    So the link includes a code so the 'sponsor' knows it was their work?

    I tend to use fully synthetic engine oil, but perhaps I should try automatic transmission fluid as the detergents in engine oil keep particles in suspension.

    Once properly oiled I doubt it will...

    Fan bearing

    I have an AVC fan that has

    1B1S BEARING

    written on the label

    Does this mean one ball, one sleeve bearing?

    I have a similar, but older, HP with a Core 2 Quad and GT 1030 and unfortunately it can play Far Cry 4 without issue; so I had to upgrade my Son's PC to stop him taking mine over.

    So I guess it...

    Looks like your supply for the HP 800 G1 is 12V only and so cannot just be replaced.

    Powering the card separately would be a bit of a hack, and they may be cheap because they have been used for...

    Don't listen to me, my computers are 10 years old and I just keep them running. On some fans one can get to the bearing under the label, and then a bit of engine oil brings them back.

    It takes all...

    The Yate Loon D12SM-12 is $7 on ebay

    You could fix the supply and then keep it as a spare

    A very valid point, but the 'table' is very simple; the extra voltage goes in proportion to the measured current. In theory a small transistor can do it.
  14. The sense wires carry almost no current, so...

    The sense wires carry almost no current, so putting resistors in the sense wires should not do much; the resistors need to go in the main wires.

    Much easier would be to just control the voltage on...

    So if 0.5V is lost across the cable, the supply will deliver 12.5V?

    i.e. I mean going beyond just regulating 12V

    I was suggesting doing the voltage correction WITHOUT sense wires.
  17. That is non trivial as its job is to compensate...

    That is non trivial as its job is to compensate when sensing a low voltage. i.e. as the voltage drops it compensates, but that needs to stop at some point.




    Actually the whole thing can be...

    My worry is the response; if the supply senses the voltage is down it pumps up its end, but then there is the concern about what it does if it senses zero.

    Of course they are not necessary, a lot of supplies don't have them.

    If the resistive drop takes one out of spec (or non-competitive) one has two options

    * heavier cable
    * sense wires

    From that page, this graph really annoys me; that strange kink in the curve at 50%... does not exist, it is an artifact of plotting 30% of the range in the left half and 50% in the right half.

    but since the UPS charges them, I assumed they were just sitting in storage.

    For me, even one non-recoverable bit is an issue; you would probably not have notice such data loss.

    Even a normal hard drive can have one non-recoverable bit in 10^14 (that's just 12.5 TB)
