Hello SPCR readers! First I'd like to thank everyone on the boards and the people at SPCR. I got many a great idea from you. And now, here is my rig. It's nothing fast, it's very quiet but not silent.
case: Enermax CS10181
cpu: Athlon 1.8
hd: Seagate Barracuda 40gb, Seagate Barracuda 80gb
So you may be asking yourself why I used this case. The answer is simple, I like how it looks. When this thing arrived in the mail, I had no idea just how big this case is. It's big.
As you can see there are 2 slots that house the 80m fans. Bad air flow. I fixed this by removing the hd drive rack.
Here it is removed. Also, while I was at it I got to work on removing ever other thing that had no particular use.
I then built this simple but functional hd suspension, aluminum and rubber tubing from Home Depot. I tried riveting this thing on but it was not strong enough so I bolted.
Now with no way of mounting the fans, I built these fan duct thingys out of plexi. I used hot glue to asseble it. The "tape" at the top of the pic is 3m insulated wire tape. I wrapped it around the housing where it will contact the metal case. The white stuff on the outer edge is double sided tape. This stuff is very very strong. It is used in RC car's to mount servos. I use it here to mount the fans.
Here it is mounted on the case. As you can see, my thought process was to mount the fans as far from the front of the case as possible to reduce noise.
I blocked all the vents with that clear plastic stuff that products get packaged in. You know the stuff? The packaging that's hard to open and you can cut yourself on if you're not carefull! Anyway, I mounted it with hot glue. This will then get covered with acouti stuff. Why bother? I didin't want dust sticking to the exposed acousti stuff adhesive.
Next I built heat sinks using aluminum U channel.
Here it is mounted on the drive and the drive on the sling.
This thing is a duct that will direct fresh air from outside the case to the PSU.
Here it is mounted. The PSU is mounted upside down so its venting from the top.
I began to realize that plexi bounces sound real easy like. So I unsulated and damped it.
Mounted, never to come off again. I think..
this is the PSU fan with foam shock absorber mounted to it with hot glue.
Here it is mounted to the outside of the case (mounted with servo tape). It's outside becase I didn't like how close it was to the components on the inside. When a fan is too close to something, it creates turbulance, and that creates noise and bad airflow. I don't know.. maybe it was a silly idea.
Shrouded (mounted with servo tape)
More shrouding and dampening and servo tape. The lower shroud covers the exhaust fans. I completely cut out the punch holed grate and built housings similar to that on the front of the case.
Damped, Nuff said.
PSU "suck hole", not to be confused with "blow hole". I cut a hole and put that circular grate on.
Exhause fans mounted.
blocked front grate thing with plexi to stop noise from escaping and cut a larger hole at the bottom.
This is a wiring diagram to the switch I installed. It switches my fan controller from 5v or 12v. With 5v switched on, i can control a range between 3.7v and 5v. With 12v switched on, I can control between 8.6 and 11.6. I ended up keeping it set at 5v anyway. So what was the point? I don't know.
See that little thing sticking out next to the power and hd led? That is an external switch I built. It seemed silly to me to open the door each time I wanted to power up my machine. Anyway, it pushes through to the actual power button. Used 1 lego part, hot glue and the rest spare junk lying around.
HD's sitting happy, snug and vibrationless.
The finished rig weighs a wopping 54.4 lbs. Should have mounted wheels..
