I've been eyeing this for a while, this month they had another price drop it seems for the 420 version

I've been meaning to upgrade my 10yr old AIO for a while, just noticed this weekend that it was idling at ~85 degrees. Definitely time…

Do note the 280 and 360 seem to perform quite similarly, it might be worth considering the smaller one for case compatibility for future and current builds

    Seems to be a good price and good timing for me!

    Planning to build another rig and use an AIO for the first time - would it be advisable for a front mounted or top mounted radiator?

    Just FYI these are the thickest of the thick, that's why they're so good. Check your ram and vrm clearance as well as any hdd bays.

    I had to return mine bought for fractal define 7 in storage configuration.

      I should've looked into it more carefully, instead of just checking radiator thickness case compatibility.

      I ended up installing it in a pull setup + slightly janky fitting because of how thick the radiator is length wise too

      • teacherer on 19/11/2024 - 11:39

        That's a shame. It is tricky to test without having the equipment in front of you, to be fair.

        I ended up with a EKWB CR360. Pricey, pretty, no complaints.

        I would have loved to have fit the LF3

  • Master Bates on 04/11/2024 - 12:21

    Stupid question incoming:

    I have a 360 AIO that's been running for several years, would prefer to have 140mm fans to match the rest of my case fans.

    420 AIO won't fit. Should I go with 280 for matching fan size or am I doing myself a disservice?

    (This is coming from someone who is always inclined to choose function over form).

      Performance wont change much at all.

      I assume your options are 3x120 and 2x140?

      I would just stick with the current 360

      • Master Bates on 04/11/2024 - 12:30

        I assume your options are 3x120 and 2x140?

        Yep. To be honest these LF III are probably too thick for my setup without a case change anyway.

        I would just stick with the current 360

        That's my logic too.

        • Beyond on 05/11/2024 - 00:06

          When you insert your 360, is there a gap on the side of it? (I mention this because you said 140s were your case default, so I assume the 120s on the 360 AIO opens a gap)

    • kid-vhee on 04/11/2024 - 12:27

      Function wise; 360 rad has about 43200 cm3 where as 280 is 39200. 360 should have better cooling. Roughly 10% cooling area difference vs price cost to buy new cooler and lost in cooling capacity your choice.

      There are 120x140 fan adaptors, but you'll drop two fans instead of 3 if you used them.

        Thanks. Should have know these existed, if not 3D printed.

      • kid-vhee on 04/11/2024 - 13:33

        also note my math was incorrect. should be mm3 - otherwise divide by 100 - not that it matters in terms of comparison here.

      About the only small reason I could see to downgrade from a 360 to a 280mm rad would be to get 140mm fans, as they can push more air per dB of noise. So you could potentially end up with a slightly quieter setup.

      Is it worth it when yours is already working? Especially with the marginal downgrade in cooling performance? Only you can answer that.

        Logic tells me no. High chance of breaking something whilst tinkering for purely aesthetic reasons, when no-one is actually looking at it. That's why it was a stupid question on my part.

  • BaccyChan on 04/11/2024 - 14:25

    Once again I never really understand a cooler like this unless you have a 4090.. It's $125 -> $159

    My 6700XT I bought ages ago cost $550, but now a 7800XT would be $700 on special..
    https://www.pgrid.com.au/gpus/radeon-rx-7800-xt
    So instead of spending $159 on a cooler you could just massively upgrade a GPU in a new build..

    I currently run a 7900GRE/5700X3D with an AK400 cooler which is bottom barrel really, my cpu has never gone over 70c (compiling shaders etc) and the GPU sits at like 65c being pushed hard.. With all my fan curves set to around 40% and boring old stock case fans + 2 exhausts.

    Do people value the look of them this much? They don't even have any benefits over a air cooler besides running a bit quieter as they tend to break too.

    • Axelstrife on 04/11/2024 - 14:42

      This is a CPU cooler not GPU cooler.

      AMD is MUCH more efficiant than intel these days, my 14700k would not be cooled by that ak400 and needs a AIO.

      • BaccyChan on 04/11/2024 - 15:27

        Yep, which is why I listed my CPU temp as well. Was more just saying I keep seeing people spend so much money on these giga cooling set ups. I wasn't aware that intel needed that much more cooling, I've only had a 3600 prior to this and then before that I was too young to even care about all this anyway. Pretty rough that you need to put so much more effort into cooling them then. They certainly do look pretty cool but it's probably the last place I'd want to put the hardware money into which was where I was coming from.

      If you are trying to understand it from a practical perspective, it's actually not that complicated. Not everyone is running a 5700x3D.

      My CPU came with a notice that they don't include an air cooler because they expect you to watercool it. I'm not up to date with current hardware, but I'm pretty sure there are even CPU's out there that draw almost double the amount of power as my CPU…

      Then there's other stuff like overclocking

    Average coldplate/waterblock at best on LF3 in teardown,
    worse than mirage / galahad ii etc, around comparable to Asetek G8 and slightly better than CoolIT

    Mainly compensated by the 50% thicker 38mm radiator (case compatability issues, restricts push/pull etc)
    With this extra thickness you can mount an additional set of fans fo the other 27mm thick aios instead, which is rarely shown in testing but would be better.

    240mm Mystique / Galahad II is already enough for 300w+ on intel and 200w+ on AMD below 50% fan speed, especially in pushpull.
    Would get those over this, better blocks and pumps but with thinner radiator.

    sidenote:

    Radiator capacity barely matters in current-gen CPUs (the lowest end 240mm can already dissipate ~400w with <20c coolant delta, no current gen CPU draws 400w)
    Most AIOs and air coolers are bottlenecked by heatpipe/coldplate manufacturing (the ability to draw heat out from the CPU and into the finstack.)

    e.g. 120mm radiator + Supercool or Iceman Waterblock beats every single 360mm AIO right now by 10-20c on am5/lga1700 due to the far better waterblock.

    the 360mms only start taking a lead on GPU mounts like Kraken G12, or massive EPYC / XEON cpus with low density, where heat transfer is not a bottleneck and the larger radiator actually comes into play.

      so basically none of this matters unless
      1. you care most about noise
      2. your schizo

      • HPdeskjet on 04/11/2024 - 19:42

        Yes

        I like pulling 400w from my cpu without it turning into a jet engine

        The schizo part is where I make the cpu pull 400w for 0.00000005% extra perf

          My 5900x on this 420 AIO never hits thermal threshold - only EDC current threshold. I quite like this cooler mainly for the fan on top of the block to add VRM and memory cooling.

          • HPdeskjet on 06/11/2024 - 17:58

            @kid-vhee: 5900x has no density issues, you can cool it under a good 120mm AIO @ ~220w OC without ramping the fans much (stock is 142w).

            Tested: EK D-RGB (SPC Pump) 120 w/ a12x25 <1500rpm | Alphacool LT120 w/ a12x25 <1300rpm

            Any even below average 240mm should have no issues with a 5900x at full PBO boost.

            Something like a 5800x is where am4 gets difficult, single CCD = 2x heat density of 5900x at same power.

            it's rough for any non semi-custom AIO (Fractal Kelvin, Alphacool LT, EK-MLC) etc regardless of radiator size.
