Howdy, This is in response to Sidney Ho's request that I redo my temperature test on the Comet chuck goolsbee worked on this winter to beef up its heat dissipation properties. He used lots of gap filler and heat compound, plus he added a copper plate between the Interware 320 cpu and its heatsink assembly.
Here are my results, wildly unscientific as they are, using the "G3Strip" and "Essential PowerBook Strip" csm's to find the "Internal" temperature of the machines during and after some file-copying. (Sorry, that's all I had time for.) The source for the files was a 2.5" 5GB drive mounted into one of those handy plastic external drive cases (from MCE) which connects via PC Card (natch!). Throughput was about 1MB/sec. Temperatures are Centigrade. Test machines are set flat on bedsheet on bed, a notoriously hot situation. Not to worry though... First I tested another Comet 320, "Blue Comet," with no special cooling fixes, by transferring about 500MB of various files to it. Then I did the same with the goolsbeed "Black Comet." ---------------- for "Blue Comet" G3Strip Essential Strip on for a while, idling: 48C 56C after 50% transfer: 56C 58C at completion: 56C 58C idle, 5 minutes later: 56C 58C ------------------------- for "Black Comet" w/chuck's mods... idling: 28C 37C after 50% transfer: 36C 42C at completion: 40C 45C idle, 5 minutes later: 36C 47C after 5 more minutes: 40C 48C Then, put Comet to sleep. ------------------- Somewhat later on, I transferred 2.1GB of 2,766 mp3 files to the goolsbeed "Black Comet." on waking: 36C 37C 1/3 done: 44C 49C 1/2 done: 48C 54C 3/4 done: 52C 59C at completion: 52C 60C idle, 5 minutes later: 48C 59C 1 hour later, bottom is very hot! But temps are: 52C 61C after 1 hour more, idle but now sitting on LapBottom pad: 48C 58C ------------------------ My guess is that transferring the 2.1GB's to "Blue" would have probably resulted in about 10C more heat at the transfer's completion. Of the two csm's, G3Strip's readings were usually closer to those of Gauge PRO and G3/G4 Cache Profiler than to those of Essential csm. (Sorry, Sidney...) Both csm's are shareware. I prefer G3Strip because the temperature is always displayed, while Essential strip requires a mouse move and a click. Conclusions (apart from offering negative comments on my "methodology")?
