I think they are both very good at undervolting, but the S-flex has more range low to high.Quote:

I don't have the Sflex G recorded yet, but the F model is up.
These videos come out of my JVC camera at about 220mb a piece! Even with 10MB cable, it take a LONG time to upload to youtube.Quote:

Alright, I've got all 5 videos I created last night uploaded.
Taking requests on the next priority videos...thanks!
Martin

So I've just used your comparison method martin (useing 2 videos @ = CFM)
the Gentle Typhoon @ 9v/20CFM is SO much quieter than anyof the other fans..... amazing.

@ 30 cfm the sanace beats the GT though IMO
Yeah, 9V seems to be a nice tone, 10V is a little annoying, then it seems to smooth back out at 11-12V.Quote:

The videos are working really well for this, something I couldn't do when testing, but now you can match up the CFM and make a good comparison..I like it!
This also takes the burden off of me trying to make judgment. As long as I keep my video recording setup exactly the same, it should be a good way to let the users decide for themselves.
thx martin when i heard the GT it was like motor spinning
i found the scythe sflex f louder for some odd reason
i like the noise from the GT it sounds cool :D and the fact its sounds a bit quieter
Very nice ... good way to show the noise levels.
It's very interesting ... even though the noise may be lower, I found the GT a bit annoying above 9V ... Next time I listen to these, I'm going to do it "Blind" so I don't know which fan I'm listening to - just to remove any unintentional bias (e.g. - I own the S-Flex, and don't want to switch :p: )
Nice. Never thought I'd get a good impression of sound level from a youtube video, but the S-Flex video was very close to what I hear from mine. Not sure why I find that surprising, but I do.
Anyway, thanks for doing this. I love graphs and numbers, but this was an awesome idea, IMO.
This is really good martin!
I'm glad you went with the 10 seconds at each volt from 4v to 12v. And also that you included CFM. It was a pita to check the graphs every time :D
I agree that the GT is VERY good up to 9v but then it almost gets beten by some other fans. The SA have a rattling noise to it. Don't like it at all...
Maybe the 1450rpm version is just right (9v gives 1350rpm on the 1850rpm version)
now you just need to get your hands on some lower GT's like the 1450 version and 1150. I just orderd a S-flex F (1600rpm) and a GT (1150rpm) so ill probably have them in 2 days. And I'm going to check it out for myself. They don't have the 1850rpm version of the GT in sweden so i hade to go with the 1150.
Does anyone know were I can get the full range of GT's? I know ppcs have them, but ill think ill stay away from them. I know RRR had some real issues with them :\
which fan do you think sounds best martin?
While some people report having problems, there are plenty of people who haven't had an issue. I've had excellent service from them during the past 3 years.Quote:

and to answer your question - newegg sells the full range of GT's

I can tell you for sure that he has no sort of agreement or sponsorship from sidewinder computers.... there was some recent "drama" over this and I asked gary for clarification about it and he said that RRtech is in no way shape or form sponsored by his shop.Quote:

Still trying to figure that out myself, but anything below 1000 RPM is pretty good..:DQuote:

It's a hard thing to judge with the higher performing fans, because you generally relate to their noise level by how much noise you get at 12V. Trying to put that apples to oranges misconception aside and compare per CFM produced takes a different way of thinking.
The GT obviously has my attention, but I also want to spend some time with the recordings after they are done and compare the bottom end of some of the stronger fans. The dB numbers seem to indicate some advantages to 38mm fans that I want to look at more closely.
Unfortunately it's going to take a little while to get the video recordings done since I can only get them done late in the evening when the stomping feet and noise makers are in bed. It's amazing just how hard it is to find quiet when you need that for something.
Anyhow...I'm not completely sure myself yet. I just figured I'd keep collecting the information and with the videos...hopefully that's enough that you guys can make some judgements as well.:up:
hey martin didnt you find the GT queiter at 12v then the s-flex?
i personally like the cool sound from the GT
wow! GTs are expensive here in canada. 16 bucks a pop. I'll stick with my 7 dollar slip streams.
wow so according to the chart for cfm/dba the cheaper UK3 seems to do much better than my San Ace across the board. Just too bad they are sleeve bearing for the application I was going to use them for. I wonder what kind of temperature difference I would see at different CFM's to determine if I should be switching to the GT's, I can sleep 4' away from my 3 San Ace going full blast no problem, but still.
yeah, I can sleep 2 feet from 3 sanace @ 70% and 3 YL-H @ 70% no problem.Quote:

Yeah it's quieter, but it's also a different tone. I get more of a combination of wind with motor sound from the Sflex's, where the GT is almost absent of the wind/blade noise, so all you hear is the motor. I like it, but some people may not.:shrug:Quote:

I think the UK3 has a more pronounced motor tick than the San Aces, but it's hard to tell when the tests are far apart. Hopefully the recording will make it an easier comparison.Quote:
