To me, future proofing sounds like buying a fan with a long life span.
For that reason, like others here have suggested, I recommend that you buy Gentle Typhoons for "future proofing".

What Bill is saying is true, but much of it is not as critical as he is making it sound. Take a chill pill Bill.
There are many fans that are just plain good fans to use for almost any application. Fans like 1850rpm or 2150rpm PWM Gentle Typhoon for example. They idle down to low speeds, are quiet, have good P-Q curve and static pressure so move a good amount of air even with high FPI radiators or high restriction filters and grills.
I suspect that the Vardar fans will not last as long as the Gentle Typhoons. There may be QC issues too.
Official stats as per EK:https://www.ekwb.com/shop/ek-vardar-f4-120er-2200rpm
- Bearing durability: 50.000 hrs @ 40°C (MTBF)
By contrast, the Nidec Gentle Typhoon lasts as long as 100,000 hours at 35C, L10. Note that L10 is far more stringent than MBTF. Actually, the L10 of the Gentle Typhoon is 60,000 hours at 60C.

The closest equal to the 2200 rpm ER Vardar would be the 2150 rpm Gentle Typhoon PWM version.
