Which SSD heatsink for the M2_2 slot on the MSI PRO Z790-P WiFi DDR5 mainboard?

Choosing the Right SSD Heatsink for the M.2_2 Slot on the MSI PRO Z790-P WIFI DDR5 Motherboard

When building a high-performance PC with the MSI PRO Z790-P WIFI DDR5 motherboard, selecting appropriate cooling solutions for your M.2 SSDs is crucial — especially for the second M.2 slot (M.2_2). Located beneath the graphics card, this slot presents unique challenges due to limited space and proximity to other components.

Understanding the M.2_2 Slot Location

The M.2_2 slot on the MSI PRO Z790-P WIFI DDR5 motherboard is positioned under the primary PCIe x16 slot (GPU slot) and is situated to the left of the “PRO Series” logo on the motherboard. Because of its placement—directly behind the GPU—it is largely concealed once the graphics card is installed. This hidden positioning makes cooling considerations more complex, as traditional heatsinks may be bulky or interfere with other components.

Challenges in Cooling M.2 SSDs Behind the GPU

Effective thermal management is vital for M.2 SSDs to maintain optimal performance and longevity. Overheating can lead to throttling, reduced speeds, and shortened device lifespan. Given the limited space behind the GPU, selecting a heatsink that is both efficient and compact is essential.

Recommended Heatsink Options

Considering the spatial constraints, here are some suitable heatsink options for the M.2_2 slot:

1. Low-Profile Aluminum Heatsinks: These heatsinks are slim and lightweight, designed specifically for tight spaces. They typically attach with thermal adhesive or simple mounting mechanisms.

2. Clip-On or Socket Heatsinks: Some low-profile heatsinks are designed to clip onto the SSD without requiring extensive installation space.

3. Integrated Heatsink Modules: Certain M.2 SSDs come with built-in heatsinks tailored for compact mounting — like the WD Black SN850X 2TB SSD, which you mentioned planning to purchase. While these are often pre-attached, ensure they fit within your motherboard’s available space.

Additional Tips

• Consider using a mounting bracket or a heatsink designed explicitly for confined spaces.
• Ensure that the heatsink does not obstruct other components or airflow within the case.
• If possible, verify the maximum height allowance behind the GPU to select a heatsink of compatible dimensions.

Conclusion

For the M.2_2 slot on the MSI PRO Z790-P WIFI DDR5 motherboard, due to its
