Do you have by any chance the config file of cgminer for your L3+ ?!

it is in /etc/config/cgminer
i'm looking for the "option freq" part

Thx..

Any one know wath is the airflow in m3/h or CFM moved by originals ventilators? because 80dB is really louder.
But another ventilator with low r.pm but biger, something like 150mm or 170 to slow down the rpm and dB.

A majority of the noise is a by product of air flowing over the heat sinks creating turbulence. If they need say for example 250cfm flowing through the l3 to keep cool then it doesnt matter if its from a 24" fan or the stock fan. The same amount of air is going to flow through causing the same amount of noise. Now you might reduce it a little bit but not much.

Just my 2cents

I dont think the noise come from the airflow between heatsinks. Because is not whisper sound is like you say turbulance and this are made by the blade of the fan.

I'm super conservative if it comes to OC. I would rather mine longer with the same machine than having to deal with repairs and other stuff for a short-term gain.

However, I just OC one of mine to test it. The info in here is really nice and helped me a lot. This way i don't need to click it up 10 times to see what output is going to be Cheesy

I have 5 of these and tested 2 with watt meter.. 860 watts each not overclocked! So I would say 2 out of 5 that is the typical wattage being used. 1765 Watts from the 2.

Hi guys, I have few questions.

What represents the column HW in the Miner Status?
I see that after overclocking value in HW column changed for hash board (Chain#) 1 and 4.

What is your experience after month of L3+ works overclocked?
Is overclocking safe if the chip temps are OK?

i have 3 miners and one overloked...if you make good air conditioning system everything will be fine) Cool

Thanks, this info was helpful, I have one question I have a PSU 1200W connected to my L3+ can this PSU handle the overclocking? I have a 110V power Outlet.

I think you can if it's a good PSU, some of them can't really give the same continuous power as wrote on package.
Anyways, you can try to go up to 400M, it will draw a bit more but not more than 1000W, but be sure they are well cooled !

My antminers L3+ are running O/C at 462M with a power draw of 890-930W.
I use 1600W PSU from Aliexpress.

this looks like a very dangerous job, my friend! you can damage antminer l3+ because it looks like the temperature is above what it should be but it has been a beautiful post Roll Eyes

My L3+ chains run at 60c,61c,60c,61c at stock speeds with fan on auto. 51c if manually setting fan to 100%.

i think this miner will be worth very little after warranty expires. it makes good deal to gamble and get 20% more coins. crypto value is very risky by ifself so overclocking miner imo is no bigger risk. i doubt all asics will die at once anyway.

Per Bitmain support : Over clocking of antminer will void your warranty. Should at least wait until your warranty expires after 180 days otherwise its a big gamble.

why do you think 60C is too high for Asic core? i think it is very ok temps. i would be concerned if temps go over 75C. the over all airflow is very high so you just need stable ambient temps to cool this miner. "tube" design is good idea for optimal airflow. what i do is lift the back of miner so hot air escapes better, but with such airflow this is overkill anyway Grin

i think next what is worth trying is putting rig in special liquid so all components are cooled better.
