OPUS BT-C3100-Stock Fan VS. Top Tier Delta fan

First I want to thank speaker_joe for donating the Delta fans, Dale[DB Custom] for splicing the Delta fans with the proper plug and donating his skill and time. Also HKJ who spent several hours with me Three weeks ago in determining whether the Opus Transistor was capable of handling the wattage of the Delta fan.Without their help and input this thread would NOT exist.

One of problems I was having with a few Opus chargers is during discharge cycle w/ 4 X 18650 3400mAh batteries, the charger would have too many stoppages which was one of the causes that gave inaccurate capacity results. The batteries just could not stay cool enough and when that happens the charger automatically stops until they get below 40C/104F.

I know this[STOPPAGES] is mentioned in the manual. I also believe they are a DIRECT result of the inaccuracies of the capacity[mAh] readings. This simple test seems to Verify that.There was no doubt in my mind that a better quality fan would remedy this problem.

This test is with the EXACT same charger using the stock fan VS. my Top Tier Delta fan.Also the EXACT same batteries. That alone makes it pretty easy to come to a conclusion of which fan is better and how each fan affects the Capacity results.

I am testing Three sets of 18650 batteries that were tested within a week of each other,,some the same day.

The batteries are: 4 X 30Q BT,4 X KP 18650 3400mAh and 4 X Orbtronic 18650 3400mAh. I have NO plans of using the old fan so these are the only comparison tests that I have.

For the Stock fan tests of the ORBTRONIC and KeepPower I only have written stats.

ALL TESTS ARE DISCHARGED AT 1 Amp.

Specs. for fans: DELTA: 25mm X 25mm X 10mm——————-ADDA:25mm X 25mm X 09mm. The only difference is 1mm in depth.

Stock[ADDA] fan- 5v/0.13a/0.65W

Delta fan- 12V/0.12A/1.44W

Picture I took of the Transistor[1AMH]behind the fan plug that helped HKJ determine if the OPUS was able to handle the wattage of the Delta fan[1.44W]

To my happiness, HKJ Confirmed the Delta fan was safe to use!

HKJ: “It can handle a bit above 2W at 12V”.———————— My Delta is 1.44W at 12V Thumbs Up

The DELTA fan has more depth, no grooves to fit in slot and when the cover is tightened the top protrudes slightly,,,no biggie,,works like a charm!

All Three of the tests using my Delta fan are closer to specs. than the STOCK fan. For the Keeppower and Orbtronic the age/cycle count must be considered to determine the accuracy of the tests.

The STOCK fan gave higher numbers for ALL Three tests.If you look at the Discharge times, the STOCK[Adda] fan took Longer in all Three tests and its mAh numbers were higher and further away from specs. There seems to be a correlation with that.

I enjoyed doing these simple yet helpful tests. I hope someone else may find this to be of benefit to them.

I am VERY happy with the Delta fans and now its time to celebrate my 57th Birthday w/ friends and family. Party

^^^

Thanks for the input

Yes,,,,It certainly indicates that.

I thought of this last night when I was walking CAPO.

The 30Q’s are basically new and it is pretty clear to see how much closer to HKJ the “Delta” fan[median of 2890mAh] is compared to stock[median of 3009mAh].HKJ’S reading is 2884mAh.

The Orbtronic and KeepPower are older batteries so it makes it a little harder to prove it. However, by looking at the numbers it certainly appears that the Stock fans numbers would be higher and more inaccurate in comparison to HKJ’s test.

KP.

Stock fan = 3208mAh
Delta fan=3087mAh
HKJ=3211mAh

Almost 2.5 years old and 170 cycles it is very, very unlikely its capacity at that point would be 3208mAh[Stock] which is only 3mAh below HKJ’S numbers.

The Deltas 3087mAh certainly seems more realistic.

Orbtronic:

Stock=3012mAh
Delta=2870mAh
HKJ=3162mAh w/ the panny “B” cell. Same cell in Orbtronic.

Again, with a batteries 4.5 years old and 465 cycles you would think that the Delta’s numbers are more realistic.

I think it would be very, very unlikely that only 150mAh capacity[Stock fans numbers] was lost over that time period with that much use.

To me this is NOT rocket science although some insist to treat it as such. To me it is fun and I see better results w/ my Delta fan and that is all that matters. Wink

If people were more like Dogs the world would be a better place. There would be much less conflict and violence,instead there would be true harmony and grace.

A few other things.

When I first plugged in the Delta fan I knew it was going to work much better. Two of my senses told me that.

Hearing- The sound was a bit louder,,more RPM’S and its ability to move air[CFM]

Touch-I could feel such a difference in the air that was being expelled by the fan [CFM]. Much, much improved over stock fan.

There has been some discrepancy and confusion about the dimensions of the Opus stock fan. Primarily the depth/height.

My friend is a mechanic and is going to let me use his micrometer,,if he can find it. The one at work is only used for measuring rotors and would not be big enough.

Henry Xu is baffled how I got the Delta fan in!

Here are the specs. of my DELTA FAN
Specification
Nominal voltage : 12 V
Current : 0.12 A
Operating voltage range : 4 – 12 V
Fan speed : 13,000 RPM
Performance : 2.4 CFM
Noise : 28 dBa
Size : 25 × 25 × 10 mm without heatsink

Until the dimensions are verified I can not confirm the specs/diameter of the Opus Stock fan[Adda].

If people were more like Dogs the world would be a better place. There would be much less conflict and violence,instead there would be true harmony and grace.

Good job wolfdog (and kudos to speaker_joe for taking my suggestion to send the Delta fans your way).

What impact do these results have on your CPF test results for your original Opus? Recall some of those were up to 15% higher than HKJs results. Did it have the original fan? Was it pausing? How would the Delta fans have affected the results? Would the original be better or worse with the Delta? (I don’t recall the details).

Btw, to folks who bought the Lite-On SMPS from speaker_joe: please don’t forget to leave feedback. eBay sellers live or die based on feedback.

^^^^^

 

What impact do these results have on your CPF test results for your original Opus? I do not know. I can ONLY compare Apples to Apples which is what this test was.

 

The PRINCE[new name for my present OPUS] definitely has more accurate readings than the First Opus. In fact, The PRINCE was slightly better than KING OPUS on One of the Three tests I did on this thread. The other Two They are basically equal. It is hard to tell because they are older batteries and you can not use the NEW battery specs. to tell which one is closer.

 

Recall some of those were up to 15% higher than HKJs results. Did it have the original fan? Yes

 

Was it pausing? I am NOT 100% sure. I did not watch the first OPUS one as much. 

 

 How would the Delta fans have affected the results? I would think the results would be better

 

Would the original be better or worse with the Delta? (I don’t recall the details).No way to tell. The original is gone. I would say the results would be more accurate to specs/HKJ.

good choice.
i have seen so many adda fans bad in stuff that we call them “death adda”
only downside to a fan that moves more air is a bit more noise.
i had a fan cooled charger that still ran too hot.
the traces were too small to serve as an effective heatsink.
so i soldered short lengths of copper tubing over them.right to the drain tabs.
might be another trick to do to these chargers.

Thanks,,,,,,I had some people along the way make the Delta fan come to fruition!

Us Flashaholics are a little different! I actually enjoy listening to the power of that fan! It is like a hair dryer on low! Yet it is not much louder than the stock fan.

Between the Lite-on SMPS, its accessories and the Delta fan[Shipping to and fro and extra fans for the plug], my Opus is worth about $75/$80! The fan was donated and so was Dales work. A lot of generous people.

I hope Dale is feeling better, he got a serious neck operation on June 1st.

i will wait untill my opus fan died out so i can replace it with this delta fan

ok,,,,why wait?! lol!

I guess if your fan is doing the job and your satisfied you may as well wait.

I am not sure where you live? S.E.A.? South East Asia? South East Alabama?!

Here are Two Ebay links when you want one.

First is speaker_joe in USA who gave me my fan.

Then an Ebay dealer in China:

My good buddy Jon who is Owner of Liionwholesale was kept abreast of my “Delta Destroyer Transplant Project”!He was very impressed with the results. He asked me where I got the fans and I directed him to speaker_joes Ebay link.He ordered Six for his in house chargers. I would think he will find improvement although he still has the STOCK Power Supplies.

On a side note. I have been corresponding with Henry Xu from Opus for about 3 weeks or so. Wednesday or Thursday I will post some pertinent information regarding the “Newly Designed Opus” that is due out in several months.

Good info Wolfdog & congrats on the sucessful fan transplant. Thumbs Up . Any chance we could get a few close up shots of it in the charger?
You have stuck with this & seen it thru… congrats.
Looking forward to that info on the new OPUS they are coming out with in the future too. Thumbs Up

I am fortunate the LiteOn Power supply seems to have solved the problem I was having. Smile

But following your lead, I have named my OPUS also. I have dubbed it with the title of…… Budro Tibido “Boo-Yah” OPUS.

For short, I shall refer to him as Boo-Yah; cause after the new power supply he is young & tough again. Wink

Much like the little dude below…..

Wolfdog—- Glad to see you are all fixed up—I know you were struggling with the fails,resets,etc—- The fan looks great from what I can see
Not to be left out—- Since I’ve never had none of these problems with my 3400 and it seems very close with it’s results—I decided to give him a name also- Being from the South I think Robert E Opus is a fitting name—- Jurys still out on the 3100

This is the best possible picture in my opinion.I enlarged as much as I could[100%].The OP version was 85% iirc.

It is clear and you get to see how much it protrudes. Not really that much in real life.

Picture from front.

Notice the label is side ways? I did that on purpose because the wires lay better and are on the center of the board[not getting pinched] at 7 O’clock VS at 4:30! Wink

The cover was pinching the wires a bit when installed at 4:30.

Right, I’ve seen that one. I was just hoping for a different angle close up. It looks real good from what I can see too. The slight gap in the case probably helps in air flow to wouldn’t you think?

yaaa, the little gap can not hurt,,,a little extra ventilation is good

The reason there is a gap is because I did not want to strip the screws like I did w/ King Opus! Also,It is not a perfect fit so once it starting getting tight enough I stopped tightening.

EDIT: The screws were not stripped. The fiberglass board[holes] got stripped.

Interesting stuff Thumbs Up

Thanks,It is exciting to be a Flashaholic when through a learning process and help from others, we get to see results derived from manufacturers imperfections. Cool

Henry Xu is very accommodating and pretty efficient and reliable.

to me
Hi, Robert

With our new design, we have not fixed the fan size yet. If we can use two bearing type fan, I think the problem of fan reliability issue will be fixed, no matter ADDA fan or some other fan to be used.

We are still reviewing the fan internally.

regards

henry

Hi, Robert.

For discharge terminate, we will terminate at 2.7v with load of 1000mA. With this conidtion, it will be safe for batteries with protection.

regards

henry

yaaa, the little gap can not hurt,,,a little extra ventilation is good

The reason there is a gap is because I did not want to strip the screws like I did w/ King Opus! Also,It is not a perfect fit so once it starting getting tight enough I stopped tightening.

Sounds like a good plan to stop before stripping… it looks good. Smile

Henry Xu needs to make readily available replacement parts (Fans) that work in his products—That would be a good start for us past customers

OH… I just saw the info from Mr. Xu you posted. Thanks for posting it… Thumbs Up
Interesting & sounds good…. like they are trying to get it right on the first try. (hopefully)
Dropping termination to 2.7 V also…… works for me. Smile

Thanks again for posting this info Robert. Thumbs Up

yaa,,he needs to upgrade the fan which he appears to be doing and also provide easily accessible replacements.

For me, I would not use his stock fans in mine anymore unless the newly designed one coming out has ZERO STOPPAGES during discharge. Even then I would probably put the Delta in. I love the results and actually listening to its impressive CFM!

I have 2 X Delta fans and I have a source[speaker_joe] to get more.

Opus would never put that high quality of a fan in because of costs.

For people curious like myself.

The reason the TOP of the fan protrudes more than the bottom[which is actually flush] is because when tightening the cover plate it pushes on the bottom of the fan and with no grooves to keep it in place, the top pushes out and protrudes.If the fan had grooves it would still stick out with the additional 1.5mm in depth. It would just be an even protrusion! lol!

5V DC??
Have you checked what voltage is applied to the fan?

^^^^

The fan has a resistor to cover the other 7V.

I do not recall how “rdana” and HKJ explained it,,,,but it works.

EDIT: Here is “rdana’s” answer. He is the ONLY one who sells the BT-C3400 V3.1

The original fan has an inline resistor added to it, this is why the fan is 5v, the terminal on the pcb is probably providing unregulated 12v (obviously the external PSU is regulated). The 5v fans is a probably the cheapest they could find and they just added a resistor to divide the voltage, I would think the gearbest fan is better at least in that regard. Do not use a 5V fan directly on that board, it will almost certainly blow out or die within days.

The ADDA fan w/ resistor is on the left.
