power used by just the fan in a power supply?
I heard at a HPC presentation that the fan in the power supply of a 1U server
"pizza box" can draw 15-20 W! I looked up the specs of some 40 mm case fans used to cool CPU, DIMMs etc and they were in the range 4 W to 13 W. So I suppose 15 W is plausible. On the other hand, the larger case fans in a desktop PC need only 1 to 2 W. So would it be reasonable to assume that in a desktop power supply, the fan is roughly 2 W draw also? |

It should have the power rating printed on the hub. My Vantec Stealth in the kitchen says 1.2W on it. 12V @ 0.1A. That's roughly the class of fan inside an average power supply. I had already looked at 3 PCs before my original post. One, an Antec only has some numbers that look like a date. The other 2 power supplies (Coolermaster and Chinesium) have no sticker on the fan hubs. |

Failed Antec True330 Bottom fan: 12V @ 0.25A 92mm square Rear fan: 12V @ 0.20A 80mm square Both have labels on the hub, inside. Paul I have a couple Enermax, one with 12V @ 0.17A showing on the 80mm fan label on the back. The other has a 12V @ 0.26A fan. I can't see the details on the other fans on those. Paul |
