## Questions & Answers

**Q: What does "*limited to use standalone peripheral (molex) 4pin cable to connect to each peripheral (molex) 4pin port from psu" mean (documentation)?**
A: It means you should connect each peripheral (molex) connector with one single cable from the power supply. So you should have two separate cables from the power supply connecting to the two peripheral (molex) connectors on RM43-320-RS's backplane directly. Do not connect both connectors on the backplane with just one cable!

**Q: Do you need to plug in both 4pin molex connectors per backplane?**
A: Yes you do.

**Q: What CPU cooler are you using for this? Does the NH-D12 fit?**
A: The RM43-320-RS can fit CPU cooler up to 148mm in height. According to Noctua's product page, the NH-D12L is 145mm tall so yes, it will fit in the case.

**Q: I see the that the chassis supports up to 148mm clearance for cpu cooler, can a 151mm cooler be made to fit in here?**
A: Probably not, we set the 148mm limit because that's all the room available for it.
