Any limit to flow rate?

[shadowman007]

First thing I want to clear is i will be running 2x EK D5 pumps in series the specs are for each pump as follows:

Mximum pressure head: up to 3.9m

Maximum flow: up to 1500L/h.

Know what I wanted to know is there a limit on flow rate? what i mean is there a certain maximum where after this it will not matter if the flow rate number is any higher? If there is no max then i guess having the fastest flow rate would be better? maybe some temp drop since water would be moving fast?

How does a coolants temperature effect the flow rate so drastically?

no...the flow rate affects the temperature

you're reading the graph backwards

I'm an idiot.

lol

 

anyway, clearly the 25L/min of the D5 is more than enough, running it at more than half speed gives negligible improvement

I really wanna water cool- but I've never done it before and only like hard line.

Its not that hard, just takes a bit of patience and willingness to learn.

I think I spent 4-5 hours and 5 fails to get 2 finished tubes, when I had never done it before.

My real world experience is that if your pump is moving any water then that's sufficient.
