Opus BT C3100 Erratic Behavior - Fan Gone???

wolfdog1226 · 2019-03-21T20:25:11.000Z

A look with my DELTA fan installed. It is slightly bigger[1mm] in Depth so it protrudes a bit.No issues, been working like a mule for 2 years!

Set up w/ my Lite-On SMPS

I’ve got a BT3400 v. 2.2 and its OEM fan has been quiet, but I bought two of the Delta fans off of Ebay just to have as spares, as Wolf has suggested.

I also bought the LiteOn 5.5A 12v power brick and while I don’t use it regularly, it was fairly cheap to get ($12 shipped?) My inner hole on the barrel connector is slightly over sized, so if I jiggle it when the charger is running, it’ll disconnect, but I just don’t move the charger once things are charging.

The barrel connectors are slightly different. I got adapters for a few dollars and they are snug.

I like the 90 degree one. That is the one I have been using since spring of 2017 when I made fan/SMPS changes. :+1:

Thanks for the advice, as always. Do you recall the specific size(s)?

Thanks, Chris

VERY IMPORTANT NOT TO REVERSE THESE NUMBERS.

It needs to be 5.5mm X 2.5mm MALE TO 5.5mm X 2.1mm FEMALE

here is thread where we talk about the adapters and show a few pics.

Difference between Opus BT-C3400 & BT-C3100 v2.1? Chargers

This may have been missed but what is the difference between these two chargers? It is noticed that the BT-C3400 is not available until 6 OCT 2014. It is found both on ebay and Amazon. Thank you for any thoughts on the matter.

If all else fails I have a few extra ones!

I am not sure where the link for the “angled ones are”. Your resourceful! If you google the numbers you could find the “angled ones.

Thanks Wolf. I’ll take a look, but it’s more of a minor nit. My 2A wall wart works fine, although my first one from Rdana crapped out on me @ 4x1000mA. charging.

I’m still using my original fan ,it got noisy once and I just gave the housing next to the fan a few flicks & it’s never done it again.
I have opened my opus a couple of times & while it was open I took the fan out & took all stickers off it & sprayed it including the windings with spray on 3 in 1 oil.
Hey wolfdog you sent me link in the other thread for the adaptors from alixpress, they fit good & are right angle.

SIGShooter · 2019-03-23T00:47:42.000Z

My fan also started making noises last year but a squirt of Tri-flow after I took it out fixed that right up

Nev · 2019-03-23T01:05:09.000Z

Is triflow an oil?

Glad to hear that. I did not have time to search the thread because I was on my way to the trail. I am curious,where is the link to those?

I thought I got them all on Ebay.

wolfdog1226 · 2019-03-23T01:23:04.000Z

Where is OP at?!! He started the thread and has not been seen since!!

wolfdog1226 · 2019-03-23T01:36:40.000Z

@Chris DISREGARD THAT link I posted below for the Barrel connectors! The listing ended and the ones they posted are WRONG!!

I have Two spares I can send you if you want. send me PM w/ your address

Yes. I use the spray-on can but you can get it in squeeze bottles, etc. To be honest I haven’t notice much difference in light oils and I think there’s a lot of marketing hype regarding them.

Nev · 2019-03-23T18:33:16.000Z

These are the ones I got a while back , they were just over £3 but now they’re only £1
With these I can pick the opus up & move it around with no loss of connection.
Look what I found on AliExpress

Apologies …. I got crazy busy at work as soon as I posted and then had friends come to stay over the weekend …. I kept meaning to check it but just haven’t had a chance.

I left it unplugged and have tried again and it seems fine now which is really weird, I got 4 x 18650’s and put them all in at the same time and the fan cut in as it should.

I hadn’t put the battery in the wrong way and did try using magnets on the ends before I posted this thread.

Think I may oil the fan anyway as it’s always been noisy, is there any oil I should use … is 3 in 1 OK or silicon spray any better

I’ll also look at the fan upgrade that’s been mentioned although I just want to make sure the unit’s OK before I spend the money on that and find the issue I had was the start of it breaking down and don’t see what else I can do but keep using it for now and see if the error occurs again.

SIGShooter · 2019-03-26T17:49:24.000Z

I used Tri-flow oil on mine last year and it’s been running quiet since then. I think for the most part that any oil/grease would work effectively for this particular purpose.

Nev · 2019-03-26T19:02:11.000Z

I use 3 in 1 spray , it’s a little thinner than the caned 3 in1 oil.

Witterings · 2019-03-29T12:08:30.000Z

Just charged 4 x AA’s with it with no problem … took them out and went to replace with the next 4 and it just said Null on each slot …. definitely not a happy charger it seems

Witterings · 2019-03-29T12:49:40.000Z

Further Update …. Switched it off, left it for a while, switched on and put the 4 x’s AA’s back in, all registered a voltage and left them to charge, fan cut in after a short while.

Left it for about 10 mins, went to check and saw the voltage hadn’t changed on any of them, switched through the display and it showed 2 mah had gone into each of the batteries, checked the time and they all said 0.00 … touched one of the batteries …. another 5 mins and I think it’d of been searching for the fire extinguisher and couldn’t hold onto them as I took them out of the charger so probably destroyed 4 brand new batteries as well.

My conclusion of the Opus BT C3100 is it’s a DANGEROUS POS … really hasn’t been a good experience for me at all.
