How did the 350 not work for you? the 650 has more free flow but the head on the 350 is a little higher, I believe that they are more or less the same when you consder the strain a normal system puts on the pump.

There won't be a big difference. The 350 is an excellent pump, why spend money for a minimal performance gain. With your setup I rather get another/bigger radiator.

the 350 quit working , So I needed to replace it. I thought this pump would handle a bigger Rad with no problem.

[Fairydust]

It quit working? Start Problems, or did you destroy that fine piece of german engineering? You ran distilled water wihtout glycol additive?

Anyway, if you do need a new pump, the mcp650/d4 is quite capable, although not as quiet as the mcp 350/ddc.

Unless you modded it, return the 350. Some of them had start problems, but it will be replaced and the newer ones I believe are fine.

The very first batch of pumps was having startup problems caused by having a 4+ A current requirement for proper startup (0.8 A at 12v during operation).

Yeah most the DDC/350 i've seen with start problems, were running without lubricating additive like ethylene glycol and the like. Once people mixed some corrossion protection/antifreeze/lubricant combo in their water, the problems disappeared. Few cases were caused by using small AC adapters that couldn't supply enough power for startup.

I had one that had an issue where it often failed to start, it is a known problem, and easy to RMA. I was able to do an advanced RMA directly to Swiftech.

Some of them have problems where they quit working after a short while. contact swiftech and they will handle the RMA for you. No need to spend money on something that wasnt your fault.

I was running a mixture of distilled and water wetter and a splash of bleach
Tried everything I could to get it to run. I'm in RMA process right now.Needed to get the computer up and running. Ill end up with a extra pump in the parts cabinet.

Bleach? :nono:

[MaxxxRacer]

bleach = bad. thats a no no.
