Pump confusion...

rb1985 · 26 Mar 2014 at 21:29

Last on the shopping list is pump.

I've read that higher head ratings are better for long length loops. Is this the case?

Out of the 2 below which would be better for a loop of CPU and 2x GPU with a 240 and a 480 rad with longer than average tubing?

YOUR BASKET
1 x EK Water Blocks EK-D5 Vario X-TOP - Plexi (incl. pump) £89.99
1 x EK Water Blocks EK-DDC 3.25 X-TOP CSQ - Plexi £71.99
Total : £171.58 (includes shipping : £8.00).

Thankyou muchly

id go for the D5 personally.

but either should be fine tbh

Depends on your definition of 'longer than average'. But 9/10 times I'd chose the D5 over the DDC, mainly for silence.

EK DCP 4.0 Pump (12v)£39 with a 3pin Voltage Adaptor Cable 12V -> 9.5V £2 to reduce noise, will have no problems couping with your set up.

See sig > using a EK DCP 4.0 Pump (12v) with a 3pin Voltage Adaptor Cable 12V -> 9.5V to reduce pump noise my self and it has not effected my temps at all.

My rad 560 is external so l would say my loop is longer than average and even more my sons build CPU 930:4.0GHz+GPU 6970+420 rad > H2o cooled.

As the tube coming out and back in to his case both are 1mtr in length from his external rad and he is using the EK DCP 2.2 Pump (12v) 3pin Voltage Adaptor Cable.

The higher head comes into play with VERY long loops. I am talking about external loops which have 3/4 of meters of tubing or loops with many high restriction blocks. I would count a three high flow block loop with a few radiators as being fairly average in size and either pump will do the trick. Personally out of those choices I would go for the DDC with a pump top, as that DCC has insane spec. Would choose the D5 if noise or if you are open to reservoir combo's, as there is more choice.

OLDPHART's recommendation should also be thought about, as the 4.0 offers a good lower budget solution which is just as capable. I currently have two next to me on fan controllers working silently running a 5 block loop with two radiators. I can switch one off and get away with just a single 4.0 on full power but it is noisier that way. My two pumps cost about the same as the D5, though you can easily get away with one.

Will say that the DDC you linked has some insane specs though, i am temped to buy one to play about with.
