Hello Everyone,
The normal temperature for whatsminer m3 is under 84 degree.
During Winter time, FANS rpm should be around 4,000

How about CFM value for each fan ?

How about CFM value for each fan ? they must be close to 200 cfm

How about CFM value for each fan ? they must be close to 200 cfm I agree, if it is anything close to like the 6000rpm Delta fan model "QFR1212GHE", when it comes to the technical specifications. I tried to search for a data sheet for the KZ12038B012X fan, which the WhatsMiner has both in front and rear, but I was unable to find anything. Delta QFR1212GHE has a max airflow value of 210.4 CFM. https://www.digikey.com/product-detail/en/delta-electronics/QFR1212GHE-SP01/603-1165-ND/1850534

So in theory we can get a quieter 200cfm fan?

No, you can't quiet down this miner by changing a fan. Sorry. It produces a lot of heat and needs a high level of cooling.

So you only left the sides open? And you used insulation foam right?

If you mean something like in this video, it could work out. https://www.youtube.com/watch?v=QfMrOjezl7k

I realised nobody appears to have any concerns about the temperature. Is 84 degree celsius a very normal working temperature for the chips? What will be their projected lifespan? Please correct me as I am currently still running on S7s. Bitmain's S7 28nm chips are already failing after long usage at ~60. Although the straight forward profit calculation shows a fast turnaround for ROI. But in the long run, will the repair fees start to close up the gap and S9 will still remain as the more profitable miner.

I've run some S7s with low fan speeds with temps at ~84-85c for extended periods of time as well and they worked for a good year before I sold them. Repair fees could get pretty costly as they might ask for shipment back to China on your own dime just like Bitmain. Replacing the fans with a higher-CFM fan could also work. Just a disadvantage of a high-powered unit, gets more and more difficult to cool em.
