Fan Testing Part 2 (Retesting + Noise)

[Silverhawk]

Has anyone considered taking this data and making it a web form where people can select the fans they wish to use to compare? Something like how storagereview does it with harddrives.

The delta 25mm FFB1212EH at frozen are quiet and can levitate when turned up all the way. These things move some serious air but you'll need a beefy fan controller that can handle at least 30watts per channel. At 25mm there are no better fan in terms of CFM... At a little under half way the noise is nominal but still you'll hear it -- a fair trade off for the performance IMHO.

Quiet is a relative thing!

Can you make a recording, then the listener can decide.

No sign of the 2150rpm Scythe GT's

Just bumping this thread

bump....bump.....

Here is a video of the fan in action. No real attempt was made to get an accurate recording, but you can make a good judgement call on the "quite" factor from it. http://www.youtube.com/watch?v=XbD7MK12buY

While its not near as loud as some bigger, better Delta's, it is still way, way, WAY, louder than something like a GT 1850. But moving 150CFM per fan, I would expect it to be pretty loud. I bet it would be a great fan for a "monsta" rad if you just dont want the noise of the more powerfull Deltas.

thanks，just need that

I've got headache after trying to read those colorful charts. But good work.

Would it be possible to put this thread at Sticky. Because it gives all answers you need when you are choosing fan for the WC. Just idea, no need to do this.

Um. . .it is.

Ok, I just saw it. I`m new in this forum, so sorry that I bothered. Need to read more carefully those thread headings.

This is excellent! This is what I like to see. If I had the resources I could do this type of testing all day.

I was looking at getting a Panaflo FBA12G12* and did not realize that the 'U'(20-35CFM @ 1;05-1:26) would click like that when throttled down compared to the 'M' (20-35CFM @ 1:22-2:00). I was wondering if that is usually the case of high speed fans throttle down with a controller vs. a lower speed version of the fan at the same RPM/CFM or if the microphone used was exaggerating it.

I need 2 or 3 fans and wanted to try either the Panaflos, Thermalright TR-FDB or SanAces (if I could get my hands on one) since I could throttle them back when I want the system quiet, and still have pretty good airflow. These would be used in an Antec 300 and on my Noctua NH-U12P (where I see no difference with Push vs Push/Pull setups because there is a 140mm fan a couple inches away). The Gentle Typhoons look great as well but do not have the potential to move as much air as the other fans I mentioned.

Would it be fairly accurate to assume that at the end of the day the difference between a case that sounds like a jet turbine and a fairly quite case with GTs be maybe 5C at most? If so I'll just go for the GTs because that clicking gets on my nerves.

Nice result from the update Martin, I still like my San Aces better than my GT.
