I recently got a new case, the DarkFlash DB330M, and I just found out that it doesn't have a dedicated slot for front intake fans—only the bottom. The issue is that my motherboard's PCIe slots align with the middle of the case rather than the top two slots, so I don't have room for bottom intakes either. Right now, I've got three exhaust fans (top and rear) and I'm adding a Phantom Spirit 120 SE cooler for my CPU, which should help keep things cooler. I've done some test runs and the temps seem manageable, but I'm worried about future upgrades. I'm planning to get a slimmer three-fan GPU, and I hope my new motherboard will fit the top PCIe slots instead of the middle ones. If I can't find a GPU that allows for intake fans, will I run into temperature issues? What's the best way to improve airflow in my setup?

Short answer: no, it's not ideal to skip on intake fans. You might not face immediate component failures, but without intake, your system could overheat under load, especially in longer sessions. GPU and CPU throttling will really hurt performance. Also, not sure why you’re having PCIe alignment issues; every GPU should fit the same way, so check your compatibility with the case and motherboard!
Going fanless on intake means your exhaust fans are just pushing hot air without bringing in cooler air, which isn’t great. Your cooling system will struggle because air pressure will pull in air through cracks and openings instead. That’s not optimal for keeping things cool!
Absolutely, you need some intake fans. I once had a full exhaust setup in my case, and adding just three intake fans dropped my temps by 10-15 degrees Celsius. Trust me, it makes a huge difference!
You could try flipping some of your exhaust fans to work as intakes instead. It might help with airflow a bit!
Wait a minute, how can your PCIe slots not line up with your case? That sounds like there might be a mix-up with your motherboard. Make sure it’s a standard ATX board and not some odd proprietary setup. Otherwise, you might be in for a headache later.
Yeah, I think you're right—sounds like they might have a board that’s not following the usual layout. Double-check that!
