View Full Version : benefits of adding another mcp600 in my loop?

Hi guys,

I read a few places of adding 2 mcp600's in series to improve performance. How much performance gains are we talking about?

if you add it in series, you'll add more pressure head to the loop - which means as the length of tubing increases, the flow will decrease less because there is more pressure pushing the water

more pressure helps in systems with large radiators (eg: mine w/ BIX III), and also with restrictive systems (eg: Cascade, G4, G5 blocks)

Also if you have multiple waterblocks like an NB, GPU, or possibly even a HD block then your system will most probably be more restrictive than most CPU block only loops. With a more restrictive system putting the pumps in serial will indeed probably end up being of benefit.

Downside being unless its really needed most probably you will be adding more heat from the second pump to a loop that really wont benefit all that much from it.

If you want to try getting a little more 'umph' out of your system you could consider trying out overvolting the MCP600 by using a 13.8vdc power supply which you can find online for around $25. According to Cathar's article on pumps this is supposed to yield a definite benefit at the cost of not having the ease of your pump starting every time you start your system. I believe he suggested around a 2 amp/13.8vdc power supply.

ok since I only have one RBX in the loop I think the gains would be minimal so I think I will just keep 1 mcp600.

Can you link me into that article? I want to figure out how to run it at 13.8v as well.

Thanks

yah, you'd be best off just sticking to the single pump

Here is the article I originally read, it heavily influenced my purchase of the MCP600 btw ;)

Cathar's article on popular W/Cing pumps (http://forums.procooling.com/vbb/showthread.php?t=10825)

I found a Tripplite model #PR3 power supply that puts out 13.8vdc at a peak 3amps and sustained 2 amps. If you search around on the internet you can find it for right around $25 + shipping. I was actually surprised and found out I could get it locally for around $28 here in Oklahoma City. Tripplite is certainly not the only manufacturer but they were the first recognized name I turned up in or around the price range I was looking to purchase.

Kudos again to Cathar for that article. Its been extremely helpful and is fairly well written in terms even I could understand ;)

***warning***
Its a rather long article and comes in basically two threads where he does pump vs pump and multi-pump setups.


If ya look at the MCP600 @ 13.8 volts it would appear that your flow will most probably be just about 5% (ballpark) less than using 2 MCP600s at 12 volts. Now the real interesting part is having two MCP600s @ 13.8volts which gives tremendous performance and a nice redundancy in case one poops out. course at that point you are talking about sinking an additional $100 into your system vs $25 for simply upping your voltage to 13.8 volts. Once again I think it pretty much boils down to just how many blocks you have and exactly what you are trying to accomplish with such a susytem. By the time I spent money on two MCP600s and a 13.8 volt power supply I would sincerely be looking into the high head (RD?) series by Iwaki or Panworld/Blueline. Those things are beasts...to the point if I ever did get one I would sincerely consider double clamping my connections just to be safe with the flow rates that would be achieved.....assuming I didnt recreate the 'Sprinkler' effect that some have had.

I didnt have time to look at the whole article yet but is it killing the pump olver-volt it? Will the noise increase at all? I'm just worried about the life of the pump.

If you have any ideas/thoughts please let me hear it.

yea, i have two aquaextrem 50z pumps and i want to know how i can overvolt both of them and will it become louder?
-how much is the pump life shortened?


and what type of psu would i need to overvolt both, cause all of the ones i have seen have only a single output.
-and is there anyway to do it running of the computer powersupply, maybe through some type of invertor or something
thanks
