I was recently working on my dads pc and noticed is loop is

RES>PUMP>CPU>TRIPLERAD

and i said he had it set up wrong but he is getting sub 30 temps on a i7 920@4ghz and not going over 70 which i thought was pretty good with the following parts

Thermaltake Triple rad built into Kandaulf LCS with 3 low pwer thermaltake fans
Thermaltake 500 L/H pump res combo
EK supreme HF

his reasoning to this was the same as a car as it is pumped through the heat source then cooled with the rad

at the minute i have got the block of his old 775 platform which is a the full copper heatkiller which iam thinking off swapping my htpc loop which is cooling a i7 920@ 3.6 on a asus p6t-se which has 775 mounting holes and has the following parts

xspc 200 pump/res combo
thermochill PA120.1 with 2x 2000rpm fans push and pull
and a Thermalright XWB-1 (which is a old 775 block)

and is setup

RES/PUMP>RAD>CPU

and am thinking of changing it to ..

RES/PUMP>CPU>RAD

as wouldnt this improve the heat dissipation efficiency of the rad but would it work well in my case just having a single rad ? and also having the res pump sat above 4 harddrives ? where as my dads res and pump is sat at teh bottem front of the case infront a fan

any ideas and input welcome looking at doing this tomorrow as well as installing an SSD

im not sure it would make any difference:

1) in this one, it is rad before cpu so you are cooling before heating

2) in this one it is cpu before rad so you are heating before cooling

it *shouldnt* make that much of a difference, but you;d hav to test and find out :)
 
If there is a difference it would be virtually non-existant and if the loops are working and temps aren't too high then nothing to worry about. The water temperature difference between min and max over a whole loop is only going to be around 1C - 2C which is why 99.9% of the time loop order isn't critical.

Edit: As for testing it, would be interesting to know the results though I think tests have already been done on temp delta's of rads just look at some of martin or skinnees tests.

Guess the easiest way to look at it is cpu + 10C but rad is -10C so you get either +10 - 10 or - 10 +10 leaving no difference.

Well its gonna have to be took apart change the cpu block

so mers well try it and do you think there will be much difference between the two cpu blocks?
 
As long as there is adequate flow rate, water temperature equalizes across loop. Component order does not matter one jot, as has been documented in many places many times before :p.

that took me a few times to understand - "so may as well try it.." :p :p :p

anyway, yeah, if you are dismantling it anyway, try it :)
 
I also run RES/Pump>CPU>Rad and my temps are rather good at present on my new rig. An i7 2600k @ 4.5ghz running at 40c idle, 45-47c load so far.
 
well i think iam going to keep it as it is and just change the cpu as it will be nightmare as the case is rammed full off stuff and the tubes are braided lol ill put up some pictures when done :)

Finished butting it back together so thought i would put up some pic's ill be putting a build log for it soon aswell :)
Its based on an idustrial gun metal theme if any one was wondering why everything is tarnished :P








the funny thing is at idle it is running about 5 degrees hotter but on full load its about 4 degrees cooler ? any ideas why this is ?
 
I cant imagin doing on long tube runs though it is pain getting all teh tub inside of the braid then cutting them to size withteh comperssion fittings over the braid with out it freying into giant mess lol was worth trying it in the end :D
