Watercooling, need advice

post #1 of 16
Thread Starter 
Hi guys,

A couple of days ago I upgraded from a storm scout to a full tower stryke.

I have a little experience with watercooling, about 5 years ago with my Antec 900 I experimented with a TT Bigwater 945, it worked but it was a mess trying to fit that in a mid tower case.
Now I have a toolkit with everything I need, and a large case, I wanted to try watercooling again.

I have 2 x GTX 560Ti's in SLI and the stock cooler looks great, and I wanted to keep the look of it while being able to watercool them.

Here is a picture of how my cards look

Basically, I want to keep the stock coolers appearance with the additional cooling of a WC loop, to both cards.
This may mean that I have to cut away some of the plastic grill on the cards, which I am fine with.
I also want to cool my CPU in the same loop.


TL;DR~
Want to cool both cards and CPU without totally removing the GPU stock cooler.
Is this possible?
How much money should I expect to spend?
What size radiator(s) should I use?


Thanks in advance! thumb.gif


Here are some pictures of my setup, just for interest smile.gif

After looking at those pictures I took, I felt dirty and had to tidy up those cables tongue.gif
I also put the fans at the front because they look better, and to give the case better airflow.

You could try universal block like the Heatkiller GPU-X3 core:

I do not think that you will be able to keep the stock cooler on and water cool them and from my experience it is very hard to find a water block for the 560 ti's anyway.
With that setup, if you were to find water blocks for the 2 video cards, you would want 360mm of rad space minimum, the general rule of thumb is 1200mm rad for each water block, but just for a little head room you might want 480mm of rad space.
You are probably looking at spending between £300-£500 depending on what components you buy. If you do not water cool the GPU's the cost will be reduced by like £150 probably asgpu blocks are expensive.

I think you'd be able to pull it off by cutting off the shroud from the Stock cooler and using double sided tape or something to stick it to the water block? After that, you can cut off holes for tubing, etc to make it look cleaner. Though, this is just an idea because there's no other way to have both the stock hsf and a waterblock on at the same time .

You'd probably want at least 480mm in rad space because the rule is usually 120mm per component you want to cool and an additional 120mm just to be safe. For price, it really depends on what parts you plan to get as different manufacturers have different prices for their parts.

It absolutely depends how much cooling you want. I'm cooling a lightly overclocked i7 and a 660ti (same TDP as 560ti) with a single 120 rad. Temps are: 62-68C on CPU, 47-49C on GPU and 38C motherboard VRMs.

I am not much of an expert but I can tell you that you are pushing it a bit for those CPU temps. Max temp from intel is 67.4 c. I wouldn't go past 70 c.

From what I know most people like lots of rad so they can put more lower rpm and noise fans on them to have the same temps and a quieter system. A 240mm rad should be ok for you if you put some decent fans on it. 360mm or a 240 and 120 is good for future upgrades like better video cards and such.

What about ordering from aliexpress.com? It's a chinese website that sells cheap parts, and apparently a guy here ordered stuff from them and they were really good.

Also, where would I put the 240mm rad? At the top where the 200mm fan is located?

I don't want to do massive overclocks, I just want to make my PC quieter, the stock fans on the cards get very loud, and in the process get some experience with building and configuring a watercooling kit.

That max temp you're talking about is called TCaseMax and it's the maximum value of TCase, as measured by a thermocouple on the motherboard directly under the CPU die. You can see the value in your motherboard software e.g. Asus Probe II or with independent software like SpeedFan. You'll notice that value is much less than the temperatures of the CPU cores themselves. The TCase value is published by Intel in the thermal guidelines which are intended for OEMs to design their cases and cooling solutions to maximise lifespan of the chip. The motherboard measures this value and according to some calculations based on charts in Intel's guidelines it can set the speed of the CPU fan or case fans to keep the thermocouple below TCaseMax.

Here you can see my temps. Core temps here are 62-66C at full load, while TCase is only 49C, well below TCaseMax.



But as you said, it's about choice of how cool or quiet you want it. I'm just saying you don't need a 480 rad off the bat. Modern CPUs and GPUs are generating much less heat than when the "120 per block + 1" mantra was started.

Buy locally, then you're protected by European online sales laws. I've ordered from outside Europe plenty before, and it's great when things arrive in one piece, but returning broken items is so much easier and cheaper and quicker when the shop is nearby and when your rights as a consumer can be defended. So I now only buy outside Europe when parts are not otherwise available.

About placement of rads and fans: get a ruler and measure everything. Look online for parts you like the look of, find sizes and see if it will fit. Can make cardboard models to test fit before purchasing. If it's your first time, let go of the idea that you need to research which radiator will give you 1C better temps than another one. Just pick something that fits, looks nice, is modern design (e.g. copper fins on rad). Don't skimp on the pump though.

Thanks for your detailed reply.

Would the Heatkiller GPU block be good for future upgrades?
Any more parts recommendations?

To answer your questions
1) no you will need to remove the entire stock cooler from your GPU however you may be able to seperate the plastic shroud fro the actual cooler and stick that over your water block
2) I would say around $600 for a decent quality loop
3)You should use at least 360 mm of radiator space for 2 GPU's and a CPU, generally you should have 120mm for each component and an extra 120mm
