Could my PCIx16 slot be the cause of 3 bad graphics card fans?

Ok I've got an Asus mobo, this one in fact: - ASUS P5K EPU LGA 775 Intel P35 ATX Intel Motherboard

I've had this mobo for the last two years without any problems.

Over the last year or so, my first Asus 9600GT graphics card went bad (the fan warped & stopped working, causing it to overheat a lot)

Then I got the new one & ran that one for maybe almost a year and then the same thing happened, the fan warped & went bad.

Now I cant not say for sure which slot the 1st bad graphics card was in, if it was in #1 or #2

But I can say for sure that the 2nd time it was in PCIx16 1

Now I've received the 3rd card & installed it in PCIx16 1 and within a little while, I noticed the card was giving off a lot of heat, I unplugged it and upon closer inspection I see the fan was slightly warped again.

I will also say that I didnt inspect the card when I got it to be sure everything was ok, maybe they sent me another bad card...?

Now the fan still turns smoothly, but you can see it starting to cock up & become warped.

I've since talked to Asus again 7 they are doing another RMA for me, so the graphics card is covered.

But I'd like to get to the bottom of things and fix the root of the problem.

Do you think in any way possible it is the PCIx16 1 slot making it go bad?

I talked to the guy at Asus about it & he said it isnt likely as the slot just transfer data & said perhaps it was my power supply.

Here is my power supply: - Rosewill RX630-S-B 630W ATX12V v2.2 & EPS12V v2.91 SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Power Supply

It's only 2 years old as well and powers A LOT of other stuff within my computer without any problems or hiccups at all ever.

So I'm reluctant to blame it on the power supply... but you never know.
