Due to our main supplier not having the 24V 40×10 mm fan in stock and other suppliers increased their prices we have decided to temporarily swap out the 40×10 mm fan to an identical with a slightly lower air flow. The differences are:

Original: 6 CFM, 20 dB(A)

New: 5 CFM, 14 dB(A)

As soon as the original fan is back in stock (expected in August at earliest) it will be available for purchase.
