Cooling Efficiency Tests

The results of our comparative test session are given on the diagram and in the table below:

In fact there is nothing to really analyze here. The new Nexus VCT-9000 loses to the 40% cheaper cooler in both modes: in quiet mode as well as in PWM mode. The latter is 7°C more effective in quiet mode at 1050 RPM and its advantage increases to 11°C at maximum fan speed. Moreover, you can install a second fan for air exhaust onto Cooler Master Hyper 212 Plus and this way increase its cooling efficiency a bit more. You won’t be able to do it using any standard methods on Nexus VCT-9000.

In conclusion we would like to offer you a monitoring graph for the processor cooled with Nexus VCT-9000 in the PWM fan mode:

We didn’t measure the noise from the Nexus VCT-9000 fan, but from my subjective observations I have to admit that the new cooler has a very high-quality fan that remains pretty quiet up to 1100 RPM. If you keep it rotating at 800 RPM or less, then you will hardly be able to hear it at all, and at maximum 1600 RPM you hear only the noise from the airflow generated by the fan blades. No parasitic noises of any kind, like crackling, hissing or the like.

Conclusion

We very rarely come across cooling solutions that we would strongly not recommend for purchase. But the new Nexus VCT-9000 cooler is exactly the product you really don’t want to mess with. It certainly has advantages, like universal design, simple installation and high-quality quiet fan with LED lighting. However, everything else is definitely on the lows list. We should definitely mention very raw heatsink design where straight plates are combined with an angled heatsink positioning; faulty heatpipe layout inside the heatsink; dummy heatsink above the base that didn’t get any thermal compound; horribly executed base with heatpipe direct touch technology that has a very small contact area with the processor heat-spreader and large gaps in the middle of it; simple but very unreliable push-pin retention for LGA775/1156/1366 platforms that can’t guarantee high-pressure hold and won’t last long enough; fun shaped casing that limits the cooler’s compatibility with mainboards that have heatsinks over their voltage regulator components around the processor socket - all this results into very poor cooling efficiency of the new Nexus product. At last, I should point out high recommended retail price of $50, which makes Nexus VCT-9000 market success even less feasible.

Summing everything up, we can’t leave the choice to you this time and strongly urge you to check out other cooler models. And as for Nexus VCT-9000, we hope company engineers will fix their baby and launch its new revision free from all these numerous issues in the near future.
