Noiseblocker fan advice

[Drumroll]

Planning on getting some fans for one of my systems.
Really tempted to try the Noiseblocker fans, just unsure how they would perform as a case fan, not as radiator or heatsink fans. Also wondering if the best option would be the eloop PWM or the BlackSilent Pro PLPS. Case is the Corsair 5000d airflow. At Overclockers they’re at some reasonable price, cheaper than the Noctua Chromax and similar to the Noctua Redux which I don’t like the colour.

They are a good fan and I used them for years as radiator and case fans before swapping to the Phanteks T30.

Good to know.
The Phanteks seems to be the go to fan now, but can’t justify, at least now, their price.
I know I would be paying for stellar performance, but for my needs, I reckon the £15 ish budget should be enough. Maybe down the line…
