pumps burn out , over and over again - Page 3

post #21 of 29
Did you see the graph at the end? Higher flow rate = higher energy consumption by the pump. Higher energy consumption = more heat.

I think the XSPC reservoir lowers restriction letting your pump flow faster. That is great for the cooling performance of your loop but it causes your pump to run hot.

That's what I think is going on anyways... I don't think it has anything to do with the type of coolant you are using. I think the problem has to do with the electric motor on the pump itself. It is overheating one way or another.

My 2 cents...

From the thread I linked.

A heatsink to cool your pump
http://www.frozencpu.com/products/11...c107s156#blank

and a graph showing how power consumption rises with lower pressure and higher flow.

if i use heatsink in the next pump.... maybe runs more cool.... but ... i dont want to do more "experiments".. the first pump burns out and take a 5850.... the second an third the pc shoot down.. and dont burn out anything....
i read the 655 is good pump and i dont find people it has burn... maybe in a good buy...

Why not step up to a different pump design? The liang D5 is supposed to be one of the biggest baddest PC water pumps.

I'm not a water cooler myself so I don't know everything about water cooling but I have heard a lot of good things about this pump.

EDIT: I think the 655 you mentioned is the same pump under a different name... Sorry.

Im an EE with a focus on motors. I would like to help, but I think you need to post pics of your water cooling loop, as well as every detail about it.

I run VW/Audi G11 & G12 in mine... then again, Im running Eheim 1250's. Most of the PC coolant additives that sport corrosion inhibitors of some sort are really just someone repackaging the automotive stuff into a smaller bottle and adding a markup. G-11 and G-12 wont corrode brass/copper, or aluminum, as they are inhibitors for both cathodic and anodic reactions.

The pump top CAN be the problem. I would suggest a process of elimination for that. Try a different volute and see if the problem continues or what.

the res top can be the problem ... i suspect that i have two options :

1) buy a reservoir apart of the pomp and buy a top like zern 12... i heard is really good ... and put in the pomp a heatsink whit a thermal panel.

2)buy a reservoir apart of the bomb and buy the pomp 655.

i really think the res top of xspc dont work well... tree pomps and tree burn out... the next time i buy a pump i meant to be the last one.. and not touch my loop for a wile...

With the DDC-1 MCP350, how was the pump mounted in your setup? Was it on it's side? Was it upside-down? Was the pump in a well ventilated postion within your case with proper air flow going around it?

You had mentioned using automotive antifreeze. If you use the orange DexCool coolant, it WILL kill the pump or any brand of pump in time. There are plenty of write ups of how DexCool (or long-life coolants) are a no-no to use outside the automotive realm. The only good coolant from automotive to use are the "green" colored types that come in the concentrated jugs that you would need to mix at the maximum 33% to 66% distilled water. Or a 1/3 to 2/3 ratio. Exceeding that to a mixture level of 50/50 may have an effect on pumps because the Ethelyne Glycol (EG) is not a real lubricating fluid.

The only real automotive antifreeze that can be used in any mixture ratio is Propylene Glycol (PG). PG has properties that will enhance the lubrication of any given pump.

i have a case eurocase space jam modded .. ist not a very large case... i put the pump inside the dvds bay, i put de dvdrw in the last slot and put the pump above ... i dont think the ventilation was really good....
i use a antifreeze color blue..

Well, if you would remember years ago Swiftech sold a DDC-1 + RES combo for a short time that would fit into a DVD sized opening in the computer bay. They had stopped selling it when the heat of the pump killed itself. The part number was MCRES-1000. So, having your pump there is a real no-no. See the image below for the Swiftech product.



ALSO, ...

The blue automotive antifreeze WILL kill a pump!!! It contains Phosphoric acid. This is the same stuff found in naval jelly to remove or convert rust. It will destroy the impeller and internal magnet of the pump. It will also destroy your RAD by dissolving the brazing solder joints. Depending on which blue coolant, BMW, VW or Toyota, the acid concentration varies slightly.

The PG Pink is best.
