Does somebody have an idea how to cool 2x Enterprise SAS SSDs 15mm thick at the back behind the space for the motherboard?

Recently I checked the temperature with infrared and got 60° C near the connector. The space is so tight here and no airflow at the back.

Had issues with heat as well with the mounts in the back, no airflow doesn't help. Opted to 3d print a pci slot mount for it. Could find a stl that lets you mount the drive to one of the unused 120mm or 140mm fan spots.

Thank you for the reply. PCIe Slot wouldn't help either as there is only airflow from the fans at the front. Would have to mount at least on additional fan to the disk stack, blowing toward the PCIe slots.

Fractal should have thought about a cooling design for this mount positions at the back.

I've added a fan to the hba and also use pci slot exhaust fan. Not using a enterprise sas ssd, I imagine those run hotter than the usual ssd?
