Do I Have Low Flow?

post #1 of 4
Thread Starter 
Hey guys,

Since the beginning of my first WC rig, I have thought I may have had low flow. I have been doing some reading and such as its coming up on 6 months now and I want to flush and clean as well as replace my tubing.

My question to you is 2.4 to 2.7 Lpm to low of flow? I am measuring this via a Koolance FM-17 flowmeter hooked up to my Koolance CTR-CD12.

I am using 2 Koolance PMP-450's in series on my RP-452X2.


Please discuss.......

Do you have the switch set that corresponds with your correct tubing ID?
The meter over rates slightly but these numbers can change with fluid temps and complex loops with lots of fittings, parallel blocks, etc.

~3750 is considered the "ideal" approx 1gal/minute flow however performance certainly won't be too bad at your flow rates.

What's in your loop?

Fluid type can also affect this reading. If the specific gravity and viscosity differs greatly from distilled water its numbers will be off as well.

The switches are all set up correct.

I do have a lot of Koolance swivel 90's and 45's in the loop, maybe total of 14 all together. I have a 680 koolance parallel set up along with mobo blocks for my Sabertooth x79 and of course a cpu block.

I run one of each 360 , 240 , 140 rads.

I use the Koolance coolant.

The flow with everything you're running sounds about right even with two pumps.
