Update: Poweredge 2950 III Fan Mod-Day013 Uptime

Server Status:
POST Issues-None [boot up straight to W2012]
F1 Fan Failure Error-None
CPU Error-None
Memory Error-None
Hard Drive Error-None
Current Rack Temperature; 82’F
Thermostat Setting: 79’F
RunTime: Day013, [Since 20130823, 24/7 operation]
Noise Level: I think an electric fan is louder than the Poweredge 2950. 

ISSUES:
1. Electrical Consumption is $0.73 per day or $22.01 per month.  I have to migrate my old old Hyper-V server to this server to save electricity.
2. Need more time on the server.  Got the Hyper-V 2012 and Sharepoint 2013 running. Next is Exchange and Lync.  Still need to read more books.

PROBLEM: Dell Poweredge 2950 III Jet Engine Fan Noise

PROBLEM: Dell Poweredge 2950 III Jet Engine Fan Noise
FIX: Install a 47 ohms resistor on Fan1,2,3,4 and Power Supply fan
OBJECTIVE: To reduce the fan noise of Poweredge 2950 III without overheating the CPU
STATUS: Completed
QUESTIONS:
How noisy after the mod? I can stay and work in my office all day without being bothered by the noise.
How hot is the server? Tjmax is 100’C
What’s the Server Rack Ambient Temperature? 86’F
What is the Server Room temperature? 80’F
What is the house thermostat setting? 76’F
How much was the cost of the mod? $1.49 from Radio Shack
Why use 47 ohms? From my 2007 experiment to reduce the fan noise of a Poweredge 1550.
10v=12 ohms
9v=20 ohms
8v=30 ohms
7v=42 ohms
6.5v=50 ohms [6500 rpm]

Tools/Supplies/Skills Required:
Soldering iron
Heat Shrink
5 pcs. 47 ohms resistor 1/2 watt from Radio Shack p#-2711105
Soldering skills
Patience

Step by Step:
0. Proceed at your own risk.
1. Turn off power
2. Remove cover
3. Remove Fan 1,2,3,4, Figure 1
4. Cut “Red” wire, Figure 2
5. Solder a wire to extend the red wire and heat shrink, Figure 3
6. Repeat Step5 for fan2,3,4
7. Solder a 47 ohms resistor inline with the newly added wire extension and heat shrink it, Figure 5
8. Reinstall fan smartly back to the fan mount.  Smartly-meaning be careful not to let the wire get tangled with the rotating fan or short circuit it to ground, Figure 6
9. Remove 1 Power Supply [modify 1 power supply only, save the other one as a backup just in case this mod will burn it over time]
10. Remove the cover of the power supply [smartly], you can figured it out.
11. Remove fan from the power supply, Figure 10
12. Cut “Red” wire, Figure 11
13. Solder a wire to extend the red wire and heat shrink
13. Solder a 47 ohms resistor inline with the newly added wire extension and heat shrink it, Figure 12
14. Reinstall fan smartly back to the fan mount.  Smartly-meaning be careful not to let the wire get tangled with the rotating fan or short circuit it to ground.
15. Replace the power supply cover [smartly], it needs some thinking but you can use the other spare power supply as a visual aid of how the assembly should be.
16. Reinsert power supply back to the server
17. Turn on server
18. Monitor server temperature
19. Verify server temperature at the back

What’s next? “Off the Grid” Solar Power.  This Poweredge 2950  is rated 780 watts.
780 watts/1000 kw = .78kw
.78kw x 24 hours = 18.72 kWh/day
18.72 kWh/day x $0.10/kWh=$1.87 cost per day
$1.87 x 30 days=$56.1 cost per month
$56.1 x12 months=$673.2 cost per year
