Full Version: Unused 5.25 bay, place for GPU?
You're currently viewing a stripped down version of our content. View the full version with proper formatting.
I have this huge case of which none of the 5.25 bay slots are being used.  My Board could allow 3 GPUs with out pic extender, if I didn't care that two of them would be really close to each other.  That got me thinking, what if I used an extender and put my third GPU in the top BAY slot which conveniently has ventilation at the top.   

Then I stumbled on this

curious as to peoples thoughts?

That web page says that it is compliant with PCI Express 2.0.  Is there a newer model that supports PCI Express 3.0?

Also, it only transfers a PCIe x4 signal.  It seems to me that you would want it to be PCIe x16.

Instead of this, why not just stack your 3 GPUs after removing the backplate on the two that are close to each other?  If thermals are a concern, you can get a flexible fan inside your case that blows air directly on the two cards that are right next to each other.

I had a fan like this one on a previous build and it did the job.

It mounts with a single screw.  I don't know if Antec still makes that fan model so get it while you can.
I wasn't suggesting that I get that particular device, just really using the bay to house a card.

That said can you point me to a tutorial on removing the heat plates? I thought they were there to help draw away heat, like a heat sync. No?

Interesting device!  I've seen risers but never anything for drive bays.  

Thread is getting old, but I thought I would confirm:

Many GPU intensive applications don't need a fast bus.  I can put a modern card in my old Mac Pro that only has PCIe 1.1 slots, and certain apps run at almost full speed.  Of course, if there is a lot of data going back and forth to the card, this won't work well.  

Isn't hashcat mostly running in-gpu with relatively little data going over the bus?
