Pioneer VSX-41

[Kelly C]

Hey all,

I just replaced a couple of caps on a Pioneer VSX-41 that I picked up for free. Now it sounds great, but the cooling fan is not running. Does anyone know if it is supposed to run full-time, or is there a heat threshold that needs to be reached before it is activated?

Thanks in advance!

I believe, on an Onkyo there is 60 C threshold. Maybe the Pioneer works in a similar way.
On the Onkyo, there is an empty connector and I have transferred the fan there, to run constantly.

Thanks, I hope so. This model doesn't have a bottom access panel, so I pretty much had to clear the entire case to get at these caps. I don't relish the thought of having to do it again.

In my opinion, the 60C is way to hot. I can barely hold my hands on the top of the case. Heat dries out capacitors and can cause other problems.
I rather have a fan running all the time, then having issues in a year or two.
On another Onkyo, which did not have a fan build in, I have made a power USB harness(only + and -) and plugged it in, into my TV and I'm using a laptop cooler on top of the receiver. It would turn on and off with the TV. TV's USB port, turns off the power after a little while, not instantly.

The fan is electronicaly controled So it looks like it only comes on when needed.

Thanks for the responses. It certainly does create a good deal of heat, may have contributed to the cap failure. There was not a brand marking on the ones I replaced. I will look into a permanent cooling solution.

Can I see the bottom of the unit? Some of these Pioneer have perforate bottom cover that you need to nip off the fingers to remove the bottom cover, it was made like that for servicing.

For the manual search for VSX-D811

Re: Pioneer VSX-41

This one doesn't seem to be designed that way. The perforations are under the fan and heat sink, not the board.

Nope, not made for easy repair.

Re: Pioneer VSX-41

Otherwise, very pleased with the look and sound. And the price was right. Again, big thanks to all who help out on this forum!
