Water pump has packed up, which should I replace it with?

post #1 of 7
Thread Starter 
Last night my swiftech MCP350 packed up. It lasted 3 years which is longer than I thought it would. My question is, what should I replace it with?

Luckily it's packed up nearing pay day after my latest build. So next week I can get a decent one without worrying too much about the budget.

I've heard good things about the Laing D5's, and there are lots of different tops and mounting ideas. What is going to be my best bet? I currently have a separate res in my loop, but it's nice to have options for future builds.

I quite like the look of this koolance pump top with the option to put a reservoir straight in the top, but it does seem quite pricey when compared to the ek ones.

Or are there other options out there? Are the aqua computer aqua stream pumps worth the money? I'm not sure about fittings for those yet either.

Thanks for any advice guys.


Edit for making my mind up. I think I'm going to go for the koolance top on the d5, I have koolance fittings and a Koolance 380a block on my CPU. I've been very happy with the quality so far and it seems like a good pump and top.

Anyone have any reasons not to go for this or have any other suggestions then don't hesitate to let me know smile.gif

The koolance top for the D5 is top quality (pun intended!).

A friend gave me a D5 that was built in 2006. It still works...

However, a DDC should last 5 years of non-stop operation. Did you have an aftermarket top, PCB mod, or the XSPC restop? Was it hot when running? What happened when it died? I ask because a dead pump can compromise all your system.

The Koolance D5 has an rpm signal. Swiftech's one does not (at least the Vario model, the non-controlled MCP655-B does). Then there's EK and XSPC which I think do have them, and perhaps Alphacool.

Mind that there's also the PWM version of the D5, by Swiftech and XSPC (I think), I'd get that if possible, but I haven't found it in Europe.

Hi, thanks for the reply. I'm not sure at what point the pump broke down, I'd been using the comp the night before with no issue. Then the following morning booted it up and it wouldn't post because the mobo thought there was no CPU fan running. The pump I had has a tachometer output for plugging into the CPU fan on the mobo. So I jumped the psu and tried just running the pump, but it was only vibrating every few seconds and wouldn't fire up. Gave it a few taps with a screwdriver and it would fire up. It has standard pcb, and has 3.2 stamped on it. I was using an ek pump top that I'd fitted about three weeks ago. It never got very hot and hadn't missed a beat before.

I opened it up but without knowing what I was looking for I couldn't source the fault. The pcb looks fine with no obvious scorching or failed solder.

The worry for me is I don't know at what point the pump failed the previous night because I don't think the pc would shut down when the pump failed. Hopefully the CPU didn't get too hot! I didn't have my monitoring software running at the time either.

I think I'll go ahead and order the d5 and koolance top this evening.

Thanks for your input.

I don't know what could have gone wrong, I'm no expert at that frown.gif

Perhaps bmaverick could help you on this.

I'm also afraid of what happens when the pump dies. If I take the rpm wire of my DDC off the header, it won't even beep, and there's no option to configure that in my motherboard. However, you can use Speedfan (or an Aquaero if you're rich) to shut the computer down when the tacho signal is 0rpm.

I hope your new pump lives longer smile.gif

Well I got an XSPC D5, with an ek pump top and mounting kit. Couldn't get the Koolance top delivered next day and was in a bit of a rush. I've just got to say I'm over the moon with the D5 so far. It's variable speed which is nice, and knocks the socks off the DDC, so much easier to bleed the system because of the flow rate. It practically bleeds itself! It's also a lot quieter even on the highest speed setting.

Thanks for your input cloppy. I too hope it lives longer smile.gif

The D5s are awesome pumps. Glad to know you're happy smile.gif

I see that you've got an Asus 280X, are you watercooling it?

I will be but I'm not at the moment. The directcu cooler is so quiet and efficient I don't really need to have it under water yet. But I'm going to get another two and get them under water in the future.
