Noctua fans. I put them in 2 Nightowl DVR's. It saved my sanity. Or what's left of it.

Wow that easy.
Would the fan s come with the correct connection nor do I need to buy extra bits if so what bits and how do I know which fan to purchase?
Ps I am in the UK
Thank you so much for this.

measure your fans and go to the noctua page on Amazon or the web. most likely it will be at least one of these.

Hi Everyone very sorry for not getting back to you all.
I have now installed the Noctua fan and the difference is unreal it's so quiet and over 10 decibels lower according to the sound meter app.

Sound Meter - powerful in its simplicity and convenience of use.

Thanks again for all your advice.
