Zalman RC56 Resistor and Fans

kogase · Post by **kogase** » Thu Oct 21, 2004 12:42 pm

I have a few Zalman quite mode adaptors, and I'm wondering whether they can be used with other fans I'm buying and produce a similar result. A site that sells them (quietpc.com) says that they reduce voltage from 12 to 7, but I've read posts here that say they do different things for different fans. I'm buying a Panaflo M1A to cool my CPU, and am hoping that the Zalman resistors will do the job for it. Will they?

Note: I know everyone's solution to everything is: "just buy a fanmate". But I'm not going to do that.

Why not?

A Fanmate'll let you fine-tune the fan speed to wherever you want. With the RC-56's, you have to live with whatever it gives you.

Because I don't feel like buying yet another item for this or that. At least, not until I find out if these resistors will work fine for what I want.

OK, then try it out once your M1A arrives. Your own ears are the best judge anyway.

They will work. There are different versions of them. I'm trying to find a color chart now.

They work, but the lower amperage the fans use, the less the slowdown/voltage drop. You should be able to use multiple RC56's on a lot of fans. You can also replace the resistor with a different one (I recently did so for a broken RC56).

My biggest concern is that apparently the M1A I'm buying (from Newegg) won't have an RPM monitor, so I won't know exactly what's happening.

You're right, it probably won't, but RPM shouldn't really matter anyway. What counts is 1) How loud is it?, and 2) Does it flow enough air to do it's job? I've used non-RPM monitoring Panaflos as my CPU fans for years and never had any issues.
