Can the main SSD heat sink on the Strix X670E-E effectively cool down a PCIe Gen 5 SSD?

[HumdrumPenguin]

I’m considering getting the Crucial T705 2TB SSD on Prime Day, and I’m wondering if my Strix X670E-E motherboard can adequately cool it to prevent early speed throttling. Additionally, since the graphics card sits right below where the SSD would go, I’m unsure if there would be any compatibility issues with the SSD that comes with its own heatsink.

 

Right now, I'm using a Samsung 970 Evo SSD on the main slot, which I'll be moving to a different slot. If using both SSDs, am I still able to keep the graphics card running at x16? The manual is not 100% clear about it, just saying that by enabling M.2_3, PCIEX16_1 WILL RUN x8 and PCIEX16_2 will run x4. But what about if I use M.2_4 for the Samsung drive?

Other considerations: CPU 7700x (upgrading to 9800X3D when available, if that matters), RAM 2x 16gb DDR5, VGA RTX 4090.

 

Thank you.

Thank you.

 

The M.2_4 slot uses chipset PCIe lanes so it doesn't impact CPU lanes.

Thank you for the reply. Does that mean that I get full speed on GPU and SSDS if using the following config?

- Crucial SSD (5.0) goes on M.2_1

- Samsung SSC (3.0) goes on M.2_4 

 

Also, do you know if the motherboard heatsink is enough for the Crucial SSD?

Yes.

 

I don't know.
