I purchased a Gigabyte b450m DS3H and understand the VRM aren't ideal nor the heatsink is subpar. That was within my budget. I considered the b450m Pro4 but wasn't confident about long-term build quality unless you confirm otherwise, and I’d cancel and switch. If I stick with the DS3H, can I remove the built-in heatsink and install a better one? Are there any special fans that attach to the VRM and connect via a USB port, perhaps with an internal fan design that bends over the heatsink?
The Pro 4 is superior, go ahead. Why worry about long-term durability? Also, which processor should you choose?
You can remove the heatsink and swap it out. Swapping the heatsink won’t improve the VRM performance. Which CPU are you intending to use? What kind of cooler are you employing? If you’re using a high-speed air cooler, it should help keep the VRM cool. This individual is also attaching some tiny heatsinks around the VRM—consider those for inspiration.
Without glue or soldering, it's likely you can remove it easily. Avoid handling it further; instead, install a small low-speed fan (10-12mm) above it, connected via Molex or fan header.
Hey team, I'm using a Ryzen 5 3400G and thinking about upgrading to a 3600. The issue is that online I see lots of problems reported by others—many mention DoA, fans not working, NVMe SSD issues, and some booting problems. But my setup with a DS3H/S2H seems fine so far.
S2H provides superior performance for CPU power supply compared to the other option.
