Tube length

Hi all..

First post here :)

Just a quick question about tube length. I'll be giving my setup a overhaul soon and maxing a custome 'water box' containing all my cooling goodies. This will set below my case with the tubes going up the back of the PC to the CPU block.

So, does tube length have an impact on cooling ability etc? The system will have around 6 foot of Clearflex 60..

Cheers,
OP :)

Yes, it does impact overall flow rates and such.
The less tubing, the better.
Having an extra foot or two probably won't kill your cooling ability but, it's best to minimize tubing length.
 
The longer the tubing the lower the flow rate. be careful not to exceed the max head distance of your pump. My external box sits under my system also and is connected by about 3 feet of tubing. I'm using a DD D4 12v pump with around 10 feet of head, so it still fllows extremely well.

I'm using the Ehiem 1250 so I think I should be safe to have a similar configuration to you. :)

The head rating of the pump is vertical head, it doesn't mean 10ft of tubing. It means it can pump water 10ft high. In a closed loop this is irrelevant, because only frictional forces impact fluid flow. Pipe length, bends, and other pressure drops can be converted to head losses, but it would be pretty difficult to do so with waterblocks, all kinds of different-radius bends, etc.
 
Thanks for all the info guys. I've done a few designs over the weekend and think I'll need about 5' or tubing to do the system. Don't think thats too bad considering the water cooling gear is situated below the PC case.. Will keep you updated with pics as and when things happen :)
