The trend continues with the Turbo-Cool 1kw breezing through our load tests with only small voltage fluctuations of around 0.05v. I am simply amazed by the amount of power this unit has and its excellent voltage regulation.
This power supply is clearly perfect for any server system or desktop PC with voltage sensitive PCI-E cards. Temperature Testing
A new introduction to the OC3D power supply testing procedures is the testing of heat put into the case by the unit.
Quite often, the cooling methods employed by some manufacturers are inadequate, and result in heat from the power supply finding its way back into your case.
The OC3D Temperature Tester involves placing the power supply into a standard ATX case, and measuring temperatures at various places around the power supply after 30 minutes at idle and full load on the OC3D PSU Tester.
Ambient: Room temperature taken approx 10ft away from testing equipment.
In: Temperature taken 5" away from the PSU ventilation grill inside the case.
Out: Temperature taken 5" away from the PSU fan at the back of the case.
We can see here that the temperature inside the case compared to ambient varies by 1.3°C. This would imply that the cooling method used inside the Turbo-Cool is very effective at removing the heat from the PSU's components and expelling the heat out of the back of the case.
At present Overclock3D doesn't have the correct equipment to reproduce accurate stats on the dBA output, so for the moment you will have to rely on my ear :)
Right from the word go the fan installed in the Turbo-Cool was clearly audible. Comparing the noise with some fans installed in my machine, I would say that the noise emitted was around 34dBA.
Under load the noise didn't appear to increase by much, which would suggest that the fan has been set to a speed capable of cooling the unit under most load conditions.
Check back on this review at a later date for professional noise level testing results.
