    I love the chipsetfan :D


    No :p

    Even the Aorus Extreme needs a fan ! Happy toasting ???

    Threadripper has very low value. The previous generation motherboard is not compatible with the new Threadripper and it sucked. Threadripper does not matter at all.

    Do we really need that MB chip fan? wont a nice heat sink suffice?

    That's true of ALL HEDT platforms now. When you can get 16 cores on the desktop platform, the premium price for HEDT is a waste unless you really need 32+ cores.

    To be fair, Intel's HEDT has had almost no longevity and has been outlclassed in 2 years by a new chipset for as long as the HEDT platform has existed, so this is nothing new.

    Seeing as X570 needs active cooling due to a handful of PCIe 4.0 lanes, I imagine there must be a substantial heat increase with 64 lanes.

    AMD wouldn't make them if they didn't matter. Motherboard manufacturers wouldn't make mobos for them if they didn't matter. Are you trying to argue against the reality?

    You might have missed the news, but the new Threadripper comes with PCIe 4.0. There's no way to give old mobos it as an upgrade. TR is an enthusiast platform, not a mainstream platform, so aside from competition consideration, the value is very subjective, unlike in the mainstream, where value is what keeps things within the category. That's why it's very acceptable to require a new motherboard when you have an upgrade that's simply impossible with the old one. AMD went out of their way to retain socket/mobo compatibility with the mainstream Ryzen because value is more important in the mainstream, like I already said.

    Let's not feed the trolls.

    It dirties up so many threads I have to discontinue following.

    I think I could replace the VRM on every motherboard I've ever owned with the amount soldered to this board

    most x399 boards expose 64 lanes direct to cpu lanes,x48 for 3-4 pcie x16 slots, 3 x4 m.2 slots and 1 x4 link for the chipset.
    Unlike am4 which only has 24 lanes direct to cpu
    X16 for gpu , an x4 m.2 drive and an x4 for the chipset to be used for io/additional slots.

    The additional lanes should have no effect on the chipset power consumption.

    However, I suspect the reason it needs a fan, is because its the exact same chipset as x570 ,which is a repurposed am4 iodie

    But that's exactly my point - X570 only has 24 lanes, and yet it needs a fan. The only significant difference between X570 and previous generations is PCIe 4.0, suggesting it's the PCIe lanes themselves that add the heat. So, since X399 has more than double the PCIe 4.0 lanes, I imagine that's going to be substantially more heat.
    X399 seems to have larger heatsinks, so, my assumption can't be too far off.

    It's the way of the future. If you want to be stuck with old-gen PCIe 3.0 speeds then be my guest. :p

    the extra power consumption is from the pcie controllers, with the the extra lanes on threadripper , the extra heat from pcie gen 4 would be on the cpu itself,

    And as it turns out there are more lanes connected to the chipset on trx40 , and provides 24 chipset lanes so it may be something else other than the am4 io die(16 chipset lanes on x570). But the point stands, the extra (cpu )lanes on threadripper would not contribute to a chipset fan on a presumed pcie gen 4 X399 board.

    the threadripper IO die is the TRX40 chipset, it is not the same as the x570 die

    no, that doesn't add up.

    It could still be the am4 io die,
    [​IMG]
    It looks like 16 pairs of pcie controllers, on the io die, so it probably has 32 lanes phsyically, much like zen 1 and zen+, and that would work for both x570 and trx40.

    Show me PCI3.0 being a bottleneck in my usage and I will bite. If a GPU could saturate 16 gen 3 lanes then the CPU would not be able to keep up in most cases. Gen 4 is nice but not needed as of now. In 5 years then maybe.

    I didn't say it was just the extra lanes, I'm saying it's the fact they're PCIe 4.0 lanes. So, if PCIe 4.0 isn't the reason for needing a chipset fan, then what is?

    Although I totally agree that there's basically nothing out there that'll saturate x16 PCIe 3.0 lanes, there are devices out there that use fewer lanes and could see a healthy performance benefit.

    Well I haven't seen a Gen4 based NVMe topple any of the Samsung 970 units pro or evo. So again there is currently no "need" for gen4 and Intel knows that so they are not in a rush to adopt it. Gen4 is nothing more than a marketing gimmick at the moment to sell X570 motherboards.
