In the watercooling world you have basically 2 choices. D5 or DDC.
The D5 is bigger, the hole from the pump top is not symetrical (on hole is higher than the other) and it’s making a huming noise.
The DDC, on the other hand, have a high pitch noise, the hole is symmetrical (both have the same height) and it’s smaller.
Personally, I tried both of them and I prefer the DDC because it’s smaller.
both pumps at low speed will be barely noticeable, but I think the DDC is a lot more annoying at full speed (I’m never running my pump at full speed anyway, 25% is enough for me)
pick your weapon.
Using this pump in the office computer for 5 years, still goes strong!

Using this pump at a low speed, around 20-25% to power my dual 240mm radiator setup in my FormD T1, with two 240 rads in a 9.5L case its a very very tight fit but there is space for this pump and it pushes water like no tomorrow. Very quiet too when running at this speed. 100% would recommend.
