My latest creation Baby Master Blaster

[medicinehuman]

In the beginning.

Here's the heat sink after sanding. ( went over it again after this picture.). Now an aluminum piece 1/8" thick over fins and then fasten down fan. I then took it apart and drilled holes for power in heat sink cover and center of heat sink Next I started the frame work. I put 3/4" square tube down on the heat sink flanges and drilled holes for bolts and mounted LED driver on one end ran some wires and mounted fan power adapter on other end

My computer is messing up, can't post pictures right now.

Here's how I reinforced hangers, they are made of 3/4 heavy duty aluminum angle metal. I ran them flush with the bottom of the square tube, I put one on each corner and put a bolt through it and then cut a small piece of aluminum angle and fit it to inside of angle and sitting on square tube and fastened with screws. It is quite sturdy now. It is ready to put in to the chassis now. It's a snug fit but that's OK. just need to drill and cut holes for power, lighted rocker on/off and the dimmer control.

Nice job, that's how I like it done now. In a box with everything nice and secure. All the connections carefully done..sweet.

Thank you Pos, I didn't mention that the 200mm fan is doing a great job and is super quiet. I put temporary top on til later this week. There is a couple of vents on top for now.

I am proof that you can teach an old dog new tricks. I now have my CXA's working more efficient. I have been growing dirt for only 3 years (except some younger day's outdoor grows 30 some years ago) and have finally mixed my own soil mix and switched to cloth bags. Now I should see some better results because the girls are going to town. I can't believe how fast (big) they are growing now, maybe I will get my gram a watt finally. Pictures don't do justice but anyway here they are. A Lemon Kush and a kinda stretched out World of Seeds ? These are under 2 CXAs each @ 1400mA, The first is 3 weeks and the second is 1&1/2 weeks old. Couldn't have done it without this community, Gracias.

I do have a lot of fan's going, it is a good insulated room in my pole barn so no one hears anything.

I got a question about fans, to blow or suck through a heatsink? I know a lot of computers blow and some suck. I have mine all blowing on the heat sink and they seem to be running pretty cool to me. I looked around on the internet and blowing was the most as answers went. Does anyone know better?

Blowing the where its at. I have experimented with reversing the fans and it is no bueno time.

...all clear for me now...
