SAMA IM01 is the solution for you. Cooler Master nr200 has a case size adjusted, making it fit better. It’s a bit larger than the Lian Li, but considering modern GPUs and powerful cooling solutions, that’s a positive change. A slightly bigger model like the ASUS Prime 201 would be ideal.
A chipset doesnt mean a board is good. It has non functional rgb control (settingd arent rememberd usually) Poor vrms compared to well basically any other b650 Pwm headers have issues driving more than 1 fan or a pump Ram slots are on a lot of units differenr heights and crooked meaning that getting ram in is not easy. Heatsink shroud gets in the way of a lot of coolers (not part of the actual heatsink) And a bunch of they cheaped out here badly kinda dealios on that board. Basically a 120$ a620 board that got a b650 chipset and was priced at 350$ because of the other 3 itx boards 1 is also a gigabyte
You're asking if the issue comes from a splitter or if it's related to having too many headers.
A solid choice is the ASUS ROG Strix AX AM5 Micro ATX. It offers great performance and compatibility. Other options include MSI MEG AM5 and Gigabyte B550.
Your cooler is quite large, but there are affordable air coolers from thermalright that can easily accommodate your CPU. Adding four Arctic P12 fans with intake on both sides will improve airflow. A 5-pack offers better value and fits right away in a prime 201 setup.
Daughterboards featuring flaky connections were a pain—especially with the B650i Aorus Ultra. I even had to return the motherboard for the first time since the X79 era. The front I/O daughterboard’s connections tend to drop out when shaken, which isn’t reassuring. It relies on fan header adapters to access full 4-pin headers, and the M.2 slot with the CPU and PCIe connector feels poorly constructed—both in fit and mounting screws. In short, it’s just a subpar board with added unnecessary complications that’ve led to issues. Worth noting, I’ve used Gucci MITX boards from the Z97 Impact VII onward; they still function smoothly thanks to their superior design compared to this Gigabyte model.
