Overheating BPPC component

[x56h34]

Here's how I attached a fan on top of the PPC heatsink. It's a VGA 12V fan which I secured with adhesive thermal paste. The PPC heatsink is used as originally planned. I removed the old non-adhesive paste from the top of the 603e chip and I put a fresh new coating (since the old one looked kind of dried out). The old PPC fan underneath the card has been disconnected, as it attracts dust around the 603e. It's not necessary anymore, with the 12V fan in place. There's more than enough cooling. When I touch the PPC heatsink during play of a PPC game for example, it only feels slightly warm. It doesn't burn my finger as before. :-)

@delshay:

The newly added bigger, more powerful, and overall much better heatsink adds plenty of cooling. The old fan would only attract unnecessary dust in the area of the 603e chip, if I were to plug it back in.

@delshay:

So those chips are not touching the heatsink, but they only are dependant on the small Phase 5 fan blowing on them? Is that what you mean?

@Framiga:

I would just like to make something clear about my solution. The original small phase 5 fan attracts dust if it's turned on and working. I didn't meant that it attracts dust just by sitting there regardless of it being turned on or off. :-)

If that fan is turned on and spinning, the heatsink on the other side provides a perfect cover for any dust that's sucked in by the fan to stay there, in the area of the 603e chip. That's why I suggested unplugging that fan from receiving power. The dust build-up around the 603e can eventually kill it.

You will not notice any dust problems right away, but it will slowly build up in 6 months or so.

This is a very tricky task...to properly cool the entire BPPC weak spots. :-)
