How Can I Install a Case Fan in TV Cabinet?

post #1 of 13
Thread Starter 
Hey guys,

My friend's TV cabinet is pretty small and not very useful for lots of electronics. He just has the bottom piece btw. I helped him build an HTPC using a slim Silverstone HTPC case.

The components he has are,
HTPC
Motorola 2500 (FIOS TV box)
XBOX 360
Wii
XBOX Controller docking/charger
WII Controller docking/charger

I suggested the docks should go in a cabinet and wired in there out of sight to help save on space. Also suggested the FIOS box go on top of the HTPC with a case fan behind it to vent air. The only thing is if we get a case fan or two in the back and wire it to a 12v AC to DC transformer, it will run 24/7. I would like to either run it in sync w/ the TV or in sync w/ the HTPC. I think the best way to do this is either get a fan controller (if it will fit on this TINY case) or a smart surge protector.

Thoughts?

Get a 200 mm fan and run an extender from the HTPC motherboard (which you can use a molex to fan connector to hook up to the power supply) to where ever you want to put the fan. Also, from my limited knowledge on fans, I believe you can hook it up to a 12 V source and that should be fine as well, but why buy the extra parts when a molex to 3 or 4 pin fan connector costs very little.

Is there no opening on the shelf where the PC sits?
So the problem is the hot air venting from the HTPC is stagnating in the shelf?

Cut an opening in the shelf behind the HTPC and install a higher RPM exhaust fan on the HTPC. The system does not need much air circulation to cool properly but the higher RPM exhaust fan will push the hot air in the shelf out the back keeping everything cool.

You could also cut a small opening in the shelf instead of a large one and add a duct from the HTPC exhaust to the smaller shelf opening and vent directly.

The exahust fan on the HTPC should be all you need really.

There is a hole for wiring... did you look at the case? There is spot for a rear exhaust.

You could get a cheap crappy PSU and wire up a switch to the 24-pin.

How about this for a power supply? $12.00

and then add this programmable themal fan controller $40.00. Looks like you can add up to 4 fans. And then they would only turn on if the temp inside the cabinet got up to your limit and then shut off.

Hm... trying to save money so i think a fancy $40 fan controller is out of the question.

Ya this is the shelf?

So it doesn't look like the case has a dedicated exhaust fan port. As a simple method I'd widen or make a new hole in the Shelf to mount a 120mm PC fan, then simply run the fan connector to a molex connector or fan connector on the motherboard. Very cheap and easy to do. Only thing is you have to mod the shelf a little. If the back of the shelf is that cheap cardboard then it should be simple just measure the circle hole for the fan and the 4 holes to mount it and use scissors or a razor blade, but if it is wood you need proper cutting tools.

You will want to have the fan exhaust out the back of the shelf to direct all airflow in one direction. With the fan tied to the PC you can easily control it. A 120mm fan is the best balance between size, noise, and a moving air.

That's the route I'm leaning towards. It is wood, not cheap cardboard like I was hoping. He only has a small hole saw. Need to purchase a 4.5" if i can find it. Wait, 120mm = 4.7" :| crap.

If you can't find that specific cutter what you can do then is have a 1 inch spacer from the hole to act as a shroud to the fan, kind of like a turbine. It won't actually do anything but will allow you to mount a larger fan to a smaller hole. If that spacer is less than an inch it will be too close to the fan blades and will cause turbulence and noise, and will hinder the airflow a little bit.

This basically... The point is not for the shroud to fit the hole, but to allow the Fan to still have enough room to push air past its' frame and through the smaller hole.
