Eheim aquarium pump in cooling loop?

Has anyone ever used an Eheim professional aquarium pump in a cooling loop?

I know the hold a load of water but they seem to be the same internals as the ones used for watercooling.

I'm talking about the external filter/pump type that sit under aquariums?

I have one and I'm wondering if it could be used?
 
I'm sorry, I don't understand 'the fluid is not to viscous'. - it's distilled water so the viscosity is low but the resistance from the rad and fan will be high compared to what the pump usually has to deal with?

I have one of these spare and I can pick up a rad and a block. I'm not really sure how to set out the loop.


Is more liquid is a system better? High flow rate better than low?
 
in some rigs ive seen being used they use an oil like substance, not sure how effective that is but if you just using water you will be fine
 
Yes will be fine, eheim stuff is what I used to use back in the day, still got one lying about come to think of it. :)

I'd stick to fairly thin tubing and not monster 1/2inch if possible though from what I remember they are far better with the smaller stuff.
 
That's not exactly what I had pictured to be honest, have you already bought this thing?
 
It depends on the surface area of the heat exchangers and how many you have .... If the flow is to fast the heat wont be absorbed into the liquid if its too slow the fluid will just sit around and get hot ... But it would have to be very slow for that to happen.
 
well i already own it. i saw that a lot of the pumps used in watercooling are exactly the same as the aqarium ones and thought i could use this as a pump and res by simply taking the filter media out and cleaning it. at 700lph it shouldnt be too bad but im just wondering what others thoughts are.

i think im just going to go for it.

i will need a res, rad & cpu block so ill just shop about and post once i have it all running

It might work , but you might find that the external pumps / filters but though they do have a built in pump , gravity does a lot of the work like a syphone tube . Plus when you start the flow they need to be primed first some have a little handle that you pump to start the flow . They haven't got much pressure to them either . It would also take a lot of fluid to fill it .

do you know how many L/Hr that pump is because i am looking online and there a few different ones

700 lph with no head or restriction.

Yeah they do use gravity but once it's primed it needs no 'fall' to continue working. They only need priming if you let them fill with air, I have a res that will sit above it so that won't happen. Flow rate is as stated with 0 resistance as I've tested it with a very scientific bucket.
As for pressure, I'll have to wait and see but it should be ok as long as the water keeps moving at a reasonable rate.

Fluid amount = 6ltrs. I have got 6ltrs of distilled water here. Cost about £15!

I would think it would have very decent pressure since they are designed to be squirreled away in a cabinet below the aquarium and have to pump up to it.

I'm just curious, do you know the model number of the unit you have?

My wife and I used to have three koi ponds in the back yard and I have a couple remote pumps, but they are extremely too powerful for a system loop. :)

Yeah I have a big koi pond too, but the aquamax and superfish pumps I use on that are 10000 litres an hour and could never be applied here.

The Eheim is a 2224. The pressure should be fine as its designed to fill the canister to the top and work as a pressurised unit. I have a res though so it doesn't suck in air.

I'm only cooling the cpu at the moment, until I can afford a 670, and with 5-6 litres in the loop I think that cpu would struggle warming it all up even without the radiator.

I'm thinking of going pump - rad - cpu - res but I may end up putting the rad after the cpu. It depends on space and tube lengths.

That is a nice unit. My sister and bro-in-law used to do aquariums and had similar. They had fresh and saltwater. Both have health issues and it was hard to keep up with then and they had a friend that wanted to buy, so he took equipment and fish. They have visitation rights. :) The larger pump I have translates to about 10000 litres, 2600 GPH (gallons) in the US. I'm letting my EX take the pumps this spring. The fish are in a friend's huge pond and I get to see them. :)

That amount of water in the loop surely has to keep the system cool. It will be very interesting whenever you can get to it to see how it works out. Good luck.
 
well, distilled water, tubing and all the bits arrived today. i need to pull my H100 out of my build and put it into a friends and then ill be able to set it all up and test before putting it in my rig. Hopefully by the weekend. Im trying to decide whether to delid or not.

So the system I currently rigged up to a bucket of water and running in my shower. I have 4meters of XSPC tubing connected to the original tubing and the rad. I ran sysclean through it for a few hours and now it's just running on a cleaning cycle. Even with the ridiculously long tubing runs (I don't want to cut them yet) the flow rate remains unchanged. That rad has hardly any restriction!

When I get more time I will get it installed in my rig and see how the flow rate changes with the CPU cooler attached.

I have noticed that the pump canister takes a long time to be purged of air. A recommendation on an aquarium forum says to lay it on its side for a good 20-30 mins and to give it a shake. Sure enough after doing this all air is removed and the pump runs pretty quietly.

I think this might actually work. I'm going to try and set the rig up outside of the hole under my desk where it will eventually life so I can take some footage and pictures for you guys.

If you have seen my original thread about a budget cooling system then I have added quick disconnects to the list as a later addition.
