Michael, thanks for the part number. >May I ask what vendor you sourced >them from?
Would the same fan fit my R7603's?
I found these as NOS on E-Bay. I have No idea if they will fit the 7603 Rack mount. But I am thinking that they might just work. I have never seen inside a R7603, but looking at the manual the illustration appears very similar to the RTM506 fan.
