nobody is going to do your work for you. We will help out with specific question, but we won't write code for you.
I suggest you do one of the following
a) tell your boss you need help
b) study more
c) hire a consultant to do the job
d) post the same question on stackexchange and have the notoriety of a post with a -100. ;-)

Without any useful information other than symptoms, nobody is going to be able to suggest anything helpful.
Things like who makes the fan, documentation, wiring diagrams, photos, etc...
At least something more than two sentences (that contain very little information).
Like there is no description of how you injected dc into the fan.

-60dB is 0.1%. -90dB is 0.003%. Few people can hear 0.1% distortion in music but a sinewave sounds a little like a buzzer. nobody can hear 0.01% or less.
At fairly low frequencies an OPA134 audio opamp has 0.00008% distortion. A TL071 audio opamp has 0.03% distortion. A 741 or LM358 ordinary old opamp has about about 3% distortion.

Start with + input, the easy one.
VIN+ = 2.5V*(100k/(25.9k+100k)) = 2.0V.
Now ignore R2 since nobody's telling you input bias
current. Though depending on op amp this could
matter slightly. VIN- must equal VIN+. So now
I(V1) must equal (2.0-1.3)/23.7K or 29.5uA.
This must also be the current through R5, to 2.0V
(on VIN-). So VO=2.0+29.

For analog blocks low voltage is "what you do because
you must", not "what you want to do for analog quality".
Ability to integrate trumps ultimate performance. Of

Not only finite (and unbalanced) switching times in
the logic, but comparator rising / falling delay
asymmetry can cause race conditions which turn
into output glitching. In the larger picture the
flash ADC data would be registered (nobody likes
to work with unstable data) and the trick is to
ensure that the strobe avoids the hazard regions.

Most 18650 Li-ion cells do not have protection circuits built-in but some do. The protection circuit is usually in the laptop battery circuit, not in each cell.

nobody makes a "silicone" transistor because silicone is a synthetic rubber. A transistor is made of silicon, not silicone.
The germanium transistor is missing a resistor from its base to its emitter to turn it off enough that its collector to base leakage current is not amplified by it.

nobody makes one like this because it wastes a lot of battery power making heat. You can make a simple 50Hz or 60Hz sinewave and feed it to an audio power amplifier that drives a voltage stepup transformer.
