Question Asus Rampage IV Black Edition benting (southbridge area)

Hi.

So, long story short: RIVBE board benting a little near southbridge and i suspect massive southbridge backplate is causing it since its clearly can be seen from behind the MB and I\O panel area. Not enough space for it, lifters too short. Nothing too serious, like 1-3mm max.

Another thing ive got: two lifters near right lower side sitting not quite straight, just about a couple degrees away from being in place, and the reason i didnt noticed anything during installation is because motherboard got right into the holes and all of the screws were tightened up correctly, without any scratches or other weird noises.

The reasons why im typing this nonsense here instead of fixing it? Well:

1) Rig almost completed, ive been assembling it part by part for two months already. The only thing left is graphic card, waiting for a local mail serivice to deliver a rack. Thats why this thing got my attention.

2) Quality of the case: ive made a mistake and bought pretty cheap case to put E-ATX motherboard, shouldve gone after premium. Those lifters ive mentioned didnt have a carvings, thats why all got messed up. Brand invested more cash into useless tempered glass and painting and nothing on getting tower work out of box: it even waddled, i swear. At least ive fixed it. I wont play name-and-shame unless someone ask me what case exactly ive got.

3) Can't find my special screwdriver for lifters, guess i've lost it due to immense amount of repairs done in my house for last five years. New one cost a lot and i wont be able to find the exact one since all this worldwide situation affected logictics in a bad way and im living far away from big cities.

4) Ive made some custom adjustments to this case and it would cost me several hours of non-stop disassembling and assembling it back. Plus two-sided scotch tape, nerves and chance to break something since MB itself huge and heavy enough. By the way, used cases in my country is dead cargo because of the cost of delivery, stuck with my previous for the same reason.

5) The most infuriating one: due to E-ATX lifters never had a proper carvings in the holes and poor quality of case metal itself there is a good chance those holes wont allow me to re-screw them in a way i shouldve earlier and ill just cut too much and damage metal permanently.

Obviously, i couldve 'just' bought a new expensive case, screwdriver and got it all installed again, but i'm out of time, money and patience.

Will it affect fiberglass and damage something on my motherboard over the time? Not like ive tried to check my pc parts anyway, im sure everything shines for now.

Since Rampage IV Black Edition is a top-tier quality, super durable Asus MB and got three (!) backplates on the back, my questions are:

  • Again, can it affect fiberglass structure over the time, lets say, 5 years? And damage something critical on MB turning it dead.
  • If it will, how safe for thermals if ill just remove southbridge backplate?
Id prefer to speak with someone from repairs wing or anyone who got same situation(s) over the years since the only thing im lacking in this matter is a lot of practice.

ill throw some screenshots a couple hours later, thanks in advance!

Hi, im just a normal person ( I actually dont think there are any repairs specialists here from what i have seen. Though some of the Mods/more experienced users do have years in the industry.

The main concern i have is weight. What components (Especially gpu ) are you throwing inside?

To answer your question
The PCB should be able to take the weight but there is not promises on whether it will affect anything. There are chances it could cause traces to lift/delaminate. All that extra stress has to go somewhere.

As for the backplate, Its normally just a more aesthetic and design choice. The main purpose is to secure the heatsink in front since cheaper board do often make do (and survive ) with just anchors. I would be more worried about lack of mounting pressure on the heatsink and potentially a weaker structure there since the backplate does contribute somewhat to the rigidity

Weight is significant, but i wouldn't worry about that: CPU cooler mounted correctly, all screwes gently tightened, graphic card will be laying on the rack to prevent it from benting as well. Cooler - Noctua U14S w 2 fans, graphics - gtx 1080 ti vulcan ad.

Backplate function depends on manufacturers: fe backplate on mine version of graphic card used to prevent CPU heat from spreading onto GPU and such. To make it work like a heatspreader, user must remove thermal tape on the back of it.

Same goes for old high-end boards like RIVBE: it got massive heatspreaders on SB, NB and power lines. Whole MB weights like a truck, i swear. Southbridge backplate rigid factor and overall quality are what makes me think motherboard will be fine, but still.

By lifters you mean standoffs? Use spacers to get the correct height

A bent motherboard can get faulty over time. Solder joints and vias could break more likely
I cannot, as i said, southbridge backplate prevents it. This is why im thinking about removing it completely but it will require removed SB front heatspreader: backplate's screws are right under it.

Off-topic: is there a way to throw in some screenshots directly from my phone and not a link?
