[quote user="Big_Buck"] OK. That is very common. This one: https://www.digikey.com/products/en?keywords=9WL0412P3J001 has a little less air flow, but at 150,000 hours, it is almost tripple the life. And all-aluminum frame construction 7 db quieter, PWM. Thanks very much Paul, that one still seems very noisy at 51.0 dB(A) I've used the selection process for between 30 and 40 dbA and get this: https://products.sanyodenki.com/en/sanace/search/?t14_1=&c1=on&t1_1=40.0&t1_2=40.0&t2_1=10.0&t2_2=119.0&c3=on&c3_2=on&t4_1=0.020&t4_2=12.500&t5_1=1000.0&t5_2=32500.0&c6_1=0&t6_1=0.091&t6_2=31.500&t12_1=3.20&t12_2=1112.00&c7_1=0&t7_1=8.80&t7_2=1950.00&t13_1=0.035&t13_2=7.830&c8=on&t8_1=30.0&t8_2=40.0 Anything there I could use? Easy. Good luck Paul Jr [/quote]
