Fan efficiency

[Onasi]

@Assimilator
No, I understand that, just thought we were talking in terms of practical home applications. From what I understand, our closest theoretical path to it is via quantum, and that sure as hell isn’t something that an average user will have any relation to in any foreseeable future. Just seemed like a weird statement to make. Then again, I vaguely remember some company talking about prototyping a fully reversible processor chip and being ready to actually present it soon-ish, but that particular press release sounded like a typical investor trap bazinga and not anything actually viable. I might be out of the loop on this, granted.

@Shrek
See above.

Got two of these on my PC, but they definitely aren't for everyone. At $30 a pop, these industrial grade fans are extremely expensive even for Noctua standards. They're also very noisy. Noctua manufactures an iPPC-2000 model with IP67 ingress protection rating, I have one of those too. It's quieter than the iPPC-3000, but not by much. To fully populate a large case that takes ~12 fans + replacing your heatsink's fans with these, you're looking at around $400 on them alone.

True that, I have 12 @ 140mm 3000 iPPC PWM and 12 @ 140mm 2000 iPPC PWM on my rad assembly.

At low speed, ~500 RPM, they are not silent, but not very loud either. At full speed, they are pretty loud.

You guys would hate my AFB1212SHE 1.6a fans. 190cfm. They are incredibly loud just at 50% duty cycle. But they can move air through 3 rads stacked XD

Figure they are like 2% energy effecient. (That's a guess)

1.6A fans at 12V is almost 20W, so consumption could really add up if one ran several.

If one were to run several, in the right configuration, and the addition of a gyro, and flight controls you could probably play with it around the house

Please purchase and test facility of vertically mounted drone as cooling apparatus using GPS lock functionality - topically for purposes of determining efficiency.

Yeah, if comparing to a child's night light which most likely is on 8 hours, maybe dusk to dawn, if not 24 hours per day.

Plus, as I said before but you seem to want to ignore, typical users do NOT run their fans at maximum RPM and thus maximum loudness.

So this is just you, sadly, Shrek, once again using some extreme anecdotal what "if" example to try to render moot an entire point that applies to the vast majority.

And I haven't smoke a header yet with it. My kid has one in his case. The other is some random 120mm might have come with the case which had 3, 2 died already, case bought 2017. So it might be locked up, haven't check after the over haul and cleaning a couple months ago.

We don't run it hard. 12400F isn't hot enough during gaming. Pretty sure I manually tuned it because the motherboard profiles are seemingly aggressive, but the POWER of the fan just audible makes the ramp up deceiving. Just when you think it's at 100% duty cycle NOPE. it's got more RPMs haha.

Makes any GPU with a blower fan sound silent.

It is not possible to run it 100% duty cycle all the time. And I'm talking about 1 fan. Haha.

The issue is, I have a hard time finding the data sheet on this particular fan. The one at Delta Electronics site is inaccurate. The sticker right on the fan literally states 1.6a. Their site says 1.0a. The picture of it says .18a...

AFB1212SHE

AFB1212SHE, 120x120x25.4mm, 12 VDC, 1.05 A, 12.60 Watts, 3700 RPM, 2 lead wires, ball bearing, axial, dc fan, delta

www.delta-fan.com

Amazon has the picture inverted, and I can pull a spare out later. But is the 1.6a.

And yes, it can fly like a drone.

I should start a new thread as this is off topic but one doesn't need to go quantum for reversible.

One can make a Fredkin gate with billiard balls.

Oh come on! Do you consider yourself an example of a "typical", normal user? Because I sure don't.

You are not even an example of the "typical" TPU poster!

You have clearly demonstrated you have advanced skills, knowledge and experience, even among most enthusiasts! You don't become a Staff Member/Moderator of one of the foremost technical sites by being a typical user!

So don't play that "" nonsense with us.

YOU ARE NOT NORMAL, DUDE! And that's a complement so be proud of it! And on you for pretending to be insulted.

 

[freeagent]

Haha no no, I am just a regular user.. heck I need help from my wife to use office for my resume

I just like to play with hardware

And yes this was just a joke, I was not at all offended

Also, these fans are fairly quiet, I can sleep next to this system while my wife is sick for a week

I do hate this couch.

 

[ShrimpBrime]

@freeagent. You better just take that complement and run. I've never seen Bill give someone credit like that before!!

 

[freeagent]

Just have to say

Thanks guys

 

[Bill_Bright]

You better just take that complement and run. I've never seen Bill give someone credit like that before!!

You may have never seen it but I do give credit when credit is due. But you are correct - my post was meant to be complementary - even if a bit over the top (for me! ).

Also, these fans are fairly quiet

That's good, but likely a credit to that case's ability to suppress fan noise too. Sadly, many chose a case for its aesthetics and pay little to no attention to function. I first started buying Fractal Design cases because they were lined with sound deadening materials!

Have I mentioned I really hate fan noise?

 

[freeagent]

Have I mentioned I really hate fan noise?

I do too, but I also hate being told what frequency my system should run at, so I try to get the most from it all the time.. being that my system is in the basement, it is almost always cool down here. Either from the frozen ground the extends 6 feet below, or from the A/C when the real global warming starts up in the summer. I hate summer. I'm not even fat, but it makes me feel fat. Like a lazy polar bear. Ugh. Like standing in someone's mouth.

 

[Bill_Bright]

Well, I grew up in Arizona and New Mexico so I much prefer the heat to the cold. I figure if I get hot, I can just shed some clothes and go sit under a tree in the shade somewhere. Do that in the winter here in Nebraska, and you won't ever wake up.

Yeah, ambient (room) temps make a huge difference with computer cooling.
