Peltier vs Waterpump

I am planning to get watercooling plus either a 172" or 220W peltier. I am wondering, will I be able to use the Eheim 1048 or will I need the more powerful 1250 to cool that sucker - More flow rate/pressure = better cooling.

Using a DangerDen maze 3-1 and 1/2" tubing, that is.

you could use a 1048 but there better be hardly ANY restrictions. I mean not even more than 6" of head. i would go with a 1250 MINimium for a 220 tec.

oh well, I'l just have to pay the extra £10 for the 1250 then - no sense getting WCing with no flow...
