They are good are they, I wouldn't honestly know. I think I could get away with lower rpm fans if the ups doesn't have a paddy, as the casing is constantly cold even after its been running on battery mode for a hr and you can feel the air being sucked into the ups though all the air vents. Plus atm I am using eco mode so the inverter doesn't get used unless the voltage shifts 5% or powerloss.
uninterruptible power supply help

Ummm, Can you buy a splitter or a switch? I was thinking something like that would be nice to have if I do buy a generator, Then I could have the ups plugged in to both mains power and generator at the same time and then flick a switch between the 2...
Ive seen a 2600kw generator with AVR and electric key start for £250., I think that would power my ups without the ups cutting off the generators supply and running off battery too often... Does a online ups totally disconnects from the mains and stops charging the batteries if dodgy mains power is being sent to it? I think older line interactive ups's does this, thats why these don't work too well if connected to a generator, because they are always on battery mode. The newer line interactive ups's has a "generator mode".

Well I have been inside the ups today, and its very tidy inside, a bit like a pc. The 4 batteries are on one side of the case at the front ontop of each other, then totally empty the rest of the way back. You could get another 8 batteries in there easy id say.
The other half of the case is full of the electrics, with a plastic sheet that covers them.
Anyway I removed the fans easy enough, and it was a nice surprise to see that the fan plugs wern't glued in.. Here's the fans but there all in chinese, and I couldnt get it translated, so I ordered some noctua 1800rpm case fans. https://translate.google.co.uk/tran....taobao.com/item/562796603918.htm&prev=search Im sure the fans that are in it are much higher rpm, but Im hopeing these noctua's are fast enough and keep things cool.. fingers crossed https://www.overclockers.co.uk/noctua-nf-r8-redux-1800rpm-80mm-quiet-case-fan-fg-040-nc.html. Im not having high hopes for the fans, but I might be presently surprised?
These are the batteries that are installed....... https://www.hardwarexpress.co.uk/csb-ups12460-battery-ups12460-7f2-12v-460w-4858-p.asp
Here are some inside pics of the ups.....

It still looks a hell lot easier to replace then the belkin ups batteries. The main prob is avoiding touching the panel with the terminals on the batteries as the terminal are against the panel,, but then again once the batteries are connected the terminals will be covered. The board id say is sitting about 1cms off the panel on standoffs, so the batt terminals shouldnt be able to touch the board. I might cover that panel with plastic sheeting when I replace the batteries in a few yrs time
The four big capacitors say "CE 1707" if that makes any sense to you. The fans came today and there the correct size, now Im just need my mate to put them in for me and keep fingers and toes crossed that they are fast enough so the ups doesn't complain.

Yeah I was thinking that, hot air could be sucked out more effectively, being in a more confined space with the plastic being there. and yeah the plastic shields it from the metal case cover aswel, why use a metal case cover is beyond me though. Its not nearly as scary as my old ups to remove and put the casing back on, but its still a bit scary with the casing cover being metal
Or get some of that wide electrical tape and stick it directly onto the panel were the batteries terminals sit. I'll be amazed if the batteries are not insulated somehow with the terminals being against the panel. I cannot really tell without unscrewing bits, as they are firmly held in place as you can see.........

That plastic only covers that 1 side and its pegged into those holes on the bottom heatsink, 1 of the pegs has pinged somewhere that I will have to try and find.. Luckily I only have to take off the plastic for changing the fans and not the battery replacement as I can see the plastic cover getting damage if unpeged too meny times.
I didnt mean for you to tell me what everything was inside, but thank you.. I am not great with technical stuff but I get by ok I think. You say its surge protected, it isnt surge protected so the spec says and the guy from the manufacture recommended me to plug the ups into a surge protector
Well my mate put the new fans in for me and guess what, it had a paddy, beeping and flashing away with "fan fail". But now for some reason its working fine now, and I have played about with it, on and off battery mode and stuff to get it to fail again, but it appears to be working A-OK now. So I dont know if 1 of the fans was a bit stiff at the begining, causing the fans not rotating at the same speed and that was making the alarm to go off.. quite odd.
But yeh is not pulling as much air through the case now but I can still feel air being sucked in through the front and sides, so its still moving air through it. I have tested it on battery mode for 20mins or so and the case stayed nice and cool, Plus now my pc is louder then the ups now, Id say the ups is about 50% quieter now then before. Plus the dark screen cover (light dims) came today and now I should be able to sleep ok without having to cover up the screen.
Edit: Im lying in bed now, and I can still hear the fans but its not like having 5 pc's running in my room, its more like having half a pc running

I needed to use the old fan plugs on the fans so I just chopped off the plug and rejoined the wires together on the one fan using tape. But on the 2nd fan I tried just swapping over the plugs, but that kind of failed, as the wires are loose inside the plug, so I will need redo that fan with my mate.
So I have just thought I might aswel buy proper wire joiners and redo both fan, but I will need to buy another plug with the wires attached for the one fan.. Im just wondering how small do I need the wire joiners to be for fan wires as they are pretty flimsy wires?

Well I have ordered some of those jelly crimps that they use on phone wires and some of these that I will join to the fans, as the ups doesn't use the normal pc fan plug.
Hopefully it will make a strong and professional looking connection.
I havent had another fan fail since, I have been making the fans speed up/down and turning the ups off/on a few times,, but I cant get the alarm to go off again.. So no idea what was wrong at the beginning as the alarm went off quite a few times after a few secs or minutes of turning the ups on. The only idea I have is that both fans wern't spinning at the same speed and that caused the alarm to go off, or like you said they wern't speeding up fast enough. Knowing my luck, they will fail now. I guess fans get easier to rotate as they wear in?

The voltage went down to 230v earlier today for 30mins or so and the ups clicked over to online mode and brought the output back to 240v. I think the margin was wider with my old line-interactive ups, think it was something like below 192v and above 276v when it leaped into action.. But if I use the normal mode on this new ups, the output would be a constant 240v and wouldn't budge at all, but it uses like 30watts more power 24/7. So with the energy saving mode (eco) it only uses the normal mode when it has to.
A few days ago someone in our family turned on our circular saw and that jolted the voltage and made the ups click over to normal mode. Im like a big kid with a new toy hehe.... perthertic

Hey I think the power company are going to provide us with a generator for weds. I think its going to be one of those big ones that connects up to the house.. Im still expecting them to bring a portable one, as Im guessing it's going to cost them a fair bit to provide us with one that powers the house and get it set up ect.
There must be a lot of cookers going on at tea time, as the voltage drops to 230 about 5.30 every evening causing the ups to correct the voltage for 30mins or so. I guess the ups will be correcting the voltage all day Wednesday with the generator. But it should be quite a good generator if its one of these big ones though, so the voltage might not be too bad.

Well the guy has just been with the generator and he has connected it up to our meter box so the house has got full power but the guy said we have lost 80amps, so we need to be a bit careful what we use.
The generator isnt making the ups go on to online mode at all so far, the voltage is just sitting at 239v according to the ups. Ah yeah were having a new electric telegraph pole put in, thats why there's no power.

I have redone the fan cables today with my mate..
I got new fan plugs with the wires attached,
Soldered the wires on to the fan cable
Use some Heat-shrink tubing to cover each joined wire, instead of insulation tape
Then used cable sleeve to sleeve all cables together so you cant see the join and looks like I haven't tampered with the fans now either. Plus it should be totally safe now too
It might seem a bit over the top but I want to keep it looking tidy and untouched inside, I probably wouldn't of gone to all this trouble if it was a cheap UPS.. pathetic I know, isn't it?

hi,, just a update... Since having the UPS in February and changing the fans for quieter ones. I have had no problems at all with it and it been running 24/7 with my computer, audio and tv stuff plugged into it (thats roughly every thing in my room) and with all that stuff there still not much power being used.
It complained about the fans after a few days of putting them in, but nothing since. The ups hasnt really been tested yet as we havent had any bad weather yet and the ups only uses online mode when volts increase or decrease by about 10volts from 240v, as it uses more power running it in online mode all the time.
I still wouldn't mind buying a generator even though it wouldnt get used much,,, as it would be real handy to connect the ups to a generator when we do have the odd long powercut

Yeah the Powerwaker is going well, no probs so far and I have been using it 24/7. I have figured out it lasts 3 hrs on battery mode even if there's nothing plugged in to it.
I have all my stuff in my bedroom plugged into it TV and PC stuff, so tomorrow Im going to order first portable generator, as a bit of a upgrade for the UPS. So when I have a powercut, I'll plug the ups into the generator and everything then will be powered in my room no matter how long the power is off for... No doubt the rest of my family will use it aswel during a powercut,, even though they say Im wasting my money.

I was a tad concerned about the extra power a online UPS would use aswel,, but by putting the UPS onto eco mode it acts like a line interactive ups, untill the voltage wonders 2%+/- off track then it switches to normal online mode untill the voltage is back where it should be. I hear my ups clicking to and from these 2 modes a few times a day, (more so at night then daytime). I think most online UPS's has a eco mode to save power/money.
My UPS runs cold and remember I even changed the fans for slower quieter ones... But yeah thats the only problem with a online UPS, the fans run 24/7 and the stock fans on my UPS wern't quiet ones either, thats why I changed them.
