I'm setting up a similar configuration to yours with the same case, motherboard, and fan. Could you tell me more about your experience? Please share your temperatures on the top card and let me know if it's with the side panel closed. I want to understand whether the temperature difference is an issue or just minor. I'm okay with some throttling on the top card.
I completely overhauled my configuration recently. I experimented with Asrock recommendations but ran into issues because of the lack of SLI support and explicit multi-GPU configurations. The meshify C didn’t perform well—my bottom card struggled with airflow, and the top card was overheating significantly. With the meshify C, temperatures were around 78°C on top versus about 75°C at the bottom. If I switch to an AMD setup, the only viable option seems to be the MSI X570 Godlike, which leaves no room for the Meshify C due to the E-ATX motherboard size. I ended up using a Coolermaster HAF XB Evo, allowing better cooling for the bottom card. Under heavy load, my top GPU rarely exceeded 75°C, averaging around 70°C at full power, while the bottom stayed near 60°C at 85% fan speed.
Thanks for the input! It seems you've covered many similar challenges before. Great to know your current configuration is holding up. The 78°C top card is a solid number, especially since you're coming from a high-temperature setup. Your question about the temperature difference between the top and bottom cards is clear—do you mean ~78°C at the top and ~55°C at the bottom? I’m trying to balance performance with what I can realistically adjust. I’m not looking to overhaul everything, just make it work better with what I have. I’m leaning toward a cooler with more spacing between cards for better airflow, but I want to confirm if that’s the best trade-off. Your blower card setup should help with exhaust, so that’s a plus.
I initially placed the second GPU on the Asus TUF board, but there wasn’t enough room because the PCIe slots had standard spacing. In that case, the top card was at 85 degrees, which I found too high and not suitable for SLI. Keep in mind that the current SLI bridge for the 3090 requires four slots apart, making the X570 the only viable option. Edit: I plan to share a build log with photos soon.
Thank you for the details. I'll keep an eye on your future updates. Right now, my scenario doesn't need SLI since my work stays within the capacity of one GPU.
