If I had a L3+, I would go for Overclocking at time like this since
Market's almost Bullish; so just HODL your litecoins (
preferably in Exchange for a quick sell) and cash-out fiat afterwards.
Temperature and extra Power Consumption are problems though, depending on your area.
Don't know if you already know this but: it's not overclocking that's actually degrading the processors, capacitors and the boards, it's the heat and over/under voltage; whether it's under-clocking or over-clocking, it will degrade much faster if you messed up the setting.
