Here are some US prices that I found. I didn't find the Xilence Red Wing fan anywhere. Surprisingly, none of these were on Newegg.

Yate Loon D12SL-12 - $6.99 - www.frozencpu.com
Noctua NF-P12 - $20.75 - www.frozencpu.com
Akasa Amber - $13.95 - www.sidewindercomputers.com
Arctic Cooling 12025L - could not find this exact model but other models in the $10-12 range

Post a picture of the test setup? I'm curious...

Also, any chance of getting pressure testing? How about RPM data?

How many times do you test? Averaging multiple remounting will help account for the accuracy of the instruments.

Excellent!! Can't wait to see more results.

These are what I have left:

Coolermaster A12025-12CB-5BN-L1 blue LED (pulled from a CM532)
Lian Li LI121225BL-4 (pulled from a V1000)
Coolermaster A12025-12CB-3BN-F1 (pulled from a CM Mystique 531)
Xinrulian RDL1225S (no idea where this came from)
SilenX IXP-76-18 (38mm)
Ruilian Sciene RDM1225S (again, no idea where this came from!)
AcRyan Blackfire4
SilenX IXP-74-14 (25mm)

And current requests seem to be:

Ultra Kaze 2000
Aerocool Turbine
Delta EFB1212SHE (38mm)
S-Flex F 1600rpm
S-Flex G (currently unavailable in the UK)
Slipstream 1600/1900rpm

I'm working all weekend so I doubt I'll get a chance to do any more before Monday, when I'll try and get through all of these ones here so I can move onto radiator testing

The test setup is extremely basic at the moment

I'm hoping to get one made up out of wood early next week, and then I'll redo all the tests.

At the moment, I'm using a plastic tub which has a radius of 114mm and a hole cut out the other end the size of the CFM meter, and then I attach both the fan and the CFM meter on with extremely large amounts of tape to ensure no slippage. The amount of double sided tape I've been through is insane!

The plan for the new one is that it will be made out of wood - I want to attach 4 30mm bolts from the inside of the panel so that I can slide the fan onto it, and then screw some nuts in so that it's held in place. The wood will form a box, and I'm still looking at the easiest way to build a simple "tunnel" to redirect air as much as possible into the CFM meter - it's quite small, radius is only about 3cm.

Like I said, I'll be retesting when I get the new box, but these should be pretty close to accurate as the shroud is pretty much air tight

RPM data I'm not sure on; I've got an external fan controller style device which I can plug a fan into and it'll provide 5, 7 or 12V depending on connection. Is RPM data important? If so I can make something which will split the 3-pin connection so it gets power from that device and provides the motherboard with an RPM reading?

I test 2 or 3 times - if the first 2 tests are similar I'll take the average, if they aren't I'll do a couple more tests and take the average of the similar figures

Thanks for all the support so far guys

e_dogg - I'll add them to the first post, thanks

one other thing someone is looking for in tests is static pressure.... just wondering if theres any way to test this with the materials you have available

i just know that this would also be another good thing to add to the testing

prosser13

I don't have the equipment to test anything like that

However, higher static pressure should lead to a lower CFM drop on the radiator airflow test?

Fixed the title for you

I will add this to the Sticky "Air Cooling Essentials Thread".

Thanks for all your hard work

Any chance you could tell me what you use for CFM measurements? Is it one of the Extech airflow meters?
