Yate loon SL or Scythe Kaze slipstream?

[kiparosu]

I'll be putting 2 mcr 320 in a staker tot cool a q6600, 8800gts and the nb.
My question is what fans are best for this setup? 3 yates SL orange/black or 3 scythe kaze's slipstream 1200rpm?
I'll be using a fan controller and I want silence, but still would like some good cfm for summer benching...

go for Petra's Yate Loon D120SM or SH (medium or high) and undervolt them. you never know when you might need the extra cfms...

[kiparosu]

What about jab-tech's yate loons?

[MINIz guy]

I just bought a set of Jab-Tech's D12SH-12 and they are very quiet when undervolted. I didn't notice any weird sounds yet, and it does blow a lot of air quietly enough.

I just used 2 of these, as my radiator is a MCR220. I could stand 3 of them blowing at full blast, as I am used to my vacuum cleaner type Thermaltake fan and noisy not to be named PSU.

[evoted]

i dont think it matters where you get them, as long as you get the YL....i got theses http://www.petrastechshop.com/12yalod1cafa1.html not too long ago, but JT are cheaper....and i dont think they are too loud...

[Giannis86]

it does matter actually as PTS offers special curved yates which are more effective on rads..check vapor's sticky on fan testing

[kiparosu]

yeah, I read that thread. But I'm wondering about HS yates differences beetween petra and jab-tech.

[MpG]

At this point, it's definitely been documented that there are different YL's in circulation. There's plenty of anecdotal evidence, although if you haven't seen this thread (http://www.xtremesystems.org/forums/showpost.php?p=2641609&postcount=6) by Vapor, it sum things up quite nicely.

At this time, I don't believe Jab-tech has been confirmed as selling the better YL's. I've got some vanilla YL myself, and while they're certainly not bad, they fall short of fans like the Noctua P fans and the Scythe S-Flexs'.

[kiparosu]

Thanks MpG. That cleared things up :) Do Petra's HS loons make any weird noises undervolted?

second that!

how did all that get started in the 1st place i wonder...as far as testing diff between fans from diff vendors...

[Martinm210]

I've been using petra curves yate loons and undervolting them for my radiator testing, they work awesome all the way down to 1000RPM and even lower if you need to.

I also found that Petra curved D12SM12s at 1350RPM were about equal to the straight blade D12SL12s in my PA testing.

I'm not sure how Petras gets the curved ones, but they are superior. If you're going to use a fan controller, I would opt for the mediums then you have some flexibility. Also Vapor's testing seemed to indicate the mediums do a little better.

I do one of the scythe slipstreams as well, but I havn't done any testing yet. They seem like a nice fan, but I'm thinking the fan blade pitch is more flow oriented than pressure.

When I get down to my RS120 raditor testing, I'll do some thermal comparisons with a few fans.

[kiparosu]

Yes, I'll go for Petra's medium loons+ sunbeam controller. Are the medium yates at 5v silent? Any rotor noise or something? I'll be having 7 in the case

If someone can point out a quieter fan, I'd be suprised, but I'm not a ultra silent fan users, I'm happy with them at the 1350RPM range.

I think the medium speed take around 5.9V to hold at 1000RPM, so 5V would be even slower than that. I guess some people run them down to 800RPM, but I consider 1000 ultra slow speed and dead silent. Fan performance really drops off at that point too though.

[kiparosu]

Also one mcr320 is going on the bottom of the case, so the fans will be pulling horizontaly. They are going to crap out sooner in this position right?

That's what Cathar said a long time ago, but I'm not sure it's something to worry about too much.

I guess the idea is the bear gets more lateral pressure and possibly the bearing lubrication works it's way out. Alot of people run them that way, so I wouldn't worry too much about it.

Nice thing about the cost if they do give up though.:up:

[kiparosu]

For sure. I'm getting 3 extra just in case :D. Thanks alot for you input Martin!

i was told that YL mediums are great with the PA120.2 or .3

[kiparosu]

2xmcr320=100$
pa 120.2+120.3=235$

I'll stick with 2 mcr320 for q6600+vmoded 8800gts 512 and nb :D

If you want to use low/medium speed fans, go for Thermochill radiators. Otherwise, go for Swiftech radiators.

[kiparosu]

Well a mcr320 matches a PA 120.2 WITH shroud on low/med cfm fans.
So I figure I get 2 shrouded PA 120.2 for half the price. 2extra fans at 1000rpm I think are hard to tell if they are there or not and I can always crank up the voltage on the fans for some hot summer benching :D

Credit goes to Testing Performed by Radical_53 - Germany for the radiator data.

2 mcr320 will do just fine for 500w of heat that I'm dumping in.

[aspire.comptech]

The rule is Thermochill/Swiftech for low/med spd fans and BIP/BIX/Stealth GT for high cfm fans.

The results of that testing are inaccurate (or so I've been told).

Oh, I've always thought Swiftech just is like one of those BIP/BIX/Stealth GT radiators. According to the site of Swiftech, you are correct. :up:

[Pedalmonkey]

the Swiftech have a lower fin density like the thermochill. however b/c they arent as thick the surface area of the fins is reduced.

i think it is something to worry about. i bought 3 med speed YL from frozencpu about a year ago, they have been running horizontal since day one.
the fans have become much louder (the motor noise). i also can notice the blades "wobbling" much more than they used to. and im not so sure that they are putting out as much cfm as they used to...

i dont want anyone flaming me on this, im just saying things that i have seemed to notice. i dont know if this is 100% but these all seem true due to my experience.

[septim]

ripken thats normal, its termed the sleeve bearing grind of horizontally mounted sleeved bearing fans like the yates and slipstreams or kazes... all sleeve bearings.

if you want a good investment though you might want to grab some sflex-e/f/g,
personally i would recommend the F and undervolt it. the ones i am using are close to 2 years still quietly blowing...

[MpG]

I've heard that a few times myself regarding that particular set of data, although I'd dearly love to get the whole picture behind. But what it's worth, those results don't even jive with Thermochill's own graphs.

ya ive only heard assumptions on the sleeve bearing fans.
i want to get a TJ07 soon, then i can have my fans vertically mounted on the rad in the bottom chamber :)

Good to know:up:

All of my fans are run vertically in my system, so I don't have any experience with long term horizontally mounted issues. I do run them horizontal for my radiator test bench, but that's about the extent of it.

There is obviously lateral pressure on the bearing from the fan blade pulling, so perhaps is the lubricant issue.:shrug:

[MomijiTMO]

I would love to hear other opinions on the orientation of the fans.

[ripken204]

ya the lubricant issue is what people have been assuming. my fans are definitely ALOT louder now than they were a year ago.
i have a great ear so i can hear details like that.
it would just be nice if someone knew details about these fans.
too bad i cant just flip the fans around, kind of like rotating the tires on a car in a way.

[MomijiTMO]

Hmmm I guess running them vertical is the way to go. I'm going to have to change my plan :)

[ripken204]

lol, now im going to have 100 ppl freaking out and changing their setup thanks to my posts.
at least we can get a whole bunch of new worklogs :)

[iandh]

I've toasted so many sleeve bearing fans running horizontal that I won't use them anymore, which sucks because I love the Yates. Most of mine would last about 3-4 months, even with lubrication. They would start to make an almost grinding sound, that may or may not be apparent to everyone.

Right now I am using some of the Lian-Li branded Adda ball bearing fans, and honestly they are just as quiet as any fan I've heard at 800rpm. They are even pretty reasonable at 1000rpm, but after that they start to fall behind fans like the Yates that sport superior blade designs. Luckily 800rpm seems to do Ok for my cooling needs. I've had seven total running for a couple months now, four vertical, and three horizontal on the rad, and they all still sound identical. Gotta love ball bearing fans.

[septim]

iandh were'd you get them adda fans. i suggested to vapor to test them out, i have some that are still pretty quiet with decent airflow and i would acquire some more if they were cheap less than $15 each like an Sflex...

[iandh]

Three came with my rocketfish, two I had before from another Lian-Li case, and I bought the last two from ebay for about $8-9 each shipped. PM me about a forum member who has a lot of 5 for sale for $20. :)

[kiparosu]

So if I get 3 Sflexes I pay 40$. Maybe I'm better off getting 10Medium loons and changing them every year :))

[BlazinTiger]

question, what bearings do yl's use?

[MpG]

Sleeve bearings.

[BlazinTiger]

then can u still use em horizontally?

[MpG]

You can put them in any orientation you wish. However it's the combination of horizontal mounting + sleeve bearing that creates the possibility of premature failure. You take your chances, that's all.

[BlazinTiger]

oh ok, so it has a possibility...anyone know how often? sry for the q's

[MomijiTMO]

The fan's lifespan will be reduced. No one can predict when they will fail but if you replace them once a year and don't mind the increased noise, mount them horizontally. As you would have noticed, a lot of members still have their rads mounted in this fashion and are not perturbed by possibility of fans dying prematurely.

I have now decided to mount my rads vertically after reading more information on this topic. :up:

[BlazinTiger]

i think this is on topic...so noise levels of YL's vs. Scythe slipstream vs. maybe s-flex?

[MomijiTMO]

The manufacturers have the dBa listed on the sites :). I believe the slipstreams are the quietest of the trio but the s-flex is the best performer. Grab the Loons for the best price/performance ratio.

[BlazinTiger]

i proposed the s-flex cuz i was thinking of a top mounted fan on a case

[septim]

the sflex would last longer...
