For the purpose of this review I will be testing the Zerotherm Nirvana NV120 Premium with the following system.
AMD Phenom 9750 @ 2750mhz.
Xfi Extreme Music
4GB Team Elite
Seagate 80gb x2, Samsung 250gb
Samsung SH-S183 DVDRW
OCZ Stealth Xtreme
Zerotherm Nirvana NV120 Premium
To test the Zerotherm Nirvana NV120 Premium I will run the above system at idle and full load (running Orthos prime) for approx an hour to let the temperatures settle.
I currently have a Zaward Gyre CPU cooler fitted so I will be comparing the Zerotherm Nirvana NV120 Premium against that. Once I have run the tests on the Zaward Gyre, which is a VERY capable cooler so the Zerotherm Nirvana NV120 Premium has some real stiff competition, I will then rerun the tests with the Zerotherm Nirvana NV120 Premium cooler fitted. I will also take readings from the PWMIC to see how well the coolers cool the chipset too as the case IS a multimedia case and as such has limited system cooling to keep noise to a minimum.
Temperatures for the cpu will be taken using Lavalys Everest and the PWMIC temperatures will be taken with Abit EQ, as this temperature isn’t reported through Everest. I have chosen to include the PWMIC temperature as I know from experience that under load with insufficient cooling the PWMIC’s can hit dangerously high temperatures. Also we will provide the results in Delta format, which if you dont understand can be explainded HERE
Once I had got the results from the Zaward Gyre I set about installing the Zerotherm Nirvana NV120 Premium. First I fitted the AMD retention mechanism, which was a simple job, which just required it screwing on to the base of the heat sink.
Fitting the Zerotherm Nirvana NV120 Premium to the CPU / motherboard was slightly trickier but still only took a matter of minutes and required the retention mechanism fitting the opposite way round to how I originally fitted it. Once I had done this it was a lot easier to slot it past the chipset cooling and clip it on the retention clip on the motherboard.
As you can see in the dark it is illuminated by 2 blue LED’s so would make a nice addition to any “Blue” set up.
Results as follows. As the Zerotherm Nirvana NV120 Premium has a 3-pin fan with separate controller I have taken two sets of readings from it, at both low and high fan speeds.
Room temp whilst testing was 23c.
Power Managment results are left default, Only CPU results are in Delta Format.
Delta Temps Explained HERE
With the Zerotherm Nirvana NV120 Premium set to its lowest fan speed I had to cut the load test short as insufficient airflow was being passed over the PWMIC’s and they hit dangerously high temperatures, approaching 100 centigrade. The CPU cooling is perfectly ok at this speed so with another means of cooling the PWMIC’s you could run a near silent set up under full load.
With the fan on full speed, which is definitely audible but not overly annoying in my opinion, it performed very well cooling both the CPU and PWMIC’s better than the Zaward Gyre, which is itself a very good cooler.
All in all a mixed bag of results as the Zerotherm Nirvana NV120 Premium technically “failed” at low speed as had I left it to complete the 1 hour trial I could have ended up in a dead motherboard.
