I bought a 7900gre is this safe to use to prevent sagging or do I need to buy a bracket?

  1. Aslong as it doesn’t fall into the fan and blow up your whole pc 🤷‍♂️

    Can also get a fan grill to reduce the risk if you don’t get a bracket

  2. I’d be concerned about it deforming the frame.

    Look at the Lian Li GB-001 or GB-002 for a motherboard stand-off mounted bracket, or get a cantilevered bracket that mounts to the PCIE brackets

    I would add a spot of super glue where it touches the fan housing. You do NOT want that vibrating and falling into your fan blades. That fan could be toast

    With heat in constant use it will bend the frame of the fans. I would try some thing else

  5. _Judge_Justice

    Use more legos, just span the entire width of the fan, the outer walls of the fan shroud are sturdy enough.

  6. I use a hand grenade so this seems relatively safe.

    Creative problems solved by creative solutions. Looks good to me

    Yeah why not! Post in r/redneckengineering

    Might wear on the plastic in the fan frame over time so it eventually gets a bit crooked and starts whirring against the edge.

    Use a wide bottom on the lego so the weight gets distributed against the edges of the fan frame, and not the middle, and you’re good.

    Lol sure, unless you move your computer around a lot. Otherwise it should stay where it is.

    I didn’t know lego had other purposes

    Could make a LEGO bridge spanning from the glass to mobo tray sides of the fan shroud. Could make it a few mm short and add some sticky foam pads. Doubling up the removable pcie slot covers leveraging the GPU shroud also solves most sag without bracing.

    a small card wont have much sag. even without the support it will be fine

    There’s no point puttinga fan there anyway. Instead of fan use a stand.

    The inside of a computer especially near the GPU/CPU can get very hot. 80C is the failure point of Lego material which is below the thermal throttle point if you are stressing your GPU. Now that is board temp and not air temp but I wouldn’t be comfortable having them in my case without a thermal reading nearby.

    And note even if it never actually hits 80C+ the thermal stress of being repeatedly heated and cooled will eventually lead to cracking, it will never be a long term solution/require maintenance.

    If you have a 3D printer or access to a 3D printer you could make an anti-sag lift doing something like this. Made it for my SFF build. It uses pegs in the back to secure its self to the back of the fans. As a bonus its also designed as a cable raceway to keep the GPU power cable thats under routed in this case from ever possibly touching the reverse blade fans i have in the bottom. Opted to not stretch it the full length of the fans for aesthetic reasons, a bit of velcro tape prevents any wobble room and once the gpu is sitting on it its firmly in place.

    unless you have some heavy vibration that will cause the lego to shift on its own and fall into the fan, naw… you good.

  18. Competitive_Ear_5202

    Yeah, props like that should be all right

  19. Heck why not run make the gpu legos too😂

  20. TheScreamingFart

    Lol I did this with my old rx 580 for like 3yrs it’s fine.

  21. 3mera1d_and_crap

    Get one of those Lego 8×8 plate grate pieces and put it under the support.

  22. mandatorysin

    It’s basically what I do so it must be good

    Basically, I’m not sure if it’s a good idea to put a pressure from the corner to the center of the fan in that way.

    What you need is a propper Anti-Sag 🙂

    Another thing, I’m not sure that you’re really need those 3 fans under your GPU, it’s isn’t really necessary to add that many case fans, they’re basically noise makers (unless they’re the only intakes in your entire build).

    In a proper fans configuration, a slightly positive pressure would be the best to keep your system on the right temps.

    Check the temps while they’re working, and check the temps while they’re off.

    (Both checks in idle and under load as well).

    If the temps are the same, then you can happily remove one of them, and make a room to a proper Anti-Sag 🙂

    For now. One bump could make a spectacle. A commenter above mentioned using a longer span. Do what they said for sure.

    very risky, the fans might cause tiny vibrations that might slowly move the lego around, and it might move just enough to slip through the gaps.

    get a bigger stand, or find a way to make it now move, maybe tape it to the fan. Since the vibrations wont be strong, a simple tape job should be fine.

  26. Why not make it 2 or more studs longer then you’d be fine for sure
