Got something in my mailbox today, and upon bringing it inside and opening it...



Ahh, but I tease. Here's the money shot.



キタ━━━━━━(゚∀゚)━━━━━━!!!!! (Kita!!!!!; It's here!!!!!)

As I said, I'll soon pit this deity of airflow against the Panaflo U1BX, which I've been using since I upgraded my system. This thing is slightly heavier and more solid than my Panaflo, and amusingly came in a box meant for a Swiftech MCP-655. The Royal Mail and US customs treated the package very well; if requested I'll upload the pics I took of the packaging.

Spinning the blades with my fingers, I can tell you this much; if you run it at full speed and stick your finger in, your finger will break before the blades. Also during my little twiddly-spinning (lol), I noticed that there's a nice little push of air. If only I had an anemometer, I could say what the CFM is at... however many volts runs along the nerve endings in your fingers.
I won't bother reserving a post, I'll simply make another post with my temp comparisons during a small FFT Prime95 run, and link to that post in this one.

UPDATE: Results and testing conditions here. Panaflo wins, but I can't seem to figure out why for the time being. The San Ace undervolts better, it sounds better across all voltages, and it'll last a very long time. If I had to say, I'd still prefer the San Ace because, well, it's a San Ace! These fans are legends of air and water cooling alike, and I'll always recommend them if I see they're still available (and they still are at the time of this update). If they are unavailable, though, I'll recommend the U1BX hands-down. Why not the H1BX, which I also have? Well, because I have both models, I CAN say why; the U1BX is QUIETER at all voltages. I cannot explain this, either, nor do I have reason to.


Anyway, that's that. In short, this thing's a keeper, though I will need to find its predecessor and compare it to that to give you the full story.

Disappointment is in the air. The fan is not starting. Cabling and power were double-checked, everything is connected as it should be, I even checked the Rheobus itself and that's not the problem. Any ideas? I'm going to power off and reconnect the San Ace to a molex connection and see if it'll start.

check the 3 pin connection and see if it was wired on correctly

Update! It does work on direct molex, and it's quite loud. The tone of the fan is pleasant but it fills the whole damn room. I really can't figure this one out right now, I'll check the 3-pin extension.

lol i know why it is a 24volt thing if you dind't know mostly those fan controller are 6-12volt so it won't work

no, it's 12v .38 amps.

CC, check the 3pin connector. One of the wires may be lose or about to break.

Wrong, the second "12" in the model name indicates it's a 12 volt fan.

I have it working on the controller now, I just had a lapse of sanity when running the extensions is all.

EDIT: I have noticed a very high-pitched squealing sound that lasts for about 3 seconds when the fan first starts. It's inaudible unless you're a foot or closer from the fan. I have estimated its starting voltage to be between 4 and 4.5 volts. I will say though, that at full speed, even though only 100 RPM separates it from the Panaflo U1BX, it sounds MUCH smoother. I now know what Vapor was talking about in his roundups that included the 109R, the predecessor. It's great.

Beginning Prime run! Will post temps here. Previously with the U1BX, these are what my results were at 7 volts and 12 volts respectively:





2nd edit; still running Prime, as of now 14k length tests are starting. Temps have leveled off, these are the current numbers at 7 volts, and I gotta say, this is a bit peculiar:



Complete. 12v temps:



I can't explain what's going on, really, but I noticed a healthy 1-2 degree drop when I increased the Panaflo (which is now rear exhaust) from 7v to 9.5v, making this cooler quite suitable for push-pull setups. OP updated with a summary.

Also RawZ, I don't know if you saw it the last time I posted, but I gotta note again that you're going to kill that top exhaust fan with that much static pressure being directed right at it. Don't be surprised if that exhaust stops working soon.

Loooooong needed edit; Anyone looking at these results probably want to know the testing conditions, so: Sunbeam Rheobus (non-Extreme), stock-clocked Core i7 920, Blood Rage (original, unmodded), 72*F room temp for BOTH tests (verified and monitored by wall thermostat near this monitor, controlled/balanced by a gas fireplace if below 72*F, large fan near the window if above 72*F). Other specs have remained mostly the same from this testing to this edit.

Hey, you got your San Ace I see. I'm still waiting for mine. So you got all disappointment?

Not at all. Read the updated portion of the OP.

Read about that. So what was the reason when initially you can't run it on your fan controller?

And did the squeak go away already?

Why would the Panaflo U1BX be better than this fan?

I don't know why the Panaflo yielded better results, especially when my exhaust at the time was a low-pressure Cooler Master fan. But I can tell you that the San Ace undervolts much better and has a significantly lower starting voltage (4-4.5 volts compared to 6 volts), so overall, when you neglect the posted temps, the San Ace is better.

The squeak goes away once the motor completely starts. Like I said, it only lasts a few seconds.

I couldn't get it working at first because, like I said, I'd had a lapse of sanity running the fan extensions (and in the process embarrassingly sliced my leg on the male end of one of the extensions I'd disconnected).

Ok


So the difference in performance is 1-2C right?

Do other people experience the same results with these fans?

Yeah.

Couldn't tell you. It depends on the fans they're already using.

Will 2 San Ace 38mm fans working at lower speeds match up to 1 San ace at 2600rpm for Megahalems? I am asking this because 39dba is loud.

there's was a comparison made here @ OCN by someone that showed two San Aces spinning @ different speeds. I think the results were that spining @ a lower speed yielded a better result or something. I forgot where's the link to it, hope someone can post that.

So two San Aces spninning at lower speed will be better or match up to 1 san ace at full speed? Thats mean lower noise so i will buy two san aces in that case.
