Cooling system

[Hakka]

Here's some pics of some cooling fans I added to my equipment rack over the weekend. I also attached a duct to the front of my projector (covering the exhaust opening) and ran it through the back of the wardrobe into a wardobe in an adjoining room, with a fan mounted in the far end of the duct.

I used 80mm pc fans and a 12v plug pack. I'm not sure what the db rating of the fans are but the fan noise from my projector is slightly louder, so when its on you can't hear the fans.

On warm days I was having problems with my small room heating up, usualy about 1 hour into a movie it becomes uncomfortable and I have to fire up the pedestal fan but it it quite loud. I've watched 2 movies since installing the fans and had no problems.

While I was installing it I added some rigid fibreglass around the projector cavity to absorb noise, this worked very well.

Not sure I get how the rack fans are working. What are those grills in front of them?

There is a Rotel RMB 1075 on the bottom shelf and a RB 1070 on the middle shelf, the fans blow air across the tops of them. There isn't much clearance above the amps and they tend to get quite hot. Here is a front on pic of the rack (taken before I installed the fans).

Nice Job, Hakka. Can you hear them when they're on? Are they distracting?

The noise from my projector masks the fan noise, so its not an issue during movies or music.
