Would one pump be enough?

Dirk Diggler · 7 Oct 2015 at 08:12

I'm considering a build that will consist of...

Res > D5 pump > 240 rad > CPU > 360 rad > mobo > GPU > 240 rad > GPU.

Will the single D5 pump be enough? I'm really unsure on the limitations of a pump and how to measure that.

This is the pump I have :

Yeah I run 2 480 mm rads, cpu and 2 MOBO blocks on a d5 on speed 1.
Don't bother sticking the rad between the 2 GPU's. It will not make any difference but will make the plumbing much more difficult.

Perfect, cheers.

A D5 is upto the job

Get the PWM version > EK Water Blocks EK-XTOP D5 PWM - Acetal (incl. pump)

What is the GPM flow like on that at such a low speed?

No idea. Why would it matter? it's all about the noise-or lack of... There's about 2ºC between 1 and 5 when benching.

i run 980Ti's in SLI and 5930k cooled with 2x 480 rads and 1x 240mm. I have mine on setting 3 but even changing from setting 2 to setting 5 the difference is not noticeable. 1c maybe. D5's have plenty of flow and wouldnt have an issue with what your looking to cool. As noname has stated if i set to setting 1 i will see a couple degrees difference. Noise isnt an issue for me so i keep mine on setting 3.
