Water cooling pump dying?

[PopcornMachine]

primed? I have t-port I'm using to fill the top of the loop, and the pump itself has water in it, it that's what you mean.

just won't flow. doesn't move.

If the new on has the 3 pin connector with single wire for RPM monitor from mobo fan port then use it.

The new one goes straight to a 4 pin molex. No 3 pin connection. At least according to specs, but ill know once the pump is actually in my hands.

My 655 goes straight to 4pin molex as did my old mcp355. Wasn't til recently where I saw pumps with 3pin connector; shows what I know

I think I'd prefer the 4pin molex.

I think you said you connected your pump with a 3pin to 4pin molex connection. Ever try going straight to the mobo, just out of curiosity?

No, its 12-15w pump, not sure that would be good, pulling that much power from motherboard fan header lol.

I just said fuck it and bought a brand new MCP350 from PPCS

So, how much does a MCP350 pump cost from PPCS these days?

The MCP350 pumps I offer are "new" too and $35 shipped anywhere in the USA.

Too bad the one that died was one of yours already. Do you offer RMA?

Way too much.

 

[cadaveca]

Way too much.

But less than they were about a year ago or so. Can be found for $69 near local to me, can't imagine they'd cost much more for you guys..

If the pump uses an impeller then it will make a chattering sound when it is going bad.

True, but that's way too much to pay for a standard DDC. A 355 or 35X can be had for not much more money, or a D5 for about the same. $35 is what they should be selling for.

Regardless, I don't think the pump was a total loss, he probably just got another for the hell of it. The ceramic bearing isn't/wasn't bad.

You gonna tell him to break out the soldering iron?

He can afford it, anyway.

And yeah, you're right about the prices, but they do seem to be falling back down lately. I'm eager to see Swifttech's new pump and AIOs, but they are probably still a few months out yet, so now water for me until then, I guess. I was kinda hoping that might spur things even more downward, but given the market as of late, charge premium prices for those that go full-out seems to be the norm now.

Yeah I have had a few pumps with just 3-pin but they have never seemed to work off a fan header anyway. The D5 Vario I recently got has 4-pin molex plus a 3-pin with a single wire (as that is all that is needed for RPM monitoring).

 

[Sasqui]

D5's all the way baby. The only negative I've noticed is the older ones tend to be noisy. The new ones are absolutely silent... only hear it when there's bubbles that haven't been captured by the res. Pumps a shit load of water.

 

[MxPhenom 216]

I cannot run a D5 pump due to my Res/pump top only works with DDC pumps (MCP350,355, and MCP35X)

The DDC-1T aka MCP350 is 10W and runs easily off of the CPU header. That's how I've had mine since 2003 running nearly 24/7/365.

MCP350, maxes out at 12w at 12v. Most motherboard headers are 1A (12w). So Running a MCP350 while still not exactly over 12w, is still pushing the limits of the header.

 

[MxPhenom 216]

New pump came. Definitely has a 4 pin molex and a 3 pin for rpm monitoring.

 

[erocker]

even if bearing fails, it would turn. unless bearing is made of plastic.

I've seen this happen enough times (with various metal bearings from industrial to automotive to skateboards) to confidently say that you're wrong.

 

[TheoneandonlyMrK]

funny, my pump just died too. it was a combo res with pump inside. turned on my system friday and noticed overheating, then pump not pumping.

got a new mcp665-b, no res, and can't seem to get water to go through cpu block. took it off and washed it out don't see any blockage.

very annoying process so far.

Tip I order three meters of tube each mess about and use it to sort of , in situ flush all of the loop

Now that you got the new pump, you should PM bmaverick, and ask him for ideas on how to fix the old one. Might be worth playing with as a learning experience.

After like 10 years of selling these pumps, I doubt anyone knows them better.

At the same time, the design IS 10 years old, and hopefully the new one gives you better temps.

 

[fullinfusion]

maybe the bearing, but it should run for long term

There is no bearing in that pump, just a ceramic ball the impeller sits on.

I couldn't agree more, even after reading post #41. Young shaver

True that.

True that.

What's wrong with post 41 old shaver?

The box of the pump says 10w, but if you go look at the specs online at Swiftech website is has a range of like 8w-12w, meaning 12w is the maximum. I don't run any fans on my motherboard anyways, I either have a fan controller or what I have now, the NZXT Fan Power Hub that works really well.


I might take the pump apart and see if anything is blatently obvious, as it has been running solid as of late, hasn't turned off. But this new pump will be going into my system this weekend. Just need to go get a Torx screw driver (That's bigger then T6) to be able to get the head of the pump off to put onto my reservoir top.

the failure u are talking of is catastrophic. the forces in a pump are much smaller. unless the plastic housing cracks and breaks and dislocated i dont see how it will have enough force to stop the motion.

one thing that might happen, is that the impeller broke(which happens to be plastic) and tiny pieces got lodged and stopped it from moving.

Point is, if the pump stopped because it was falling apart...you now have crap in your loop that you should clean out, or you're gonna kill the new one fairly quickly. Pull the pump apart, investigate why it died, and deal with the problem fully. Chances are it's a simply electrical flaw that can be fixed really easily. It's not like these things are complex.
