Just put my loop together, looking at the instuructions is shows hot water from cpu block going to res and then pumped to the rad. Would it not be better having the hot water go stright to the rad then res? This way there will be less condensation in the res as its holding cooled water.
question for experienced watercoolers
- Thread starter red eye
- Start date
The water temp of the loop will even out. you might get a difference of 1 or 2 degree between different points. but remember the water is flowing/being pumped around.
So long as the pump comes after the Res you will be fine. Use the best route available for the tubing.
=== RES == PUMP == RAD == CPU ==
Is just as good as
== RES == PUMP == CPU == RAD ==
It is very unlikely you will get condensation in a house at room temp unless you are chiller of some description.

There is a school of thought that always places the CPU cooler after the pump as that gives maximum pressure at the CPU cooler. This can be important where the CPU block is jetted or uses a slotted plate.
Every time you put a component in the loop it reduces pressure at that point. So if your blocks need high pressure, put them early in the loop after the pump.

Really? My understanding is that most modern CPU blocks are jetted and therefore work optimally with the highest pressure. It might only be 0.5C, but why wouldn't you do it if there was even a tiny possibility it might work better?
I mean that most pumps are powerful enough these days do that it doesn't really matter
I'd rather go for neater tubing over 0.5 degrees

They've got the same pumps they always had, surely? Pumps like the Laing D5 have been around for ever and the DDC dates back to the first water-cooled Mac. All the other pumps are variations on the same aquarium pumps we had back in 2000. I'm actually waiting on someone to bring out something genuinely novel.
As for looks over performance, if you're looking at it, you're not using it. I use mine 100% flat out all the time. I'm waiting on the mainstream backlash when folks realise that all the bling-bling stuff really messes up your expensive gear if you use it for more time than they recommend.
Sorry, i'm really not explaining myself!
What i meant to say is that due to even the cheapest pumps being powerful enough to drive a basic loop, for the sake of a degree or two, most would prefer to have a better looking system.
BasicaLLY, IT COMES down to looks over performance

anyone buying watercooling for looks over performance should stick to air cooling
watercooling is for performance or for noise, altho the difference is small it is always better to go pump cpu rad res on a simple cpu loop
I do it for noise and good looks. performance, as long as it's better than air, i'm happy
Basically it is a case of yes the temps will be very slightly lower but there certainly isn't a problem running the loop in a different order. It isn't all looks though, it can be whatever is easier as I know with my set up it would make the tubing take a right PITA route round the case.
I just installed as instructions, I was planing to swap the tubes to the pump and res around to test but you have already done the teasting. Any way I'm done leak testing my intsall just got to plug mobo and gpu then I can see the temp difference
It's not pressure, it's pressure drop, it doesn't matter where you place the CPU block in a loop as the drop across it will be the same regardless. Think of it as the various blocks being resistors and the pressure drop being voltage.
I've just double checked and the pressure will be greatest after the pump. For it to work as you describe you would need an airtight, sealed, system that was pressurised by the pump. That would indeed have the same pressure throughout.
But as in most loops you have no pressure in the reservoir the pump generates the pressure and that is then lost/reduced as it passes through each component in the loop.
If you think about it, the water in the reservoir doesn't try to force it's way out past the pump other than by the pressure generated by mavity.

Yes, pressure is greatest after the pump, it's also at it's lowest before the pump. If you have a 1 bar pump and place a block that takes a 0.5bar drop across it immediately after it, the other 0.5 bar is dropped by the other compenents. If you then put the block before the pump, it still takes a 0.5 bar drop.
Water is imcompressible, the actual pressure doesn't make any difference.

Yes, but just like your current example flow rate = pressure x volume. If we agree that water is incompressible then the volume remains the same and higheR pressure means greater flow rate. As you have already stated there is a pressure drop across each component in the loop therefore the sooner after the pump, the better if I want a high flow rate (which I do in a CPU block). Does that make sense?
Flow rate is the same around a loop though, based on the pumps performance and the total restrictiveness of the loop. The actual order of the loop components doesn't affect the overal restrictiveness, with the exception of putting things in parallel to reduce restrictiveness.
