Enermax ETS-N30-HE Review
If you are one of those users who need simple, small and still good performing air-cooler, then Enermax has something for you. It’s pointing mostly the mid-range systems and users on a budget and is available in two versions. HE for high efficiency(slightly more airflow) and TAA for T.B. Apollish Advance (circular blue LED PWM fan with nine LED diodes and “Twister Bearing” technology)
Enermax implemented couple small innovations in order to achieve better thermal transmission between CPU and the CPU cooler. One of them is for example the HDT (heat-pipe direct touch) structure where all 3x ø6mm copper heat pipes are directly contacted with CPU surface. The contact area is polished and have plane contact surface. Supplied thermal paste is from Dow Corning TC-5121.
Unique air path is creating high Vacuum Effect Flow (VEF) through air channels between fins and according to that, the CPU cooler sides are not fully closed, so that cool air can be sucked into the heat sink.
The fins has four holes to enhance heat transfer. This patented system is called Stack Effect Flow (SEF) –
Warm air is rising up because of its lower density and leaves a low pressure behind that in turn pulls cool air. Four openings in the middle of the heat sink make use of this effect. They interrupt the air stream so that the warm air gains space to escape. Thus, the heat dissipation can be accelerated.
The ETS-N30 supports Intel and AMD sockets, with universal metal bracket mounting system including Intel-775/1150/1155/1156/1366 and AMD- AM2/AM2+/AM3/AM3+/FM1/FM2/FM2+ sockets.
We found the 92mm fan actually quite silent even on higher rpm. With 12V it’s still running with approx. 28 dB(A) of noise.
You should not run into any problems even with higher RAM modules.

To ensure that the results from one review to another are comparable, the Testing Methodology will be the same throughout all reviews, otherwise we will make a note if somethings changed and keep it separately from other results.
All testing was done on test Bench-table with a room ambient temperature of 22- 23°C and if temperature changes we will add delta T °C to the results.
Before testing we run 10 minutes of Prime95 followed by 30 minutes of idling. This warm up period was done at stock CPU core frequency.
For noise testing we ensure the PSU fan is isolated or using fanless PSU and we don’t use any graphics card. We mostly do fan noise test over night so we have our room as silent as possible.
We take values at IDLE and full load – where all fans run at their maximum speed.
Testing system :
For testing we used OCCT software and between each test we left the PC at least 15 minutes to rest so that the temperature went back to the IDLE state. Followed by overclocking with help of Easy Tune Software. Each test lasted for 15 minutes. If the temperature of any CPU core exceeded 85°C the test was automatically turned off and the value of the results we have marked as “failed”. The resulting temperature in the tables are the average temperature of all cores. The results of the tests are influenced by many factors such as: the amount of thermal paste, pressure between the processor and CPU block, humidity, thermal conductivity of thermal paste, etc.. Therefore this results should be considered as indicative only.
For this test we use it’s own thermal paste provided by manufacturer.
Installation was very easy. If you run fan on highest rpm you will notice it, but it’s not really disturbing noise. Overall we are quite satisfied with performance and noise. For the low price you get actually very nice performing air cooler, that can even handle some non-crazy OC setups. The build quality is also very high. There’s nothing to complain at all.
Very silent on lower rpm
Heat-pipe direct touch
Noisy fan on highest rpm
