Tubing Length??

[generallee989]

Hi all,

Thanks again for all the help with the fan/radiator placement questions I had. I finally got the system running. There are a few more things I wall be adding to it in the next week, just couldnt wait and got too excited

This is my question now:

I have only the CPU being cooled right now and Im at 42*C under load.
The tube from the pump going to the waterblock is about 3 feet long spiraling through the case.

Will I get a more efficient cooling with a shorter tube?

Spec:
Intel DP55KG motherboard
i7 870 2.93 CPU OC'd to 3.6
Patriot Sector 5 1600MHz DDR3 x16gb
AMD/MSI HD6950 Reference Board unlocked to HD6970 spec
1000 Watt Antec PSU

Here is the pic of my system:

wow that's a lot of 'green spaghetti'.

in a word yes, longer tubing can affect your cooling performance tho that is dependant on the pump. if you have a pump with low head pressure, your flow rate will fall below the sweet spot of 1 gallon (4.5 litres) per minute. if you have a decent pump like a D5/655 or DDC/355 then based on the quick look at your loop, you should be fine.
having said that, you could probably chop your loop length down a bit with better routing.

That looks like a jingway...something (can't remember the name) which DD sells as a DD CPX Pro. Those have 4m max height and 3.5gpm so should be fine.

But yes, you could route things better! Though I do kind of like the look or lots of tubes!

Thanks guys/gals,

I'm waiting for the reservior to show up and will switch around the tubing then so that the shorter goes streight to the CPU.

I was also thinking that with a longer tube going away from the CPU, would it dissipate the heal a little more going into the radiator? Making the overall temp a little lower?

I feel that it should be a little lower on temps. I also have the fans blowing from inside the case through the radiator out. I know fresh air would cool it down more but am worried about pushing too much heat in the case itself.

As long as the air is being vented somewhere else it doesn't matter that it's sucking it in. Slightly warm air isn't going to affect much inside, and as long as the air is cooler than the components it will still cool them.

A long tube of water is unlikely to add much cooling, as the tubing isn't going to radiate much heat (unless it was made of copper). More water in the loop, means it needs more energy to raise the average temperature of the fluid, which wont really reduce temperatures overall but will mean the raising/falling of water temperatures will be more gradual. SO it wont be cooler, but the peaks will be smoother.

This makes perfect sense. Thank you Princess.

My problem is that I always make it the right length, (so I think) until I want to remove something or change a part then its a pain, and wish I left the extra length - and kicking myself for not remembering.

But that was until I found about quick connect fittings.
