Panaflo or Yate Loon? - Page 3 - Overclock.net

honestly, are the yates even worth it over the s-flex? I know the s-flex are more expensive but I have never heard of this QC problem with them by where you get them from.

Yes, well worth it from my experience. If you're looking for high CFM only, the S-Flex's are fine, but are much louder than reported...much.
Again another case where I'd say if you were using a controller fine, but otherwise no.

Actually my S-Flex G is somewhat tolerable at full speed. It doesn't sound as nice as my U1BX or especially the San Ace, but below 9 volts it's great.

Yate Loon.

I have the Pan 38mm Ultra and the noise it emmits when undervolted is unbearable. Almost sounds like a mini propeller engine.

To answer the OP's question, a Yate will be fine for that application no matter where you get it from, though since you won't be buying for a few weeks, go ahead and get them from Petras when they're in stock. They should sound better.

What you linked is so terrible. He provided no source for his graphs other than numbers. He didn't provide testing methods, nor did he provide all of his circumstances.

Oh please. Did you look at the first round up linked to in that topic? He lists the test methods in the first post. If you don't want to go there and look for it, here:

3) To measure CFM, I purchased an anemometer that could accurately measure the 120mm equivalent of ~2CFM all the way up to ~350CFM. Rather than just put the anemometer up to the fan and draw a conclusion based on air moved at the hub (which is almost useless), I have shrouded the entire area between the anemometer and the fan. This is to ensure that all airflow is measured, not just the airflow at the hub or another part of the fan. On top of that, because air coming out of a fan, in addition to having forward momentum, has rotational momentum, I have the fan pull air through the measurement setup. Initial results, compared to trusted ratings (Delta, Panaflo, Yate Loon) were EXTREMELY accurate. CFM testing was done at 1V increments between 4V and 12V when possible. Minimum running voltage was also tested. This test is to test the validity of manufacturer ratings and also CFM pushing capabilities as a case fan.

To measure the restricted CFM, I fastened a Swiftech MCR120 radiator between the fan and the measurement setup. This would put a consistent restriction on the fans, and because it was also a commonly used radiator, it allows us to draw conclusions which fans are best for a typical radiator setup for watercoolers, especially those using a shroud to reduce effects of the hub. Restricted CFM was tested at 1V increments between 4V and 12V when possible. Minimum running voltage results were extrapolated from 4V results.

To measure decibel ratings, I fastened the fan on an exhaust hole on a case and positioned my decibel meter 12cm away from center of the fan. It was angled from the side such that it would not suffer from any buffeting. The dB meter is isolated from any external vibration through bubble wrap. dB readings are used throughout the comparison and are measured from 4V to 12V, as well as minimum running voltage.

To measure CPU tempurature, I used Thermaltake Big Typhoon VX on a Celeron D and P5W DH configuration clocked at 3.6GHz and 1.63V (loaded). This setup was used because the TTBT can easily mount ANY 120mm fan, responds well to increased airflow, and because it is a very good cooler also capable of keeping the Celeron stable with very low airflow. The Celeron D was used because it runs extremely hot yet can also run at extremely high temperatures stably (87C loaded was the highest temperature I saw, and it was stable). Speedfan and OCCT were used to load, measure and record temperatures. A UEI DT200 was used to measure ambient tempuratures. WCG was run as an 'idle state' in order to prevent the processor from cooling down too much, allowing me to use a shorter (8 minutes rather than 30) load time to assess performance. If a processor did NOT cool down at the completion of the 8 minutes of load, the test was repeated until it did (always the next try). The maximum temperature readout was used as loaded temp. Ambient temperature was subtracted and gives use a dT, the basis for determining which fan is ideal for CPU cooling. This test was done because restricted CFM alone cannot be used to determine fan performance cooling a CPU due to varying hub sizes and air dispersion patterns. The test was performed at 12V, 9V, 7V and 5V when possible on every fan.

You really think one of their own admins wouldn't disclose this? Give them SOME credit.

The point is that you provided a link showing a graph with no source. I didn't discredit them. I discredited you. You should know better than to post "proof" without technically providing a source.

I know your not new but your probably new to the Air Cooling section. Vapor at xtremesystems is pretty well known as a respectable tester of fans. We can't go linking 15 threads of his to show he is credible every time we want to link information that is pertinent to the current thread

Really though...I see his reviews/research of fans linked in about every 15 threads here.

Again, I wasn't discrediting Vapor. I understand that you can't link "15 thread", just only the thread pertaining to the issue. Which needs maybe 3 links at the most.

As I see it you're at fault for not investigating yourself. The link was easily accessible from the topic in my own link but you didn't seem to bother looking at it. Either way, the point's made, there IS a difference between higher-quality Yates and the cheaper ones. The irony of this is Petras' Yates are less expensive than Jab-Tech's, CrazyPC's, Sidewinder's, and PPCs' Yates. Note that if you're in Europe, or you just want another option, Aquatuning carries Yates that are ordered directly from Yate Loon, as well. Be aware that importing from outside Europe is VERY expensive; in my case getting a D12SH-12 from AT would be ~58 dollars in shipping. FOR ONE FAN. But there is comfort in knowing that if you don't mind burning money like firewood, they WILL ship to you (and they calculate rates based on weight). If you're in Europe, Aquatuning has been expanding their shipping options to more local rates and times so it's not nearly as much if you're living over there.
