leak testing loop with 7.2v battery

red eye · 28 Sep 2013 at 18:38

Right my old psu has given up the ghost while attempting to bleed my new loop. Computer repair shop down the road have no cheap genric psu's.

But I do have a 7.2v battery or two for my rc cars, would this be enough to power a 10w lilang ddc to bleed and leak test?

It'll run it probably, but not for particularly long I suspect

Not got any random old power adaptors kicking about?

no random adapters well nothing 12v although I can pull out the back up lead acid from my alarm system.

edit
god and bad news. the good just kicked the psu now its working....the bad, the ddc is quite noisy I also have to rethink the inlet and oulet for the tube res. top inlet and bottom outlet is sending airbubbles though the loop

Might be worth picking one of these up in the future, they can be had for under £20.

I bought one to run my external radiator setup... pretty handy to have to test stuff out without having to have a full sized psu.

Exactly what I have. Need a look when you get it though, a few friends of mine have them, and some, mine included, don't have any connection on the -5v line. Had me head scratching for a while with one of my components until I noticed it.

+1 to the molex power supply, they are so handy.

As for your inlet/outlet issue with air bubles, if the inlet is submerged it should be ok (this is the setup i run, though i do get the occasional bubble, not sure if this is related though

). ofc its better just to have both inlet/outlet connected at the bottom of the res though

CNice one khemist that psu looks like ie will be handy and better then a pc psu (leSs wires) I'll be getting one of them when I find one.

Divx, only way I can fit the res in my cm690 is to have it hanging from the rad by the hose.
I can stop the the water fall sound effects by filling the res right to the top. But I have bubbles that will not budge. I need some sort of tube

You can pick up a good psu for £10 if you look about,ive got a dell 350watt for testing bits.
