Adding fan on 6100 with DOS card.

[crazyben]

I am thinking of adding fan in 6100 with DOS card installed. As you know both CPU are exactly on top of each other and when they are running it gets quite hot. So i am thinking of adding a 5V or 12V fan to cool things down. Has anyone done this? I will be installing Zuluscsi on there so i have free molex cable to draw power from. Something like this

I usually default to a 12V quiet fan. 5V runs a lot of important logic so I try to avoid using it for extra stuff if I can.

I recommend sourcing a Noctua, so much quieter than cheaper fans. https://noctua.at/en/products/fan

Drawing power from a molex should be just fine, and many Noctua's come with cables.

Thank you i will check it out. Only reason i was looking at cheap was for compact size. Since there is not much room in 6100 i need to find one that fits.

Good deal, they make tiny ones, I have 40mm x 10mm thick one in my LCII with a little 3d printed adapter. Whisper quiet.

I have read somewhere about a Noctua one perfectly fitted to go inside the strange 601 heater.
I think I've bought it but did not take time to install it.

Hi there, I want to optimize my 6100 machines these are the targets: 1. Replacing the caps on the board 2. Adding heatsinks on the big chips 3. Checking the fan on the power supply 4. Adding an additional fan to the case 5. Adding a bigger L2 Cache Hopefully someone can give ma some tips on...
