 PWM is probably the best fan you can get when deshrouding your GPU.
Controlling fan speed
GPU's tend to use different fan headers than regular case fans use. To control the fan speed based on the GPU temperature, you can buy an adapter. However, many cards define a high minimum fan speed on their header so it is much easier and advised to use a fan header on your motherboard. You can then control the speed very precisely using software like Fan Control.
Note on the RTX A2000
The RTX A2000 is the strongest and most recent low profile GPU and a popular choice for the Yocto. But the blower style cooler makes it unsuitable for deshrouding. While it is a pretty quiet card, its minimum fan RPM can be annoying so I came up with a custom heatsink solution that enables you to deshroud this card!

How quiet does it get?
As for the results, they are spectacular. I have ran a test with 3 cards total: The MSI GTX 1050ti, MSI GTX 1650 and the RTX A2000 using my custom copper heatsink.
I use two Noctua NF-A6x25 PWM fans rotating at a speed of 1000 RPM at idle and 1800 RPM under full load, both inaudible speeds. The MSI cards didn't higher than 75C while the RTX A2000 didn't even go higher than 70C.
As you can see, deshrouding is a big improvement over idle speeds of 3000 RPM that the original coolers tend to have!
