Low hashrate over my LHR periodically, which is not getting corrected automatically

Im mining with MSI RTX 3060ti ventus 2x.

I’m new to mining

initially there was hashrate issue. it was mining at 29 Mhs insted of 60 Mhs.
then NicehashQuickminer. solved this issue…
wheres. I got 50Mhs in return…

Now there is a reduction in hashrate periodically. which is not getting corrected automatically by the Nicehash Miner…

Once LHR becomes active and reduces hashrate. It is not retriving even for days.

20th of june 2022 10am. my minere started to mine at 30Mhs on my 3060ti card

its 24th and there is no improvement… its mining between 25 to 30Mhs

Previously I used to restart the system…

But I need the hashrate to get automatically corrected…
Waht if I’m out of town for four days…

so plesase help me out

Have you done any overclocking and/or undervolting? Have you been watching your thermals?

On the line of thermals check your fans and check heat sinks for dust clogging the fins I have had that happen to a CPU cooler once long ago.

fan speed and thermals are below the average level of the fiven limits by the manufacturer…

At the time of low hashing/…

but why im getting Lhr switching… even when Im running LHR optimized Nicehash…
