Graphics card bracket restricts too much exhaust need improved bracket design
Does anyone run their graphics cards without an exhaust bracket?
I do now.

MY GTX 580 gpu temps decreased 5C from 79C/79% fan to 74C/74% fan.

Fan noise has become less annoying since air no longer passes through narrow bracket slots.
There is still fan noise and still sound from moving air, except now it's less high-pitch (less annoying).

After experiencing no bracket, I will definately not put it back on.
The stock mounting bracket is a flawed design which unnecessarily restricts exhaust air and creates unnecessary high-pitch noise.

In tests done at legitreviews, they measured up to 4C gpu temperature decrease without an exhaust bracket.

In the picture, you see I also removed the thin metal strip which separates PCI slots.
The weight of my GTX 580 is now supported by my sound card which is installed under it.

You may ignore the fan at the top. It's my attempt to cool the graphics card, by blowing air across the top.

Thats interesting. If i didnt have water cooling, i'd do this.

Edit: Just realized you can't screw the card in...:S

lol Cravin...

I'd say 2 things Partol:
1. That poor sound card - quite a bit of weight on it now. Can you not modify the bracket to still support the GPU weight, but not block the airflow??
2. I'd remove that thin metal strip as well - looks difficult to plug in your monitor anyway - but it'd help with flow

I considered cutting the bracket, down to a stub. However, I am worried about reduced resale value.

Right now, half the weight of the GTX 580 is supported by pci-e x16 slot. Other half of weight is supported by the sound card.
The sound card has a strong bracket, but it's pci-e x1 slot is small and worries me a little.

Right now, it's stable, as long as the case is not moved. I placed a shim on top of the sound card to stop the graphics card from drooping down.

As for overclocking, my GTX 580 is more stable now at 930MHz. Can run dx11 games all day now, with no crashes/freezes.
In the legitreview test, PCB temperature decreased several degrees, which probably also decreases VRM (power circuitry) temps.
And that explains why my overclock is more stable.

I think the best reason to do this mod is for reduced high-pitch noise at high fan speed. The noise is now only half as annoying. It's *almost* like having a new gpu cooler.

My next idea is to mount the external 120mm fan a little lower, in order to pull air out of the gpu cooler, but my headphones cable blocks that area a little.

Wow, that single slot bracket looks nice. I would like my bracket to be a little more smaller. maybe I will cut it myself.

Interesting ! 5*C sure is a huge difference. Might try it out on my next GPU :)

Thx for sharing ! /thumbup.gif' class='bbc_emoticon' alt=':thumbup:' />

Using cheap wire cutters and pliers (because I dont have good cutting tools), I cut the mounting bracket to a "stub bracket" which is still very strong and easily supports the GTX 580's weight.

my 2 PNY GTX 580's have the same high flow bracket, didn't know they were called that or that you could buy them as i thought it was the standard bracket.

Same concept as the "high-flow bracket". Yes, it does work. I would not recommend using bulky GPU's without any bracket though, as the weight of the GPU can damage the PCIe slot.

High-flow brackets are a rip-off in my opinion. Not because they don't offer an advantage, but because they can be made out of a standard bracket with ease. Standard bracket + dremel = high-flow bracket. It's such a simple mod that's it's not even funny. If you have a steady hand and half-a-brain, you can even make it look professional.
