Mcubed BigNg

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

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.

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

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.:D

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?

^^ sounds about right.

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.

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

Yep.

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.

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.

Chris

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.

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.

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?

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?

:up: You got it man. The original question was: I need something that will shut down the PC in case of a pump failure. I'm looking into getting the stuff from Mcubed (bigNg, miniNg, sensorbus), what all will I need to make this happen. Most of you said all I will need is the BigNg and Sensorbus, so i'll get those and try them out. Thanks for the help guys!

@weihk

Dude - chill.

Firstly - I just spent over $9000 on my pc. I will be using bios shutoff on temp feature. It's retarded not to as its cheap and free and works very well so cost of PC is not an issue.

Further, adding 3rd party hardware can actually complicate the situation not simplify. What if it fails, what if you don't set it up properly. Its not guaranteed to work perfectly.

Saying all that I will be using the big ng and accesories to monitor my system. I think the sensor bus can only handle 2 rpm feeds - e.g 2 flow monitors. I don't know if you can have multiple sensor bus's.

Whats up Chris, I know the BIOS can be used to shut off the PC in the event of the CPU reaching a predefined threshold, but what about the GPU's, the NB, the SB? Can you set the BIOS to shut down the system if one of those overheats?

BTW, how's your new stuff coming along?

I was responding to 'weihk' and his repeated 'get it?'.


I would hope at 800$ each the GPU's have shutoff. As for the NB and SB - they are not so important - generally being passively cooled anyway.

As for the new stuff - very well thanks ....

no worries, and no offence taken

wasnt intended to have a go at you guys, just trying to join in and point out what the guy is really trying to say.

however, i do use a BigNG, but reason for not commenting how to set it up to hard shut down when things fails......is because i only use it for automated fan controll for my WC setup, together linked to 2 water temp sesnsors........and thats it, didnt bother setting it up for hard shut down, cause im too much of a idiot for that!:D

hmmmm......think i need to polish up my posting skills.....otherwise i might get shot in da arse one day for misunderstanding:D

Hmmm... 6x pumps? Can anyone say overkill?? Recommend reading Cathar's latest thread, which covers how much pumpage you should need. I'll say right now you'll probably only really need 3... the other 3 won't do anything at all for your temps, and will just add further unnecessary heatload... but anyways...

BigNG AND extension set allows for a max capacity of 6x rpm monitors, so one mCubed and Analogue Extension set (SensorBus) will handle JUST your pumps and temperature monitoring. Won't have any room left over for fans etc. Also, it can only be used to monitor the pumps - not power them. The BigNG has a max capacity of 40w, and 6x 18w+ pumps is more than 40w. You'll have to power each pump directly off your PSU.

Either way, with the BigNG you have redundancy - it has a passthru cable to pass 4 of the RPM channels onto the mobo - the mCubed handles monitoring and protection whilst in windows, and you can set the bios to handle it prior to windows loading (majority of mCubed's function is only useable whilst in the OS with it's software running). So, CPU Loop pump would be passed thru to CPU fan header. NB Loop's pump would pass thru to NB fan header. That'll be about it for what the bios can handle in terms of auto-shutdown in event of pump failure.

You can hook a DDC's rpm cable up to either the flowrate headers on the SensorBus, or to the fan channels on the BigNG itself... and with 6x pumps, you'd be using all 4 headers on the BigNG, and both the flowmeter ports for the remaining 2 pumps. 4 of the pumps would thus display as an RPM in the region of 4 to 5000rpm, the other 2 would be translated into what the mCubed thinks is LPM (as it'll assume you have the provided flowmeters attached, it's maths'll be wrong converting the DDC's rpm to lpm).

You'll also have the ability to monitor 12x independant temperature probes -
4 analogue & 1 digital thru the BigNG, and a further 6 analogue and 1 digital thru the Extension Set.

And you'll have a mass of burnt-spaghetti-resembling cable to route and tidy... which is the mCubed's BIGGEST drawback.

(I'm in the middle of fitting one to a dual-loop system - see yonder - have dedicated tomorrow to dealing with the spaghetti, which isn't shown in the photos)

Man that's looking really good, I can't wait to see the finished product. I'm with you on the GPU's, for that kind of money you would think that they have to have that function, but I don't think they do.

Ahh hey you're ok, you actually understood what I was talking about. :up:

Thanks for the info Marci, that helps out alot. More than likely I will only have 3 pumps, I was just saying that if I could talk the wife into letting me have 6 then I would get 6, but you know how that goes :p: .

That settles it then, BigNg and Sensorbus it is! Now I just gotta sneak that purchase past the wife. :D

Just so that you understand how mine is setup:

I have a BigNG, 2 miniNG's, 1 Sensor bus, 1 Digital expansion, 6 water temp probes (G1/4"), and 8 attenuators all from Mcubed.

I have 3 pumps in my system for 3 different loops. I just dropped out my Iwaki RD-30 as I'll be using it on my upcoming test bench. I have 3 DDC-2's in my system, 2 with Petra's top and 1 with alphacool top.

On the BigNG, I have my CPU loop and other motherboard related fans:
Port 1 = DDC-2
Port 2 = 2 Yates on my PA120.2 joined together with an attenuator
Port 3 = 3 Yates (2 on the top of my "MM Original Window" and 1 on the motherboard tray in the exhaust port) connected together with 2 attenuators)
Port 4 = Corsair Dominator RAM fan

On MiniNG-0, I have my GPU loop:
Port 1 = DDC-2
Port 2 = 3 Yates on my PA120.3 joined together by 2 attenuators

On MiniNG-1, I have my Chipset/HD loop:
Port 1 = DDC-2
Port 2 = 1 Yate with an attenuator attached to my PA160

On my Sensorbus, I attached the RPM monitors for my CPU's DDC-2 and my GPU's DDC-2. I also have 6 water temp probes attached to it to monitor temp in and temp out of each of my 3 radiators. The water temp probes are G1/4" caps that you can use with a T-line. My sensor bus also attaches the hard switches from my power switch to the motherboard.

My BigNG also has 6 digital thermometers attached to it through daisy chain to monitor my CPU, GPU1, GPU2, NB, SB, and RAM. The bigNG is setup to automatically adjust fan speed and control the pump based upon the temp curve I have for each component.

The Sensor bus will perform a hard shutdown in the event any of the temp thresholds for my 6 digital thermometers, 6 water temp probes, or if the pump RPM signal no longer broadcasts.

This thing gives you total control and monitoring over everything. It's awesome for the control/safety freak. I'll have to admit, I had to spend a few days just getting the wiring down to avoid the "spaghetti" look, but it was worth it.

Ranker
Have you got a pic of your temp probe caps up anywhere?
My PA rads just arrived and I'm doing a rethink of the layout

If you sift through my thread, you will see in the pictures a Tee with barbs on each end a temperature probe. There is also a post with the link.

This is the best method. I have bought the digital sensor extension kit to try and epoxy one into a Tee as seen on the mcubed forum, but do not like the plastic Tees as used in the example.

http://www.xtremesystems.org/forums/...d.php?t=146855

Further to some of the posts, can you just use the mobo temperature max for the cpu and the two "flowmeter" connections on the sensorbus for the other two pumps?

Hmmm...wait does the BigNG shut off the system if the pump stops drawing current? In that case it would be possible to rig up a little shutoff thing :)

It can. But adding the sensor hub has other attractions too and its only as big as a box of matches, so takes little space.

Snyxxx
Thanks I'll take a look. Doing some wiring cuts atm, so I need to make some decisions.

That is exactly how I did mine, except I used a Danger Den delrin T. However, I'm reconsidering it and might switch to a Brass/Nickel T instead since I keep hearing reports about how the DD delrin T restricts flow needlessly.

There's a variety of ways to do it, but I'd rather monitor the CPU and GPU loop with the Sensorbus rather than the BIOS. However, that's working alternative.

Yes and No. The BigNG and Speedfan can be used together to perform a soft shutdown if certain thresholds are hit or in case of pump failure.

To perform a hard shutdown, you must use/purchase the Sensorbus. At which point, you can ditch speedfan altogether.

I'm not. I'm using it to monitor the RPM's of my DDC-2's. I'm using my digital thermometer's to measure CPU/GPU/etc temps.

Sensorbus is used only for:
1) hard shut down
2) RPM monitoring for the CPU DDC-2 and GPU DDC-2
3) monitoring water temps with temp probe for all 3 radiators, temp in & temp out. (6 of these: http://www.performance-pcs.com/catal...ducts_id=20435 attached to 6 of these: http://www.performance-pcs.com/catal...25bacac2675edc)

theres ones that dont 'probe' into the water, alphacool does 2 version, one is a T, the other is inline

i have the T version, but Ranker ones i think would might just be a bit close....

Since I can't really see through the delrin, I'm guessing it probably goes halfway down into the delrin T itself. I'm willing to live with it. I also originally had my temp monitor at the bottom of my EK res (i'm so pissed it wouldn't fit in the side since it hits that wall though). However, I wanted temp in and temp out so I resorted to the T's. The reason I'm considering going with the Brass/Nickel T is for the reason you pointed out. The brass T has the connecting holes a little "farther" out than that delrin T does so that even screwed in all the way, the temp probe won't be obstructing any flow.

However, they're at $10 a piece... and they're quite large. I'm not sure I'll manage to fit them inside my already super cramped Horizon. (PS, wait til you see what I did to fit a PA160 in a Horizon in addition to a PA120.3 and PA120.2)

ranker,

I actually have a few of the DD Delrin Tees. I tried to screw the temp probe into the "top" hole and it seemed to really block the flow or, if I remember right, I could not even screw it all the way in because the tip of the temp probe hit the Tee bottom before the threads were fully engaged.

Did you have to add a spcer or something to make the temp probe fit?

I just redid my loop and confirm that with this Tee (only $3.50):

http://www.sharkacomputers.com/niplintcofig.html

I could only barely see the tip of the temp probe and do not feel it was protruding into the flow area of the Tee. But yes, after adding the hose barbs, this assembly gets quite large.

Or, you could go this route. Basically pulling the probe farther away from the T.

http://img165.imageshack.us/my.php?image=img0681tn8.jpg

sanhacker,

I think the spacer you show might be required on the DD Delrin Tee. I do not think the spacer is necessary on the "metal" Tee you show as I have looked and the tip (at least the temp probe I am using) does not protrude into the flow path at all.

Now that I have just received my cpu back plate, I am going to redo my loop and I will take apicture of this.

Thanks for the spacer picture though.

I didn't use a spacer on my DD Tee although it did almost touch the bottom. The nickel/brass T is ideal as I mentioned but seems to cost a whole heck of a lot more. I'm currently bashing my head with my U2 right now to be working on my Horizon but hopefully I'll have some time soon to see if I want to move to the nickel/brass T along with some other modifications I had in mind.

C'mon ranker, the Tee is only $3.50. I am too lazy to look at DD's site, but I am sure they are about even in cost.

mcoffey,

The threads are G1/4 and I have 1/2"OD hose barbs on each end and the temp probe in the top. I was going to do what ranker did by adding two of these temp probes, but it seems the water temperature delta from before and after the rad is negligible.

It is funny how this little device (bigNG+sensorbus) has made me do a lot of things for it. I ended up doing flow rate tests and temperature probe calibration and other things. I thought it was going to do the work. Actually, it has added a nice facet to this hobby when I was getting bored with the usual stuff.

The ones for 3.50 were out of stock and the only other ones I've found were the ones at MC and those went for $10 a pop. Money isn't a concern for me, but wasting it is. I'm not sure if I'd be better off with that nickel/brass T as it appears to be much larger. My Horizon is cramped enough as it is as I have to ask Top Nurse (the local elephant was on vacation) to sit on it to even screw on my UFO covers.

ranker,

Fully understand about the size. The metal Tee with barbs and gets quite long and bulky.

Just did a couple of the MCubed waterproof sensors into a T. Here are some pics. Took quite a while to get the epoxy right - did it in layers. Also used about 2 inches of tubing on the T also.

Starting ingredients

The epoxy is all done now.

The finished product tidied up with a little sleeving and heatshrink.

Chris

Did you first only coat the sensors in epoxy, then epoxy into the plastic Tee?

Can you show any pictures of just the sensor coated? I saw this done somewhere else, but all the pictures show the sensor in the Tee.

They come already waterproofed/coated when you buy from MCUBED.

I only had to ensure a watertight fit into the T.

why would you coat the sensors? wouldn't that kinda ruin the idea?

"i wanna know the temp of my water, but i'm gonna coat the sensors in gunk first!"

They are digital sensors - the water would not be good for them if they were not coated. As I said this is how they come from the manufacturer - ready for 'dipping'. All you need to do is glue em into a T in such a way thay they don't restrict flow and don't let any water out. I took care not to add any epoxy to the existing coating though.

Chris

yar i understand the coating that comes with them, just pointing out(to syn, not yourself) you don't need to coat them anymore :)

Gotcha :)

Chris

Some do and some don't and with 4 different pix of 'digital sensors it gets a tad confusing.
This is not supposed to be water proof.

This is supposed to be but what's the story on the dual wires?
http://img.photobucket.com/albums/v408/sulk/harz-c.jpg

Exactly Jedda. I bought the normal digital sensors and not the "waterproof" ones seen in the picture.

I was referring to this process in this link and thought you did the same.

If you bought the "real" waterproofed ones, then sorry.

I actually ruined one of the normal ones by sticking it into my reservoir top. The little clear plastic coating is not waterproof as I found out the hard way.

This is not supposed to be water proof.

This is supposed to be but what's the story on the dual wires?

Hmm.. I use neither of those. I use these: http://www.performance-pcs.com/catal...ducts_id=20435

Seems much easier to use except they're analogue instead of digital. I normalize all the temps before using them anyhow.

Yeah, you're on my wavelength.
Thanks for the link. I'd lost track of it.
I've the digital extension and they're numbered and must match. Since M-cube offer only #2 #3 as waterproofed I'd be throwing two away.
Still don't get the dual leads though.
Find the analogue very fragile.

ranker,

I use the same temp probe and calibrate it with the digital sensor as well. However, I still always wanted to try to use the mcubed digital sensor as a test anyhow. However, using the palstic Tee was always a turn-off though.
