Finally took pictures of my rig

[Bigedmond]

I was getting ready to clean it, so i decided to snap a couple shots of it.

Nice! How are your temps with that koolance system?

[Bigedmond]

never higher then 36c. it does what i ask it, and i have pushed it with some rendering operations in 3DS Max.

Very nice! Looks like it was definitely due for a cleaning too
I'm not very versed in watercooling, so please excuse the lame question. But why are there two tubes coming out of your CPU waterblock that get forced down to one tube of what looks like the same diameter? That seems like it would be a little self defeating.

I would think that the two tubes that merge into a single tube would be the lines that remove hot water, while the single tube in the middle between the two tubes is the cool water. Since the two tubes perform the same function, removing hot water from the block, it makes sense to merge them into the same return line back to the resevoir.

Of course, this could be done vice versa as well, I suppose, where the single tube in the middle removes the hot water, while the two outside tubes that are connected to a single tube are what provides the cool water to the block.

Yes that would make since, if the 2 tubes going into one didn't run down to the GPU block.

Haha, the Latest Post list said "Finally took pictures of my...". I didn't really want to click on it.

Looks good!

I just don't get why you would bother having two tubes pulling water out seeing as it would be limited by the single tube flowing water in as well as the "bottleneck" of the two tubes down to one. Why not just have one tube for in and out or two tubes for both in and out? I guess I'm not questioning why you have the two tubes coming back into one (I can understand that), but why would a company design such a waterblock to make things complicated, does it really offer better performance somehow?

Being a plumber, I think I can help with this. The way the block is set up, the "COLD" water hits in the middle of the block, the other two lines bring the water to the outsides on the return. This helps the block stay cooler and keep a better overall temp over the whole block. Bailey

The block in question is a Danger Den BTX. The design was to have one connection go to the chipset and the the other to the GPU. Ideally a res with multiple inlets would eliminate the restrictive y connection. Later when the TDX block was released the performance was just the same but used less copper for manufacturing of the block. But in the end it is up to the end user to find a "working" solution, as here, we have a combo DD and Koolance set up that performs just fine.

What the BTX and TDX blocks have in common is the "Jet" inserts that can fine tune the water inlet.
