Is it silly to spend $17 on an upgraded heatsink for my #Bitaxe when I’m only mining 65 sats per day, best case?

If I increase that to 75 sats per day with the new heatsink and overclocking, what is my time to ROI if the sats increase in value at an average annualized return of 43%, while the $17 decrease in value at -5% annualized? Assume zero energy cost with solar, no halving, constant mining rate, 100% uptime and no other variables.

Does #nostr have spreadsheets yet? 🤔
