I've seen some stunning custom loops in Parvum cases and its making me want to try it. I'm not sure if I should look at the D5 or the CM Eisberg block, but eventually, id be looking to WC my CPU and 2x 7970.

Budget is no more than £350-400, looking for black fittings and red coolant. Not looking to buy immediately, will be close to end of this year, but need recommendations. Will also need to start saving, this is what I've come up with so far, fittings...I'm unsure about which would suit.

YOUR BASKET
1 x Cooler Master Eisberg Prestige Jetstream CPU Liquid Cooler £89.99
2 x EK Water Blocks EK-FC7970/R9 280X CSQ £79.99 (£159.98)
2 x XSPC EX240 120mm Radiator - Black £37.99 (£75.98)
2 x Corsair Fan, SP120 PWM Low Noise High Pressure Fan 4 pin, Dual Pack (CO-9050012-WW) £25 (£50.00)
1 x EK-FC Bridge DUAL Serial CSQ Plexi £18.98
2 x Mayhems X1 UV Red Premixed Watercooling Fluid 1L £7.99 (£15.98)
3 x Primochill Primoflex Advanced Tubing 16/10 - Clear £5.99 (£17.97)
Total : £438.48 (includes shipping : £8.00).



Suggestions and recommendations are welcome :D
 
If you're on a budget, go for EK fittings with OD16 ID10 :)

But for a small mATX case like Parvum, you will need some more rotatory fittings, go for EK as well :)
 
My question would be is the Eisburg's pump capable of all that? Consider the pressure drop over the 2 gpu blocks, the cpu itself and the rads... Have a look over at martins liquid lab, that site really helped me.

I can personally recommend the D5, excellent pump.

+1

Doesn't look like it will provide a good flow rate and enough pressure :(
 
snips86x, look at my build log i have a water cooled parts list, you can get a idea from there, im in the process of getting my parts together at the moment.

It would seem that while the D5 is 750L/h at 400L/H, the Eisberg is still a great investment with plenty of oomph.

D5 is 1200lph
EK 4.0 is 800lph
EK 2.2 is 400lph

Remember though, these flow rates are for unhindered flow. Add blocks and radiators to the loop and the flow rates drop a fair amount. I am not even sure the eisburg pump has enough head to push it through a three block loop enough to keep temperatures acceptable with 120.4 rads keeping temps down. you may find the flow reduces to just a trickle when everything is set up. Replacing it with a EK supremacy, 4.0 EK pump and a reservoir would cost you about £30 extra but will give you a way better pump and block with a reservoir which is much easier to bleed and fill.

For a three block loop i would suggest the EK 4.0 pump, i doubt you want to rely on a pump like the Eisburg for a loop like this. They run pretty hot in single block loops due to the pump being on the block. Add in two more blocks which not only stress the pump but add a considerable amount of heat tot he loop which has fairly limited amount of radiator and you might find the pump giving out sooner rather than later.

The Eisburg also limits the CPU cooling performance as it performs similar to entry level blocks. Top end blocks dont cost all that much and perform considerably better.
 
i'm running a ek supremacy + ek 7990 block + ek xtx 240mm rad on a ek dcp 2.2 (lol ek fanboi much)
the dcp 2.2 doesn't have a problem pushing coolant through the loop

Do you know what the pressure is on that? I'm struggling to find any specs!
 
If i remember correctly the 2.2 has 2.2m of head and the 4.0 has 4.0m of head. An extra £10 makes a big difference here, the 4.0 will definitely be worth it over the 2.2 for the loop your planning.

They are named after the max head i believe.

*Edit* digging through my Wcing folder i found this:

I have a fair bit of experience with EK DCP pumps and can tell you that 5 high flow blocks is about the limit of a single EK 4.0 pump. My rig i am using currently has two 4.0 pumps but turned down a few notches on a fan controller and is running 5 blocks. If i switch one pump off and the other to full it gets a little warmer but 5 blocks ia a hell of a lot for a single £40 pump which requires no top!

yep, dcp 2.2 = 2.2m pressure.

it's a nice and small pump + res combo for small builds (like in my prodigy) cuz the res is mounted to the side unlike the d5/ddc
that being said, i'd have gotten something else if my case is bigger =)
 
Is having the 2.2 to a 2.6/4.0 really going to make that much of a difference? I don't want to spend more than I have too! 2 GPUs and a CPU is all that will be added to the loop.
 
It might be the difference between adequate flow and a trickle for a loop of three blocks.

The flowrates given are MAX flows unhindered. When you add components the flow drops depending on how much head pressure there is and proportional to the square of the max flow.

You might find it copes well enough with two blocks but doesn't cope at all with three. I have not heard of someone using the 2.2 in the sort of loop your suggesting. Pumps are not something you can skimp on, if they fail to adequately push water around the loop, your block will crack or the loop will burst at the tubes.

spec a recommendation?
 
Do what i said in your other thread, if funds are really that tight and you're having to skimp on the pump/block combo go second hand. you'll pick up a D5/Res + and decent CPU block for no more than what you'll be shelling out new on that (average....not good) pump/res/block combo.

In my Parvum i needed the D5 on the 4th dial for anything to pump through, spent all its time on the 5th setting. if your loop is somewhat restrictive that pump will not cut the mustard. Pumps can be reused, so the same rules on not skimping like in PSUs come into play :)
