Hi folks I am going to be watercooling my computer very soon however first I would like to get peoples feed back on my loop before I plunge into buying it as it is alot of money. I have tried to make this as detailed as possible but ask away if you have any questions

My main questions that I would like answered are :
Is my powersupply good enough to run my loop and my pc ?
Will the GPU blocks I have chosen fit my GPU's and will I need to passive cool the ram at all ?
Will it generally work or can anything be improved ?

I have numbered the parts in the diagram to give you a better look at my logic.

PC Components:
CPU - Haswell i7 core ( part 3 )
GPU - Crossfire Gigabye windforce 280x's ( Parts 4 and 5 )
Case - Corsair C70
PSU - SuperFlower Leadex GOLD 850W

Watercooling choices:
Pump/resovior combo - EK Water Blocks EK-BAY RES incl. Dual Serial PWM DDC 3.2 Pumps
240MM radiator - Black Ice Nemesis GTX 240 Radiator
120MM Radiator - Black Ice Nemesis Radiator GTS 120 XFlow
CPU Block - EK Water Blocks EK-Supremacy Clean CSQ - Gold
GPU Block - EK Water Blocks EK-FC7970 CSQ

The way I would set up my loop is :

Any and every information would be fantastic folks! Thank you!

Your power supply is fine.

If your gigabyte cards have the stock pcb, then yes they will work. I believe they are but you can ask gigabyte themselves to make sure.

Get the reservoir and D5 pump combo instead of the dcc. You also only need a single D5 pump. The reason behind the d5 is that they are more reliable and quieter than ddc's.

I personally would get higher fpi radiators (specifically the 120mm rad). This is simply from a performance standpoint since you are using two GPU's and a CPU.

What part is number 6?

Dual DDC's would be better than a single D5. I ran a loop very similar to that setup on a single D5.

If 6 is your pump and 1 is your reservoir, you should consider reversing that. If 1 is your pump and 6 is your reservoir, you should consider elevating or changing so that your pump doesn't ever intake air.

your pump should always get water from te reservoir not the other way around.

I advise you to do this: Reservoir -> pump -> gpu1 -> gpu2 -> 240mm rad -> CPU -> 120mm rad
And I recommend you to use push pull on both rads ( 6fans )

Push pull won't help him on such low fpi and not so thick radiators.

I disagree. Push/Pull is almost always a benefit on any radiator thickness/FPI, although diminished on thinner/lower FPI when you could use a single, good fan. The 240 rad is 54mm thick, according to the very-slow-loading HardwareLabs page. 16 FPI is also fairly medium-density when it comes to rad fins.

Although, not certain why an X-flow rad vs. a dual-pass 120.

Fair enough. I just personally wouldn't spend an extra $45-60 for a maybe 4 degree difference.

As long as you have good radiator fans, you temperature difference won't be that great. Push pull does help when you use fans that don't perform so well on a radiator. That is why push pull was really popular when people would just throw some cheap yateloon fans on. The temperatures difference was larger than it would be if you used something like Noctua NF-F12's on a radiator.

But really it all depends on what you want to buy and how much you are willing to spend to get those few degrees less.

Airflow over your rads makes a big difference towards your delta-T. If you aren't flowing many CFM's of ambient air over the above-ambient rad tubes/fins, you are slowing the exchange rate at which heat in watts is being removed from the system.

Three biggest performance indicators of a loop:

1. Flow rate in LPH/GPH - moving warm water to the radiator as quickly as possible
2. Surface area of radiators - how much water can make contact with the heat exchangers at any given second
3. Flow of ambient air over the warmer radiators - more flow removes more heat in watts per second/minute/hour

All the above are assuming you have good block contact with the heat producing components in your loop (GPU/CPU, etc).

push/pull will help lowering noise and get down temps. but if you are going to over clock your cpu and gpu's I dont think you have enough rads any way. you r looking at around 150watt for the cpu and 300watt for each gpu so you will need to cool 750watt
