Choosing the right pump

post #1 of 5
Thread Starter 
I am a first time water cooler here and would like some advice on a couple of pumps.

Swiftech MCP655 or Swiftech MCP35X.

So far this is how my loop is planned: XSPC RAYSTORM CPU block for AMD 8320, EK full coverage water block for 7950, Alphacool NexXxoS XT45 Full Copper 360mm radiator, 1/2" ID tubing, XSPC Single Bay Reservoir 5.25", I may in the near future put an additional rad in the loop depending on how well it performs.

Which pump will serve me better?

How does the parts list look? Any possible changes?

Thanks for any input. cheers.gif

Either pump will handle that loop without a problem. You would probably have to turn the 35x down from full speed so it doesn;t get to hot a burn out. The 655 is also a bit quieter at full speed than the 35x. At least to my ears anyway

Does the 655 have an issue with burning out like the 35x does?

I have seen heatsinks for the 35x to help prevent burn outs. Are these heatsinks necessary for the 655?

A few people start misinforming others, then everyone turns rumor into fact.

Mcp 35x don't just BURN OUT.. Sure they had issues in the past, they re-worked the pump since then.

The pump CAN get hot. Also, theres no reason to run it on 100%speed unless you have a serious amount of restriction. This is the big reason for those pumps burning out, people running 4500rpm with barely any restriction and no heatsink. it's more of user error. I'ts like putting a radeon r9 290x in a case with no fans or ventilation and blaming the card for burning out and what not.
Some people will mention how you have to buy a HSF to make the mcp35x "safe", you don't NEED to but it's probably the wiser thing to do. A mcp655 would need an aftermarket top for the added performance anyway and still wouldn't compete with the mcp35x biggrin.gif both have proc's and con's , both do better when buying things that don't come with just the pump. MCP655 is pretty huge compared to a MCP35x also

The heatsink and fan combo makes the pump virtually run as cool as possible, and any other air flow in case helps.

The d5 cools itself with the water inside, so the heat is dumped into the loop versus where the mcp35x doesn't. Sure negligible amounts, but if you are like me, a rad between blocks, fans at a certain rpm, all those things start adding up and 1C here 1C there next thing you know you have -5C off core temps and -2C off water temp tongue.gif

They are both great pumps, mcp35x beats it in performance hands down though. Only thing to consider is the noise where mcp35x at max speed has a high pitch noise to it and d5's have more of a low pitched buzz(depending where mounted and what not? )

All of this. Ever single word.
