    Yea i know that hence why i said if staying with air. AMD's stock boards also seem to be decent as well. If going air though i would not touch a blower card.

    had a blower style Vega 64, i like the boxy type of cards and it was absolutely fine at 1080p, however, the jump to 1440p made it pretty unbearable so i got rid.

    I don't agree. With a single blower, your videocard PCB experiences significantly worse thermal density upon itself. Because of the configuration itself, you get less heatsink volume, and all the heat accumulates there.
    With 3 axial fans, you get lower thermal density and much faster heat exchange between the components on the videocard PCB and the surrounding area. Your case has several more axial coolers to help.

    See, if the blower cooler was double, like two smaller blower coolers and somehow larger heatsinks, maybe it would be the more efficient design.

    I am especially excited for tonights presentation from AMD. This will determine the route I go down with my new build. In short, if they reveal a high powered RX5900 which performs as well as the Radeon VII or better then I am all over it. It will be my GPU for the new build. If they do not, I'll buy a Vega 56 to tide me over until a heavyweight NAVI comes out.

    However, I can't help but feel (because this makes more business sense to me, at least) they will show/reveal 2 x NAVI cards to compete with/slightly out perform the RTX 2060 & 2070. Leaving the Radeon VII up to slightly out perform the RTX 2080. Then replace the Radeon VII at a later date with a NAVI varient. For them to release a Radeon VII replacement now seems like a huge bird flipping to those who bought one already.

    However, if its dead in the water, maybe its better to replace it already.

    Basically have a good case that moves air and a 2 or 3 fan design is way better than a blower. With my Red Devil 64 and all the hype about Vega being a volcano i have no problem what so ever. I use the stock profile as well and temps never reach 70. If i set it up on the undervolt with an aggressive fan profile things get much better. No need though as i game with a headset. My Crosshair Carbide 740 does the job so i don't need to worry about putting any card in really.

    You agreeing and disagreeing with yourself. Re-read what I said not once have I said blower fan is better than a custom fan config. But what I will repeat again is you making out that blower fans are so much worst than they are! It really comes down to the user and realistic expectations!

    Again I will say it out for you!
    If I take my VEGA 64 blower fan and try and reach clocks of 1600+ all I doing is hitting unrealistic expectations, in turn, a hotter GPU and more noise levels! If I keep it at clocks that a realistic like 1500 then the GPU remains cool and noise level is on par with most coolers. My GPU doesn't go over 70c on the core and 80c on the HBM and noise level is good "Obviously what my noise levels vs yours will be much different"

    Even worse is that every reviewer will get an awful blower card, then Navi will get a reputation for being hot, loud, and underperforming, which will become the baseline benchmarks when comparing against nVidia cards.

    Doesn't matter that X months down the line you'll be able to get a cool/quiet/better performing card, all people will see is the 'stock' card performance.

    They did the same thing with Vega, and 480, and 290... :(

    A decent noise cancelling headset solves all those issues any how :D:D:D. I find it hard to game with surround speakers as i don't feel like i am gaming properly unless i wear a headset.

    Yea seems to be the case for a long time with AMD. Need a generator and can't game if it's not winter with the window open :D:D:D:D:D

    You say that blower coolers have lower thermal dissipation capacity.
    And this is enough said.

    It would. But I don't like wearing headphones for extended periods. Everyone is different.
    I love my 5.1 surround system.

    I did? Where? LOL I said Blower Coolers are better for the overall system cooling! Because they push the hot air out of the case rather than into the case. Depending on the size of the case and its fans a custom cooler on a GPU putting all the hot air into the case can actually affect other hardware like the CPU/Motherboard and even the PSU can get hotter.

    And you said GPUs experience 'higher thermal densities' under a blower cooler. Cooling doesn't change the thermal density - Voltage and clockspeed do.

    Here:

    and here:



    I disagree. You conveniently skip the fact that with axial coolers there is less heat and lower temperatures overall. What with a blower cooler is heat, with an axial cooler is just warmth.

    What? I think you completely fail to read what I saying!

    You can have two VEGA 64 GPUs one blower and one triple fan running at the same speed and voltage they will both give of the same amount of heat! That heat doesn't just magically disappear! Core Temp and HBM Temp is only part of the story, the TDP of the GPU remains the same its still 400w worth of heat that must go somewhere.

    Blower is good for 2 reasons
    a) Cheap to make reference cooler for us watercooling, no need for expensive coolers.
    b) Many mATX and mIXT builds require blowers. Hell we even saw the amount of complains with the Turing cards, people were complaining even in this very forum, that the reference is not blower design.
