Yes, it will damage both cards in the long run. Find a smaller 50x50mm heatsink, also swap the cards.

PS. Increase the RAM to at least 64MiB.

And/or look for a different motherboard. The BabyAT form factor always has challenges with some long cards, but a lot of boards have the CPU lower down, impacting a couple of ISA slots and leaving one or two PCI slots free for longer cards.

There are also shorter S3 Virge cards - in particular cards by Diamond and ELSA are frequently not much longer than the slot itself. I see the Diamond Stealth3D 3000 pop up quite a lot. It also has very good analog image quality (commonly poor on S3-based cards)

To max 64MiB. This board has an i430VX chipset and can only cache 64MB. If it's just about playing games, no game that would run well on this setup would need more than 64MB.

Yes, I completely forgot. I'm just thinking about the K6-2.

What's wrong with swapping the 2 cards?
The vga is shorter

I did try that, but the RAM sockets on the S3 are taller and cause more flex on the end of the card than what the V2 is experiencing.

I’ll be on the hunt for a smaller heatsink, my focus was on keeping the K6-2 nice and cool, though from what I’m reading about 3Dfx, these cards took on a lot of the processing power and relaxed/offloaded the CPU.

I did have a Radeon 7000 PCI in here, but having the Voodoo2 is a 27-year dream-come-true.
And I wanted to run Glide games as natively as possible.

The HOT-591P has this same issue with the Voodoo2 and Shuttle's suggestion is a low profile heatsink

Which leads to the question: why did high profile ones exist then? Quieter fan, overkill because they're Socket 370/A era ones, or cheaper because the smaller ones need more expensive/more thermally conductive metal?

I'm not sure there's any real risk.
The bent looks very light.
