Sonnet recently replaced my Sonnet Encore 1.4 fanless model that had a bad L3 cache with one of their new fanned models. For those of you not in the know, in a Digital Audio, the RAM is about 3/8 of an inch below the processor heatsink... very close. This causes a problem with the Sonnet upgrade, as the fan on the heatsink is blowing down, directly onto the RAM, and the video card. As you can guess, I started getting kernel panics, and hard lockups, even while not running any programs that really peg the CPU, such as games. My solution was to flip the fan over, so it's blowing upwards, pulling the heat away from the CPU heatsink and RAM. So far, I haven't had a kernel panic, or lockup since.

I'm still considering drilling some holes into the top of the case, or installing a 60MM fan as a blowhole to get rid of the heat. Hope this helps someone else with a similar problem.

Wow, had i had this idea a few days before, I wouldn't be working like a nut on my G4 right now!
After upgrading my DA 466 to a Gigadesigns 1,47 card, it keeps freezing when ripping songs. The strange thing is, this happens at a relatively low temperature (~ 54 C) although the processor is rated to work at temperatures up to 65 C.

I will post a few pictures of my "Digital Audio project" later today

If anyone asks what I've been doing the last 3 days, I'll show him this picture and this one .

As I was having problems with my G4 freezing because of too much heat, I wanted something simple and cheap to be warned before this happens, so I can shut down CPU-hungry apps and save open documents.

I got this thingy, a 5,25" DigitalDoc5+ with 8 temperature sensors, fan controllers and warning beeper, ripped the electronics out and installed it in the 3,5" bay which wasn't easy at all.

The digicam seems to have a problem with blue light, it looks a lot better in real!

Zubir, I tried your tip and until now it seems to work, the RAM seems a bit cooler than before

Nice!

Too clarify, on the Sonnet upgrades the fan is mounted on the side on the heatsink, not on top of it, like on PC processors. When mounted in a DA, the fan on the Sonnet upgrade in blowing horizontally through the heatsink, pulling hot air from the top of the case and the heatsink directly onto the RAM, which is directly below the processor. Hence, when I flipped the fan over, the hot air is being pulled to the top of the case. I don't know how the fan is mounted on other manufacturer's heatsinks, so your mileage may vary. Sorry for not clarifiying this in the original post.
