So MarkF was lying?
Thanks.
No, he was not, you did not specify that it was a computer fan, he may not have much experience with computers and as such assumed you were using a brushed DC fan, which can be reversed by switching the polarity.
Monkeh says u r lying!R u?
Thanks.
Is this trolling by MarkF something that is tolerated here?Im quite shocked that no one seems to be offended by this.
And u should stop telling others what they should prefer!Idiot.
Thanks but im not talking about CPU,but directly from the PSU.(6 pin)
After reading the latest comments and thinking about it,it is quite clear that this forum is not at all what i thought it was!
If people can can just say things that will result in damaged/broken devices without anyone even being bothered by it,im not comfortable taking advice from anyone here.
I hope this will be cleaned up...
This barrage of messages was over a
14 minute period, this is NOT live chat, you have to give people a chance to respond to your questions. Nobody was offended at
@MarkF, but I am sure many, including myself, are offended by your impatience and name-calling. This forum is full of patient and mature people very willing to teach and IMO is one of the most friendly places on the internet. Don't let my admin status fool you, this is not my forum, I am simply a forum member what helps Dave with server management, which I do out of my own pocket and time because this community gives so much to people like me that want to learn.
Also on the actual topic, a brushed fan (ie reversible) would be a bad thing to use inside your PC if that's your intention. Not only will noise be a concern due to no speed limiting, but electrical noise would be a concern also, the arcing of the brushes on the commutator as it switches coils emit EMI, which could interfere with the operation of your computer. The DC motor would also introduce noise in the forum of high voltage spikes as the magnetic field of each coil collapses unless you add some protection (usually a snubber diode), and as the brushes wear (they literally grind down) fine conductive carbon/copper particles would be thrown into your PC case and could cause shorts over time. Also, a brushed motor wears out far faster and uses more energy.
There is a reason why we use brushless fans in computers.
If you really want a reversible brushless fan I suggest you look at building or obtaining a brushless motor controller and replacing the electronics of a brushless fan with your custom controller, though I believe that this is a bit beyond your abilities at this time based on this and your other threads. Otherwise, it might just be easier to mount two fans back to back and only power up the one you want based on direction of airflow.
