tubing size question

post #1 of 5
Thread Starter 
I have recently completed my WC build on my Asus M6F mobo and blocks. Pic below



Basically I'm running 2 loops, red tubes cpu-mobo loop and clear tube GPU loop.

I'm concern about the flow rates of the loops as I used pretty long 3/8in tubes so I'm thinking if there will be an increase in flow rate if I switch to 1/2in tubes.

Or should I just switch to two loops with D5 pumps?

There will be a very small increase in flow rate, though that comes with a small decrease in pressure. 3/8" is generally the sweet spot for pressure and flow, so if you're concerned about flowrate you might consider shorter tubing runs and/or a better pump/dual pumps.

Those tube are about as short as I can go without kinking and I need the extra slack because I'm using bay XSPC X20 pump/res. A regular pump with tube res should allow me to shorten some tubing

As big as the Phantek Primoo looks, there isn't really any extra room to fit tube res on the mobo side of the case due the extra long EVGA GTX770.

I agree with CC changing tube diameter has a marginal effect on flow rate. I bay res with dual D5's would give you some very good flow rates with those short loops.

In that case you can use a bay res with a D5/DDC mount and use one of those pumps in there. smile.gif
