I just need an opinion on this kit that i custom built from DangerDen for an AMD Athlon-64(939).
Also, where would I place the pump?
Is it necessary to have a resovoir?

Peltier/TEC:	None
Pumps:	Eheim 1250 with 1/2" Adaptors
Tubing:	10 Feet of UV Blue

Thanks.

[EDIT]
Also, The hose clamps are what holds the hose to the barbs, right?
[/EDIT]

I would get a TDX instead of the RBX personally.

Consider the 12V DD pump. I have heard very good things.

any reasoning on the tdx/rdx?

Works better. Sits more stable on the core. 2 barbs instead of 3.

Also, to answer your other questions:

1. With both the TDX and RBX, the pump should go directly in front of the waterblock.

2. You don't need a res. You do however need an air trap. This can be a res, a "T" line, or a fill & bleed circuit.

3. Yes, the clamps seal the hose to the barb, and help prevent leaks.

Thanks for the help but I still have one more question.

For the resonably low price of a res. what do I gain over a T?

none. there are arguable bonuses, but no, not really. also, are you interested in graphics block? the new Maze 4 is 6800 capapble so you dont have to shell out 100 something for a waterblock. (they should be out soon if they arent already)

I'm pretty sure I am going to buy this system.

I have seen different theories on what order to put things in.
What do you guys suggest?

res/T-line > pump > rad > CPU > GPU

I'm with Put, TDX over RBX. Both utilize the same jet-channel setup, in fact the TDX is an RBX rotated 90 degress with a small barrier put up so it only needs 2 barbs. Plus is has a fatter base so mounted is more complete.

As for pump, get the a 12v pump DD D4 for 1/2" over the Eheim. The D4 offers 12' of head to the Eheims 6'. Since both offer the same max flow this means that at any given amount of head (resistance) other than zero the D4 will outpreform the Eheim. Then you have the added benefit that the D4 is only on when your system is on. Finally I do not think there is much of a noise difference between the two. and the D4 is about 1/2 the size of the Eheim (maybe even smaller)

With your help I think that I have worked out the kinks.

I do not have the budget right now to go with the maze4 gpu block but will add it to my loop at a later date.

Looks like a great setup. No problem with getting a gpu block later, your pump and rad can handle it with ease. Also good job for selecting 10 feet of tubing you will need about 5 feet but if you measure and cut like me you will need that much (also its good to have extra, you never know what will happen later with a new case, blocks, etc... ).

With the TDX working on the impingement principle, I maintain that the pump should directly preceed the water block. Therefore:

res > pump > TDX > rad > res

You can see my thoughts on the best fill system and air trap here:

http://guides.pcapex.com/water_cooli...ine_system.php

hmm... just check out the pump's specs (the arent listed at DD.com) but i think that may be ogin in my setup now.... (if i have the cash to spare)

Great guide but for my purposes I believe a res. will be easier.

When I add a GPU block the loop should then be:

res > pump > TDX>GPU > rad > res

?

(total came to $299.49 w/ shipping ...eeek....)

Yup thats perfect.

sounds good. Put knows what he's talking about. Personally I like having the coldest water (from Rad) go strait to my CPU but thats me.

But Put, as far as the Jet blocks go.. we're talking about a relatively closed loop meaning the water won't be moving faster at point A than at point B so why does placing the pump before the TDX instead of the Rad make a positive difference? the only real flow difference I could see would be going RES > CPU and thats just a maybe...

Realistically, any difference will be slight. However, the maximum pressure (on which the impingement blocks depend) has got to immediately off the pump. I am no physicist, but it just plain has to be.

By the same token, the whole system will reach thermal equilibrium 5 minutes after booting up ...... so the rad before block theory doesn't really hold water either.

At the end of the day, we are talking fractions of a degree. Component order is not going to make or break a cooling system.

Will the addition of a GPU block lower the cooling ability of the loop on the CPU?

Thats why I am a big fan of trying to use least amount of tubing and avoid sharp turns to get the best temps. Order doesn't really matter in my opinion either.




Also adding a gpu will add some heat into the loop but not much (nothing to worry about).

Does that mean a couple of degrees celcius on the processor or a more negligible amount?

I'm not sure on a exact amount but my guess would be 1-3c degrees.
