Lexicon RV-8 query followup-fan noise?

Ok. This was a dud when i bought it secondhand, So ive never actually heard it. Eventually had to get a new power supply from lexicon, at ridiculous cost. (Approx USD700, shipped to NZ, of which person who sold amp to me contributed half). Amp is now up and running. But fan noise from the power supply seems LOUD to me, and is constant, even staying on for ages after you power the unit down. Can anyone who has owned one of these amps tell me-Is this fan noise normal, and im being over sensitive?!

Between this, and the fan on my linn sizmik subwoofer, and in my oppo bdp 95, im going nuts. Whose bright idea was to use fans to cool hifi and HT gear, anyway?! Is it just me? But meeb theres something wrong with lexicon? At least the linn and oppo fans are only on intermittently.....

If the fans bother you that much, I would try and swap them out with some silent computer fans. You just have to make sure you pick ones that fit where you need them.

Also, check the RV-8 over and make sure none of the air vents are blocked with anything. That could cause the fan to run more.

Try checking the owners manual as well. You may be able to adjust the fan settings right in the menu system.

Yep thanks but i cant find any good, quiet 80mmx80mmx15mm (or more like 13mm, with NO headroom) 24v fans...

No settings in rv8 to change fan speeds; it should all be automatic, according to service manual.

I left the amp on standby all night, and the fan was STILL running at full speed this morning, so im thinking there must be something wrong here...can anyone confirm who has owned the RV8 before?

Many thanks in advance

Thanks, but 40db!!! Was looking more for the 14-20db area. Or even better, any advice from rv8 owners as to whether this is normal for the power supply fan (which has just been replaced, along with the power supply) to be running on full tilt permanently, even on standby....?
