I had the same issue with a VT 100 MKIII and agree with Rodman as well. I believe the proximity of the fan to the bottom cover was the main problem as the air made noise as it passed through the slots in the cover. You could; detach the fan from the bottom and raise it up a bit, remove the bottom completely and place the fan on the shelf the amp is sitting on, or what I did was to removed the top and bottom covers and disconnected the fan completely. Added bonuses - prevents fan vibrations from affecting the amp and the amp warms up faster. I use a separate fan at the top of the case to extract heat during those long listening sessions - the noise is practically nil. Extracting air is more effective for cooling than blowing air into the case.
ARC VT-200 Cooling Fan Noisy, nit picking?
I would be the last person to claim that I have the most sensitive hearing but in my well-damped dedicated listening room, the sound of the cooling fan in my amp is noticeable (and distracting at times). I've even set the adjustable speed to the slowest setting and I can still hear it. The amp sits on an amp stand between my speakers about 10' from my listening chair and has plenty of ventilation but anyone familiar with the VT-200 knows that it can put out some serious btu's. Would it significantly affect tube life if I disconnected the cooling fan? Anyone else try replacing the fan with one that runs more quietly? Is this an "Ask Leonard" question?
