Much better made and quieter than the original fan fitted to the DVR, which had failed. Virtually silent. Some difficulty fitting the rubber mounts due to the original holes for the screws being smaller diameter, so fitted the fan with the screws provided. The screws were also larger diameter but went in with a little persuasion. DVR was recording intermittently, possibly due to the insufficient ventilation, but now recording continuously.
