PinMonk Thank you. I ordered two of these. One for my GOTG and the other for Star Wars. Put the first one on GOTG and got the positive paper towel air flow test. Last night after company left, I had all the games on without the TV. Totally quiet downstairs. The only game I could here was Star Wars. Stock fan ramped up every so often. Very, very obvious. So I went and listened for our other spike games. I could hear KISS, and GB but not bad. These had the older style stock fans that direct vented out the front, not the top, so I did not use your replacement fans.
But GOTG! I could only hear it if I really listened. Wonderful improvement. I will be changing out the SW fan this afternoon or tomorrow! Great job and thanks again.
