Also among today's UPS deliveries...was the RFE'd CPU fan for my Dell Dimension XPS (Gen 2) named "TARDIS". (my Windows laptop was named "SIDRAT")....though I been reusing the names on other devices lately.

Namely, the Time Machine partition at work is called "LKC SIDRAT" (the Mac is named "LKC"), and the Time Machine partition at home is called "LKC TARDIS". Not sure the naming is as accurate. The work drive is a 2.5" 100GB 7200rpm drive, while the home drive is a 2.5" 160GB 5400rpm drive.

Anyways...CPU fan installed, and the computer is back up and running. While without the CPU fan...the other CPU fan was running ~2400rpm (up from its normal <900rpm) and the CPU temperature in the upper 60's....Celsius. Now I have BOINC running full out and the CPU temperature is reading 52.... the new fan is showing ~2500rpm and the remaining original fan is ~1700rpm.

Put BOINC back to preferences....things should gradually drop back. Not sure if the old fan will go under 1000rpm again. It had always been a bit weird on what speed it would run at....seems unless it breaks 1000, it stay below...leaving the Fan 1 to do most of the work.

Though it is strange that the lower CPU fan is the one that works harder than the higher CPU fan. There's probably something about the fan shroud that makes most of the air over the CPU heatsink pull down across it.
