A4000: New fans and some minor audio mods

One more Saturday to work on my lovely A4000. Sorry for not updating sooner but last weekend I was hackintoshing my Dell Mini 9" (dual booting Snow Leopard with Windows 7) but that was not Amigish to share so... here we are once again :)

 Well first of all I thought of getting 2x new silent 80mm fans for my A4000. One will replace my PSU fan and the other will be mounted where the original Hard Drive bracket existed. After some searching around local stores I came up with a Noctua 80mm 17db - 53CFM. This fan has also 2xAdapters with resistors to lower the silence up to 10db or even 7db (ofc lowering the CFM as well). Since I tested them a bit... I thought that 17db was just fine for my taste.

 PSU replacement was easy enough... and you can barely see the difference with the previous one. Sound difference is a LOT though! Awesome \o/

Next step was to mount the second 80mm fan where I wanted. As a holding surface I thought of using one spare metal bracket that we use for the backplates of our ISA/PCI etc slots.

I straightened  it a bit using pliers and with a little hammer I gave the final look.

After that, I dremeled one side to match a bit with the other and sanded the whole bracket. It looks better right?

After the sanding... it was time for 2x coats of a gray spray paint which I used in the past for some components. Result was really neat.

Now I had to put some dual sticking foamy tape to the upper side of the fan...

...and then attach the painted metal bracket to the sticky tape! Last step before putting it in the Amiga was to put 2x tie wraps to hold the fan even better and more steady.

Here you can see it mounted in it's permanent place. It's very steady quiet and it's airflow it's just epic! Some mini heatsinks on the CyberVisionPPC and RAM SIMMS on the CyberstormPPC will be must better now :)

Since last time I didn't like the way that  I mounted the RCA cables to the internal spot of Delfina, I thought of doing something better and more good looking :)

That's why I decided the following:
  • Changing the Mic input connector (Pink) to the Internal connector on the Delfina (after all Aux2 can be used for Line or Mic so I had one spare connector).
  • Making tiny cute Mini Jack to RCA cable to be able to connect it from the Amiga RCA output to Delfina's Internal input (now Pink femal Jack)

You can see it clearly now :) Doesn't it look better? And I can anytime remove the cable and get the RCA from the Amiga (don't know why I'd do such a thing... but anywayz).

I had to include one last photo from the internal of the A4000 with the Delfina and custom cabling showing also the new fan mounting! Small update but definitely an important one.

Cheers for lookin'
