I was wondering, would it matter if you mounted a pump upside down on the top of a case instead of inside a bay or at the bottom?

Also, would it make a huge difference, if you have the heated liquid pass through the resevoir before it goes through the raidators?
 
You can mount a pump any way except for having the inlet pointing down.

Component order in a loop doesn't really matter. Temps are pretty constant throughout the loop regardless of order. Just make sure your res or 'T' line feeds your pump and you'll be fine.
 
I've had personal experience pumping into my reservoir by accident...

Let's just say it wasn't pretty. Reversing the order (pumping into the block rather than the res) netted me about a 6c drop on my X2 when I first started watercooling.

Other than that (pump TO waterblock, then res and rad or whatever) it shouldn't matter what order it's in.
 
Hmmm, I am tempted to go with a watercooled solution, was looking at the following

Two of these http://www.scan.co.uk/Products/ProductInfo.asp?WebProductID=392921

Figuring I can mount the raidiators along with the reservoir either on the top or side of the case, then put the pump in place of a harddrive cage.

Then loop wise, have the pump feed into a T-split into CPU & Gfx coolers, have those go out the back via some PCi slot holes (one into each radiator) and then feed both radiators into the reservoir and have that return back to the pump through another PCI slot hole where it joins back with the 120mm radiator hook up.
 
Don't use any splits...

A single radiator won't be able to cool a GTX and a CPU, period... Unless you add about 6 of those cape cora passives!
 
Normally, splitting isn't such a good idea. But here's what I've done and experienced good results from.

I've got a gpu block (mcw60), chipset block (mcw30), cpu block (fuzion), and two rads (coolrad22t and bip1). For pump, I have the ddc2 with petra's top.

Here's how my loop goes

pump-wye
wye1-mcw60-coolrad22t
wye2-mcw30-bip1
-wye-fuzion-pump

The fuzion is at the "end" of the loop but it's right after the two rad's and merged together for more pressure/flow.

Yeah, a well planned Wye loop can do really good things for your waterloop, but it's definitely not something you want to use unless you know the theories behind it.

Fair enough, guess I'm best off getting an external system like the Exos II if I wanted to watercool.

Out of interest though, why isn't splitting loops recomended? The way I see it, if you don't split, either your CPU or GPU ends up recieving warm water from the other.

Well, water can absorb ALOT of heat before it starts to heat up... I forget the actual stat, but it's quite a few joules. For example, water after my rad hovers around 29c, and right before the rad it's only 32c. Not a huge difference.

As for Y splits, well... Water works like electricity and anything else. Lets use a theoretical variable called a "restriction coefficient (aka r) ". Say 1 half of your Y loop has an r value of 30, and the other half has an r value of 50. Where is most of the water going to go? along the side that has the r of 30.

Water, like anything else, is LAZY. It will take the path of least resistance. And, the resistance of a block isn't always what you think it is. Unless you know the exact resistance of your blocks, and you use these values to properly split the loop into 2 seperate loops (parts of the Y) you might have LOTS of flow going to some components, and little flow going to others.

On which continent do you live? and what case are you using :)

Now, flowrate isn't all THAT important, so the difference is probably going to be minimal, but you're using way more tubing then you need to, which adds to tube clutter and generally makes for a crappy looking system.

with proper planning it can look and perform well (or better than a non Y loop), but the gains are probably small at most, and the possible losses could be rather large, especially if Aesthetics are important to you.

Probably better... but now with a GTX waterblock, you're in a price range higher than a complete DIY system... one that will perform much better with a lower sound level.
 
Hmmm, this watercooling is definately complicated, but I can see the analogies with wiring make sense.

I'm gonna try getting the air cooling right first I think then try and move up to water :)

Awwww crap, lost another one. :(
 
basically it says that you need so many joules of energy to heat 1 kg of water one degree kelvin (or celcius as they are the same scale)
