Replacement of the power supply fans for the T1 Power Supply, T2 Power Supply, as well as an additional power supply in rack 1A was completed this morning.  The boxes were blown out with air to remove dirt and dust.  The inside of all boxes were inspected and no evidence of melting or burning was found. 

After installation the output voltage was measured for each power supply using a multimiter on first the DC setting, then on the AC setting to check for fluctuation (as recommended by Erwin Klassen).  Results below: 

T1 Power Supply:  24.2V DC, 0.001V AC 
T2 Power Supply: 23.6V DC, 0.002V AC 
Other Power Supply: 24.2V DC, 0.004V AC 

The fans are all running properly, the power supplies are cool to the touch, and the T1 and T2 cooling packages are up and running.
