Just sharing a video of my S9 acting up, shutting down and rebooting. I can’t solo mine with it now until I sort this out or replace the whole unit. Was just getting into miners too when this one decided to break.
the one miner I was looking at has a S19 and just one board taken out and seems pretty good for a house hold miner and might buy a few more S9's

Here are some screenshots and a S9 i am having problems with
You have a high temperature due to cooling problems. Remove the fan, you will find the model there. Order these fans in your country in any well-known store. If you continue like this, you can damage the chips. Further repairs will be even more expensive.
For the future, if you are involved in mining, you should know the optimal temperatures for each chip by heart or have this information always at hand. You should have a maintenance and thermal paste replacement schedule.
Modern ASICs do not forgive such mistakes, and chip repairs are not cheap.
Okay thank you I will keep everything to what they are supposed to be and makesure things do not overheat and have thermal paste replacement bi weekly or monthly?
If you use very cheap thermal paste, then you may need to replace it once a month, but miners don't do that.
Depending on the conditions of use, good thermal paste lasts 6-12 months on modern equipment. It depends on the conditions, model and cooling system.
If you have a strong overclock, then the period can be reduced to 3 months. There are no universal tips here, you look at the chip temperature. After such overheating, I would change the thermal paste on your ASIC.
You need a good thermal paste with a thermal conductivity of 6.0 W/mK or more.
The newer one, yes, but for the S9, by using different firmware, you can disable the fan check and be able to run it without a fan. But the problem is, how can you get rid of overheating if you don't have a cooling system?
In the past, their way to bypass that issue was to have a DIY immersion cooling (Brains have this feature) aquarium as a sample with full of mineral oil. This one also helps to get rid of noisy fans.
I agree with you that it is possible to upgrade the firmware, but without knowing the basic temperatures of the chips and monitoring them, you could burn out the ASIC. ASIC S9 gives very little prof even with free electricity, and additional investments in immersion cooling make this idea unprofitable.
for me I am making slightly more then 70 cents well was when S9 was running For me in Canadian dollars I was mining 97 cents a day sometimes got lucky and mined $1.01-$1.03 a Day and had it running for 3 months and made roughly over a little 94$ BTC my family was shocked "I made money appear out of nowhere" lmao I was just happy I actually mined a decent little amount off a S9 pretty much made my money back! eyeing out perfect S19 home miners that have the middle board taken out for heat diversion linked here--- https://d-central.tech/product/antminer-loki-edition/
planning on just buying 25 of these miners for nearly 14.85K CAD (Not all at once starting with 2-3 possibly 3-5) 1 at my mothers 1 at my grams and other family members and family stores for 1050 TH/s (1.05 PH/s) in solo mining
The expected time to mine one block is the inverse of the probability:
$$\text{Expected Time (in 10-minute periods)} = \frac{1}{P(\text{block})} = \frac{1}{0.000001105} \approx 905,000 \text{ periods}$$
Converting to days ($ 905,000 \times 10 \div 60 \div 24 $):
$$\text{Expected Time} \approx \frac{905,000 \times 10}{60 \times 24} \approx 6,284 \text{ days}$$
t would take approximately 6,284 days (or about 17.2 years) to mine a block solo with 1050 TH/s. (will stack as many as these miners and more newer ones etc as i can to lower the time to hit a solo block)
$$\text{Daily Revenue} = \left( \frac{\text{Your Hash Rate}}{\text{Network Hash Rate}} \right) \times \text{Block Reward} \times \text{Blocks per Day} \times (1 - \text{Pool Fee})$$
Using:
Your hash rate: 1050 TH/s
Network hash rate: 950,000,000 TH/s
Block reward: ~3.2 BTC (including fees)
Blocks per day: 144
Braiins Pool fee: 2% (0.02)
This translates to approximately 0.000499 BTC per day (or about $45$60 per day at a Bitcoin price of $90,000$120,000, as prices fluctuate).
