MCP655 - B how to make variable?

post #1 of 9
Thread Starter 
I run my MCP655-Variable at level 3 usually ... I can get a MCP655-B for 50 bucks ... I am curious if I can run the -B, no variable at certain speeds, so it's the same as the variable?

Can I match voltages or something?

I've got the non-variable type and it is virtually silent at full speed, so I wouldn't worry about it.

but in case it is not ... any way to turn it down, to match a level of the MCP655-variable?

I assume running at different speeds is bad.

As long as you have a properly bled out loop and the pump isn't vibrating against your computer tower, you won't hear it.

I haven't installed mine yet ... I heard they're completely silent at 3/4 speed, but audible around 5.

You can undervolt it with a good fan controller or pumps speed controller no problem. Just don't expect to reach Level 5 vario by overvolting it...unfortunately that doesn't help. It is stuck at setting 4, but could be lowered with lower voltage to about 8V or so.

If it's stuck at 4 ... perfect i'll just put my variable at level 4.

How do you know it's level 4?

Can anyone verify for me that the -B is indeed speed 4 for the Variable, I don't want to cause issues with my Variable pump MCP655.

EDIT :

looks like it is compared to speed setting 4 on my variable.
