Since I got L3+ I have had itch to overclock it even if it voids warranty. So I have done a bit of online research and after a couple of days of stable running I decided to go for it. I have overclocked pretty much any CPU/GPU I have owned on desktops in the past(not servers or laptops) and so far only fried 1, it was back in 2004-2005 with Athlon XP 3200 when I tried to push too much voltage and it did not have any protection. Since then I have not killed anything keeping voltage sensible. As the L3+ only offers frequency change and nothing to do with voltage I thought it is fairly safe to do it as long as I keep temperatures low which should be achievable considering that S9 uses the same design consuming 1200W and L3+ is only 800W. Theoretically it voids the warranty but would Bitmain even know I overclocked( unless they read this post) and I expect it would be single chips or hashing boards failing first and not the whole thing so repair cost should be acceptable. Another factor is that there are other batches coming soon which will increase network hashrate and decrease payout so it makes sense to get as much as possible while I can.

To cut a long story short I have gone from 384MHz to 462MHz which increased hashrate from 500 to 600 and increased payout from £500/month to £600 while electricity costs went from £65/month to £80 so net increase in payout of £85. And temperature increase from 59C to 62C.
