LC3 overclock and custom cooling

so got bored overclocked my LC3 with the resistor mod. It was getting hot, so I made a custom cooling solution
keeps it cool when running benchmarks and whatever else
any thoughts? 20240505_152026.jpg20240505_152139.jpg20240505_152030.jpg20240505_152152.jpg
here is a funny little, short I made

My LCIII is also overclocked. Thus far, I have yet to add any cooling methods at all, and it seems to have been running fine, though admittedly I don't use it super often or for very long at a time. That said, I do want to add at least a heat sync. Certainly an extra fan as well can't hurt! Different individual CPUs will run hotter or cooler, from what I understand, so if yours was running particularly hot after overclocking, it may be you've done the exact right thing with the additional cooling.

Yeah I noticed with the case on it got very hot and with thr case off it was hitting 100 f 😳 so now it's nice and chilly

After over clocking my LC III, I added a heatsink to the 68030. No extra fan. It is running just fine. The temperature is about 130-140°F on the heatsink. I have put it through a battery of the Speedometer benchmarks without any issues.

MC68030 specs show max operating temperature of 70C which is close to 160F. You should be good to go with just a heatsink but make sure you have a little bit of airflow in the case to keep things in check.

According to the manual, it appears that the 68030 is designed to operate between 0° and 70° C, which means 32° and 158° F, so if it's running at ~100° F, I'd say we're golden. Of course, the IR camera just reads the external temperature of the package, but even so, that seems like a good enough place to be in my mind.

EDIT: Just saw that @danny.gonzalez.0861@gmai already posted the temps, derp!
