Is there a limit on length?

post #1 of 21
Thread Starter 
Simple question, is there a length in tubing you want to stay away from, or does it matter. I know longer tubes will mean MORE coolant in the system, that's not a bad thing is it?

Ah...forgot one question, How many liters, gallons, quarts, whatever your measurement maybe you use for coolant? IS there and obvious TOO much?

thanks again for all your info guys....

More tubing means more restriction but it isn't too bad of an increase unless you're talking about a few yards.

I used about 40oz of water for my loop. Water amount does not matter too much. Having more water slows temperature increases and decreases.

i.e. It takes 10mins for CPU to hit 40C in a 50oz loop (and the reverse to cool down).
It takes 20 mins for a CPU to hit 40C in a 100oz loop (and the reverse to cool down).
In the end, it still hits the same max temp.
Once again...

provided your loop is closed you can use all the tubing you want... if you want to run some copper lines in your new sprinkler system trenches go for it!

large amounts of tubing will increase startup loads on your pump, but once the coolant comes up to speed, even with 100ft of tubing you're not going to lose that much speed... and it won't be enough to change your temps by more then a degree... but that tubing itself will radiate a very small amount of heat so you may overcome the added loaded pump heat injected into the loop...

just try to keep in mind that more pipe = More water. More water = not usually a good thing when you only have a 150L/H Pump. It's much like a fishtank in hindsight. you can't just Keep your tank Clean using a Filter Make for a Goldfish bowl. needs to have enough volume movement otherwise it'll just Load Full of Ugly Green Algae.

Agreed. as long as it is a decent pump and you aren't running it around your room, you should be OK. I have to admit, when I filled my first loop, I was amazed at how little fluid is in the loop. I think my current set-up uses 500cc or so.

Tubing's walls aren't perfectly flat so they do cause restriction.

D5 Pump + FuZion + 1ft tubing = 2.03GPM
D5 Pump + FuZion + 25ft tubing = 1.74GPM

Just someone PLEASE Promise me they wont ever get as bored as i did, and wrote "WEEEEE!!!!" on the wall using Water cooling pipe. unless your running it on a 500L/H+ Pump. AND WHO STOLE MY NETWORK CABLE CRIMPER?! i hate trying to look for things at 4 in the morning.

OK....well what about Res size....this was where i was getting to.....I have some plans for a res, I'll have to figure the volume of it tho....but lets say around 20 to 24 ounces, but I don't plan on keeping it competely full. OR should I keep it full because of the chance of air in the system?

REP all around!
