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

^^^^^

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. :+1: . 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. :+1:

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

I have a close up picture in the OP. I could make it bigger and ad one straight on.

Cool,we can ALL have names for our Opus’s! :+1:

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?

Interesting stuff :+1:

OK, thank you. I see you posted pics while I was typing. :slight_smile:

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.

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. :sunglasses:

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.

This is in regards to the “NEWLY PLANNED GENERATION” OPUS which is due out in several months. This will be his present to me!

to me
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

I have asked him everything that I have needed to ask him. Now I wait to hear from him in several months when the charger comes out.

Sounds like a good plan to stop before stripping… it looks good. :slight_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… :+1:
Interesting & sounds good…. like they are trying to get it right on the first try.
Dropping termination to 2.7 V also…… works for me. :slight_smile:

Thanks again for posting this info Robert. :+1:
