Cheap fan silencer

Just made this for my room, cost about $20 and cut my fan noise by 3/4, all you need is a bucket with a lid 2 150mm duct connectors some mesh to roll the center pipe and some polyester stuffing

Very cool!!!

What's the temperature inside this contraption with the fan running?

Inside my room or inside the silencer?

The silencer.

I use the same method but switched to rockwool, after a few months the polyester had gotten mouldy.
Cheap and very effective!

I have mine hooked up between my carbon filter and my fan in my room so it gets about 18°c to 25°c

That's mine hooked up

Mine is on exhaust just to stop the whooshing noise, which was loud especially at nighttime, I don't have the space to put it between the fan and filter.
I can stand next to my exhaust and it's near enough silent.

Yeah mine works a treat I made a bigger one for the exhaust end, with both of them and the fan box I made it's pretty much silent
