120mm Fan Testing on an MCR120 Radiator Round 6

[Philwong]

Thanks for testing out the AC F12, Martin.

I also find these budget fans excellent for value and performance. What really seals the deal for me is the PST function or PWM daisy chaining. This allows me to tap the CPU and GPU fan headers to throttle my radiator fans to achieve optimum noise vs. cooling balance.

I've four F12s wired up to a single CPU fan header using only the PWM and RPM rails. Power is pulled directly from the PSU via a simple mod. Works fine for my 5870 GPU header as well.

Some folks have highlighted that the CPU/GPU temp's fluctuation may be higher than the coolant, but this approach still works relatively well for the F12 without audible noise issue from my seating position.

I was previously using YL SL and some of them tend to tick at lower RPMs even without PWM control.

The thin cables are a flimsy, but they can still hold up pretty well electrically.
