Venturing into water cooling. Have some questions on it. - Page 2

Yes, I wanted the flow meter as part of an emergency shutoff for the computer. Without this feature would the flow restriction be worth seeing the flow health at a glance? The motherboard will do a shutoff based upon CPU temps but that doesn't provide any protection to the GPU's if there is something wrong with the loop right? The D5 has an RPM sensing wire that can be plugged into the motherboard so that can protect against pump failure but I was still worried about the pump still working but a blockage in the loop. I guess I'm overthinking the failure modes, side affect of my work haha. I guess the deciding factor would be though that like @Unicr0nhunter mentioned that the Lamptron doesn't have shutdown capability. I'm not sure that the additional cost of the Aqauero would be justified by just this addition. Plus I'm not to keen on how Aqauero handles stepping down the voltage inducing more heat into the system.

Thanks for all the suggestions and bringing up excellent points everyone.

Well, I'm not sure what makes you think otherwise, but I have a Lamptron CW611 and it definitely gets hot just like every other fan controller out there I've ever had or even heard of except the newest Aquaero 6 employs a new technology that reportedly doesn't get very hot at all, and even if it did get hot like its previous versions they sell an optional heatsink & waterblock options for it.

The performance capability of the aquaero 5 is mainly limited by the temperature of the voltage regulators since they become pretty hot when you attach some stuff and use it with lower voltages. The aquaero 6 has no problems in this area and the maximum power is only limited by the current which means you can go to the limits without worrying about the temperatures. ...

Hmmm more research then to correct my false presumption.

Wait..what? what does it do to copper? im assuming corrosion. will an inhibitor help?

if your going with the xspc raystorm cpu block, you can aways just go with the matching xspc raystorm gpu block. matched with some heat sinks for your vram and vrm chips. but a universal block route also means your will still need a fan blowing on your heatsinks.

I've never heard of any issues with a silver kill coil and copper. Not saying there isn't any, just that if so I've never heard of it before.

There has been some reason to suspect silver contributing to nickel plating failures, but nothing definitive that I'm aware of. EK for a while tried to blame their nickel-plating failures on the use of silver, but have since backed off of that - their issues have been more attributed to their plating methods at the time, and Koolance still expressly forbids silver with any of their nickel products - although they pretty much expressly forbid everything else too. And Martin (of MartinsLiquidLabs) still advises against mixing silver with nickel.

All that said, I've always shied away from using a silver kill coil in favor of a biocide like Nuke instead because a silver coil is only effective while water is moving. If you have any dead / low flow zones or turn your system off a silver coil isn't going to be helping much if at all, but a biocide will, and Nuke costs pennies for the few drops you need in a loop. A ~$5 bottle lasts years under normal circumstances.

For sure you are overthinking failure possibilities hehe. I've never seen any loop blockage since I started reading about the water cooling solutions (not that long, but I've read a good amount of threads here and none that I read showed something like this).. I think this is very, very, very (...), very difficult to happen. With the pump RPM wire solution you would have a very good and reliable safety shutoff system, and the best part, for free! Even this RPM monitoring is dispensable (but I'd use it, doesn't harm anything doing it smile.gif) once you look at the reliabiliy of the D5 pumps, they like to last 5 years wonderfuly strong and resilient. And about the flow measuring, once you have good temperatures, the flow rate doesn't matter at all, at least for me. I think that buying an Aquaero just for that is kind of waste...

Not all BIOS can be set to shut down the computer for a low/no rpm signal on the CPU Fan header. Some can, and some will just give an alert/warning.

Having an auto-shutdown or alert tied to the pump's rpm may help in the case of a pump failure / power to the pump issue, but it isn't going to help you much in the case of a leak, but having it tied to flow rate might. That's where an Aquaero can come in handy as it can be setup to give a warning for a small dropoff in flow and then to shutdown the system very quickly in the event of a significant drop.

Plus, monitoring flow rate with a flow meter (as opposed to a flow indicator) is a really good way to spot potential issues before they become critical. A drop off in flow rate can indicate a blockage or a dying pump etc way before you would otherwise find out about such problems. It's also handy to be able to see directly what the change in flow rate is after making any change to the loop, like adding another block, or rad, changing the pump speed, etc.

As I mentioned before, I have a Lamptron CW611 and I use a Koolance flow meter & frequency adapter on one of the channels to monitor flow rate and have an alarm set for it. But that isn't going to help me much if I'm not right there near the computer when it goes off. I've been giving serious thought to replacing it with an Aquaero 6 XT before too long, and it's ability to shutdown the system based on flow rate is just one of the many many features it offers that has me considering the change. It's truly amazing what all it can do.

Another interesting option I've been looking at is EK's Ascendancy, if & when they ever get around to releasing it.

Yeah it depends on configuration with the flow meters, I am using an aquastream xt ultra, whitch is a fan controller, temp sensor, pump, flow meter reading all in one. It has a usb connection and also feeds the rpm header for cpu on the mobo. If the optional flow meter is installed and falls below a certain value, it will trigger 0 rpm to the cpu fan header on mobo and the mobo will go into auto shut down. The unit is a little large though , i put it in my pedistal where i put my 140 x 3 rad.

Yeah on my AsRock Extreme4, GigaByte Z87MX-D3H, and MSI Z87 XPower mobos a 0 rpm signal to the CPU fan header (unless disabled in the BIOS) will trigger a shutdown, but on my ASUS RIVBE I can't seem to get it to do that. I've tried it and all it will do is trigger a warning. I don't see any option in the BIOS to get it to shutdown for no CPU fan header rpm, so there seems no way to get it to shutdown for a pump failure. I've asked about it in the RIVBE owners club thread and got no responses from anyone there who was able to figure it out. It's my only ASUS board, so I'm wondering is this standard for them?

That's what got me started looking harder at the Aquaero 6, since it doesn't need to rely on the mobo's CPU header. Then the ability to also trigger a shutdown at a low flowrate as opposed to just a pump rpm also pretty much has me sold.
