Fan failure

I had both fans on my MacBook Pro die last summer. Since I was out of warranty I replaced them myself (keeping in mind I was clipping resistors on Mac Plus motherboards to upgrade to a full 4 MB some 20 yrs ago). It was a simple replacement, all turned out nicely. I upgraded to Leopard, not that I'm blaming Leopard for more issues than it already had, but shortly after the upgrade the right fan started 'talking' to me, i.e., chattering. I found a fan control program that's compatible with Leopard and installed it. Both were still working when I recently installed a hard drive upgrade but the right one died shortly after. I'm thinking there's some issue here as finding a right fan seems to be nearly impossible. Anyone have any idea how to prevent another fan failure?

Macbookpro 15, Mac OS X (10.5), 1.5 GB RAM

I am having the same problem with the right fan on MBP15. Even though the RPM runs low at 995 it still rattles regardless on temperature and RPM speed. Once in a while when it becomes rattled, I lift the MBP15 and hit the bottom of the laptop on the right side to stop the fan from rattling. It will stop for awhile then it will rattles again. It's becoming annoying. Does this mean the fan is loose that needs tighten up or replacement? I've installed iStatPro widget to monitor the temperature and fan. Everything looks good except the annoying rattles. Any advice?
