My Swiftech Maelstrom is dead, help me chose a replacement!

post #1 of 6
Thread Starter 
Good day Overclockers


So I have been using the Maelstrom with 2 pumps configuration for a long time (more than 2 years), one day I decided to turn my PC off ( I usually don't turn it off ) and after 30 min. I decided to turn it on to download some stuff but the pumps won't turn on at all, Decided to try them out with another PSU and again they wont turn on!!!!!

I am surprised *** just happened I thought redundancy means that one should work or at least both pumps should not fail together, the pumps are both connected on the same Cable from the PSU with one fan, the fan is fine and spins as soon as I turn on the pc but not the pumps !

Any way seems that the pumps are dead and I am thinking should I get another Maelstrom system or try out Koolance dual D5 res/pump combo or maybe the EK dual DDC 3.2 Res combo or the XSPC dual D5 res combo!

Need your advise biggrin.gif

i forgot to add that I use 3 EK R9 290X WATER BLOCKS and 1 CPU block also from ek, 2x480 rads inside a little devil case.

Koolance RP-452X2 rev 2.0 dual D5s. Quiet, versatile (serial/parallel) and very well made.
The only thing I don't like about it is the U shaped pipe used to bridge both pumps in serial.

I have the EK dual DDC 3.2 res/pump combo too but that's in an ongoing build.

Thx for the reply, so you haven't tested the EK combo yet ?

I heard that the Koolance is hard to bleed, in my experience with bay pump/reservoir combos they are all hard to bleed how is the koolance any different?
Also the U shaped pipe, you do not like it because of the way it looks or is there any other thing ?

Nope, my build has halted as I am in the midst of switching from acrylic tubing to copper.

I have the RP-452X2 in my 900D with a 480 up top and a 480 + 240 below and it's actually not that hard to bleed.

How I do it:
- Remove the 2 top facing stop plugs
- Fill the reservoir three-quarters full
- Power the pumps momentarily to fill the loop
- Some of the coolant will return to the reservoir (backwash). Just tilt your system upwards (with the front of the reservoir facing you) about 45 to 60 degrees to get the coolant back in the loop. Do it slowly so the coolant doesn't run out of the 2 fill ports on top.
- Lather, rinse, repeat

It took about 3 days for most of the air to bleed out and I had to top up the reservoir a couple of times.
It also helps if you tilt your system to the side and let it run for a couple of minutes (with the stop plugs on).

About the U shaped tube, it just looks strange to me. They could have made a delrin block with a channel to bridge the inlet/outlet (sort of like an EK-FC Bridge).

I have owned the 452x2 in ver 1.3 and 2.0. The 2.0 is miles and miles better than the 1.3. I was a big fan of the 2.0, it was just so versatile and so well made with all the intricate plumbing and thick aluminium face plate.

Bleeding it was not hard at all once you get a feel for it, though set in dual series with the connector piece is always harder because you have to get air out of both pumps. I would fill the res sections and tip the whole system all the way on its back so it was facing straight up, then shake it side to side til bubbles start appearing in the res from out of the pumps. Then tip it back down and back up a few times while adding water to top up. Doing this I could get a fair bit of water into the loop and all the air out of the pumps before even powering the pumps. Once I was convinced the air was out of the first pump I would power it and just use it to fill the loop, only powering the second pump after I felt like it was mostly full.
With some practice this took hardly any time at all.
