I'm trying to decide between fan configurations for my Hardware Labs Nemesis 360GTX radiators. Should I go with a push, pull, or push-pull (sandwich) setup for the best performance? If the performance difference is minimal and not worth the cost, I'd prefer to save some money. I'm considering a smaller case like the Lian Li O11D EVO RGB instead of the larger O11D EVO XL, especially since I'm looking at push fans on top and pull fans on the bottom. Any suggestions?

A push-pull configuration can help you dissipate about 10% more heat at the same water temperature and fan speed, which is pretty solid. But if you're considering the cost, think about using Arctic P12 Pro fans instead of those fancy wireless RGB ones—they're way cheaper and perform really well.
In general, the performance differences between push, pull, and push-pull setups are pretty marginal. Honestly, you bought a custom loop to make your build look good, so go for what you think looks best. Just make sure to tell us about your components next time so we can help more specifically!
Whether you choose push-pull or just push/pull, you might not see a huge performance difference—it really depends on your specific fans and how you've set your fan curves. For me, I didn't notice much variance in cooling performance.
If you're mainly concerned about ease of maintenance, pull configuration might be the way to go. It generally makes cleaning your setup much easier since you won't have to disassemble everything often.
