Better to cool the GPU and CPU in line or independantly ?

Hi all, I'm planning (what I hope) will be a fairly straightforward watercooling loop to cool 1 GPU and 1 CPU with 3 main aims -

1) Lower "standard" temperatures for high end gaming graphics (not planning on any overclocking for the time being)
2)Quiet running
3)Must look tasty (building inside an NZXT switch 810 case with UV lighting)

I'm pretty happy with 90% of the general do's and don'ts but there's just one thing I'm not sure about. I've seen quite a few setups that have just one loop going RES/PUMP > GPU > CPU > RAD > RES/PUMP

But this means your delivering already warmed fluid from the GPU onto the CPU and I'm assuming that cooler fluid can take on more heat than warmer fluid ?

Would it therefore be better to have two lines (feeding into 1 RAD )

Line 1 - RES/PUMP > GPU > RAD
Line 2 - RES/PUMP > CPU > RAD
Line 3 - RAD > RES/PUMP

Any advice would be much appreciated :)
 
Sry, should have put all this up at the start, schoolboy error....

Pump - XSPC Photon D5 170 resevoir & pump combo
Rad - Alphacool NexXxos UT 60 dual 120mm

Just out at the moment will have a look when I get home I'll look your case up


Gotta love that combo
D5 is boss

U should be able to get a 360 in there

It would fit, you're right but I'm really keen to use acrylic solid tubing and a 360 would squeeze the rad inlets / outlets right up against the edge of the case (unless I get funky with a hacksaw and Dremmel :eek: )

The joys of having a 900D (Got 2x 480, 2x 240, 1x 120) in mine

The UT60 is a very thick radiator (e.g. 85mm with fans attached), however it's got some great connection options due to it's multi-port design

OMG radiator city...

The multiport is exactly why I've gone for it - inlet on the left end of the rad from the gpu and cpu, then the outlet on the right end straight down to the pump/resevoir - should be able to have a tidy arrangement for the pipework. Aiming to mount the rad inside the top of the case and the "pull" fans above it to minimise visible bulk
 
Case is black (matt) but white components show up lovely under the UV, having a total rethink now lol, ok going for a 360 but not xflow, inlet and outlet on the left, tubing and lovely shiny compression joints will be in the bottom and left side of the window
 
K, gone for a Black Ice Nemesis 360 GTX, arrived today, looks like will be a nice fit without intruding into the case too much. Also took delivery of some UV stuff today - acrylic Primochill UV blue tubing and XSPC UV/clear flexi tubing - Unbelievable difference between the two, the acrylic is very, very weak UV reactive and totally see through under UV light (with no coolant ) whereas the XSPC is INTENSE, very opaque glowing blue, I guess due to the thicker walls. Have a dilemma now. I was going to watercool with the acrylic as I wanted nice straight lines but the flex tube looks infinitely better and has a larger internal diameter so better flow.... hmmm
