A full case fan upgrade with three Einarex EX12A units costs about R747 in total. That buys 82.9 CFM per fan across intake and exhaust, enough for a complete airflow overhaul on most mid-tower builds.
Planning a fan upgrade usually starts with a vague idea of "a few new fans" rather than an actual number, which makes it easy to either overspend or buy too few to make a real difference. Working out the case fan upgrade cost properly just means multiplying one clear unit price by however many positions your case has open, and the Einarex EX12A makes that maths simple at R249 each.
Three Einarex EX12A fans come to roughly R747 in total, giving you 82.9 CFM of airflow per fan across intake and exhaust. A smaller two-fan upgrade would cost about R498, while a single replacement fan is just R249.
At R249 a unit, the maths behind a full upgrade scales in a straight line: one fan for R249, two for R498, three for R747. Each EX12A brings the same 82.9 CFM ceiling and 40.7 dBA maximum noise regardless of how many you buy, so there is no per-unit discount to factor in, only the total based on how many mounts your case has free.
Many mid-tower cases have room for at least one front intake, one rear exhaust, and one additional top or side mount, which is why a three-fan upgrade at roughly R747 covers a genuinely complete airflow overhaul rather than a partial fix.
Beyond the raw CFM figures, every fan in the upgrade includes PWM speed control, so the whole set can ramp up together under load and quiet down together at idle. Drawing only 3W each, three fans running simultaneously still add up to a tiny fraction of any power supply's output. Case fans bought as a matched set like this behave more predictably than mixing brands with different noise and speed characters.
If your case only has two open mounts, there is little reason to force a third fan in; check the Einarex EX12A listing against your case's manual first. Builders working with one of the Einarex case models can confirm exactly how many 120mm mounts are available before committing to a full three-fan spend.
Yes, that figure covers a complete intake and exhaust overhaul using matched fans with consistent specs across the whole case.
No, the Einarex EX12A is priced individually at R249 regardless of how many you purchase at once.
Yes, replacing one weak or noisy fan with an EX12A for R249 can noticeably improve airflow in that specific position alone.
Not strictly, but matching models keeps PWM behaviour and noise levels consistent across every position in the case.
Barely; at 3W each, three fans together draw about 9W, a negligible amount for any modern power supply.
