watercooling first-timer

post #1 of 19
Thread Starter 
hi all, this is the first time i will set up a water cooling system and i just want to make sure what pump to use for the amount of tubing shown in my little animation:
http://media.putfile.com/water-cooling-idea
(ignore the fact that there are two rads in the front. just pretend there is one as i never new there were thicker ones)
how do you determine the flow rate required in a pump for a certain amount of tubing, blocks, rads, and head? btw, my case is the RAIDMAX SMILODON

also i am confused about what liquids to use. all i know is it takes 90% distilled water and 10% something else. anti-freeze/corrosion?

MCP355 or a MCP655

Heres the smaller one...strong head though.
Attachment 50877
its not adjustable, but is more than adequate for 1-2 blocks and a good size radiator. You can find it
here
Heres the bigger one..its adjustable and features many possible upgrades, like a brass top for stronger head pressure, or even a AC conversion motor to run AC instead of DC.
Attachment 50878
You can find it here


Either one would be fine...though most would recommend the 2nd.

Here is some good reading for you...As far as pumps go the D-5 is up to the task of a normal loop CPU and a GPU or 2..The 18W DDC will overcome more restriction with its higher head...The best performance is with the RD 30 Iwaki run at 18V or dual in-line 18W DDC's with Petra tops..The new blue impeller DDC's performance sucks though and thats about all you can buy new now..The old orange impeller pumps are great....



Good stuff to read....

You can determine your flow rate if you can figure out your systems pressure curve, and plot that on top of the pump P/Q curve. Where the system pressure curve intersects the pumps P/Q curve would tell you how much flow rate you can expect. I'm talking about the P5 line that slopes down from left to right. Your system pressure curve will curve upwards because as flow increases the parts in your system create more pressure drop.

Bottom line is most of the 2-3 block plus rad setups will work just fine with either of the two noted above.
Cathar from XS knows this stuff like the back of his hand, I'm trying to play around with building my own flow rate estimation spreadsheet to see if I can predict it as well.

Most loops end up with somewhere between 1 to 2 gallons per minute and the thermal properties curve of most water blocks are flat enough that it doesn't make a HUGE difference.

Anyhow if I get a flow estimator spreadsheet done, I'll be sure to share with everyone just as a fun tool to play with.

how does a wc overclocked Q6600 compete with a stock QX6700? i'm beginning to rethink this whole watercooling thing

Well, I havent tested my Q6600 out yet..I will be powering it up today though. But I can tell you that my e6700 [2.66ghz stock] OC'd to 4.0ghz is just 800 MIPS/MFLOPS behind a Q6400, according to SiSandra XI. Thats a 2.6 core duo, just about equaling the performance of a 2.0ghz Quad core.

So, more to answer your Q-> the Q6600 can easily achieve speeds around 3.4-3.6ghz on air cooling, when paired with a new P35 board. Thats almost 1ghz above the QX6700 at stock. With good cooling, [TEC, Phase..etc..] you could shoot for 4+ghz with the Q6600....and the new steppings [G0] are soon to be released, dropping the power consumption from 105W -> 95W.

Your making me want a quad.......

Thread Jack!
Ira- the new 45nm Q's should be between 65W-95W for power consumption, all with 8-12mbs of cache, using a 1333mhz FSB.

Check the WR's for the CpuZ site...all of the highest FSB speeds and DDR speeds are using the new P35 chipsets and DDR3. Hows 600mhz FSB, 3.6ghz Q4 and DDR3 @ 1.8ghz sound too you...?

so i can wc OC a Q6600 and blow past a QX6700?
for my loop, i dont think i will wc the gfx. i'll just save some money and get some passive air cooling on it since im not OC'n it.

edit: so will the prices on the current quads lower or will the 45nm's be the lower-priced ones and the old ones off the shelves?

what rad will work best for the above video:
-Double Heater Core with Fittings
-Black Ice Pro III Radiator
-Black Ice XtremeII Radiator
-Black Ice XtremeIII Radiator
-Stealth GTS 360 Black Ice

I'd go for the GTS with some decent cfm fans and a shroud....If you don't mind higher cfm 100+ the BIX or heater-core would be fine also...



Hey CL -That sounds freaking sweet......I'm setting up a 437W Pelt rig right now should be done by the end of Summer then I might have to jump on one of those....
