i prefer the B version cause u can attach the rpm sensor to ur mobo and use any monitor for it so when the pump dies the system will shutdown without damaging anything

Well, my order finally arrived. Its with a friend in another City, but anyways.. He told me my 655-B has the RPM Sensor Wire .
Just wanted to ask, would we be able to control the MCP655-B's RPM through a Software.. Eg. Speedfar or something?

FYI
I just did a max flow rate test on my variable and my non-variable version. I'm going to have to retract my preference because of my results:
That was running 5 tests each to drain and time discharging 3 gallons with one barb into my reservoir and about 20" of 7/16" ID tubing.
Max flow rate variable (Setting max, slightly past 5) = 5.44 GPM
Max flow rate non-variable = 4.94 GPM
That's a 10% diffence on flow, but I should confirm this by testing with some real world loops. If the variable is actually turning the impeller at a higher rpm (which it appears to), pressure head should be higher as well and show similar improvements across the curve.
Going to try a test on the variable at exactly setting 5 and see if it matches my non-variable results, that's the only thing I can think of on the difference because the variable actually goes past 5.

Any luck yet?
Yes, I found the difference between the two pumps, what you don't find anywhere except in Laing's documentation is this:
The D5 Basic model is stuck at setting 4!
Read the top paragraph of laing's brochure on page 4 here:
http://www.lainginc.com/pdf/LTI%20D5...-%206pages.pdf
I didn't run a PQ curve for my basic model, but I did run max head tests with my modified tops.
The D5 variable at setting 5 was around 13.8' and the D5 basic was 11 something, which is consistent with Laing's graphs.
What's frustrating is most watercooling websites give specs for 11' of max head pressure which is much lower than what you get from the variable model. I wish they would identify there is a difference because there really is a significant difference.
The D5 Basic = D5 Vario at Setting 4
sometimes they are worth getting sometimes not depends on how you wanna use em i guess. isn't it the faster they pump the more cool down you get to the cpu. also why would you need 6 pumps are you running some sort of server?
i'm looking at it right now and pictures of it being used but i don't see the sensor anywhere is it like connected to something?
