I bought a "new" Asus 7950 DirectCUII Top off a auction site last week and finally got around to installing it today. On opening the box, i noticed some bits missing, dust on the fans as well as marks on the PCI express plugs showing it had clearly been used :rolleyes:

On installation, it works "fine" however when the fan speeds up from 10-20% upto about 24% it starts to make a rattling noise. I solved this by supporting the card so it sits straighter and doesn't sag like it does... However this caused another issue. the temps went from low 50s into the 90s in the space of seconds. A quick google shows that is is a common issue, that the weight of the heatsink is too much causing issues with contact on the GPU. :(

Im not sure what my options are, but the fact it was advertised as "new" when it clearly wasnt, and also the fact its "broken" surely i can return it. Big problem is getting my money back though.

Is there a way i could fix it myself with better screws to hold the heatsink on?
 
You have massive protection as a buyer and I would be asking to return it on the grounds it was sold as new and clearly wasn't. Open a case if the seller refuses and claim your postage as well.
 
Just make a bracket to support the back end of the cooler to the card, then a flexible support to the case.

If it works fine, I can not see a new one being any different or any other cards with massive unsupported coolers
 
I'm leaning to trying to fix it rather than return it really. Runs really well untill I touch the heatsink and it's not often I'll be doing that. The noisy fan might just be loose or too close to a cable.

Shocking they didn't use more screw holes to hold it on!
 
£210 so a ok saving.

I used some washers to attach it and it seems to run fine now... Gotta do some more testing. Running at 975/1300 at the moment, 59c while using furmark, although it does have an annoying stutter.

is that cooler compatable with the Asus board because i heard its not a reference card. I may go back to watercooling soon though.
 
You might want to double check the website but it it only cools the core and the memory is done the stick on heatsinks id guess its all about the hole line ups so it should be fine. Or as you say stick in on water

Yes, they all just secure with the 4 fixings around the gpu core...shocking is an understatement.

Spend some time, maybe a bracket picking up on the end of the heatpipes down to the board would be nice, there are already holes in the backend of the Card.

I managed to use some washers to fit it stiffer to the board. All seems good now, and runs cooler!
