The company's new PSU features fully modular cabling and a "silent" design.
Following on from its earlier teaser, Enermax has unveiled its new fanless 650W PSU that is 80 Plus Platinum-compliant and offers 94 percent efficiency. In addition to its silent design, the unit includes fully modular cabling, DC to DC switching and four 6+2 pin PCIe connectors that will support 2-way SLI / CrossfireX.
Passive cooling?
Passive cooling?
I think my room noise is more loud than it.
With that in mind, what's the point of a fanless PSU?
Are there really people having sound issues with their psus?
Also don't use the fan if the thermal load is below a certain point.
Best of both.
Completely fanless PSU makes me think about how much the heat will degrade those parts over time (even if they are extremely high quality components too much heat will lower the lifespan of any of them) and worry about if for those people, like me, that live in a hot place (completely at the middle of the eath where we have 2 seasons, Hot and HOLYMOTHEROFGOD THE AIR BURNS ) these kind of PSU are actually relevant
seasonic(for the semi passive part)
Semi Passive has big problems , if your power usage is in the "critical" area where the PSU starts up the fan , it will switch on/off like crazy and very annoying.
I prefer it to be user controllable ... that is , if it happens , the user can turn off the semi passive controller.
With such high efficiency (assuming real-world efficiency is as good as its certification claims) and what is probably a pretty good cooler for it to be passive, I doubt that even hot areas in the tropics would cause temp issues.
When you're doing home recording, for example, you'll probably want to make sure that your PC's noise falls below the noise floor the room you're recording in. And since time in a proper recording studio nowadays is as expensive as a fanless build PLUS the audio equipment required for the task... you see, there is a point.
This is more of a novelty item for the normal user. I don't know if there could actually be demand for a PSU with no fan.
not all people have equal hearing. some can't even tell if they are listening to AM or FM radio or can't hear at all. people with hearing deficiency are often not even aware of their condition because they can hear conversation (most of it) but don't hear things above certain frequencies (12-12 kHz). noise is usually high frequency and in certain setting (urban for example) there is always some noise (traffic, etc.) which after while people tend to learn to ignore.
all fans make noise. the level of noise increases over time because of wear of the bearings etc. people that frequently upgrade PCs are less likely to experience "jet engine" noise. making fanless design means that:
- it will NEVER make noise (even in 10-15 years if you still use that machine)
- it will not collect dust
- this is clear benefit for certain applications such as recording (ever tried to record sound on a laptop using built in mic for example?)
- better efficiency means less heat developed (product runs cooler) and less energy is wasted
In fact the idea is to use it in completely fanless builds or to have just one uber-silent fan (e.g. over the CPU).
When you go with a fanless PSU, you are essentially taking the 120MM fan from the PSU and moving it to one of the panels on the case where it is closer to the outside of th case and thus louder.
(with a quality PSU, you can get overall less noise by having it have it's own fan, and then having just 1 other fan in the case, then having to put 2 or more fans in the case to maintain the air pressure needed. (also when the PSU is placed inside of a case and the side panel closed, the PSU's fan noise is mostly contained, and thus it generates less noise outside of the case than having that same fan mounted on the front or side of the case).
Exactly. Fans always make some amount of noise, you can even hear the air they move around when they spin up fast enough. If you start switching to passive (or "uber-silent") cooling, at some point the psu fan will become the loudest thing in the system.
simple fix, just buy a fan less PSU and attach an adjustable case fan problem solved.
The sound of my breathing is louder than my PSU fan. When I first installed it I had to check the bottom of my case to see if the fan was spinning. (Monitor not connected as that time)
