One of the fans in my BV8-40 is very noisy. Is this ambient temperature/humidity related? The fan starts after about 10 minutes use and the noise appears to be coming from the left of centre of the screen looking from the front. There is another fan but that is hardly audible (on all the time). Is this a quality control issue (warranty repair) or a known problem with the chassis which can be sorted with a software update?

I Also had a problem with noisy fans in my BV8 40. But after I updated the DVB-HD software to 0.1.6.6.0 it disapeered. So I would try this first as an easy fix

Alternatively you can reduce fan speed in the service menu.

Worked in mine.

Thanks for the suggestions. DVB is disabled as no signal is available. This perhaps does not affect the fan? The software for DVB HD is 0.1.3.4 . I assume the upgrade to the latest version has to be done by the dealer under warranty?

Regarding the fan settings mine are set to 16 min and 40 max pwm. Could you recommend a speed setting?

Thanks

To correct my earlier post I would estimate the noise starting up around 30 minutes after switch on. Fan 1 & 2 do not vary in RPM when the noise starts so there must be a third fan. I need to find a way to strangle it.

You should be able to update the DVB-HD software yourself with a USB pen. The software can be found at

Thanks Heribert but my settings are identical to yours and have not been changed from new. 

I found reference to the particular fan noise on the German forum:

>>After a while (depending on temperature) you will realize the fan from the DVB-engine. One of the others you can control over the Customer menue in speed and temperature level. I found no way to control the fan for the DVB-engine. Sometimes it does'nt bother me  but in a very quiet environment you notice it<<

I am quite sure my noise is from the DVB engine and not the others which are very quiet. I must try the latest DVB software update as madskp suggested.

Thanks all for the help

For the Mark II version of the Beovision 8 there is a software update to fix a problem where the fan intermittently runs faster than it should.

Build 166d which I think it around version 4.2 is intended to fix this issue.

Thank you Keith,

Will the DVB update not help the problem? Will the Build 166d need to be done by the dealer?
