Blizzard PPC cooling
« on: June 01, 2008, 06:31:04 PM »
Well, I offered up my bppc here and people gave some really lowball offers... so I thought I'd hook it up and see if the old beasty still worked. As I expected it works perfectly, so really glad I didn't sell it for ~50 quid.

Now, the problem I have is that inside the desktop case without the top lid it gets hot enough to burn the skin off of your fingers. I ran the amidog port of darcnes with supermario for about 10 hours to fully test the ppc. It didnt crash but there was a funny burning plastic smell. The trapdoor cover I think....

What ways have you guys come up with for cooling a bppc in a desktop case? I was thinking of making a copper piece that mounts over both the ppc and 040, with a tail that comes up and out of the trapdoor (under the number pad on the keyboard) and then mounting a peltier on the tail piece... but that's a bit extreme if there is an easier way to keep the temp down.

Suggestions on the back of a postcard...

I replaced the stock 5v fan with a deeper 12v fan.. and sealed some of the edges of the ppc sink so that the air gets pushed along the sink instead of exiting out the gap near the connector. That made some difference but it's still too hot to consider putting the lid back on. :/

@Jeff

Those look interesting. I'm not sure how you would get the air in around the card itself. You have the advantage that you have an 060. The 040 I have runs very hot itself and then it's coupled with a 240mhz ppc.
