Laing DDC Ultra - Quickie

What is the motherboard fan header actually for? Does it supply extra voltage? I know you can get the 12v from the molex, and the max voltage it can take it 13.2v, does it up it to that? Surely it does not down the voltage...? Speed monitor?

The 3 pin is purely RPM monitoring.

 

[GavX]

oh right, thanks for that. My motherboard has plenty of them spare, sure I could find one to stick it into and use something like speedfan to see how fast it is going.

Ta again

Forgive my neophytery, but why would you want to monitor the RPM of a pump via the motherboard, as opposed to a flow meter or similar sensor?

Always willing to learn

tis cheaper, you don't have to buy any new toys for it to work, just plug it into the motehrboard right away. Also with a flow meter you don't know how fast it is going, just that liquid is moving

 

[VonBlade]

Thanks. I thought that a flow meter would tell you how fast the liquid is actually moving, as opposed to just the impeller (sp) of the pump.

Live and learn.

 

[SwaleSmith]

if I remember rightly my ddc ultra had a blue sensor wire for exactly that purpose

think theres software that links to it and will shut your pc down if you have pump failure, via the mobo headers.

Makes sense as my system ive gotta look at the res's to make sure the liquids actually moving! as ive no flow meter and the systems practically silent.

Something like the Aquaero software me thinks, uses this method of monitoring.

 

[GavX]

could set it in the BIOS if Fan X drops below Y the PC shuts down, no need for software, but could make it easier, the BIOS way might be alot of trial and error

Ok the blue wire as has been said is for RPM monitoring. The reason to do it via the motherboard is all decent motherboards have a CPU fan alarm. The pump operates higher than a normal fan so if it starts to fail the motherboard will know and will tell you. Unfortunately that is all it does though, you are responsible for turning the PC off before it goes bang.

If you run an AquAero you can buy the extra ATX power lead which allows the system to be shut down automatically if any assigned parameters are breached.

I have mine show in my Everest widget and it's set to let me know if it drops down too low.
