Fan Testing Part 2 (Retesting + Noise)

[Eddie3dfx]

Martin, you are spoiling us once again. Thank you for taking the time out to do this.

[SNiiPE_DoGG]

Just interested, maybe it has been said before, but when the GT-15 is running @ 9v 20cfm in the video, what is the rpm of the fan?

If you check the graph you can see its running about 1350rpm at 9v

[SNiiPE_DoGG]

damn that was hard to spot, good stuff though, thanks

[Brodholm]

Yeah Some are kinda hard to spot.

And I think that it is very nice to 9v (1350rpm). And martins fan only went to 1750 (1850 version) so i think that at 9v it is like the GT 1450 version. Well I hope that the GT 1450 is even quieter at the same rpm. So I'm hoping that the 1450 will be the ultimate choice if you want silence and good performance.

I have the 1150 coming in later this day. (they don't have the 1450 and 1850 in Sweden ) Maybe ill do some filming myself. That is if I find my camera

Nice! Post your thoughts on the in person test. I think the videos help alot, but there's no replacement for actually trying out a fan for yourself..

The lower speed GT's are on the top of my list to try, but I probably won't be doing that anytime soon. My plan is to finish up this round of fans this week, and then test a couple more donations that come in here a couple weeks from now. Any spare $$ I've got right now is going towards some rebuilds of my wife's banshee and my dirtbike. So the bikes will be getting priority for a little while, but I'll keep this test setup the way it is for some future tinkering.

FYI, added the koolance fans, they are very good as well. Check out he sound on the bottom end and let me know what you think.

"Post your thoughts on the in person test" Is this some thread or what

Too bad on the lower end GT's Because I cant get my hands on them here in sweden. And Ill have to order soon. But I guess that they only get more silent the lower they go in rpm or stays the same. I think I will have to take chance and order some 1450

And I listened to the Koolance fans and they don't even come close to the GT. It is totally killing all the competition from the clips i have compared. And it really have a nice sound to it. Especially at the low rpm's (<1350).

[Freaky Freezer]

Just listened to the Delta. You cannot tell me that vertical takeoff would not be possible with enough of these. Insane. I commend the people who listen to that while working on their computer

[Brodholm]

Just got the fans!

Tried them right away. What i found was that the GT 1150 was very silent even at 12v (no rad) and the S-flex F rather noisy. And I also tried a Yate SL from petras. At 12v the SL is much more noisier compared to the GT 1150. But the GT have that high pitch hum to it. Not as much on 1150 rpm but with the 1850 martin recorded. But what i found out that was that if I took the fan from the table and held it in my hand it disappeared! And also if I put some rubber or anything that could act as a antivib material it was gone. So I think that the sound comes from mounting without antivib.

Martin did you use some kind of material to act as a anti vibb when you mount the fans? If you aren't using that the fans will get even quieter. Try holding the GT 1850 in your hand and try!

So far i have only gotten good impressions from the GT!

[Sparda]

I want to try some too but cant find any high speed GT within european continent..lol.

[Brodholm]

Yeah, The highest I could find was 1150. I asked tom at chilled to get some. He replied the following: "I'll see what I can do... I doubt we'd take the whole range, maybe the 800, 1150 and 1850"

I told him that id rather see 1150, 1450 and 1850. At least I'm most interested in the 1450 version. And I see no need to go below 1150 since everyone uses fan controller these days. And that the 1150 is almost silent at 12v.

ppcs can ship worldwide although i dont reccomend it because they will screw up the order

i wonder what the koolance fan 25mm (high) cfm to rpm is compared to the GT ap15 cfm to rpm

[SNiiPE_DoGG]

Where the hell did you get that ridiculous idea? oh right, from the real banned raider himself. Leave his BS on his forum thats why he has it.


lemme tell you this - I have spent over 12,000 USD with performance PCS over the past 3 years and not ONCE was an order "messed up" or even damaged. Hank is an exemplary retailer.

[Sadasius]

Damn beat me to it. Ppc's has always been pretty good to me as well. Have made many orders with them and they have made only one mistake out of all of them which was minor. They sent me a blue LED fan when it was supposed to be red. Next shipment it was there and I still have the blue one too.

I've also had good experiences with him, but his score on ResellerRatings.com over the past six months is quite a bit lower than most of the other popular custom PC parts retailers. (Though to be fair, his lifetime score is right up there with the other shops)

Six Month Ratings:
PPCs - 7.83/10
FrozenCPU - 9.53/10
Sidewinder - 9.83/10
Jab-Tech - 10/10
Petra's - 10/10

Lifetime Ratings:
PPCs - 9.46/10
FrozenCPU - 9.42/10
Sidewinder - 9.79/10
Jab-Tech - 9.63/10
Petra's - 9.97/10

[Brodholm]

yep, after reading a bit about ppcs I'm not that worried about ordering from them. RRR seems to have a real issue with them though. He is totally berserk about it. But lets leave that alone in this thread as admin said earlier in a post.

The issue is that shipping is a from the us if you live in Europe. They will add taxes and stuff. Thats why it whould be so great if tom @ chilled could get some! You guys should mail him to!

[SNiiPE_DoGG]

For EU guys, contact specialtech.co.uk I hear that they will order pretty much anything you ask them to and start stocking it. If a few of you asked you would be guaranteed

what about 140mm fans? 140x51mm sanace?

No, mine was a direct mount. I felt this was the only fair way to reward the fan makers that included some sort of antivibe frame. There's definately some substantial gains to be had with a good foam gasket, I prefer the custom made type from 1/8" sticky foam myself. And before anyone asks...No I'm not going to retest them all with a gasket, my wife has already been nudging me with impatience to get these test done. It just so happens that she likes to wash close in the evening when I need to run tests and the two conflict. I've been having to shut down the washer/dryer to do that, and she's quickly running out of patience with me..

@ Martinm210
What anemometer are you using?

It doesn't have a brand name, it's one of the cheap Ebay anemometers and cost under $100. I wouldn't trust the numbers from an absolute perspective, but since they were all tested with the anemometer in a fixed location and they were all using the same duct calibration area, they should be pretty good for relative comparisons within a couple of CFM is my guess. Also only good for 10CFM+, anything below that is not trustworthy.

what about 140mm fans? 140x51mm sanace?

My test rig is only setup for 120mm fans, and I'm not testing anymore than I currently have for now. I have a couple more donated fans coming and I "May" buy some for curiosity sake, but I'm not taking request for which fans to buy. If you really want me to test a particular model, I'll consider that if you pay and send me a sample. I'll donate my time that I have, but I'm not donating my family's budget for others curiosity. Sorry.

Leave his BS on his forum thats why he has it.

Agreed, please leave discussion of banned members for PMs or emails, I appreciate it.

Here are two more fans uploaded, I got about 10 more recordings made last night.

"martin its me or the fans" just kidding of course. Its REALLY appreciated the things you do for this forum! As said before, you are spoiling us

I think ill be using some rubber mounts like these:


And I hope that the high pitch will be reduced.

When you make a comment like you did above, you should base it on your own personal experience, not someone else's, especially someone with the character of the unmentioned. If PPC's ever screws you, tell us, we would like to know and we would all find the information useful. But no one cares about what so and so said happened to him, once again, especially when most of us know what kind of person so and so is.

For the record, I've ordered the majority of my watercooling products from PPC's and I never had any more problems with them than I did with the other major watercooling stores.

these videos are sooo distracting me from studying for my finals.... and pissing off my girlfriend at the same time

I love it! great work martin , and I am sorry I had to take the thread off topic again

Haha, I can see it now...probably the same look my wife gave me when I turned off the dryer last night so I could record some fan noise..lol!

No problem...it's all good, and carry on with the noise....

[SpuTnicK]

Great work, Martin
I've watched almost all the 38 fan videos. According to your anemometr fans take places from quit to loud:
1 koolance 12038hbk -the most quite
2 ultra kaze 3000
3 san ace h1011
4 delta - the most loud one
Couldn't listen to panaflo m, some server error...
Can you please redo san ace test. It looks like the distance from your anemometr to the fan differs from the other ones in videos. I thought SA H1011 are number one by noise among 38 fans, aren' t they?
P.S. sorry for my english

The anemometer is just the digital indicator, the actual vane probe is fixed in the box inlet, so the numbers are accurately relative. The volt meter and anemometer box are just sitting freely, but they are wired to the correct/fixed locations..

My bike parts are likely coming in tomorrow, so these recordings will have to do for a while. I've got an itch to go fast, and these fans just don't cut it!...

I'm supposed to get a couple more fan samples in a few weeks here, hopefully by then I'll have the bike rebuild all done and I'll get a chance to play around with the fans again for a while. So, I will be saving my fan test box the way it is for later..

[sgayol]

Is there a vid of the panaflo U coming? I'm really curious to hear the difference in sound between it and the UK3! On paper there is a lot of similarities...

Also, I have a bunch of UK2 fans collecting dust. PM me if you're interested in having 1 for testing...
