Removing the pump from the EK unit will not void any warrantys
This might be wrong, and its hard to find accurate info on it, but I don't think an EK DDC 3.2 PWM and a 35X are the same things.
The EK is meant to be a PWM controlled DDC 3.2. If you look at the pump performance of a DDC3.25 with an aftermaket high flow top
they max out at about the 18W of the specs.
While a 35X
can go all the way to 24W and even higher.
I can't understand how just PWM control would allow a pump to use that much more power at max. Maybe the EK version would do the same but maybe the 35X has a different speed and power limit control.
The EK pump lists max head specs higher than the 35X so maybe it is the same thing? They also seem have the same Laing model name.
It seems like all the different brands that sell rebranded Laing pumps often use specs from Laing that cover a range of pumps like the D5 series and the DDC series rather than accurate specs for the version they are selling.
eg. Swiftech list the same specs for both the 655 and the 655-B even though they are very different.
Either way you are better off saving the money rather than buying a pump with a top you won't use. Unless you want to keep it as a spare or something.Edited by Jakusonfire - 9/19/13 at 8:18pm
