I had asked about this system before, but now I realized some new possible issue with attempting to replace the fans in my system.
They are a Dell Precision T3610 and a T5810 system and they have proprietary fans, there are three fans in the front of the case all mounted in a metal cage like this:

I am planning to replace them with standard ones (adapters exist) as well as use splitters so that I will have PMW control over all the fans instead of just connecting the new fans to SATA power and having them running full blast 24/7.
I looked at the existing fans and saw that they were listed at a ridiculous 0.95A. I figured either they were just old or poor quality and since all the fans I was going to add together would not add up to that much I would be fine. But then I looked closer and saw that it also is listed as having an insane 93CFM.
Here is a picture of one of them: View: https://i.imgur.com/Pf4fkFf.jpg
Model numbers:
PVA092J12M-P
V67MK-A00
The second model number seems to bring up more results. However, I can't find any specs on them. One site claimed that they ran at an also ridiculous 6100RPM, but it's stats weren't very reliable (it claimed they are 90mm when they are 92mm. Another also claims they are 32mm deep instead of the standard 25mm, which appears to be true according to my measurements)
Now I am starting to worry that if I replace these fans, my cooling performance will actually go down, not up. The whole point I was doing this was because the system (especially around the CPU and PCIe slots area) runs pretty hot and I wanted to add additional fans as well as use the PMW signal from the existing ones to control them, but since the slots are proprietary I would need to convert them to standard fans first.... but if these are some special heavy duty fans that no standard fans can compete with then it will end up giving me WORSE cooling performance.
The system lists the three fans as "RAM Left Fan" "RAM Right Fan" and "PCIe Fan", it becomes obvious why when looking into the system: View: https://i.imgur.com/84fexnn.jpg
There is a shroud that covers both sides of the RAM that the first two fans are directly in front of. There are cut-outs on the inner side of the shrouds which I assume is so the CPU can get some of the airflow being funneled into the RAM slots too.
The third one just has some vents that look designed to make the air kinda sorta blow in the general direction o the PCIe slots area, no idea how effective that one would be.
Anyone have any information these? Are they really 6100RPM or have a CFM of 93? No other 92mm replacement fan I can find comes even CLOSE to that kind of output in either RPM or CFM. I know that RFM does not matter as much if the fan's design is more efficient so it can push more air at a lower RPM, but the best I have been able to find is 30-50CFM, which is considerably lower than the 93CFM listed on the fan itself.
