another is my MCP 350 dead

post #1 of 9
Thread Starter 
Hi guys ok well if you been flling my threads you would know I just built a new system and W/C it by now.

My pump was working fine in the past with my old system. Back info on spider ITX:
The pump was just cooling the 4890 gpu that had a swiftech full gpu W/B and 1 Black Ice Extreme 120mm Rad and the pump had the xspc res top.
It never gave any issues or headaches.


Now my Babyship build had issues here is the loop:
Start from pump with res top--->120mm Rad--->Heatkiller 3.0 CPU W/B--->Res Top.

Now the first time i built it I was removing air bubbles and plugging and unplugging the power to remove bubbles. I finally got the loop free of bubbles and the system was working fine for 2 days until I turned it off for the first time while i went to frys to return my zalman cooler.

When I came home I freaked when I saw my temps go to 168F and climbing. I turned the system off and rebooted and same thing. I was oh now, so I opened the system and noticed that the pump was not turning on at all. I unplugged and plugged and had no luck. At first I thought the M/B header was fried since i was using the 3 pin to power it and read rpms. So i tried the 3pin to molex and nothing as well then figured it was the psu rail so i tried another rail and nothing still. By this time i was uber sad.

So i wrote a paper that said Babyship had a heart attack awaiting for transplant Stat! LOL

I watched a movie decided to give it a try and presto it worked again i was like ***????????

then i unplugged it and it didnt work again, I was like huh????? so I then unplugged and it tried to start up and with a little luck it spum right up again and it was working. I unplugged it fromt he 4 pin molex and back to the 3 pin and it stuttered worked for a second and stopped. I was NOOOOOOOOOOOOOOOOOOOOOOO. tried molex and nothing again did I finally brake it i thought to myself.

So searched the forums and one member said to tap the hell out of it so i did and it worked I was awesome it worked. So this is where I am right now, after tapping it i figured leave it on until my replacement comes and see if that one gives me better luck.


though I truly dont want to re assemble the loop.

thing that I noticed at first when it failed it was uber hot. figured it was thermal related though was proven wrong since it gave me issues when the pump was cold.

Then i realized it when i tapped it wouldnt work until i tapped hard enough and made the pump/res top lean forward a little bit and that did the trick.

So I left it tilted and shutdown and re started a couple times and it worked. Thats how I am typing this thread and like I said before I am just going to leave the pc on all the time until new pump gets here and I will go from there. If the new pump gives me same issues I am going to assume I have one to many 90 degree fittings and it might not like that. Specially the one that actually is attached on the outlet of the pump.

refer to pics for my set up.

Or culd it be that I have to much water on the res that it does not have enough room to expand or shrink when turning on and off? I notice when it 85-90% full i could see it drop levels when i turned the system on and return when the system was off.

When I built the new system i filled the res top to 97-98% literally a small bubble left on the top of the res top. Should I suck out some whater?

Water in the res wont make a difference imo, I had the same res for years and always filled it totally.

If it's getting hot when it fails, what it sounds like is the pump is jamming and then the heat from inductance is just building up in the coils.

Sounds like you need to RMA

Try soldering on a new molex connector. Sounds like a possible loose connection that could be either at the plug end or at the pump end.

Sorry OP OT, But do you think you can fit a dual 120mm rad in there. This a nice setup you got here. Makes me want to buy that case for this motherboard/cpu combo when I upgrade in the summer.

It sounds like a break in the power like Martin suggested. I recognize those enzo fittings and res hehe...

using the standard rads size rads NO, you will have to use a stealth 240 rad from hardware labs. to actually go on the front.

But in my case I think I will got slim 140mm rad on the top and dual slim on the front.

Since i will add the gpu loop.

Yeah I highly recommend the case and a modular psu.

Like someone else suggested the silverstone stryder modular psu with a short cables would work best. for a cleaner look

If it was a break in the power, it wouldn't be hot...

DDC pumps run hot, they all do. I have measured up to 60C on the base. Pump casing is plastic so there isn't very good water cooling like the D5.

I have also had issues with pumps not turning on due to loose molex connectors many times before, and broken wires. He also noted that the issues appeared while cool.

When a Laing pump dies it is usually due to one of the FETs burning up or water damage. Eay to see if you open it up. Black PCB means burned up FET...White residue means water has been present and there could be water damage.

If it comes on when shaking, I would suspect a loose connection..especially since it's not a factory plug.
