Hi folks,

I'd like some advice please, I'm going to get a new case and would like to watercool the new CPU and GPU. The WC system I have at the moment is the XSPC Rasa 750 RS240 WaterCooling Kit which has worked well cooling the old CPU since I got it, however now its time to upgrade my old system which means upgrading the watercooling too.

New kit is as follows..

CPU: Intel I7 3770K
Mobo : Gigabyte GA Z77X - UD3H
GPU: EVGA GeForce GTX 680 FTW+ NVIDIA Graphics Card - 4GB with Backplate
SSD: Samsung 840 pro 256
HDD: 1x 1gb Sammy and 2x 500gb sammy
PSU: Corsair AX850
And enough Akasa Viper 120 fan's to start my own wind farm (from my older build).

Case: NZXT Switch 810 USB 3.0 Full Tower Case Gunmetal with Window (The window will be wasted on me as the left side of the case is against the wall plus I don't need fancy lights or disco fans).

The watercooling I've chosen so far is... And will it work together?

Phobya G-Changer V2 360mm Triple Radiator : G-Changer 360 V2 Full Copper
XSPC 7/16" ID - 5/8" OD (11-16mm) High Flex Tubing : Clear
1/4" Thread Barb Fitting for 1/2" ID (13mm) Tubing : Silver
EK-FC680 GTX FTW - Nickel [3831109857014]

Now this is where I'm getting myself confused, a little too much info overload as it were, from reading too many posts ;).

Can I use the XSPC Rasa CPU block that I already have? If not, could you please give me some recommendations on what pump/res to use.

Will the res/pump combo that came with my original kit be enough to cool both CPU and GPU or will I need to get a newer/better one?

Will the XSPC RS 240 rad be ok to use in the bottom of the case along with the Phobia rad in the top, or will I need to get a newer/better 240 rad?


Many thanks for your time in reading and replying to this post.
 
yes you can use the CPU block, and yes the RS240 rad is a decent rad, a 240 + 360 will be be fine for CPU + GPU loop

pump however, I would change to either an EK DCP4.0, Laing DDC or Laing D5, you can also choose a new res to suit

think about fan directions though - for best results you want all the Radiator fans to either be sucking air in to the case or (my preference) is to have them all on exhaust, with any other fan locations you can on intake - this gets all the heat out of the case as quickly as possible

if you have one rad on intake and the other on exhaust then it means you are sucking hot air in to the case and then blowing it over the 2nd rad, which massively reduces it's efficiency
 
Thanks for the reply, and I'll check out those pumps and a new res, tube I think :D.

I did have an idea on the airflow, I was going to have the small 240 rad on intake from the bottom and a 140 at the front on intake, the 360 on exhaust at the top along with a 140 exhaust at the rear.
 
worst possible combo

put both the non-radiator fans on intake and the 2 sets of rad fans on exhaust, or vice versa, going half and half will mean you have hot radiator air being blown over the 2nd rad, massively reducing it's capability to cool

water cooling is not the same as air cooling, where you put all down/front fans on intake and all top rear fans on exhaust, by adding a radiator to the down fans you are adding a source of heat that isn't there in an air cooled rig

you could try creating a baffle and have the bottom rad on intake, with front fan on exhaust, and then the top rear fan on intake and the top radiator on exhaust, but it's a lot of extra work
