Hi all 
thx for read the thread.
I have new watercooling system and i use the mcp600 rev2 for pump, but is too small for the system.
My system is that:
Pump <(2Radiators Cooltek double)> Black ice extreme 3 -> Storm G4 -> DD maze4 VGA -> DD Chipset -> Innovatek tank o matik.
I have a little site in my box(lian li v1000), i have only 10cmx24cm for pump. And i can't buy one pump more expensive than 120€(135$ aprox).
I see a iwaki md20 and aqua medic OC 3500 but i am not sure what is better :shrug: , other people said me than buy one more mcp600 rev2 or buy 2 D4. What do you thing?
Thx for your reply and for your time.
