Mcubed BigNg

[Baleful]

I've been looking into the BigNg and MiniNg for my new setup, but I really only need something to shutoff the PC in the event of a pump failure. I'm not looking to control fan rpms, or monitor temps, I just need something that'll shut off the PC in the event of a pump failing. My question is, what all will I need for this? I'm thinking just the BigNg and sensorbus, or do i even need the sensorbus? Also, how hard is it set this stuff up, as I have no experience with this kind of stuff. Thanks for the help guys.

if your pump plugs into the motherboards then that's all you need. most motherboards allow you to set it so that if whatever is pluged into the cpu header fails or the rpms go below a certain amount the com,puter shuts itself down

[Baleful]

The pump is the DDC w/ Petras top. The MB i'll be using is the 680i, I'de rather not have it hooked up to the MB (can this pump even do that?). I would just rather have the piece of mind in having the pump hooked up to something very reliable to shut it off in case of failure, i.e. the BigNg or whatever.

[elfy]

the ddc is powered from the 12v molex, but it has an rpm monitoring cable that can be plugged into the mobo

[Baleful]

Ahhh ok cool, I didn't know that (I don't have the pump yet, will be here Friday). I guess for now I could use that, but i'll eventually need something else, as I will have 3 loops, and possibly 6 pumps (2 pumps per loop cuz im crazy)..... I dunno, depends on how much i can sneak past the wife lol. So what all will I need for this? Keep in mind I JUST need the ability to shut the PC off in the event of a pump failure.

I am still learning my bigNG. I think you will also need the sensorbus that has two flowmeter ports. I attach the blue RPM cable from the DDC (3-pin fan header) to this flowmeter connection and the software shows the flow rate. However, there are only two flowmeter connections. I am not sure if you can hook the pump's RPM cable to a fan connector. Also, the sensorbus device is required for the auto shutdown feature. The usual case wire that runs to the mobo plugs into the sensorbus and another wire goes from the sensorbus to the mobo to provide the shutdown signal.

I eventually decided to just let the computer thermal shutdown by itself if the pump fails. I accidentally left my pump unplugged and started the computer for some Prime 95 testing. I came back and the computer was off. I started again and watched the temps skyrocket and did the same thing and turned off.

This is easier and cheaper.

Yep, just set it to auto shut-off in the BIOS if the temp. exceeds say 70C on a C2D or sumthing. Lol.

Lol no thanks, I have to much invested in my equipment to do this. So the BigNg and sensorbus it is then. So this is all i'll need for the auto shutdown in the event of a pump failure?

[Ad1tya]

^^ sounds about right.

[boo1010]

on your bigNG do you have an lcd attached? if so how easy was that to do?

Sensor hub comes with wiring to connect between your case on/off switch and motherboard. It will shut down your system just the same as you pushing the button. In fact they include a switch in case you don't have a button. lol

You could always just set your computer to shut off when the cpu reaches "xx" degrees C.

There should be an option in the bios for it.

As I said in the above post I DO NOT WANT TO DO THIS. I'll have to much time and money invested in the system to rely on the BIOS to shut things down in the event of a pump failure. Plus i'll be running 3 loops with a possible of 6 pumps. My question was what parts will I need to make this work, and from what i'm gathering from previous posters, I will need the BigNg and sensorbus.

[Senater_Cache]

whatever you do, DO NOT run your pump off of any mobo connector !

[Jedda]

I will need the BigNg and sensorbus.

Yep.

[FatboyHK]

I think you need a flow sensor to accurately monitor flow rate. I have a pair of Swissflow and I am working on it to make it work with my Aquaero (I need to divide the signal rate of Swissflow before It can work with Aquaero)... However, I heard that it can work on-of-the-box with BigNG.

[Jedda]

Yeah it can, because of how the BigNG calibrates. I got on to Swiftflow AG about sourcing them and they've changed their practise from before. They'll now sell direct and can take paypal. They quoted a reasonable price too.
They have far lower hydraulic drag than the U-shaped things you see offered for the M-cube gear.

Having just had a big package arrive from mcubed this morning I would be interested in getting a couple of these. Also if someone has a solution for temp monitoring that would be good too. I need to cut the 1/2" tube in half and just stick something in the middle.

They quoted me 25€ each with 8.5€ to ship it to Australia. Which is much better than the 50€ they retailed at before.
You can buy several temp sensors for water or take a M-cube digital sensor and cover the end in epoxy then stick it in your T-line or where ever you want.

I guess I just don't understand why you don't want to use a feature that was integrated into every BIOS for precisely this reason- Why are you so scared of using a BIOS feature to shut down your PC if it hits over 70C? I know this featur saved me once, my pump got shut down mysteriously and my system started overheating...All of a sudden the PC shut off and my processor was still intact

Save yourself a lot of money and time and just use a BIOS feature that was put there to serve precisely this function.

Am I missing something here? So eventually as I complete my build, i'll be able to hook up atleast 6 pumps to the MOBO... I think not. I will have 3 loops, 1 for CPU, 1 for GPU, 1 for NB and SB (eventually). There will definately be ATLEAST 3 pumps and possibly 6 (2 pumps per loop). That's why I don't want to use the MOBO.

[Burn]

My point is, you don't have to hook them up to your motherboard. In all honesty, you can't because your motherboard isn't designed to push that many amps through that small a gauge wire. You need to hook up all of your pumps through your power supply and use your BIOS monitoring tools to shut down all of them when your CPU reaches a pre-set shutdown temperature.

[phcjpp]

I agree you should be using the bios to shutoff. One question does occur, what about the GFX cards - do they have temp shutoff. Also NB and SB - do they have temp shutoffs. If not, you might need the sensors.

Please tell me no one is seriously thinking of driving pumps from the motherboard.

That's another point I guess I forgot to point out. While I can use the BIOS to shut the system down if the CPU reaches the predetermined threshold, I don't think you can do the same for the GPU, NB and SB (I could be wrong though).<-- Anyone know if you can do that?

[weihk]

the guy is saying he'll possibly have 6 pumps

and the guy says he dont think his mobo has 6 fan socket to connect upto 6 DDC or whatever pump RPM signal cable

and the guy has said even if it has 6 fan socket for 6 pump RPM signal sensors, he dont think his mobo BIOS has 6 '' shut off on XX temp / shut off on below 50 RPM '' option for 6 fan sockets

get it?

and the guy has also said he will be spending A LOT OF MONEY on the computer, therefore, he wants to have TOTAL controll over it via A 3RD PARTY HARDWARE

get it?
