Currently they offer a Noctua DH-14 with a 30$ fan control 5.25" bay for 85$. Fan control comes with it for free, I contacted new egg because I couldn't apply a $10 new customer code and they said free item cant be removed from the product etc and code wouldn't work because I got free item. And they said buy the item and then we will credit your account $10.00 when you get a customer invoice.
To me, there are coolers that do just as well for less. The Spire eclipse II is rated higher and can be found for $55 all day long. I can find decent fan controllers for $20.
Considering the retail price of the Noctua D14, I suppose its a decent deal. I'm not buying one.
