Cooler Master Nepton 140XL All-In-One Water Cooling System Review

The Nepton series of AIO cooler is a “big brother” variant of their Seidon range of AIO cooler that’s made to handle processors that are hotter in operation.

Here’s a view of the packaging, simple as it is. It comes with 2x JetFlo 140 fan. I reviewed the JetFlo fans not too long ago, they’re the top-of-the-line fans from Cooler Master.

And here’s the AIO set itself, not including the fan.

The JetFlo 140 pair could be mounted on both front and back of the radiator component, or you could use just one if it’s sufficient for your setup.

Here’s what the 140XL look like on an actual setup, the casing is an NZXT Phantom 530 reviewed just yesterday. 🙂

Test Setup / Benchmarks

The computer setup used for this review.

Processor : AMD FX-9590
Motherboard : ASUS Sabertooth 990FX R2.0

Temperature was monitored using HW Monitor. Room temperature is around 25°C.

CPU load was done by converting 10bit MKV video to 8bit using x264, set to -veryslow mode.

 Idle (°C)Load (°C)
CM 140XL3254

The results were great but not without the sacrificing silence, the JetFlo fans had to spin at higher RPM. With a little fine tuning, you could actually run it at a lower RPM as long as the processor doesn’t go beyond 80c on load.

The Verdict

Retailing at RM 356 (approx 90 USD), the Nepton 140XL is certainly value for money. It managed to cool tame the FX-9590 to a sub-60 celcius range with the dual JetFlo 140 fan.

Bear in mind that the FX-9590 on stock itself is a 200w processor that’s already VERY HOT on stock setting, the 140XL did admirably. On a less demanding setup, you could even use one of the JetFlo fan as a casing intake / exhaust, or have it as a spare.
