Thank you, thank you. It isn't completely clear but this video was part of a review on my website and have since gotten a little better with my editing. You are correct about the decibel meter, it would have been the trifecta of relevant information. I might add one in the next installment however, sound level and quality changes based on proximity of the meter and what is around the fan. eg radiator vs open air, grills on a case etc.. Because of that I decided to rely on the mfg tested dB number and focus on what was really important, at least from a performance standpoint. Thanks for the sub!! It will be a slow build but I'm working on more.

This video was actually part of a review I posted on Hardwareasylum.com so it would be a shame not to test the different profiles. I even have a handy chart on the site showing the differences between them all.

Ty, I need to revisit this project as I have a few more fans to test :)

@@Hardwareasylum can you please test some thermaltake fans? ^^

That shouldn't be a problem. I have a few more I can run though.

@@Hardwareasylumthanks! Im looking into buying those riiing 12 rgb and I need some with a high static pressure.

I'm glad you found it entertaining! I am actually working on getting some more fans to test, The Corsair fans might be the most relevant given how "popular" they are with the Reddit/KZfaq crowd.

So, basically, you are trying to build a mini swamp cooler, that seems easy enough. However, I cannot comment on what fans to use but, the way I see it, everything I did in "this" video could be adapted to your project. Thing is, I was simply testing some computer fans trying to illustrate that the fan specs are generally correct, you just need to know what to look for. For your project, you're going to want something like a delta PFC1212DC and hook it into a fan controller and don't forget the fan grills as it WILL suck up your cat.

I'm glad you liked the video, I have a few more planned using different fans along with some lighted versions. As for a fan recommend, you cannot go wrong with the Air Balance it has the best of both worlds and with the speed limiter you can dial in how much cooling you need.

I'm glad you liked the video. The fans I used is not an all inclusive list. really more what I had laying around the lab. Noctua is great when it comes to fans and sometimes it is simply knowing they exist.

It's a freaking jet loud imagine sitting next to it for hours

More vids, Yes. Everything else. Uhh NO. I will give you an A for effort though. Your suggestions are rather specific and do deserve a response. 1) most microphones won't be able to pick up fan noise at any level that you could make a decision on. a dB meter would be best however cost prohibitive for one with any accuracy. 2) Testing fans at the same RPM is pointless. Fans with a similar blade profile will have similar specs (flow/noise) at equal RPM points along the curve. That might work with dissimilar fans however, see point 3. 3) I currently don't have a way to set a fan to a certain RPM with any repeatable accuracy in the context of this testing method. I do promise that future videos will include some different information. This video was actually part of a larger article on my website. You might what to check it out. www.hardwareasylum.com/reviews/cooling/cm_masterfan-120/page4.aspx

The fan in the video is the NF-F12 www.hardwareasylum.com/reviews/cooling/noctua_nf-f12. The NF-A12 wasn't released until two years after this video went live. I have been meaning to revisit this topic with some new fans and will be sure to put the A12 vs F12 in there.

That is actually a very well documented fact and the primary reason the F12 was created some 8 years ago. However, the focal fins don't have much effect on radiator cooling. The test here is purely on pressure. Where you will see the difference is pressure at a distance aka case cooling.

That might actually be fun. Interesting story I used a pair of those fans once for 4-way SLI overclocking, sadly they were borrowed so I'll have to pick up some new ones.

Appreciated, now I just need to post a few more videos.

I'm working on a part two that should go more in-depth into what makes a good fan.

Yes, this video is quite old and, I believe some of the information you are looking for is on the supporting article for this video. The article translates the fan flow into system cooling which then can then be calculated. The rest if just simple math based on the defined variables.

@@Hardwareasylum Thanks, but are those fans still available? Would you please organize your videos into different playlists? I can't tell if you've even got more fan tests.

Most of the fans are pretty vintage at this point. Except for the Noctua, that is still a popular air mover. As for organizing the videos? there is only one fan related video on this channel so, there you go. However, there are other fan reviews on my website. Seems I am recognizing a trend here. :) Thanks for watching and writing a comment.

@@Hardwareasylum Thanks for the interesting experiment. I'm pretty sure it's an unprecedented way to look at AF and SP.

Holy necropost TRS!!. and yes, you missed that part.

@@Hardwareasylum where is it then?

Of course you are... That is the reason I setup the test.

@@Hardwareasylum What you tested was airflow not static pressure. you have to put the fan up against a flat surface with several small holes in it to test pressure. Certain blade shapes can move a lot of air unobstructed outside of a case but then you put them in the case which generally will have a metal mesh or screen covering the fan and all of a sudden the fan is garbage cause the blade design was not meant for static pressure.

I'll give you that. However, airflow does play a part in the process. Sure, things change but at the end of the day you still have to push air through something. And, I'd argue that had I put a radiator in there instead of a restriction I would have gotten similar results. (More testing for next time) For the actual review of these fans (The Cooler Master fans) I do test them on radiators and map out the results of the fan testing as they were shown in the video.

@@Hardwareasylum Only people that would say airflow plays a part in pressure and will provide similar results are people that don't understand the difference between mmH2O and CFM. You could have a 150 CFM Ultra Kaze fan (reduce it's speed to 1500RPMs to realistically match other fans and noise output), put it up against a wall and have almost no pressure cause the blade design wasn't meant for being pressed up against obstructions. Then take a 3.0 mmH2O fan that only advertises 60 CFM and have it put out 3x as much pressure and move twice as much air through your radiator. The calculation of static pressure isn't measured by airflow at all because the fan is pushed flat against a plate so airflow will be 0. Fans with low pressure are basically just moving air in a circle instead of through when obstructions are up against it. There's a lot of fans that advertise 80CFM that have anywhere from 1 to 4 mmH20 at 1500RPMs. Everyone one of them will fill that bag up at similar rates until you put a radiator up against it. These fans and the UltraKaze are the ones I've used in the last 15ish years. The best being the top two in the pic. UltraKaze was a joke unless running max RPMs and it died super fast (however it would have filled that bag in a fraction of the time): i.ibb.co/jynvsP2/27858674-1788276124557516-3939125916088125000-n-1.jpg

Not in the least. I was considering another series of videos, like this one, that explore some of the more exotic fans that overclockers use. Now those are fans not to fuck with.

NOCTUA industrial 3000rpm also quite good

For you... No. Not only is this video over 7 years old but it was created as a supporting presentation for the written article on my website. THAT article has the charts you were looking for while the video was just a visual demonstration of how the fans were tested. I find it amazing how often people get upset when they misinterpret a KZfaq video because they were too lazy to actually look for something.
