Exprience With High Flow Fittings? Pointless?

Exprience With High Flow Fittings?

To me high flow fittings seems pointless, as the waterblock have much lesser space for water to pass through meaning its a few times more resrtive than a fitting with 8MM iner diamider.

However, has anyone exprienced where using high flow fittings has increaced flow rate?

Yep that's pretty much it. In a water cooling loop you have a collection of parts with varying levels of restriction. The total restriction determines the flow rate.

Of that total restriction number, if you break it down is normally say 80 or 90% the blocks and the rest tubing and fittings. By changing the tubing or fittings you might lower their restriction by say 30%. However that only makes a small change to the overall number because it's 30% of 10% of the total.

You are basically lowering the restriction of what is already the lowest part of the system.

I was thinking that water flow would be detriminded by the part that is the most resctrive part in the loop. Yes no?

Fittings might have restriction but is extremly low, but lowering it even further will improve flow rate?
Zero effect on flow or minor effect?

Are there examples and exprients done online that had proved this?

They have a minor effect on flow rates - Nothing to lose much sleep over for most builds...

All restrictions add up. So it's not just about the most restrictive part. That said, unless fittings are somehow responsible for most restriction in your loop, the effect is minor.

Any websites or information on how the flow rate would be effected by resiction?
