![]() ![]() Also, the fans are (much) smaller than competing units, and thus have to run at higher speeds to compensate. Third: The use of two fans allowing them to run at lower RPMs. The majority of airflow is bottom-to-back, no matter the (ATX) PSU. But those are few and far between - and it really doesn't matter. Sure, some PSUs have holes and openings allowing some air to spill inside the case. It takes in air from the bottom, and exhausts it out the back. Secondly: How on earth does this affect cases with PSU shrouds? It has exactly the same airflow pattern as every other PSU on the market (as it needs to to be ATX compliant …). And with a 100mm intake fan, that PSU looks pretty weak. They increase static pressure, so air might flow better through densely packed components (which is the argument for push-pull setups on radiators), but airflow will always be limited by the amount of air taken in by the intake fan. First of all: unless both fans are intakes (with somewhere for the air to exhaust), two fans do not in any way increase airflow. Sorry.” Sixth: Where on earth is the journalism here? Shouldn't journalists actually question the veracity of claims like this? This is just PR-BS regurgitation. With this design, there is no automated ‘best of both worlds’ setting, like 99% of PSUs. It pretty much says “you can have a hot, silent(ish) PSU, or a loud, cool one. Fifth: The addition of a fan speed control knob is a dead giveaway. Even if your PSU has components mounted on the bottom of the PCB, using the casing for heat dissipation, this doesn't matter. Fourth: “cases with PSU shrouds stifle air flow through the PSU compartment.” And so what? What does it matter if you have airflow past the closed-off sides of your PSU? Not one iota. Two noise sources at the same dB(A) level next to each other add up to roughly 3 dB(A) more than either. ![]() ![]() The new PSUs provide stable output with multiple safeguards including OVP, UVP, OPP, OCP (+3.3V/+5V), SCP & SIP. Being 2013 ErP Lot 6 ready, these new PSUs consume under 0.5W in standby mode and use high efficiency +5Vsb circuitry (when combined with a compatible motherboard). Users can boost air flow in chassis without a PSU shroud by switching the orientation of their REVOUTION DUO, as pictured below.Įnermax REVOLUTION DUO dual-fan PSUs are 80 Plus GOLD certified and provide 87-92 per cent high efficiency performance at 20-100 per cent load. The default FMA setting adjusts the speed of the pair of fans depending upon the measured thermals. It also leverages its patented FMA (Fan-speed Manual Adjustment) function to provide optimal cooling upon user demand. As mentioned in the intro, Enermax employs its patented Twister Bearing fans. DUOFlow is said to be a quieter solution than a single fan PSU as the fan pairing can rotate more slowly.ĭUOFlow PSU cooling combines an 8cm and a 10cm fan to draw air into the PSU body and expel it, creating ample air flow over the heat generating components within. Such cases are great for cable management, and for a neat and clean build, says Enermax, but they stifle air flow though the PSU compartment. The new PSUs use a pair of patented Enermax Twister Bearing fans in a DUOFlow configuration to help shift air and keep your PSU running cool for long-term stability.Įnermax says the return to dual-fan PSU designs was deemed a necessity due to the increased demand of PSU shroud cases. It has created three of these new dual-fan PSUs rated at 500W, 600W, and 700W and they are all 80 Plus GOLD rated for efficiency. Taiwan's Enermax has just launched its new REVOLUTION DUO Power Supply range. ![]()
