... and here's my old worklog:
1. Cooling system:
I have replaced the original 70mm fan with an 80 mm fan (an extreme silent one) and build some 40 mm fans at the sides:
Also I have cut some wholes in some part -> I have modified the whole air tunnel system.
Last week It was very hot and my Harddrive had 50°C so I’ve decided to turn around the big fan and the fans on the right side. Unfortunately I had to replace the big fan with another one because I had to cut away some parts of it to make it fitting in that case.
However: the HDD temperature was 9 °C lower.
2. I’ve build some status LEDs in it:
The red one shows the HDD and DVD activity, the green one the networks activity
The white wire goed to the IDE pin 39
The Brown one to the LAN controller
And the red wire is my 5V power supply taken from the DVD power connector
I’ve made a little plug with two resistors (for the LEDs) in it. Btw: you can see the old black heatsink I’ve sticked on the chipset (southbridge)
3. Light stuff
I wanna have a big load of ultra-light-LEDs (maximum power: 7-8cd) in 2 colors (red and green) which get switched by the color of the POWER-LEDs, but if I would connect all of them parallel to the POWER-LEDs my motherboard would burn trough.
So I’ve mad sth like a powersupply-HUB. I have designed my own circuit board and took 12 resistors which work like relaises. I can connect up to 5 LED devices to it.
The black wire (middle) goes to the PSU ground.
The white wire goes to to the red Power-LED, the yellow to the green one.
The LED modules get theiy power from the pin header (red and green seperated )
I had to “recycle” old computer scrap (in this case an old DVD player) to get the transistors.
