The Tricod is just a Yate-Loon rebadge. I'll do a 5v test for you when I next can.

That was one theory that I had too, but was unable to find anything in theory or practise to back it up. Convection efficiency is always increasing with increased turbulence in tubular scenarios, even when factoring in flow resistance.

Thanks!

Summary of results
 

Waterflow => ~7lpm

Tricod @ 5.0v => 0.075 c/w
Tricod @ 12.0v => 0.044 c/w
Panaflo L1A @ 12.0v => 0.031 c/w
Panaflo H1A @ 12.0v => 0.022 c/w
Panaflo H1A @ 16.0v => 0.020 c/w

Tricod is a Yate-Loon rebadge
Panaflo H1A @ 16.0v was chosen to approximate a Delta AFB1212VHE fannage level

Can I quote those figures on the PA160 page over at ThermoChill d00d?

Sure.

'twould be best to accompany them with a link to the original thread over at OCAU of course, just so people can check the source.

See the PA160 page (and scroll down it).... I updated it the other day with links to relevant threads here and at OCAU so that's more or less done already... but yep! no sweat!

EDIT: heh, my impatience *tsk* too late to ctrl-z too!

I think that adding the noise/cfm levels per fan would be useful.

Tricod @ 5.0v => (est.) 10dBA / (est.) 23cfm (I actually think the noise level would be less than that - but I doubt that people would swallow such a figure as it is an estimate)
Tricod @ 12.0v => 22dBA / 45 cfm
Panaflo L1A @ 12.0v => 30dBA / 69 cfm
Panaflo H1A @ 12.0v => 41dBA / 104cfm
Panaflo H1A @ 16.0v => (est.) 48dBA / (est.) 130cfm

Disclaimer huh? Procedure and some statements of the levels of error are given in the origin thread. I would say just give the above figures and point to the thread for more info - and people can read about what was done and make the assessment themselves if they so choose. Heck - that sort of transparency is already infinitely better than what most manufacturers provide. It's not a professionally done test, I openly admit that, just as I do a number of times in the origin thread.

Maybe a disclaimer that says "* - preliminary results - see thread here for further details"

Doneskis...

Thanks again for the 5V test, Cathar. The low airflow performance is most impressive.

However, your noise estimates look a bit optimistic. YL rates the low-speed D12s at 24 & 28 dBA, depending on bearing. The sleeve bearing is the louder, which seems odd; perhaps they swapped things. In addition, MikeC at SPCR measured the Nexus at 22-23, and that's a 25% slower fan.

Yate-Loon site appears to be down, and I never have been able to access it. Don't know why.

Tricod information is non-existent everywhere. Fan noise levels are not standardised anyway.

The Tricod fans that I have here are the sleeve bearing fans. I have 4 of them just sitting here, and 4 things at once is a 6dBA increase over a single thing. Running all 4 at once next to the Panaflo L1A manufacturer-stated 30dBA results in the Panaflo still being clearly louder than the 4xTricods.

I don't know - am more making comparisons relative to the base-line of the L1A at 30dBA, which to me is quieter than any other so-called 30dBA fan I've held.

If the Panaflo L1A is 30dBA, and the sleeve bearing Yate-Loon's are 28dBA (thereby making 2 x 28dBA items = 31dBA), then I'll gladly admit to being deafer than a doorknob if 2 x these Tricods are anything as loud as the Panaflo L1A.

Maybe I should invest in a sound-meter, but then, what would that accomplish without a common frame of reference for everyone else to calibrate to?

Stew you are not deafer than a doorknob, but I am :D

LOL - wasn't going to say anything but yeah. After you swearing black'n'blue about how quiet "The Beast Mk. II" was, and I walked in and practically had to shout to make myself heard....

Yeah but even with all fans OFF, it is loud, it's the PSU :dome:

Yep... PCP&C = noisy beast - open it up, disconect it's fan from the mainboard and hook it up to a fanbus, or swap it out for a Panaflo 80mm... I had the same issue :)

Anyways.... Tricod. A part of the CodeGen Group. Found in CodeGen cases (also sometimes named as TriCod cases) and Codegen PSUs. I get the feeling that the TriCod 120mm fans are harvested from Codegen 350w & 400w PSUs - the cheap and nasty ones that in the UK only feature 80mm fans, but elsewhere in the world can be found with 120mm fans; and that are often found fitted in cheaper cases. In many cases for system builds these PSUs are insufficient, whipped out, useful parts stripped, then binned. I suspect your supplier does this regularly.

Anyways, the Tricod homepage is down due to a futzed odbc driver, but delve past index.asp and you can get in and get contact details (altho minimal) and hopefully they can get in touch and provide you with some details... particularly of interest, whether the fans are available individually to retail, or whether they can only be found in their PSUs / Cases.

Tricod.de DOES resolve but again doesn't give any info on the fans as products in their own right, but does show the PSUs that they're harvested from...

Hope that's of use to you d00d!

BTW, Cathar - One of the fans I'm sending you, the Xinruilian 0.18A 120mm fan...

Here's some details for it.

Rated Voltage: 12vdc
Startup voltage: 6vdc
Current: 0.18a
Speed: 1700 rpm
CFM: 72.1
Static Pressure: 2.0 mmH20
dBA: 27.2

The above fan is the "L" labelled curve.

S'the RDL1225S as shown here: http://www.xinruilian.com/doe/dc/1225-l.htm

They make a lot of fan and blower products.... check out their site root in IE (navigation doesn't work in Firefox)
