The Neophyte's Custom Liquid Cooling Guide: How To, Why To, What To Expect
by Dustin Sklavos on September 30, 2013 12:01 AM ESTFor my build, I ran into a series of small but notable issues that made me question whether I'd made the right decision in opting to use the Corsair Carbide Air 540, specifically in terms of clearance. I opted to use the two in-line quick-release connects on the radiators; I'd connect an arbitrary amount of tubing to one of the ports on the radiator and then put half of one of the connects on the other end of the tube before routing that tube back behind the motherboard tray. This made assembly much easier as I didn't have to install the pump and reservoir early on or measure out the length of tubing I'd need; I'd just affix the appropriate amount of tubing along with the other half of the quick-release to the reservoir and pump.
My first major problem child was the 360mm radiator in the front. Originally I'd wanted the fans on the outside in a push configuration instead of pull, but you can see clearance around one of the two 3.5" drive trays wound up being extremely cramped. There's stress being put on that joint (as well as a bit on the connector that's routed back behind the motherboard tray), and I was concerned it would be likely to leak when I primed the system.
The other issue was routing the lines from the pump and reservoir. Because the power supply is so deep, and because power cabling naturally wanted to be in the same cubby area, real estate was at quite a premium. Before installing the pump I had to disconnect all of the modular power cables from the power supply just to get some breathing room.
You can see I also wound up using especially long lines from the pump in order to prevent any serious kinking, and this is all before the power cables wound up getting threaded back in.

I'm about to nerd out so forgive me...
Some of the conclusions from this article aren't representative of what you can truly do with water cooling but rather the limitations of the equipment you selected.
For starters, the addition of a pump doesn't automatically mean more noise. The pump you selected can sound like an angry wind up toy and it generates a lot of heat and vibration. A Laing D5 Vario/MCP 655 pump is whisper quiet, especially with a Koolance PMP450 top on it. It can be running at full speed pushing 4.6 liters per minute through the system and so long as it's decoupled properly from any hard surface in the computer case then you wouldn't be able to hear it if it was 6 inches from your ear.
I run a 3930k overclocked typically to 4.4 GHz although I've done higher and if I'm running prime 95 or Intel burn-test my temps are about 66C TOTAL and not 66 DELTA?! If your room is a comfortable 24 C does that mean your CPU temps are 84C on water? Something isn't right. I don't know that chip but maybe it needs to be Delidded and Lapped. I had that same Apogee HD block before on a 3930k which is a much hotter chip and my temps never reached that high.
The fans you are using have a familiar style... because they look just like the Scythe Gentle Typhoons which have the best noise/static pressure of any radiator fan I've seen tested. If you used Gentle Typhoons, temps would be lower and the whole thing would be quiet.
The coolant you used is probably less efficient than distilled water. The only coolant I've used that delivers lower temperatures is Ice Dragon which is heavy and expensive and cuts your flow rate in half. Distilled water works great and it's $1
I can't tell for sure but it looks like small diameter tubing was used. Using 1/2" inner diameter tubing delivers higher flow which means lower temperatures.
Those radiators are anorexic. I don't think they come much thinner than that. Use something with a bit of heft. My rad is 80mm thick which is twice the thickness of those Swiffys. This allows for substantially more cooling and also higher flow rate which, again, increases cooling and lowers noise.
My 3930k + my GTX 690 dual GPU card can both be overclocked and Folding or benching with all cores/gpus at 100% and it can be silent enough that if it weren't for the power light, you wouldn't know it was on. I briefly used air on my GTX 690 and it sounded like a hair dryer and filled the room with the scent of charred air much like the smell of turning your heater on for the first time in winter.
If anybody reads this, you can expect better results if you buy better components. I started off with Swiftech because they were cheap and also they were carried at my local MicroCenter. I quickly graduated to better parts. The Apogee HD is an excellent water block and the Swiftech MCP35X2 and MCP655 pumps are both excellent pumps (but neither were used here).

Why did you only post OC Liquid benchmarks? I'm interested in Non-OC liquid numbers. I have no interest in overclocking, I just want the quietest, most efficient system.mc2k4 - Tuesday, December 31, 2013 - link
Terrible article, would put off anyone from watercooling. Those results are horrendous.woogitboogity - Wednesday, January 22, 2014 - link
I did a custom build CPU/Northbridge/GPU with the cooling loop going outside the case to the reservoir about 5 years ago...I will admit that when the thing ACTUALLY worked for a while it was insane... granted it was 5 years ago but even then seeing lukewarm temperatures on essentially every component at full load was pretty impressive.
BUT... I feel that one thing missing from this article is a reality check: I work in experimental physics and I have had to work water cooling and even liquid helium cooling for magnets. 5 years ago the vendors of water cooling hardware implied a LOT more than they could back up in practice... since then their claims have only gotten more extravagant. At least in the days when people did water cooling from scratch they did not have marketeers offering false assurances in the form of warranties that clearly do not cover damage due to other hardware.
BOTTOM LINE: I think the subtext of this entire article that needs to be clear is that custom water cooling should be treated as a VERY expensive hobby. Expect to lose every component... period. If that is not an acceptable outcome don't do it. I say this because I deal with experimental cooling all the time and I got burned by the sub-par cooling hardware offered not too long ago (same hoses and cooling block designs... still using water).

Just do yourself a favor. STAY AWAY from this company. Yes they look good. But when it breaks and it WILL. All they do is give you the run around. They have had my system for over 2 months trying to fix the garbage they sell. Worse company out there for support. DONT BUYalpha3031 - Sunday, June 22, 2014 - link
What about these new Devils Canyon chips?
