Is may pump about to die or was this a freak incident? Zalman Reserator 1+

[jhbodle]

I installed a new Zalman Reserator 1+ on my PC last October using the Zalman coolant and it's been perfect until today. However...

...Yesterday I upgraded the CPU from an Atholn 62 X2 3800+ to an Opteron 185 2.6GHz. I then overclocked it to 2.86GHz using the default voltage. Everything seemed fine until I ran the Orthos stress test. Everything was fine for an hour until the PC shut down. I switched it back on and the PC shut down after a few seconds.

The pump was not pumping any water any more. Switching the reserator off at the wall socket and back on again didn't help. After an hour the pump kicked back into life again all by itself.

So what happened here? Do water pumps have a protection feature which shuts them down if the water temperature gets too high? Do I need a new pump? If so what should I get - I really want the new pump to fit inside the reserator, or is this not possible?

I've installed the Zalman Reserator fan kit now to see if that helps. I can't check the CPU temp because the motherboard temp sensors broke when I installed my old Vapochill on it and now the reading is stuck at -55C. Any help appreciated, I don't want my new opty to fry!

best to dump the pump an get D5 (http://www.dangerden.com/store/product.php?productid=175) for your currrent unit can't handle the heat an seizes up

Of you could get the MCP355 since its smaller and already set for 3/8 tubing

Thanks guys. Can either of those pumps be a direct replacement for the existing pump? For example will they fit in the base of the Reserator like the current pump or do I have to do something else to get them to fit? And do they work on 240 volts like the zalman pump?

no, you have a problem there. I doubt that you be able to mount one of those pumps in the Zalman tower. the pther posters didn;t realize what you were asking. All those pumps are DC, not AC. And they are meant to be mounted inside your PC. As far as what will work as a direct replacement, have no idea.

I'm not even sure if you could switch over to a internal DC pump, with the fittings like thye are on the Zalman. If you could remove the exsiting pump, somehow reconnect the fittings using a DC pump like the ones mentioned, you could do it. Other than that, you might want to check with Zalman and see what they have as a replacement.

I have the reserator II, it uses the same ehim pump as the reserator I. Its basically a common fish tank pump and costs like 10.00 at an aquarium store. The zalman tubing is standard 8/10 mm tubing which is close to 3/8" tubing. It fits snug on 3/8" barbs. You could put an internal DC pump in and forget about the reserator pump but then you loose all the coolness of the Zalman.

You can order a replacement pump, I have seen them for sale at multiple e-tailers...

But honestly I would sell it, and build from scratch.. I dont even have to begin to tell you why... this is XS !

Lol I know i've gone all wussy over the past few months - I used to have a Vapochill on there but the maintenance got too much for me. It always had a problem so I thought i'd change to water cooling. I fancied the most powerful silent system I could find so I got me 2 7950GTs with heatpipe cooling and the zalman reserator. Even the PSU is fanless. I've been very happy with the silence but it looks like my new Opteron at 2.86GHz was too much for it!

Some people are saying that a one of these pumps will be a direct replacement but with more flow:

Are they correct?

open res an remove pump (http://www.zalman.co.kr/images/product_img/cooling/reserator102s.jpg) then thread the input for a copper tube to reach other end of res with 1/2 clearance. install pump on the output of res tower. mcp355 is good selection 3/8 fittings to match zulman tubing, for OC'ing then just get a pump and rad 3x120mm fan unit

The only replacement pumps I have seen were branded by Zalman, and not owning one personally, I cant verify...:rolleyes:

Remove the pump, add some hose to the inlet (return flow) to the res, use a DDC and have the DDC within the pc case. It's be so much better. have the res near an open window as well or an ac unit

Is this what you're looking for?

http://www.alphacool.de/product_info.php/products_id/661/cPath/5_26_28/eheim-pumps/eheim-compact-pump-600-230-volt:.html

It's a compact submersible pump that runs off mains voltage. If you look in the same section, they have a 120V version if you have '110 volt mains'.
