Dead pump!

I got this pump back in March: http://www.frozencpu.com/products/1...?tl=g30c107s1802&id=JdfQZqfB&mv_pc=3644#blank

This morning I heard the strangest noise coming from my pump. Then it started this grinding/chattering noise every few seconds. It would stop, try to spin but just end up shaking back and forth, and then stop again. Over and over, very loudly and annoying.

Disassembled and drained. Feels like something is off-center in the pump or something. It no longer spins freely (if it's supposed to in the first place). Does the same thing in open air as well.

Only thing I can think of is that for a while the reservoir was getting a bit low, so every so often I'd hear it spin up as a bubble went through. It was probably like this for a few weeks. But I filled it just the other day and that stopped.

I'm probably going to install my old TRUE so I'm not without my desktop over the next few days, but I want to get the ball rolling on the replacement immediately. Should I replace it with the same model pump, or is there something better out there?

Also, any idea why it would up and break on me? Should I do an autopsy and post pictures?
 
Probably a manufacturing defect where the alignment was slightly off or something like that. Over time it wore down the bearing, until it wore it down enough to cause complete pump seizure.

The Laing D5s aren't known for doing this, but it can happen. I don't think that's a user fixable part, but you may be able to claim warranty on it.

It'd be hard to tell it was broken by looking at it. It didn't come apart or anything (or I just don't remember how it's supposed to look). It just doesn't spin right anymore.

Decided to look at my EK 680 block to make sure the plating wasn't flaking off, since I have everything mostly apart anyway. Well, it wasn't, but there's this black goop inside. Think it's from the failure of the motor? I don't see anything in the block that could be shedding this stuff. On the other hand I don't remember seeing any in the reservoir.

are you using distilled water? casue that may remove other ek block flaking. my d5 vario had bubles going through it for a whole year, and the pc is on about 16 hours a day.... no problem what soever.
 
EK blocks have been known to be shit in the past two years. I'd suggest anybody to stay away from them. They're made with poor QC and are infamous for corroding or going shit in other ways and taking whatever is in the loop together with them. You should have gone with an Aqua block, who's making the best blocks nowadays.

Distilled water with no additives and a single killcoil. I've read up on their flaking problem - yeah, sure it's the coil :rolleyes:

Unlike my other EK block I've seen no nickel particulates in my res...only this black goop in the odd areas of the VGA block.

Yeah, regretting it now. They had the only 680 blocks in stock at the time I bought them. Should have waited.

Still though, if this is the block's fault, where is the black stuff coming from? The nickel flaking should be silver and I should see obvious signs of it missing from where it flaked off.

It looks greenish, looks to be oxidated rather than corroded.

Maybe it's just the photo - in person it looks dark black. Don't really see a hint of green.

Replacement pump arrived and is installed. No issues so far. Didn't clean the VGA block though - afraid to void the warranty, and I haven't seen this stuff show up anywhere else. Plus it still has excellent thermal performance. I wish my CPU kept as cool.

For the life of me I couldn't notice a difference between the old and new pumps, except in how they spin - new one spins freely, old one grinds and wobbles each revolution.

Anyone know about the warranty support for these things? Tried firing off an e-mail to FrozenCPU (where I bought both pumps).
 
Take a picture of the ceramic bearing on the pump (the little white ball the impeller housing sits on). I'd wager you had air in there, and without water, the bearing will wear exceptionally fast.

** And about your VGA block, opening it up does not void any warranty. All that sticker EK puts on there means is that it passed an air pressure leak test at the "factory", so it's guaranteed not to leak from the block o-ring area out of the box.
