Hi

guys Ive been thinking about starting an AXP project and liquid cool it (bored I guess ), but there is one thing I dont get, why use a rad and a reservoir ? if the rad is big enough isnt there enough liquid in the loop ? (the zalman for ex doesnt use one, Im sure of it, not enough space in there for both )

also I plan to ice the rad, whats a good liquid and pump to use if the liquid is iced ? any advise on isolation would also be very welcome

please advise

Thanks
Dan

The reservoir allows liquid levels to fluctuate without introducing air into the system (air compromises cooling ability) and the reservoir acts to remove air by allowing it to bubble to the top of the reservoir, again keeping air out of the cooling loop. Also a reservoir allows for fluid expansion and out gassing during heating cycles. So a reservoir is a good idea.

Would it work ok with a fillport, like the Danger Den one?

oh ok, thanks

just to add. a few older weeker pumps get starved at the inlet of the pump and its proven that in systems using certian pumps a small res will reduce the cavitation at the pump inlet.

when designing a res ideally you dont want a large volume . thats why cylinders with res inlet at top and outlet at bottom are good because it can reduce tubing used and bleed your system easily.

If you are asking if you have to use both a radiator and reservoir, the answer is you should always use a radiator, but if you use a T-line, you don't have to use a reservoir.

Hi

yes, I was wondering if it would be possible to skip the reservoir
btw what is a t-line ? sorry a bit new to watercooling

Thanks

A T line is a reservoir of sorts.

Read that article. You'll notice he has a picture of a water-cooled PC with a T line. (It's the tubing that goes higher than the rest of the loop. He labeled it an "Expansion Tube.") I don't think he capped it in that picture. However, I would recommend you do cap it if you implement a T in your system.

PS: This is an older article, but still quite relevant. Think of it as a primer.

T-Lines are super easy and work great. I have been using one in my system for a long time and will do it again on my next system.

Here is a pic of my systme - you can see the T-line is just after the radiator - you just take a T jount and have the top go up somewhere in the case and then cap it off ( I am using an aquarium cork ) - this does everything resoviour does and saves you money and space.

Right, what Cmanser said. Do a forum search on T-line and you'll get lots of info. Here is a pic of Senator Cache's rig to give you another visual (T-line is the vertical tube to the right).

Water is the medium used to move heat from the cpu to the radiatior. More water is not the goal, just removal of air is.
If the radiator was oriented with the in/out barbs at the bottom, and you were to place a plug into the top tank of your radiator, that would work too. Although you can't see into it to tell when more water is needed to replace the displaced air.
You could also place a section of tubing attached to the top tank of your rad to work as a T-line. Difficult to do, so a reservior/tline is handier.

Thanks guys !
