The Laing D4 Basic is
Rated voltage: 12 V DC direct current
Power input: 17 W
Will be fine for cooling your cpu![]()
D4 is basically not as good as the D5, known to have a noticeable hum, doesn't have the variable speed control and if I remember correctly isn't as powerful as D5.
It'll be a perfectly ok pump though for any setup.
It is not a DDC pump by the way.
