Well, I went ahead and picked up both types of sinks since they are so cheap. Looking at the FZ-10 motherboard, it looks like only a couple of chips reside under the drive area--the rest appear to be relatively open, so I shouldn't have to do much.
Yea, on the FZ-1 most of them are under the metal plate so the heat should be directed out of the sides. They have a good clearance for airflow, so that's no worry!
Good luck on your ez-heatsink mod, and don't forget to post a pic so I can see your FZ-10!
Did you do any testing of before and after temperatures?
I should have done a more precise testing to see what the differences were, but I basically popped in Return Fire and let it idle for about 30 minutes, then noted the feel of the air coming out of the fan side. It was warm, but not too bad.
After I popped the heatsinks on, I did the same thing, and the air was noticeably hotter than without the sinks - so it's pulling extra heat off the chips.
How did you choose which points to place them?
The center of the chip is usually where the 'guts' are located, so I tried to hit the center of each chip.
This machine used to be owned by a smoker, so an easy way to tell what components get hot is to clean them to see how dirty they are.
(This is a discovery after working on electronics for years - Hotter chips tend to bake that nicotine/tar on faster than cooler chips).
The dirtiest chips were the RAM chips, followed by the two 3DO graphics branded chips, the ARM chip, the chip on the bottom left of the picture that I couldn't find any real data on (DA623827PF J), and the sound chip.
Also, the bridge rectifier in the middle right gets really hot, so I sinked that, leaving some sink above to allow (hopefully) faster heat dissipation.
I cleaned all chips with 91% Isopropyl alcohol and cotton swabs until the swab came back visually clean.
