Insulate Your Water Tubing

post #1 of 33
Thread Starter 
I've noticed that I am unable to find an FAQ for insulating your tubing within your case. I don't quite understand why all of the pics I see have the tubing exposed to the heat of the case. You may want the bling, but in actuality, by using foam tubing used for copper piping during winter, I see a 4C drop from my idle temps, but only a 2C drop from my load temps. But hey, every bit counts right? Should I make an FAQ regarding such?

Basic Rundown:

eyeball length of internal tubing(the part of the tubing inside the case, people)
cut foam piping insulation that has its inner diameter matching that of the outer diameter of the water tubing.
Use thermal tape used for ducting or even thermal epoxy from Kragen or Autozone to make a very tight seal.

All in all this will protect your water as it passes through the much heated case temps as it travels to your important cpu and/or gpu. Anyone ever heard of this before? Don't want to step on toes here. Thanks...

its not to bad an idea but in all actuality i think you would want the tubing to radiate out instead of keeping the heat in but i havnt tested it
plus the tygon and such usually acts like an insulater anyways but if you got temp decreases good deal

i really don't think it makes that big of a diffrence. theres not enough heat exchange and temp variation in your lines to go through the trouble.

The thing is I can add fans and only see a 1c drop, but I can touch my wc lines and the temp feels the same as everything other object in my room. So im sceptical of your temp drops. unless maybe you have a super hot case with dead air spots

My case temps are always lower than my cpu temp and thats the way it should be. So i don't have to worry about insulating anything

it seems to me this would only be a problem if the cold line(s) were located directly on or near a known heat zone, like say, resting on the southbridge chipset heatsink, or right near the power supply... maybe a really hot HDD?

Caregul use of a couple fans and good line positioning would probably yield similar results without screwing up the bling factor (which is pretty IMO, one third of the allure of watercooling to me is the tubing, and getting to use GREEEEEEEEEEN! auto antifreeze)

Yeah... I don't see how insulating your tubing will help. In fact, it would only INCREASE water temps. First... as DigitrevX said, the delta between ambient temp and water temp is quite low. A few degrees at most so there will be little transfer of energy especially with some thick tubing. Second, you WANT the warmer water to transfer its energy into the air. As long as the heat isn't sitting in your processor. I have seen mods where ppl used copper piping instead of plastic tubing. The pipes act as an additional source of radiation. However, temp impact was less than 2-3C.

The only time insulation is needed is when you have lower than ambient water temps. This is to reduce condensation and keep from ambient air temp from heating up the water.
Once again...

The reason why you wouldn't insulate tubes is that there isn't a big temperature differential between the water inside the lines and the ambient air inside the case. It's what makes water an excellent coolant, its specific heat is very high, so it can absorb a lot of energy as heat without increasing its temperature.

Tygon/PVC tubing is pretty insulative, too.

I'm glad your getting a nice temp drop doing that...Do you have a super hot case temp? I've heard people say that they got a 1-2C using Swifty cool coils to...I haven't noticed any drop with them... I don't see how that is dropping your temps, but if it is it is...People usually insulate their tubing when they go sub-ambient to control condensation....

I think you guys may be missing the point. How many of you have your tubing passing somewhere near your GPU or Northbridge? And, regardless of your cases ambient temps, to radiate that heat into the case will only increase your overall operating temp. Keep in mind you only insulate the tubing inside the case, not out to the radiator or pump. This would definitely not work on a completely internal water kit, but I guess I should have made that more clear. Unfortunately, my only option is to have my tubing follow over my Northbridge and top of my video card, so maybe it only makes sense for me. Thanks for the input guys.

Who cares about temps near the CPU/GPU? The temp IN the CPU/GPU is what is important. You can completely insulate your waterblock and tubing. This will slightly reduce case temps... but will also slightly increase GPU/CPU temps. You want the heat out of your processors. As long as the air has some flow, case temps don't matter because the vast majority of the thermal energy is being dissipated by the radiator.

You need to read up a bit. When your tubing is close to the intake line for the block, and is under load, many people 80-100C on load with the gpu, and this heat is transferred to the water which is passing into the block, which you just so happened to try and cool to the room temperature where you computer is located. It's like holding a lighter 2 inches from your tubing. And yes duck boy, people care about their temps all over, not just cpu/gpu...
