Good Day All,

Currently I am setting up my first liquid cooled pc. I am not sure which route to go though. Should I go with a dual or single loop? Also which pump(s) to use in this build.

Cooling Equipment
Case: Phanteks Enthoo Primo
Radiators: Top- EK High Performance CoolStream 480 (38mm thick)
Bottom- EK Ultimate Performance CoolStream 480 XTX (64mm thick)
Case Fans: Air flow- Corsair Air Series AF140 Quiet Edition High Airflow x4
Radiator fans- Corsair Air Series SP120 High Performance Edition High Static Pressure x16 (push/pull)
CPU Water Block: EK Supreme LTX
GPU Water Blocks: EK ASUS GeForce 780 GTX DCII VGA x2

PC Components
CPU: i7-4770K
Motherboard: ASUS MAXIMUS VI FORMULA
GPUs: ASUS GTX780-DC2OC x2
Memory: 32GB G,Skill Ares Series DDR3 2133 (4x 8gb sticks)
Storage: Samsung 1 TB EVO SSD
PSU: CORSAIR RM Series RM1000 (with sleeved wiring kit)
Opt. Drive: LG Blu-ray burner

What reservoirs I use is depending on which route to take.

Thank you for your advice ! thumb.gif

Single loops are better. 1 MCP35x will do you fine in pumping this set up. Probably would be able to scrape by with a D5, it all depends on the restriction of the blocks you're going to be using. I personally prefer the DDC 3s over the D5s. DDC 1s kinda sucked though.

DDC1 are noisy and underpowered MCP-35x and MCP-35b for the win. I am a huge fan of PWM so the MCP-35x is usually the center of my builds. If you run 2 loops it will result in higher temps on the devices since you will always be wasting one side or the other.

1 radiator with those fans would give you very very low temperatures so 2 radiators with those fans will be even better.

I would highly recommend that you buy the PWM version of those fans wether you use them in PWM mode or not the flexibility is a must.

Also you should buy a phobya inline water temperature probe. There is a spot on your motherboard for plugging an external temperature probe and then controlling fan speeds based off of that probe. Running your fans off the water temperature is the ONLY way to go. You will also need to get PWM splitters... the swiftech ones are the best I recommend getting the sata plug ones instead of molex. You would need 2 of them for the 16 fans and you would also need a 2-way splitter.

Before buying the splitters though make sure that your motherboard can assign the temperature probe to a PWM fan channel... not all the 4pin headers are PWM... if it can not you will need to buy a little device that converts a normal 3pin voltage fan control into a PWM signal if you want to do PWM and use the motherboard as the fan controller.

The other option is running a Corsair Link or a Aquacomputer 5 or 6. The 5 only has 1 PWM output but that's usually fine. You should know though that in some cases running 16 fans can make a single PWM signal week. You can make a booster with specs from overclockers.com and you won't really know until you try running all 16 of the fans off the 1 PWM signal.

Hope that helps.
