Yes. I'd forgotten about that. There is a reasonably-above-ambient-noise fan that is running constantly. Another reason it was banished to the server-rack in the garage.
I got mine at Backupworks.com[1] - they seem to have a perpetual sale on for pricier items like this. They gave me a discount on a batch of tapes bought at the same time and threw in some barcodes and a cleaner tape as well.
