Dear customer,

Congratulations on choosing the Noctua NF-A20 5V.

We from Noctua always strive to achieve superior quiet cooling performance

regardless of whether it’s a big 200mm fan or a small 40mm one.

That’s why the NF-A20 5V sports many of the features and advanced

aerodynamic design measures of our award-winning larger models, making it

perhaps the most thoroughly optimised 200mm fan on the market.

Each Noctua fan is double checked for flawless operation by our quality control

team before it leaves the factory and I’m confident that you will be able to sense

some of the research, attention and care we’ve put into making this product.

Enjoy your NF-A20 5V!

Yours sincerely,

Roland Mossig, Noctua CEO
