Default Via Aqua 1300 Submerged

I am in pursuit of a WCing system with a pricetag of $110 and solid performance.

So far the components I am looking at are as follows:
MCW6002 CPU block/Maze4 - $40
MasterKleer 3/4OD-1/2ID tubing - $5.70
Wormgear clamps - $5
Home-made Res (acrylic container with 2 bulkhead fittings) - $7
'77 B-ville core - $18
Home-made shroud - $2
2 - Sany Denki fans - $10
Pump - Possibly the Via Aqua 1300 - $20
Optional - Homemade fillport for ease of fill-n-bleed - $3
RTV Sealant - $3

Setup - Submersible pump inside the res>>HC>>CPU block>>res

The single item I do not have experience with here is the Via Aqua. I have read stories about leaking (taken care of by submersing it) and dependability problems. I have also read stories of people who have been using them for nearly 3 years and having no problems. My thoughts are that by submerging it the coolant itself helps cool the pump. While this adds some heat to the loop it also helps the stability of the pump itself which is of primary concern. By using the double rad with the Sanyo Denki fans I think the added heat from the submerged pump will be more than offset by the heat removal capabilities of the HC/fan combo.

I would be interested in hearing from anyone that has tried such a setup or has experience with the Via Aqua. Yes, I know its an inexpensive line of pump but my main interest lies in determining if by submerging the pump and accomodating the additional heat in the loop we can offset the primary concerns about the pump.

Shipping of course would be additional to the prices I have posted.

you can probably find a via 1300 for 20 $ shipped.
running it submerged will probably add some heat to your loop.
the pump is not leaking if the barbs are correctly mounted (teflon tape, silicon...)
i have one running for 6 months and don't have to complain yet.

Excellent to hear Miladiou.

I think the heater core/fans can probably handle the heat considering how little that pump actually adds to a standard system.

The shipping really shouldnt be that bad considering the main things that people need to order shipped (for most) would be the waterblock and tubing/fittings (I would suggest McMaster.com here, they have all the needed fittings, tubing, and clamps at some pretty nice prices and are very reasonable on shipping cost). The fittings/tubing could also be picked up at a local hardware store. The res is little more than a standard acryclic food container available at many stores locally. I suggest spending the extra buck or two and getting one of the thicker walled (1/8") ones.

The fillport would simply be a barbed one end/male threaded other end fitting secured in place with a washer/RTV sealant and a thin nut. A simple screw on cap could be used when not filling/bleeding.

The bulkheads would be 3/4" female thread-3/4" male thread secured by sticking the male thread through a drilled hole with a barbed/threaded fitting screwed onto each side. Total cost per bulkhead is right about $2 including washers/sealant.

The shroud cost would run anywhere from $1-$5 depending on material used and tools available. It could go from re-enforced cardboard up to 1/4" Acrylic/Plexiglass to 26guage steel. Pretty cheap to make and very easy. Material type depends largely on available tools.

Well, it probably won't die as quickly if you run it submerged. I still think you should use a Mag 3 instead, though.

Yeah, I have to admit I do have a bit more confidence from what I have read in the Mag3. The main goal was to try to keep a decent system at right about $100 give or take a little bit.

The benefit of the Via is that basically you can get two for the same price as the Mag3 with fairly close performance on a 1 to 1 comparision. For the few dollars difference if I was not going with the Via Aqua I would probably jump to the Mag5 which should be able to achieve decent flow through most high flow required waterblocks.

I am currently using a Hydor L35 which would most probably also make the grade for right at the same price. It also only puts out 23watts which would be pretty nice considering it would add a wee bit less heat to the loop.

If you can think of any other ways of saving to break that $100 mark and wouldnt hurt the system too much please kick in

The Mag 5 shows no improvement over the Mag 3 in cooling performance because they're both rated for 10.5' head.

Actually according to the PQ curves on the two pumps the only head at which there is no difference is right about 6'. From 1-5 feet the Mag5 has a substancial (10%+) flow advantage. It also gains an advantage as things get more restrictive beyond 6' as well. At 7' its only around 4% better flow but it continues to increase its margin over the Mag3 up to having twice the flow at around 9'.

Admittedly if your system basically equals a 6' head there is no difference but for more or less restrictive systems the Mag5 will increase flow.

Understand that any PQ curves supplied by the manufacturer should of course be viewed with a grain of salt I was using the chart supplied at Marinedepot.com for the PQ curve chart. The down side is that due to using 10 more watts of power to run the Mag5 it adds more heat to the loop as well. The bottom line being.....heck if I know exactly

I do think at no point would the Mag5 actually perform worse and depending on the restriction in a loop and the type of waterblock used the Mag5 will perform better...how much better is a good question however.
