Quiet Fan plug-and-play modification
Is the SV8000 version 2 fan driving you crazy with noise? Are you having to turn the power switch off in the back? Then this modification is for you.

Here is the quiet fan modification I did. This is a plug-and-play modification. No cutting of wires or soldiering. You can also easily revert back to a stock OEM receiver if needed for warranty work. This modification costs about $18. It drops the noise level from about 30 dBA (noisy stock OEM) to about 10dBA (whisper quiet).

I can now leave the power switch in the back on all the time, and it is very quiet. You can put your ear right up to the unit and can't hear it. It also pulls a lot of air through the unit. I think this fan even pulls more cfm of air through the unit than the stock fan. The unit is very cool, and it is left powered on all the time.

#1: Buy a SilenX fan (40mm X 10mm) and a SilenX fan speed controller.

#2: Remove the 5-volt OEM fan and unplug from the 5-volt connector.

#3: Install the new SilenX fan. Use the silicon plugs included instead of metal screws. This cuts down on case vibration noise.

#4: Install the Fan Controller. Plug the SilenX fan into the Fan Controller.

#5: Unplug the 12-volt 4-pin molex connector from the 8psk module. Plug the 4-pin adapter between the original connector and the 8psk module. This is so the Silenx fan gets power in-line from the original connector and the 8psk module. The Silenx fan is a 12-volt fan, not a 5-volt fan like the OEM fan. You can't connect it to the 5-volt connector the OEM fan plugs into. You have to put it in-line with the 12-volt connector. This is better, because a 12-volt fan is quieter than a 5-volt fan.

#6: This is the final installation. The in-line 12-volt connector, to the fan controller, to the SilenX fan.

The last step is to turn down the fan speed slightly. The Silex is 14 dBA at full power (3,500 rpm). Getting that last few hundred rpm really makes the fan put out more noise. If you slightly turn the speed down to about 3,000 rpm the noise cuts down to about 10 dBA and pulls just about as much air. You can fine tune this fan controller to where you feel is best for your situation.

Here's my add on to a V1 using a Silenx IXP-34-08. The fan is 60mm and fits perfectly between the top and bottom of the chassis with a dab of silicon to secure it. It's rated at 8 dba and produces 10cfm.

This mod can also be used in the V2 by removing the 40mm factory fan and unplugging it.

here we go.this was done upo with the new A-1 board installed.so you can get your 12v connection guys.

V2, A-1, Silenx update
I just received a new SV-HD8000 (V2) and A-1 board, so I have some updated pics, and information.
The factory fan with the V2 I got was not that loud running at all, but also produced very,very little air flow, so I decided to install the spare Silenx IXP-34-08 I had on hand.

I removed and unplugged the factory fan and installed the Silenx as shown using 2 small Grey wire nuts on the Yellow (+), and Black (-) wires on the A-1 power cord supplied with the A-1. The power cord is not excessively long, so if you make a wire stripping error, you may need additional wire nuts and wire,lol. The Silenx fan wires are not color coded (3 wire cable), but figured out the center conductor was the 12V (+), and took a guess on the (-) wire and it was a correct guess to produce air flow from the correct direction.

Heat from the power supply board is non existent. There is warm air coming from from the A-1 side, but the top case is barely warm to the to the touch. The A-1 appears to produce as much or more heat than the original 8PSK I installed in my V1, but this fan is doing a great job, and I'm happy with the result. If you have questions, please ask them in the forum.
The first Pic is the V1. The next 4 are the V2
