Watercooling setup question

ok, right now I have the radiator with two 120m fans behide a wall with a dryer duct pushing cold AC air into the intake fan. Right now the hose length is about 3-4ft in each way and works just fine.

I was thinking of moving my desk but if I do and want to keep the setup the same, the hose length will have be more like 16-18ft each way.

Would this be to much for a 500Gph pump??
 
That depends on the pump you're using now and how many blocks you have in your loop. But yeah, a bigger pump sounds good, or maybe a second identical pump hooked up in series. BTW, this sounds like a kickass ghetto cooler. :thumbsup: Pictures?
 
Only two blocks, cpu and gpu.

ghetto is not the word for it but give me a few hours/days and I'll see about getting some pics

It looks like you got a reason to hook up two pumps in series.

I look forward to seeing it.
 
Go to an Eheim 1260(~700GPh), and you should be fine with that setup.

I'd be worried about someone or something putting a crimp in the line though. I'm so paranoid that I've crammed mine all inside my case.
 
What kind of pump do you have? The head rating is what is important.
If you use 3/4" ID tubing then there will be very little pressure drop. I was using an eheim 1250 (6' head) to push water through 50' of 3/4" copper and got a pretty good flow rate. I ended up getting an Iwaki 20RZ to improve performance with my Cascade block.
 
do you really need that ac air? just get more 120mm and put them in series on your radiators. radiators are rather dense, air has to be forced through em quite hard.

Being that radiators are designed for easy airflow and maximum heat transfer I doubt brute force is really needed. Couple this with push-pull configuration of the fans (matched set of course), which "cleans" the flow of air from front to back of the radiator, and you have the ability to easily low-volt without losing much efficiency.
 
i don't know about that. the radiators i've seen are rather densely built, they are anything but free flowing. the types of fans used have very low static pressure ratings u know..

hmm wait.. push pull is series😛 with decent cowls on each side, it works great. in series they double the static pressure.. force the air through better.

I have no experience using heater cores. Is that the type of radiator you're speaking of? The rad I'm using can't by any stretch be thought of as ubstructive.

That pump will work fine. You should consider getting some cheap 3/4" hose for the 18' run. But either way it will work fine.
