These pressure calculations for WC are accurate.

Yes, I've reviewed the sticky note and discovered a link to charliehorse55's discussion on another forum.
Even the parts used to secure the cable for input/output? Would a fitting maintain a 0.3 PSI limit when connecting the tubing to the components? Yes, it does—yielding 4.8 PSI from just the essential fittings required to fasten the tubing to the components.
It's interesting that you're questioning the rating, but the Laing D5 Strong (8-24V DC Pump) is actually listed as pumping 50PSI. This discrepancy might be worth investigating further.
This instruction clarifies the need to select a pump capable of managing the calculated pressure drop for a loop, ensuring it can handle 1 GPM at the required pressure.
You'd need precise knowledge of the pressure drop to make an informed choice based on existing hardware and pump data.
In reality, I'd opt for two DDC pumps instead of a D5, as they handle higher head pressure even with lower flow rates.
But in a tight loop, head pressure exceeds flow rate.
Consider a D5 equipped with an aftermarket top, MCP35x (with or without one), or dual MCP355 units.
The dual pump setup in a single top offers solid value (it ensures operation even if one pump fails), but don't let yourself be misled by flow rate (Q) or pressure (P). Focus on keeping your loop leak-free and straight—this is where the radiator's ability to release heat is most critical. Don't rely solely on the manufacturer's claims about heat dissipation; opt for a larger radiator that suits your setup. For a standard loop, a triple 120 mm fan (360) or a dual 140 mm fan (280) in push-pull configuration (assuming a 200W CPU, 200W GPU, plus 80W TDPs) would be ideal. Regarding the pressure drop, a D5 Vario setting 4 is adequate, or 80% DDC if you want better efficiency. Below that level, the radiator's performance drops because there isn't enough coolant flow. If your pump can move half a gallon per minute, it's a good investment. If your CPU and GPU temperatures are as high as they would be with a standard cooler and current pump, consider changing the pump position or loop order. I've personally tested this myself and achieved a 6 to 9°C reduction. Other factors matter too—pay attention to fitting shapes, fluid dynamics, and avoid sharp 90-degree bends.
