The end of the (upgrade) road?

[Macca]

I have a cupboard full of them, but I like the BB3.
It is a challenge to conquer.

The funny part is that the noise is not audible when a record is playing, but I know it is there.

I can relate that, sounds like me

I have managed to modify the UPS (in an easily reversible way) to accept an 80mm PC case cooling fan.
The best for an airflow\noise compromise is the Noctua NF-A8 which will give me 32.67CFM with a noise output of 17.7dB(A). I expect it to be a little noisier in the case, but I may take my dremel to it open it to ease airflow on the back, and fit a fan guard.
The new fan arrives next week.

Nice fans Noctua's - been using those in my computer builds for over 20 years now. Even when you can hear them, their noise profile is pleasing.

[CageyH]

I am a noctua fan as well, or should I say I am a fan of their products.
I knew what fan was going in the UPS, I just needed to work out how to avoid a fan error.

I currently have a 140mm low speed case fan fitted temporarily, and there is no fan error, so I think my mod should work nicely.
I used one of the old capacitors from my SL1200 for the mod.

Isn't it great that we now have a tool that can collect together all the bollocks ever posted on the internet and distil it down into one bite-size chunk?

What did we ever do without it?

We learned and memorised things.

We learned and memorised things.

That's very old fashioned now Rob . . .

[CageyH]

I have removed the stamped out fan protector, which is quite restrictive and probably caused a lot of the noise from the fan.
I now have a big 80mm hole, so with a quiet fan, and most importantly, a very low load, the UPS should run quite happily.

When the new fan arrives, I will install it and monitor the UPS temperatures to make sure I do not cause it to overheat.

We learned and memorised things.

But I thought the point of AI is so we can enjoy a bit of cognitive decline while still getting stuff done.

[CageyH]

UPS mission complete. A Noctua A8 has been installed, and the UPS is near silent.
I have also enabled the temperature warning in the UPS, so if the fan is not shifting enough air, I will replace it with a fan that shifts more air.

[CageyH]

I now have all,of my source equipment r7nning from the UPS.
The total load is less than 20% of the 700VA capacity, so I don't think the temperatures will be an issue.
The best bit is that I know have a steady 230V arriving at my equipment, as the UPS is basically a mains regenerator.
I have not heard the occasional hum/buzz since I plugged the BB3 into it, but that was only 4 hours ago.

I need to have a lo0k at my Power Inspired AG1500 at some point, and see what is going on, and make a decision to either scrap or repair it.
