Opinions for a first time prospective WC loop

post #1 of 12
Thread Starter 
Hey there everyone,
I've read the forum for a while now (though I just created an account), & I have been throwing the idea around for a water cooling system for my rig (see below). I was just wondering a few things:

-With a Noctua NH-D14 how much cooler will a WC make my system?
-Should I get a block for my GTX 580?
-Is it worth it to spend the money on compression fittings?
-Preferred ID/OD on tubing? (I was thinking of going with 1/2")
-Based on my rig, what opinions do you guys tink about tube color(the inside of my rig is blue from cathodes so I was thinking blue uv or white or clear)

I was thinking about a few parts for it and possibly if anyone could throw me their opinions on them.

Pump: Swiftech MCP 655
Reservoir: Preferably a dual bay reservoir (XSPC?)
Radiator: Xspc rx360
CPU Water Block: EK Supreme HF Universal
Compression Fittings: Bitspower Matte Black Ultimate G 1/4 1/2" ID X 3/4" OD
Tubing: Primoflex Pro UV Blue 1/2" ID X 3/4" OD




I'm pretty excited about all of it as I've never water cooled before and it seems like something I can have some fun with. I'd love to hear everyone's opinions!!

Very much depends on what CPU you have and the temps you are getting at the moment. Generally Intel will drop 5-15°C on load over a decent air cooler. One other advantage is that you can crank your OC for less of a temperature rise compared to air.

On idle there will probably be very little difference, as idle temps are more dictated by your ambient temperatures than cooling method (ignoring active cooling)

Depends on your budget. If you can afford it then yes, most certainly. GPUs benefit more from WC'ing than CPUs, temperature drops of 30°C on load compared to the stock cooler are not uncommon. You also cut down on a lot of fan noise.

For anything other than looks, no. If installed correctly they are just as secure as barb + clamps and there is no performance difference.

Personal preference. I would always suggest going for the thicker walled variety as it is less prone to kinking. So that would make the choices:

1/2" x 3/4"
7/16" x 5/8"
3/8" x 5/8"

Post some pics and we can get a better idea. Also worth considering are anti-kink coils. These are plastic springs that you wrap round your tubing to help with tight corners, but can also be used for looks. For example I have clear tubing with blue coils.

Sounds good, looks like you have done your research.

If you choose to go with barbs remember to get some clamps, match the size to the OD of your tubing. You can also go with 7/16" tubing and 1/2" barbs - you need to heat the tubing to get it onto the barb but no clamps are required. Gives a nice clean look.

Throw in some kind of biocide like PT Nuke and grab some distilled water from a grocery store for coolant.

Oh sorry, I didn't have my rig sig set up right when I first posted, it's there now. I had a few pics of it posted on my rig's link, I'll have to take a few more pictures tonight when I get home so you can see my glow on the inside.

If I don't buy the compression fittings I'd be able to easily get a VGU block, I was thinking EK 580 GTX VGA Acetal block possibly?

Thanks for the input, I've been reading up a good bit about it (I wanna make sure. Don't screw something up haha)

If you do plan on using a 360 rad, your load temps could drop up to 15 degrees depending on the fans you put on it.

-Should I get a block for my GTX 580?
If you can afford it, go for it. Im using alphacool NexXxos blocks on my 580's. they are very well built and around $80 which is one of the cheapest i've seen for a full block. dont bother with universal blocks. Like John said, you can get very large temps drops. If you ever plan on going with sli then i highly recommend it
Quote:

Keep an eye on the marketplace. Sometimes you can get a really good price to make it worth it. Also, you could plan out your loop and use barbs where the fittings arent visible and compression where they are.
Quote:
-Preferred ID/OD on tubing? (I was thinking of going with 1/2")
Most people prefer that size tubing because it looks beefier. Not much real advantage/disadvantage do the different sizes
Quote:

Blue UV will probably look purple under UV light so keep that in mind. If you go clear avoid dyes they can gunk up blocks. I prefer white it looks really clean and makes the loop highly visible and easy to show off thumb.gif

You could get away with a cheaper pump. Check out the marketplace for BMavericks MCP 350's. They are brand new and sell for a great price. I have just one of those in my loop with my cpu, 2 580s underwater with a 360 rad and 240 rad and it runs it like a champ.

I like mine. easy to install, saves space, and if you get the one designed for your pump it will improve flow a bit.

Thats plenty for just the cpu.

One of the best imo.

Good luck and make sure you take lots of pics during your build! We love build logs and it will help if you run into a bump along the way and need advice. Take your time and plan ahead as much as you can. I always seem to do one really dumb thing everytime I upgrade. doh.gif Don't be like me.

What if I wanted to cool both the CPU and my card would I still only need a 360? Or would I be better off getting 2 240s or other sizes?

I think the white tubing is a good idea and something I'll probably end up doing (as well as the 1/2 compressions and 1/2 barbs to save money)

Would I also need multiple pumps or would I be okay with just 1?

I'm also going to be posting a few pictures of my rig when I get the time to, I haven't had time recently to snap a few and load them.

1 pump is plenty (MCP35x or D5 would be best). A 360 rad will cool a cpu and gpu just fine. Adding an additional 120/140 radiator later if you add another gpu would be a good idea though.

Okay, so did a little shopping, & I'm trying to compile a final list of things for this loop (tax money makes me happy lol)

-Also, if you recommend any other site than what I link my things from feel free to comment or recommend another part


Res / Pump Combo Reservoir

Pump

360RX Radiator

7/16 ID x 5/8 OD White Tubing

5/8 OD Anti-Kink Coil (Glossy Blue) x 2

EVGA 580 GTX VGA Waterblock

CPU i7 2600k Water Block

7/16 ID x 5/8 OD Compression Fittings x 6

1/2 ID Barbs x 6

PT Nuke

Please let me know if I'm forgetting something in this list!!

OH, also!

I'm really considering also doing a build log for this when I do it, any suggestions or links to guides for the best way to go about creating a build log?? Any advice would be appreciated!

Looks good. A few comments:

For the pump you can actually get a "pump only" model which does not have the housing. This is often a little cheaper and you don't end up buying the housing which you are not going to use anyway. I think Alphacool sell them as their VPP655.

For straight compression fittings there is little point in getting the rotary version. If you are going for an angled fitting then rotaries are very useful, as they allow you to rotate the fitting freely to the required position but it serves little purpose on the straight ones other than allowing you to screw the fitting in and out with the hose attached.

Finally it is worth shopping around the various stores to see what is cheaper where. Obviously you have to offset any savings against the extra delivery charges. When I am doing a big purchase like this I usually make a spreadsheet with all the things I need, prices from a few suppliers and try to work out the cheapest way. But then I do get very nerdy about the whole thing. Some other places to look are Performance PC's and Aquatuning US.


As for the build log, there is no real set format for them. Mostly people just post their plans in the OP followed by posts for updates along the way. If the thread runs long it is useful to put links to major stages in the OP.

Pictures are worth a lot, many people will scroll through looking at them without reading much of the text. Make sure to note any things that you found tricky, often this will help others who might want to do a similar build. Also, don't be afraid to ask for advice or opinions in a build log, often someone might have a great idea or a different way of doing things that you hadn't considered.

Have a read of some of the ones on here to get an idea, then decide how you want yours to look.

I am actually looking at a setup very similar to yours. In fact, it might be almost identical. FrozenCPU has a kit available for 300$, but it is not with the Supreme HF block, but it still includes fans and fittings... I am not sure what to do either. And yes, post pics! I will do the same when I finalize my build.
