ok , I've read a few posts of the flow of water , and people have them different,

the heated water from the water block goes to the radiator , then back to the reservoir

ive also read , amdguy
Reservoir ---> Radiator ---> Water Block ---> Reservoir

so the Heated water goes back to the reservoir ?, then gets cooled before going into the waterblock ?

which is better , or is one wrong.

and yes im going towards the danger den... (away from the Leufkin kit i was originally going to get)

thanks in advance

From what I've read the water flow direction makes very little, if any, difference.

Good idea going for the DD kit over the Leufken. I have the Leufken kit, and I can see that I'll gradually have to replace every part of it (except the tubing!) to get the performance I want. I'd guess that the DD kit would yield temperatures 5-10 degrees lower than the Leufken kit, which easily justifies the extra expense.

In my case, a difference of 2.5 degrees means the difference between stability and marginal stability. In other words, at 47.5 degrees max load I can run the complete Prime95 self-test (at 10.5 x 147fsb, or 1.54ghz), but at 50 degrees I can't get through the first 3 iterations w/o a rounding error.

As a consequence, I had to remove my northbridge water block which took me from 50+ degrees at load to 47.5. I'd like to drop at least another 2.5 degrees for a better comfort zone, so I'll have to replace one or more parts of the Leufken kit--I'm leaning toward replacing the water block with a Maze2, which I think will do the trick. I'm also considering going to a bong/cooling tower, in which case my current water block would probably be sufficient.

welcome to the forum
it's definitely better to get a DD than to get leufken's kit. it's a bit more expensive but it greatly outperforms leufken. the water flow direction shouldn't make a difference as long as the water which goes through the water block is cool.

...why not read this old thread? just for kicks, huh? Basically the same question as yours but made somewhat confusing (and incorrect!) when some fella tried to reason out why there's no difference in the arrangement of WC components in the flow line and then suddenly takes a turn round and says that it might make a difference in passive cooling (fanless radiators). To me, my horse sense (ie. without producing any numbers through complicated heat transfer equations) tells me that it's of no difference.

From my experence, if you have an inline pump it doesn't seem to matter what order you have your components in. However, the pump is the submerged type, I found it better (~1.5C) to run the radiator after the resivior to dump the heat produced by the pump. This was with a rather slow 60 gph pump, with a faster submerged pump (180 gph) there was no difference in the order. Subjectively, I would run the radiator after the resivior.

1.5'C? What, the water temperature? That does sound correct if it is the temp. of the water. Waste heat (from the pump alone) is getting transferred to the water at a rate of 0.4W. Out of curiousity, is your pump's power rating 4W or 5W? But frankly speaking, the 0.4W thrown out of your pump is almost negligable to the 80 to 100W a hot-blooded Athlon would produce...
Are you sure this temp. measurement was made under the same ambient conditions?
