Why this website?
I did this test for myself, but maybe the results are interessting for someone else too.That's why I've created this Website. I have tried to evaluate the products objectively and have carried out the tests to the best of my belief. I encourage you to form your own opinion.

Test system
Fractal Design Terra (Jade) Mini-ITX
AMD Ryzen 7 9800X3D
ASUS ROG Strix B650E-I Gaming WIFI
Corsair SF Series Platinum SF1000 1000W SFX
Corsair Vengeance DIMM Kit 64GB, DDR5-6000, CL30
Kingston KC3000 PCIe 4.0 NVMe SSD 4TB, M.2
ASUS ProArt GeForce RTX 4080 SUPER OC (2.5 slots)
No additional case fans (In order not to falsify the results)
For every cooler Noctua NT-H1 thermal paste
Sound level meter PCE-323 from PCE Instruments (50 cm distance)
Coolers
Only low-profile air coolers
Maximum height of 77mm
Suitable for AM5 socket without any additional bracket to buy (this disqualifies for example Thermalright AXP-200 series)
For testing of the contact frame I used always the same amount of thermal paste and a newton meter screwdriver, to have always the same pressure on the CPU

Additional Contact Frame Test
Settings used for 100% fan speed:
100% fan speed
ca. 75 W limit* (3 cores / 10 threads / cycle cores 2 minutes / 50% of TDP)
20 minutes test run
*Without power limit (stress test on all 8 cores) the CPU would be very quick at 95°C and do thermal throttling, because the power consumption goes up to 150 W !
The 9800X3D utilize 60-100 W in Gaming, from what I have seen in tests online. I think ~75 W is fair enough for a "real world" cpu cooler test.
Settings used for 40 dB noise limit:
Maximum noise level of 40 dB** - limited with fancontrol
ca. 56 W (2 cores / 10 threads / cycle cores 2 minutes)
20 minutes test run
**40 dB is a "good" noise level - at least for me :) but of course I can't use much more power (W) in the test, due to the noise level limit... otherwise the temperatures will go uuuuuuuuup.
Table & Details usage
I recommend to use a computer with a higher resolution :)
For detailed results and screenshots of the test runs, click on a cooler and look into the detailed results below the table.
My personal takeaways
It's a great processor, but hungry too ;)
When using the new 9800X3D CPU with a low profile air cooler, I would suggest to undervolt it (e.g. AMD Curve Optimizer). All tested low-profile coolers struggle when it goes over 95 W. For gaming it could be ok, not to undervolt it. But for computationally intensive tasks that require more power and over a longer period of time (e.g. rendering, ...) the low-profile coolers have a hard time, as the TDP for the processor is 150 W. The best way to determine whether a 9800X3D is suitable for you in an ITX system is to look at your planned activities with the system.
Additional you should consider the airflow through the case. I normally install 2x 120mm low-profile fans in a Terra. I recommend to use additonal case fans if possible.
I thought I will create something like a ranking with my favourites, but I removed it. I don't want to act as an influencer and based on the results.
I found my top cooler ;) and therefore my personal target is achieved. I hope the results are helpful for you too!
In addition to the temperature, please also keep an eye on the noise. I saw often that people sell their ITX system because it was too loud for them.
What upsets me is that the manufacturers' TDP specifications do not correspond to reality in the slightest. It shows that low-profile coolers struggle around 90-95 W. What Akasa, Jonsbo, ID-Cooling, Thermalright, DeepCool, etc. claim to be able to achieve... can confidently be described as pure marketing.
I got incomplete deliveries from Raijintek and Alpenföhn. Raijintek sends me from Taiwan the missing bracket (ETA February). Alpenföhn didn't respond on 3 messages and requests.
Do Akasa and ID-Cooling somehow belong together? It has to be? They sell the same cooler (just a different fan) and accessories?
What I don't really know.... what's about the max. dBA figures in the tech. specs? Not a single one is real? I think I need to do some research on it ;)
