Need some helpful advice on my WC purchase

Need some helpful advice on my WC purchase
I am currently planning on using 1/2-ID and 3/4-OD for my tubing. I will be using at least one QDC ( Koolance I think is the only game in town for this ), and I do plan on using compression fittings, as they look awesome, with these more then likely to be BitsPower, along with a few 45s and 90s also from BitsPower. My build is going to use the Silverstone FT-02, and I have seen some pretty awesome setups using this case, and the 90 degree motherboard mounting is just sweet. Lvl8Hacker's build was what really sold me on going WC, as I had already picked out the case but was amazed how well it all fit inside. Below is the current list of non-watercooling parts that are going into this build:

  • Intel i7 2600K Retail CPU
  • Asus Maximus IV Extreme-Z Motherboard
  • Silverstone FT-02 Case ( Black / Window )
  • Corsair Professional Series Gold AX1200 PSU
  • 2x EVGA GTX 680 Hydro Copper (SLI)
  • Intel SSD 520 240GB Retail
  • Corsair Dominator GT 16GB (4 x 4GB) DDR3 2133

In regards to my watercooling equipment, I am down to a few choices on a number of parts, though it has been hard as hell to choose, so I wanted to fly some of these choice by everyone, and get any input I can.

Cpu Waterblock:
I am down to what seems like 2 choices, each has had great reviews written about them, though none of these seem to be an easy pick, though I am currently leaning towards the Swiftech Apogee HD due to the ease of mounting and the extra ports for more complicated setups.

Swiftech Apogee HD:
I find that other reviews seem to give similar results and opinions on the Swiftech Apogee HD, though most seem to think that it's mounting is very well handled. Martinsliquidlab seemed to REALLY like this block, especially in concern to mounting, and at $69.99 it doesn't break the bank.
Here are some good reviews:

XSPC RayStorm:
I find that most other reviews give this block very high marks, though some make comment on some questionable mounting ( loose and hard to determine correct pressure ). Again Martinsliquidlab seemed to REALLY like this block, and at $49.99 this thing is a steal ( for the acrylic one, $99 for the copper version )
Here are some good reviews:


Radiator:
After seeing Lvl8Hacker's Silverstone FT-02 build on this forum I realized that I could do WC in my chosen case. As I want to use the Silverstone FT-02 case in my build, I haven't found any other radiators that fit the bottom like Magicool Extreme 180MM line. I also have the option to use the Double version instead, which shares the same dimentions but only 2/3 the length. I am unclear how big of a radiator I really need, so perhaps the Double is enough, perhaps not.

Magicool Extreme Triple 180mm x 35mm Slim Radiator:
I was first turned onto this radiator when I saw Lvl8Hacker's build on this forum, and as I was planning on using the Silverstone FT-02, I figured this was a pretty easy choice. I do have to mod the drive cage like Lvl8Hacker did, which I don't think is a huge problem. My only pause in choosing this radiator is a complete lack of reviews on it.

Magicool Extreme Double 180mm x 35mm Slim Radiator:
If I chose to not mod my drive bay as Lvl8Hacker did in his build, I could go with this radiator, though I do have a few concerns. My primary concern with the Double version is that it may not handle the heat that my i7 2600K overclocked to 4.6 ~ 4.8Ghz will produce in addition to my dual GTX 680 Hydro Copper units will be adding into the mix. I also do not want to run the 180mm fans at some insane rate to make up for choosing to go with the Double version of this radiator. Another concern that I share with the Triple version is that I haven't found any reviews on it.


Pump:
Now we start into the area that I have the least understanding in, the pump. I have seen rigs with single and dual pumps, and all sorts of pump models. As I think my flow is pretty simple ( Res > Pump > Radiator > CPU > GPU 1 > GPU 2 > Res ), I am unsure which pump to get. I have listed a few that I have read about, though I would love to hear any thoughts anyone had.
TBC...

You seem to be picking components by how they will look and how they will fit.

Determine how much heat your system will generate.
Determine which blocks will remove that amount of heat and the flow rate they require to do so.
Determine which rad will remove that amount of heat and the flow rate it requires.
Pick a pump that will deliver the flow rates required above.

A great place to start would be Skinnee labs (skinneelabs.com).

As for bits power fittings, I have always found them to be rather restrictive compared to plain old barbed fittings (with a true 1/2" I'd).

If you follow the above procedure you'll know how your WCing will perform before you spend any money. Anything else is just believing othe people's opinions (though they may be informed opinions).

How do you determine these numbers? I know that skinnee labs has the numbers but how do you tie in those numbers from the pump flow rate to say the cpu block.

What is the average or best flow rate you want to achieve in your system?
post #4 of 7
Skinnee's test results will list the resistance of blocks and rads at various flow rates along with their effieiency (how much heat they will remove at those flow rates).
You choose the flow rates you need to remove the heat you have and read the resistance of the blocks and rad at that flow rate.
Then you add up the flow resistances of the blocks and rad along with theresistance of the tubing and fittings then choose a pump (from skinnee;s pump tests) that will deliver that flow rate you need into your calculated resistance.

There are also many other places to get performance date. And if a manufcacturer doesn't provide them, or that aren't easy to find, I would think twice about using their product!

So then using this MCP35X pump for example http://skinneelabs.com/swiftech-mcp35x/2/

With the chart on the second page it running at 70-100% speed, is it saying that with my loop built, if the flow rate of 1.00 GPM I will get 6.13 PSI of head pressure?

Or should I be really saying to myself that I want a target of 1.50 GPM flow rate in my system, to get 1.50 GPM with the MCP35X @ 70-100% speed, it can only handle 6.13 PSI there for I have to make sure the blocks/rad/res/tubes used need to be less than 6.13 to obtain the 1.50 flow rate?

And to be able to get the PSI on the blocks/rad/tubes I need to look at what their PSI rating is at a flow rate of 1.5 GPM? How do I control the flow rate? Or obtain the GPM I want?

Sorry if I'm confusing you, this is quite confusing to me.

So for example, I think I'm getting this.

If I want to have a 1.50 GPM flow rate and I use

XSPC Raystorm CPU block @ 1.50 GPM it rates 1.14 PSI (http://martinsliquidlab.org/2011/09/26/i7-2600k-cpu-xspc-raystorm/5/)
BI GTX 240 rates 1.2 PSI (based of this article http://www.overclock.net/t/1108918/what-can-my-pump-handle-a-guide)
BI GT Stealth 120 rates 1.2 PSI
Fittings (these connect the tubes together?) .3 PSI
Tubing 1.0 PSI (6.6 feet of tubeing)

That would give me a total of 5.2 PSI approx. on my system.
Which means that if I go with the Swifttech MCP35X I will get a flow rate of 2.00 GPM running 50% or 2.25 GPM running at 70-100%? (based on http://skinneelabs.com/swiftech-mcp35x/2/)

Is this correct? Am I doing this right?

Is 2.00 GPM high? I do want to add a full GPU block to my Nvidia 680 when it comes out so I want to be prepared for the additional resistance right?

Your calcs and assumptions are correct.
Don't forget to add in the heat from the pump.
