If the fan just started being noisy, that would be a really bad idea, as the fan _will_ fail sometime soon. A better solution in that case would be to just buy a new fan (although they are not the easiest ones to find.) Any fan controller should work, however, as the fans are just regular ones that are ~60mm (at least on the two 3Com switches I have opened up.) You may have to do some hacking and slashing to get it in there, and you may need one capable of controllng two, as some of those 3Com switches have two fans in them. The good news is that there is usually plenty of free space inside the box to play around with, just be careful not to obstruct the air flow. One more thing to note: The fans are usually mounted right between the power supply and the rest of the circuitry, and although it looks like they are just used to cool the power supply, those other chips get mighty warm sometimes.
