I'm going to rebuilt my 'babies first watercooling' setup I did a while ago and add some common sense stuff like drain valves. Also thought I'd add my gtx 1070 into the loop while I was at it because the fans are noisy af. So some novice questions: 1) is a 240mm by ~50mm deep copper radiator enough to safely cool CPU and GPU? It's got a couple of 120mm fans on it, and the components only have light overclocks (25-50% or so) 2) any better bit of software for managing fan speeds vs temp than speedfan? It's ok, but is kind of binary. 'Under target temp, drop to min rpm' or 'slightly above, 100% FULL SPEED AHEAD BRRRUUUM'. Ideally something I can design a curve for would be good.

Also the more radiator space the lower you can run your fans. For fan control I recommend an aquaero. The baller ones with screen are about $160 but you can get one without a display for $70-$100. It's a standalone computer that can run a pump and fans. You can hook multiple temp sensors to it and have your fans spin up based on an ambient water temp Delta. Works completely independent of the PC once set up. No need to worry about changing it with new hardware or anything.

Those aquaero controllers look awesome, exactly what I want. Out of budget though, so maybe live with speedfan for the immediate future and plan to put one in with sensors etc at a later date. I'll add another bank of radiators then. Least there is no way too much cooling can be a bad thing.

If you don't have the 1070 yet get the MSI Sea Hawk EK X. The PCB was designed with the waterblock in mind so its basically the best card and the price is good too. Additionally, the newer Corsair ML120s are way, way, way better than the SP120s both from a performance and noise perspective. They are hands down the best 120mm fans you can get.

The back? As in a backplate? I already have an EVGA SC 1070, which comes with a backplate already. Should I have ordered the EKWB backplate then? Also, the ML120s are twice the price of the SP120s. Sixty bucks for a pair of fans is a bit much.

CHA_FAN1 just ties it to 5v, which I presume is equivalent to a 100% duty cycle. My CPU_FAN header supports 1A. How much power do fans drain? Is there an adapter that lets my fans run off my PSU while co-opting the CPU PWM signal?

Otherwise you need an adapter like this cheap and small one: https://www.amazon.com/Splitter-Mol...+splitter+molex Also, if you are talking about the ML120s, you can do 2 of them on one mobo header safely, they are pretty power efficient.

Hmm. Well, I'm doing some math here. My pump is an EKWB pump res combo, using a DDC 3.1. They don't list this normally, as it's only available in their kits, and I'm not sure what the power draw is. I've seen a few generic figures for DDC 3.1s of about 10w, which would put it at 834 mA current. My header is rated for 1A, and I'm currently running two 3pin fans on the same header. As I apparently have no actual PWM fans, do you think I could get away with ML120s slaved to the same PWM signal as the pump? My splitter apparently handles the signal properly, so I could just move the 3pin fans to a splitter on the chassis header and put the ML120s on the CPU header with the pump...

Just a quick clarification, there's two kinds of PWM: Using the 4th pin of the header to send a PWM control signal to the fan's built-in speed controller, and actually applying PWM to the 12V power for the fan. I think the former should be available on any 4-pin header. The latter is rare and used to control fans that don't support speed control and don't react well to voltage control. I'm not sure what Don Lapre is saying these Corsair fans need but since they have 4-pin plugs I would expect them to work from any 4-pin header on your board, but I haven't looked at your specific board.

A lot of motherboards don't actually send a pwm signal on their 4 pin headers but a constant 5v. Many boards only actually send a pwm signal on the CPU header. Example http://www.silentpcreview.com/forums/viewtopic.php?t=66283 quote:First off, watch out for the chassis fan headers, they're not what they seem. This board has 6 fan headers: CPU_FAN, CPU_OPT, and CHA_FAN 1-4. All of them look like normal 4-pin fan headers, but CHA_FAN 1-4 are *not* true 4-pin PWM fan headers. They don't provide any PWM control capability, and in fact act mostly like 3-pin fan headers, controlling all fans, whether 3 or 4 pin, using 3-pin style voltage control. The 4th pin, which should be used to control 4-pin fan speeds while the motor power stays at +12V, is instead hardwired for a constant 100% duty cycle PWM signal (fixed +5V). 4-pin fans will see this PWM signal and always run at full throttle, while the motor power is adjusted 3-pin style to control the actual speed resulting from that full throttle. 3-pin fans will work with these headers as if they were plain old normal 3-pin fan headers. If you run an ml120 off one of these fake pwm headers it will run properly at full speed but the only way to speed control it is voltage control which the ml maglev bearing does not work properly with. You often also see people plugging their pumps pwm control into these and wonder why they can't control the speed, because there is no actual pwm signal being sent. Just a constant 5v. Here is a gigabyte z97n wifi  You can see we get pwm on the CPU header but constant 5v on the system headers. Don Lapre fucked around with this message at 08:02 on Nov 27, 2016 |

I've seen a few generic figures for DDC 3.1s of about 10w, which would put it at 834 mA current. My header is rated for 1A, and I'm currently running two 3pin fans on the same header. A few things 1: Your DDC isn't drawing power from the header, it should be drawing power from your PSU with an RPM sensor / PWM signal to adjust duty cycle on the pump. 2: Do you need your DDC to run at a lower duty cycle? I don't know how loud those things are but my EK D5 PWM is so quiet that even at max speed its pretty much inaudible. 3: I'm not sure if the PWR_FAN has special significance on your mobo, typically only the CPU_FAN is required before mobos decide to take control and shut down if there is no RPMs coming through, but not always. If this is the case then you could: Leave your DDC unhooked and run at full speed, get a PWM fan splitter and hook up your rad fans to the CPU_FAN fan header and control them with PWM and run your two case fans off the two CHA_FAN1/2 headers and get DC rpm control. In the future, look for an Asus motherboard that has a lot of fan headers and supports thermal radar / fanxpert like a TUF. Thermal Radar is a pretty fantastic fan control system that you can tie fan curves to all kinds things including hybrid metrics. Cheaper than an aquero by a bit. rage-saq fucked around with this message at 09:20 on Nov 27, 2016 |

It's pretty damned silent, even when I had it hooked up to the 3pin testing adapter (and was thus running 100%). If it doesn't jeopardize the lifetime of the pump, I could plug it in to the chassis fan header...provided that header can handle the current draw. I'll email ASUS. 3: I've disabled the warnings on the CPU_FAN not being present, it should work fine.

Yeah, I got hosed by asus "4 4 pin fan connectors" marketing once, I'll be super careful next time I'm buying expensive motherboards. The CPU headers are PWM (but only the same signal for both  ), and the other two are just 5v on pwm and use voltage to control speed  Luckily those swiftech 8way pwm splitters exist, though I'd still prefer it if I could run the pumps on a different pwm than fans more easily.

The only thing you would have to worry about is pulling too much power for the actual wire to start melting, which you wont. Also if you are running 2.5" drives they run on 5v. But still you have 24a, more than you would ever use for sata power connectors.
