Single loop ($500), a few Q's...

post #1 of 22
Thread Starter 
EDIT (NEW questions):

I've been looking at WC for awhile now (actually part of what got me interested in building my first system a few months ago) and ive finally saved enough up (lol), to get a loop going.

First, components (cpu only)
i7 920 @ 4.0 (1.248vCore)
Cosmos S

Thirdly my "proposed" water parts are
Black Ice GTX 360
DDC 3.2 (w/ EK rev.2 top)
EK supreme HF
san ace 9G1212E1011 (118CFM, 3100rpm) x3
EK 250 multioption res
FC-5 30w (newer rev. the one that doesent make noises)
primoflex + bitspower barbs

So, questions.
EDIT:

1. if i ran 3 of those san aces on one channel, daisy chaining them toghether, would the drop in current affect the watts each one is getting so they would actuallly run slower then rated at 12v? would i need to put it higher than 12v to get their rated performance?

2. Also are there any alternatives to PT nuke? and ive heard with primoflex tubing + distilled you dont even need PT nuke?

Thank you!

1.) Get the 3.25, it's an updated version of the 3.2
2.) No idea
3.) You didn't even try to look, the D5 (655) has more GPH than the DDC 3.25 (355), but the 355 has a higher head pressure than the 655 making it ideal for high restriction loops.

is the 3.25 improved enough to warrant a 25$ price premium? or should i just stick with the 3.2..

Paying an extra $25 is way too much, it's like, $8 extra on DangerDen.

I'd say skip the GTX360 and delta's and go with a quieter loop. SR360, XSPC 360, thermochill PA120.3, etc. Something for low speed fans. Throw on some Gentle Typhoon 1850 RPM fans w/ shrouds and put them on a fan controller.

I've got my CPU + Motherboard + 5870 on my XSPC 360mm radiator with my gentle typhoons running @ 1200RPM. It's quiet and more that sufficient for gaming and such. If I'm going to be folding 24/7, I just turn the fans up to ~1650RPM and let it do it's thing. 150+ cfm 38mm fans are for benching and stress testing, I'd never consider them for daily use.

Just my .02

actually the 3.2 is $65 or $70 on sidewinder computers and the 3.25 is 90. but your right regular price it is 8$ more.

and a (noobish) question about fan controllers, if were to hook up two or three fans to a single channel like a lot of people do, how would each fan get the right amount of volts? and if i was using the fc-5 with the LCD readout which fan would it tell me the rpm of?

and thanks for the help.

What this is called is daisy chaining. When you connect stuff in parallel in a circuit, the voltage stays the same along all branches, while it's the current that is divided. If you were to connect them in series- which is hard, and you'd really have to be determined to do that- you would be dividing the voltage, while the current would stay the same along all branches. When you're connecting all the molex connectors together in the back to the psu, you're doing it in parallel, thus the current is divided from that rail on the psu to all the various components, while the voltage remains the same.

When you are daisy chaining fans, make sure to check the power consumption on each fan, and add up the total power consumed by all the fans on the chain. This is because each channel on a fan controller is only rated to a certain power consumption, and after that you will probably blow that channel on the fan controller. I've learned from experience 8 gentle typhoons on one channel was not meant to be...

LOL! thanks for the info on the fan controller, im good for voltages, but whats the current do? if im running 3 fans at 12v on one channel what affects will the drop in current have?

If you have $500 and want to do a killer single loop, consider these parts:

Black Ice SR-1 360 - newer variant of the GTX radiators, that offer much better performance with low-speed fans... even with high-speed fans, it should offer better performance than the GTX

DDC-3.25 w/ EK or Bitspower top OR D5 w/ EK or Bitspower top, both will give you great performance (I'm personally a fan of the D5 as it runs cooler, and seems to be more reliable in terms of 24/7 performance)

EK Supreme HF = winner... stick with that, pick whatever flavor interests you, but make sure you use the #1 jet plate for best performance

EK reservoirs - they look nice, but I've seen issues where they have cracked over time, but for the most part they're sturdy, and won't crack as long as you take care of it and use the right fluid

fan controller... use whatever you want as long as its not a PWM controller

fans... one of those deltas will make you go deaf... three or more of them will make you want to kill yourself shortly before you go deaf... consider some quiet fans that push 50-75cfm for the SR-1 radiator, and for a CPU loop, will give you straight up kick-ass performance


with those parts, you'll have headroom for adding a GPU block to the loop and still be able to keep your temps to a minimum
