I recently bought two of the aforementioned case fans
and replaced some Scythes in my P182 for testing.
: surprisingly nice fans, especially at 8 euros a pop. The build quality is less than Scythe's (S-FLEX, Slip Stream). The PWM splitting function that is their trump card is okay but not great: it works but has limited reach. The fans wind down to very quiet levels at idle (30%, 20% is so inaudible it gets unnerving
) and are unintrusive for me at load (70% typical). Full blast sounded rough, not acceptable.
1. CFM/dB seems good enough. Negligible performance and sound penalties for horizontal positioning.
2. Fans transition in RPM leaps under Asus mobo control (AI Suite, 30% @40'C CPU, 100% @60'C) but do not startle. No zig-zagging.
3. Unintrusive at idle (can hear rough characteristics up to 10 cm though), audible 'woosh' at load but remains unintrusive.
4. Flimsy frames, awfully thin wires.
5. PWM signal split happens at the connector, so all wires lead to the same damn place - gets crowded fast and limits reach considerably, you cannot wire an entire ATX case from the CPU_Fan connector
6. RPM wire separated into its own connector and apparently needs its own connector (I took it from the instructions that I shouldn't put it through a chain, only a single connector's extension, see Observation 7).
7. Instructions poor but have big pictures, can roughly figure out what's supposed to happen.
: people who want quiet and automated case ventilation on a budget, have (adjustable) PWM control and only need a couple fans.
: die-hard enthusiasts, anyone with fans in more than one place, mobos with no extra connectors post-install (for RPM).
: They're a keeper. You just can't beat automation.
