Find the VRMs on the Asus Prime B360M-A Mobo easily.
Hello. I'm facing an issue with my VRMs getting too hot on the Asus Prime B360M-A motherboard. I bought some aftermarket heatsinks with pre-applied thermal adhesive, but I'm unsure where to place them correctly. I don't have any specific guidance and haven't found detailed instructions for my board model. I've attached a picture of the PCB if that would help someone find the right advice. Thank you!
The arrangement of the Mosfets on your board suggests poor airflow, making it difficult to fit a heatsink. Consider improving ventilation or upgrading your motherboard. What indicates your VRMs are overheating?
In Intel Extreme Tuning Utility I can observe VR thermal throttling happening when the CPU is working hard.
I tried adjusting their positions earlier, but it only made a small difference. Your fan arrangement looks good—intake fans at the top, exhaust and rear fans as intended. Moving them might help, so consider experimenting with placement.
I arranged the top fans to act as exhaust vents, taking advantage of natural air movement. The remaining units were positioned for intake only to maintain positive pressure, though this likely wouldn't significantly improve VRM cooling.
Thanks for the update. The issue with fans not improving performance even when aimed at VRMs suggests a need for stronger cooling solutions. For a micro ATX form factor, consider motherboards with robust beefy VRM heatsinks—brands like ASUS, MSI, or Gigabyte often offer strong options. Look for models with high-wattage VRMs and ample heatsink coverage to ensure stability under load.
Looking for a board with VRM heatsinks is a good idea. On Newegg, MSI's B360M mortar stands out with the best heatsinks under $100. It has a modest chipset heatsink, but it should work if your existing temperatures are acceptable. You can find it on Amazon Prime for $89.99.
You're using a different CPU model on that board besides just securing it with fans and zip ties. A permanent solution for VRM overheating isn't possible without a proper heatsink or better VRM design. If the VRMs are hot, the CPU might be too large for that board or there could be a faulty VRM control setting. It seems like the board itself is likely low-cost.
