Upside down power! Options

[Oscar40]

Thanks for the interest everyone,and thanks "Hitman",the manual says it all !
Isnt it funny how everyone looks at things in a different way,this is fine,but basic principals allways apply,if a device is air cooled it needs an air flow to function correctly,sure it will work blocked off but its life will be shorter,Doc......

[Caelum]

I'm building a new system now in the Fractal Design Arc Midi. The vent and filter for the PSU are decent enough so the fan's facing down. The case is a lot cooler than my previous build, so it could handle facing up as well. It'll live on a desk so there's really no issue either way.

My last build I used the Cooler Master CM690II (and the CM690 before that). They've got a bottom vent for the PSU, but the filter isn't as good as on the Arc Midi. I still had the fan facing down without any issues. The environment and air flow in the case are more of a deciding factor for me.

The real question is "Let common sense prevail",trouble is its not that common these days,:-)

No, the real question is, where is your question?

[darklife41]

Like I said, many ignorant posts from ametuer builders. And still, no one has yet to mention a PSU overheating from being placed fan down in a case without holes on the bottom. All insults aside, I believe I've proven my point.

And Caelum is obviously an egomaniac who feels that the few times people have agreed with him are necessary to have in his signature. :-)

Sorry darklife, call me lazy, but I couldn't be fucked reading your wall of text.

What is it you're disagreeing on in this thread? I'm having trouble figuring it out.

[darklife41]

The hilarious arrogance of darklife's post is a joy to behold. Especially since he's arguing against himself - there's a difference between "good cases have a PSU at the bottom" and "a case is only good if they have the PSU at the bottom". Bad interpretation leads to stupidly arrogant and long post. Kudos!

It's not just here.

How could we mere mortals ever hope to understand his needlessly complicated misuse of the IPv4 address space?

Right, read that entire thread. After saying I was researching to see if they'd work on our system, I was plastered with posts saying that it would work with basically any situation. Did anyone ask for further details before giving wrong information? No. They assumed that they know it all, as usual per Atomicmpc forum regulars. I don't really mind having spent the time researching as I enjoy learning.

Now they assume I'm giving IPs accurately, which I was just listing examples.

The egos of some never cease to amaze me. Flame others in order to feel better about yourselves, and remain ignorant in the process. Not exactly the forum for manners and help that it used to be. :-)

The entire point of your post was to insult. So... you've proven... you... take a lot of words... to poorly... insult people... by ignoring... what they said... and substituting... your own... interpretation?

My point was summed up in 2 sentences. I'm too lazy to quote it, but basically: Do you think expensive PSU manufacturers would design their PSUs to overheat and fail, knowing that they'd be place fan down in many cases without holes in the bottom? Of course they wouldn't.

Most everything else that's been posted on here is moot points, or blatantly offensive rather than informative. But hey, those are quick reads. :-)

Just because none have overheated doesn't make it right.
If I managed to drive to the shops with a blindfold on without killing anyone does it mean I should keep doing it, and tell others to do the same?

Also you may make the PSU louder too as the fans will have to work harder to overcome the extra resistance the air will face getting into it.

Yup. Which is why you railing against no-one to refute an imaginary point and insulting everyone in the process is really, really arrogant.

Maybe there is not a rash of failures because people building their computers, and notice no vents in the floor of the case, turn the fan of the PSU (and rightly so) towards the top of the case. Making a fan suck air through a fly shit space makes no sense at all, and I for one would never face a fan to a solid surface, call me old fashioned.

Read up on how cases should be built with positive pressure. When setup/built properly, there is no starvation of air with the PSU fan down, period. In fact, the fan gets more air than it can force through the PSU. That's why we perform smoke tests, and so did the manufacturers when designing them. The Antec three hundred (and all variants), nine hundred (and all variants), and twelve hundred are all designed for the PSU to be placed with the fan down for good reason, but the build must supply positive pressure to work correctly.

You have an opinion that this is incorrect, but no evidence to support it.

I'll add my own opinion, that the manual specifies that the PSU can be placed either way (knowing if it's done properly there are no problems), but suggests that it's placed fan up (knowing that idiots will not build the case correctly with more fans blowing in than out). :-)

I'm not going to call you anything. And I'm not arguing that what you're doing is "wrong", it's just not necessary if you have positive pressure as those fans can't push more air than (to use your words) "a fly shit in space" anyway. :-)

The OP asked "why?" (fans are placed in his Antec case face down), so I provided a comprehensive answer and pointed out that people who didn't understand how positive pressure and new case designs work were contributing bad info to the thread based upon opinions instead of facts. Ignorance is not an insult. Ignorance is: the condition of being uneducated, unaware, or uninformed.

If uninformed people choose to see that as an insult, that's their problem. :-)

When I read that I take it to mean they are saying the holes will allow you to install with the fan up or down, but they say install with the fan facing up, and even supply a picture showing thus so there can be no mistake. If the makers intended it to be a positive pressure setup they would have supplies instructions on how to do that to get the best from their product. But they did not !

There are no holes on the bottom of that case. You take it your way, I'll take it mine. We both interpret things according to what we've learned through our lives, thus interpretations will always vary. :-)

You stated : These cases are designed to have the PSU mounted downward for a reason.

The manual for the case in question states : Note: Power supplies will need to be mounted so that the PSU fan is facing the top of the case. Nine Hundred Two V3 provides mounting holes for power supplies with standard mounting layouts to be installed upside up or upside down.

You talk about manufacturers doing research and that people should take advantage of their design decisions, well in this case (lol!), it's pretty clear.

[SquallStrife]

Right, read that entire thread. After saying I was researching to see if they'd work on our system, I was plastered with posts saying that it would work with basically any situation.

No, they said it would work between computers both joined and not-joined to a domain.

You neglected to mention your two computers were on separate non-routed subnets.

You then went on to vehemently state that it was because of domain membership that it did not work, which is a complete lie.

Did anyone ask for further details before giving wrong information?

Why should they? Based on all the information you gave, the answers were correct.

Now they assume I'm giving IPs accurately, which I was just listing examples.

Why would anyone assume otherwise?

The egos of some never cease to amaze me. Flame others in order to feel better about yourselves, and remain ignorant in the process.

You with-held (deliberately or not) pieces of information vital to diagnosing a network issue, then looked down your nose on everybody else because they didn't assume you were trying to link two computers on two networks with no route to each other?

Edit: Then in this thread, you went on a several-paragraph tirade condescending people with slurs like "ignorant" and "amateur", when it would have been quicker, earier, and more forum-ly to say "In my experience, if you have a positive pressure setup, it's safe to have the fan facing down".

You're not one to talk about ego or ignorance.

If I wasn't familiar with your constant misuse of terminology and failure to grasp even the most basic concepts, I'd say you were trolling.

I'm still not sure if this guy is agreeing with me or not.


He seems to be doing both. On the same point.




I dun geddit.





Wait, I haven't even made any points. Tantryl suggested what i said was implying a point, or something... and then it appears that darklife has then extrapolated that to mean a whole bunch of other things... I... But...




I just said my case has holes in the bottom of it :\



I DON"T UNDERSTAND WHAT IS HAPPENING HERE.

Protip: Not all power supplies have top (or bottom) mounted fans.
