Anyone used this pump?

XSPC Laing 18W DDC-Pump 12V DDC 3.25 - ULTRA PERFROMANCE - 900lph

I've ordered one, and interested to know how it performs / sounds

My last pump was an EK DCP 4.0 and it didn't seem powerful enough for my watercooling setup. I know that i used too much 1/2"ID tubing, as it was all over the place like spaghetti, but the pump didn't seem to be able to pump the water around enough, i could see that the water wasn't filling the tubing, and consequently temps on the CPU were only on par with an average air cooler
 
If the water isn't filling the tubing, that's your fault for not filling the loop correctly, not the pumps,

The DDC is a pretty good pump by all accounts.
 
I've used a Laing DDC 18W before, very powerful but also noisy due to vibrations so install it on top of some foam to help silence it. A good compromise is the 10W version, it's much quieter but still powerful enough for most loops.

EDIT: sounds like you didn't bleed your last loop properly.
 
You guys could very well be right. Are you able to give me some pointers on what i did wrong?

I filled the loop by filling the reservoir once the system is all put together, once the reservoir was filled, i started the system to get the coolant pumped around, and consequently the reservoir started to go down, so i topped it up

Was there another step i was supposed to take? I don't want to make the same mistake again

thanks
 
Generally, you keep filling until only tiny tiny little air bubbles exist, If you have an air block in your loop, you waggle your machine around to free the block and keep filling, a little air in a reservoir is fine, but air in a radiator or block or especially a pump is generally not good for performance and air in a pump can kill it.
 
Yeah sounds like you had either an air lock or just loads of air still circulating the system, the remedy for either situation is to shake the case around (obviously watch for leaks!) and also try pinching the tubing for a second or two, this builds up some pressure which helps to move any air in the loop.
You could also try turning the pump on and off several times, but always make sure the pump is being fed coolant, do not run the pump dry!
 
Too much tubing makes it harder to get air out.

The pump you ordered is only 100lph more than the EK pump. The EK pump is easily good enough to run loops with at least 3 high flow blocks. I very much doubt the pump is your problem and so you wont find any performance gain from this new one. If your temperatures are lacking it could be air trapped in blocks or radiators, lack of powerful fans on the radiators or bad contact between the blocks and what you are cooling (could be too much TIC or it wasn't cleaned properly)

Check to see if your hosing near the block is warm under load and if your radiator is roughly the same. If your block is warm but radiator is cold, likely you have bad water flow due to air. If your block is not very warm but your CPU temp is high, likely you have bad contact between the block and CPU. If your whole loop is warm and temps are bad, it is likely the fans attached to radiators aren't enough or you don't have enough radiator.
