    Isn't it the number at the bottom of my screenshot? v2.20.1271?

    Smart fan implies PWM, but PWM doesn't imply the wiring is the same. Here is the pinouts for the TC-886 fan headers:
    As long as the fan you buy has those pins in the right place it should work. Those BTW are really pretty standard, I don't know why anyone would find a third party fan that wouldn't match, unless they were trying to overdrive the rated power.

    Sorry no it doesn't match the numbers I have for this model. It'd be in the BIOS MAIN tab.

    Thanks Billsey but I'm afraid it's not going to be too useful when shopping as very few manufacturers (and from what I've seen til now, none!), give out this info on the specs of the fans. In my case it's a cooler I'm after, so heatsink + fan.

    There's a newer BIOS firmware at this link that might reveal the PWM description. However, in my opinion, it's too risky to mess with BIOS firmware for a machine that's otherwise functional just to see if the words pulse width modulation appear.

    Even if all the specs and probes suggest a can't miss slam dunk, I still accept that there are no 100% guarantees for anything. So if it was mine, I'd just get what I think has a little better than halfway decent chance of working from a vendor with a good returns policy just in case it doesn't. If however I couldn't accept anything less than 100%, I wouldn't try to change it.

    You make a good point JackE, so I'll be bold...I found a decent cooler (Arctic Cooling Alpine 12 LP) for under 10€ so I'll give that a try.
    Thanks to everything for your kindness & patience!  :)
    I'll be sure to report back so the info will at least be out there for others.

    This one? For that price, I'd try it even if it wasn't returnable!! :)

    Amazon has lots of reviews and tips on changing. It seems a matter of taking your time and not over torque any screws. Good Luck and keep us informed.

    JackE...yup, that's the one. My thought as well, at that price, what the hell...the benefits are worth the risk.  ;)

    Larryodie...thx, dully noted but I'm not too worried, it's not my first time replacing a heatsink.

    Cheerio! I'll report back around the last week of July which is when I'm getting it (on holiday before that).

    Disappointing...I could not place the Arctic Cooling Alpine cooler because it wouldn't fit! 
    The Acer MB has some screw fittings coming through it to which the native fan is attached...and to which the Arctic cooler could not be attached because the push-pin system that the Arctic cooler uses is too wide to fit in the those Acer screw fittings (best word I could find to describe it). 

    I presume the Arctic cooler expects to be placed directly through the motherboard and from what I can tell, those Acer screw fittings that come through the MB cannot be removed! I tried turning them expecting they were maybe simply screwed in but to no avail.

    Another of those really non-standard annoyances you come across with ready-built PCs. Pretty much all my previous PCs were always built by myself, this was my first and last ready-made PC I'm getting! 
    First headache with the finding the proper RAM now I can't even place my own cooler!! 😠

    They do sell them with screws or a local hardware store or Ebay should have some.

    Could you possibly use the screws from the old unit ?

    Hmmmm? Pins look like they could be made to fit the Acer standoffs using my shop tools.

    I'd look at just removing the push pins and putting screws in instead, perhaps with washers if the fit isn't perfect.

    Screws & washers are so 'old school'. Everybody uses them. I think Velcro dots from the HomeDepot are where it's at. :)

    Really? I still cannot figure out how Velcor dots can be used to solve @chumbo's push-pin fitting problem.

    Thanks but...none of that helps. I'm not going to start DIYing and trying to find screws that fit and then figure out how to attach them to the cooler or whatever other solution involving uncertain modifications.
    I'm done with Acer and any other ready-made PCs.
    Thanks for trying and chiming in.
