"I had an old Zotac mini PC, it was fanless and really only had a slab of aluminum for a heatsink. I cut out the top of the plastic case so that I could fit first an AM4 heatsink, then on top of that a stock Intel heatsink and last but not least a cooler master hyper 212 tower cooler. It actually worked well enough to keep the CPU from constantly throttling."
