So I'm migrating all my gear into a closet in my garage to keep it tidy and out of site, but I need to install some kind of vent and fan above the door to keep things happy and cool. I've seen some nifty all-in-one units from the USA like this:

 

https://www.acinfinity.com/component-cooling/closet-fan-systems/airframe-t7-white-av-equipment-closet-and-room-fan-system-17-exhaust/

 

Anyone seen anything like this in NZ? Or have a good suggestion on something that is easy to source and setup here in New Zealand?

 

Or can anyone post photos or ideas of what they have done to setup ventilation / exhaust fans for home theatre AV closets?

i use a 150mm mixed flow fan with a 150mm inline filter on the inlet side, the filter is a sock filter that can be put through the washing machine and it draws cool air from under the house, then at the back of the server there is a cowl type thing that the ducting it attached to and then ducted in to the roof with the fan suspended from the trusses with bungees and then it is pumped back in to the hallway of the house to create positive pressure within the house, so far there hasnt been much condensation and the servers fans idle along, the amount of air from the mixed flow fan is ridiculous,

I built my "server" in a kitchen cupboard, and that's housed in a weird outdoor cupboard which doe have under the house access.  I put 2 120mm fans as exhaust in the top of it, and 3 at the front for incoming air (on a thermostat).  Gets a bit warm in summer, but no condensation that I've noticed.

Do you really need the ventilation?

 

My gear is in an unventilated storage cupboard and I haven't had any issues with equipment failure (except for an early model ocx ssd) in the 10 years or so that my house was built. 

 

It does get pretty warm but has the advantage of keeping the towels and sheets in and stuff nice and dry - the modern equivalent of a hot water heater cupboard haha.

 

Although, if yours has AV equipment it could be an idea, amps do get really hot .

Yeah, I definitely need ventilation, but that is primarily because there is no place for heat to escape. Crack the door open seems enough. Passive vents might be enough, but I'd love create just enough negative pressure so that it draws air in from under the door where there is an air gap.

 

 

 

@davidcole - what kind of 120mm fans are you using? 12VDC case fans? If so how are you powering them and how did you mount them?

Just regular (cheap) computer ones.  I cut a slot out of the back of the cupboard and have a 12v power brick wires to some molex connectors (for the rear ones).

 

The same power brick runs a wire to a molex connector into a cheap temperature + relay with a 12v output that then powers the front 3 fans when above 20 degrees - which is pretty much all the time.

Nicely done!

 

I really like that bracket/mount for the fans. Did you make that yourself or was that sourced as a single unit? If so, where did you get it?

 

And where did you get the molex to 12v power brick?

Just a piece of acrylic that's had 120mm holes cut in it, then spray painted white.

 

The 12v usually uses a 5.5-2.5 DC barrel connector: https://en.wikipedia.org/wiki/Coaxial_power_connector

 

So i just got a 55. 2.5 Barrel socket from jaycar/aliexpress (https://www.jaycar.com.au/2-5mm-pc-mount-male-dc-power-connector/p/PS0520 ), and wired in a molex socket (https://www.jaycar.com.au/idc-pc-power-plug-4-pin/p/PS0740

I just use one of the extractor fans from bunnings (thorugh the ceiling into the roof cavity, connected it to a wemo power plug and turn that on and off based on temperature in the closet.

First time poster, long time lurker checking in :-) This is what I've done except with a temperature sensor plug from Bunnings.  Works well so far with fan coming on when warmer than 22C.  https://www.bunnings.co.nz/arlec-temperature-controlled-programmable-timer_p04420584
