Okay this below is 'normal' with a 3050 watt cap
Yes, you want to keep the power mode on normal when setting a power limit on the miner, it's almost impossible to bring the miner to an exact figure, so your 3050w limit will usually be slightly less, a few watts here and there, also, the power consumption on the tool isn't 100% accurate, so make sure you use a wattmeter to get the exact correct number.
I would also look for a different tank, 6kw is too much for Antminer and a bit on the low side for 2*Whatsminer, but at the end of the day, the lower you go on these Whatsminer the more efficiency you gain overall.
Also if the project kicks in and you want to sell the package as a 200th miner you would want to get the M50, they range between 25w/th to 28w/th, the lower the more expensive of course.
The M50s 110th 28W would be a good pick, it should do 110th at 3080w default, so if you want it to stay at 2900w (to not go above 5800w for the tank) it will do 103th or a total of 206th for the tank.
Meanwhile, keep in mind that you will remove fans in the tank, the reading on the wattmeter will take the fan readings too, the fans in the pics you posted are running close to full, they consume about 85w each at full speed (7k rpm), so the reading on Whatsminer tool will be a lot more accurate when the miners run in the tank.
I don't mind if I am short of 200th and end up selling a 180th machine burning 5800 watts.
The key with the unit I am using is it is a 2 whatminers piece. The cooler has the ability to heat in the winter and warm a pool in the summer. My partner "buysolar" has been doing solar setups in New Jersey for 20 years. We may work the angle a few ways.
Also we may do a single whatsminer m50s+ overclocked if they supply a proper psu to do that.

what matters down the road is how good the cooler is. It could be a bust. which is why we got the m30s+ to test it just in case we don't like it.
what I have found interesting is:
'normal' and 3100 watts = good
'normal' and 3050 watts = good
'normal' and 3025 watts = testing now>>>> edit :
now doing:
unit 1 >> 92.509 th 32.56 watts a th and 3011 total watts
unit 2 >> 92.490 th 32.62 watts a th and 3017 total watts'normal' and 2950 watts = fail
'normal' and 2900 watts = fail
this is not to complain but may mean the cooler will struggle with 2 m30+ on normal and 6100 watts.
Typical designed just a bit wrong and yet they push 2 whatsminers as a fit with the cooler.
Likely need a quart more liquid and a little bit bigger radiator to be perfect
now on low setting I did 88 and 2875 watts which is 32.67 and 2 of them would be about 5750 watts.
so low setting may be needed for the coolers.
I will post back to see if I can play with settings a bit more.
Maybe with a day of burn in I can set lower than 3025 watts on normal.
