Thanks for the information @malford , unlukily for my job I can’t have my iPhone with me and only have mail access so the email notification is very important for me.
Hi Phil,
I sourced my fans from amazon.it. There's also the 2cm thick version Noctua NF-A4X20 but since i just have 4 camera using the POE from NVR i went for the lower noise and lower airflow version of 1cm thickness and didn't have any problem in the last 3 years.
For sure the warranty will...
Hi, I had a DS-7608NI-E2-8P and I now have DS-7608NI-I2-16P And I changed the fan to both of thme with Noctua NF-A4X10 and I can now live with the NVR without any noise problem. It's very easy to do the swap.
