Used a 140mm Noctua NF-F12 (the pressure optimized version) as an intake fan and made one hole for the bolt as a temp mounting solution. So far temps are down from high 50s and in to the high 40s. It does look like the exhaust fan could only hold the temps stable and not cool the case if temps rose. Thanks for everyone's responses!

I did enable drive spin down for a period of time, but I've got several apps that perform library scans and I couldn't get consistent results. Will revisit this option if replacing the fan doesn't achieve some sort of results. It's a tiny case with little cooling capabilities: there's one exhaust case fan that cools the entirety. Both the CPU fan and the HBA fans are DIY, it ships with a passive cooling CPU heatsink. Cutting into the case itself is an option I've explored. I've mocked up a way to add an intake fan, but I want to continue minimizing wattage and noise. Appreciate the consideration! *stolen from the web

Thank you for the reply! The case is spotless and dust was my first thought considering the intermittent nature of my temps. I am using the Noctua NF-A12 and have a Noctua NF-F12 (pressure optimized) on order. I guess what's had me puzzled is that temps will stay cool for weeks and then once they jump, won't come back down without my intervention. It's like a hot spot is forming in the drive bay. Will report back once the case fan has been switched out.

This has been something I've been fighting for about a year and I'm finally coming to the forums for help. Over a period of a several weeks, my drive temps will run stable in the low 40s and then climb into the 60s. Powering off and letting her cool down will restart the cycle. Can you help me determine what's causing the persistent temperature climb?

I know someone will say I don't have enough cooling, but I don't understand why she's stable in the low 40s for several weeks before the temps climb and never come back down, even when not under any sort of load. I can shut down the Plex host and my temps will not drop. Thanks for your help! treasure-diagnostics-20240330-0949.zip
