Hi there, i currently have an Ehiem 1250 but would like a an internally powered pump ideally. My loop is pretty simple, a thermochill PA120.2, cascade g5 waterblock, 1/2" Aquatube Res, dangerden Maze 4 GPU.

I know the Liang pumps seem to be the best but which one? the d5? the DDC is confusing as there seem to be a lot of different revisions and top combinations. price isnt really a factor but i would like it to be at least as quiet as the 1250 if thats possible?

cheers for any help
 
I would say to go for the D5, less of a failure rate than the DDC, but the DDC does look nicer and is slightly quieter than the D5.

DDC with any after market top of your choice, the difference in performance is marginal. Either or will be an improvement over the Eheim. Better temperatures and lower noise.
 
^^ Agree

Only two choices tbh , and i,ve got both running in my case.

I would go for the D5 ,totally silent on a bit of foam , the DDC 18W gives out a bit of a buzzing noise if you get really close to it.

Both excellent pumps.

surely the ddc cant be that bad for failure rates??? what happens to them, do they die just randomly :confused:
 
Had a DCC die on me on my cpu loop in my watercooling setup,lucky it was a intel cpu as they shut down when they get to hot.

Replaced with D5 vario,quiet powerfull and stable pump.
 
I question whether you will see any benefit. 1250s are generally pretty quiet if they're kept clean and although the Cascade is restrictive I'd be surprised if the extra head of a Laing would make much of a difference temperature-wise.

Of course, the D5 would be a fair bit smaller and might allow for a different tube lay-out. If you do swap the Eheim for a Laing, try to make no other changes to isolate the single change in order to prove any difference is purely caused by the pump.
 
I quite liked my D5 vario, was quiet even on full power with my 3 block (cpu, gpu, nbridge) loop + 120.2.

Just so happens its going spare too since I'm going back to air cooling on my new build :)

Been thinking the same thing myself. I'm running the same Eheim 1250 & Storm G5 combo, and despite being tempted to get a newer D5 & Fusion combo I can't see it's worth it until I go quad-core (the G5 beats the Fusion on dual-core and the silver in the G5 stops any issues with micro-organisms taking up home in my loop allowing me to us filtered tap water).

My Eheim sits outside the case on a couple of foam backed scouring pads (high tech solution I know), which absorb any vibration and leave the pump virtually silent, while allowing heat to dissipate outside the case.

It's also a lot easier to leave the pump on after the PC has shut down to cool down the water further, or leak test a new install.
 
I still use one inside a PC60 lying on its side in the bottom of the 5¼" bays resting on some samples of Tempur foam from the Furniture Village. And I have another one spare if I ever need it. I'm still using a BIX; why not? My E6600 is under a GTX and I'm sure it could be cooler but who cares? It's at 3300 and works well.

One thing with an Eheim; it will last you for a long long time.
