VRMs overheating?
VRMs overheating?
You've got a Gigabyte Aorus M with Ryzen 3 2200G and a Deepcool gammax GTE V2 cooler. After some tweaks, you managed to push the CPU to 4.0GHz and the iGPU, but faced a Windows blue screen during stress tests. Restarting helped, but crashes continued. From the hardware info, temperatures reached 110°C with both components under load, and crashes occurred above 120°C. You're looking to keep pushing for better performance. Consider checking thermal paste, ensuring proper airflow, and monitoring temperatures closely. If you need further guidance on diagnostics or adjustments, let me know.
Provide airflow to those SoC VRMs located on the top section of the board, away from the left-hand side near the rear IO.
120c is expected to cause your board to crash or limit the CPU performance. Install a fan and point it toward the SoC VRM.
You aim to assist the transistors that transform 12 volts into the voltages needed by the graphics card for cooling. Simply positioning a fan over the motherboard area can provide some relief, but placing heatsinks on the chips helps move heat from their small surfaces into the cooler air pushed by fans. You should purchase thermal pads or VGA pads (small squares or rectangles with fine pins or ridges) and apply them using thermal adhesive tape. Remove the protective film from the tape, then press the pads onto the chips for roughly ten seconds. Before applying, lightly wipe the chip surfaces with sanitizing alcohol or isopropyl alcohol and let them dry. Cover the chips with yellow pads, as shown. The orange square houses the controller, which manages all components; the main VRM sits beneath a large metal heatsink, while the secondary VRM powers the graphics and typically lacks heatsinks. Unless you buy extra heatsinks, it’s unnecessary to attach one to the controller. A single heatsink can cover several chips, so you don’t need tiny, precise pieces. Look for pads with at least a few millimeters of height and ridges, avoiding overly thick metal sheets. Good options include: https://www.amazon.com/Easycargo-Heatsin...079FP1FWR/ for a compact fit, https://www.amazon.com/Enzotech-Graphics...002BWXW6E/ for a bit more, and https://www.amazon.com/Easycargo-Heatsin...079FQ22LK/ for smaller sizes. Multiple pads under 14x14mm usually work well, especially when paired with a fan blowing over the fins. More surface area from additional pins or ridges helps dissipate heat more effectively.
Consider your cooling setup carefully. Choose heatsinks that balance performance and space, ensuring they don’t interfere with your CPU cooling. These should lower peak temps by 10-15°C or more. Keeping VRMs under 110°C will keep everything stable. MOSFETs rated for higher temps are fine, but aim for the board to stay below 100-105°C long-term. This prevents the circuit board’s fiberglass from degrading due to heat, which can lead to faulty connections. Position a fan at an angle near the CPU and ATX cable to direct airflow toward the board. For a more robust option, consider a squirrel cage fan similar to those in laptops. You can find suitable models on DigiKey, for example, the CBM-6015V-150 from NMB Technologies.
