Yeah, I actually saw people claiming that these did not need cooling. It did however seem like these parts (indicated with the read arrow) had exploded in some places as well. Like you can see in my pic, there is some difference between the layout of these. The small resistor (I think) in the middle blew up on my card.

The little squares are slave drivers for each phase and shouldn't require any cooling. The mosfets they blew up do require cooling. At least these poor quality fets do...

Now nVidia would tell you that these are high efficiency mosfets that can handle the high amperage their 500 series cards need. Doesn't look like these new 'high quality' fets are cutting it for them.

This has gota be better in terms of cooling the VRM.

Deccent screw on base to cover the lot all in one go,i think it would be better as theres a larger area to help get rid of heat.

No glue in sight either

Clearly,just a shame to hear of similar problems with the 590 as well.

I´m considering going all the way and getting one of these to help wipe my tears away: http://www.gainward.com/main/vgapro.php?id=454. 3 gigs of ram should be a nice addition for me, as I play some games with wicked high graphics mem requirements (Arma 2).

If you guys could help me sniff out any potential problems with these cards (what fets they use and etc) Id be eternally grateful. I am a slowpoke with this mac.

Even if it's a ref PCB 580, you should be OK. They have 6 phase GPU. The problem with the 570 and 590's are that nVidia thinks the fets are high quality enough to handle the GPU with only 4 phases. The fets would be ok, if there were enough of them.


I find it really funny watching nVidia scramble to nueter the drivers on the 590's. If 570's would have blown up in reviews they would be getting the same attention, but guess nVidia thinks they can sweep the 570 failure under the rug.

Ok, thanks PizzaMan. Thats comforting. I humbly bow in thanks for all your insight regarding this matter.

Edit: Think I´ll go for the Asus directcu II instead of the Gainward, due to component quality being pretty much guaranteed (I will never look lightly at VRMs before purchasing a card again).

Sucks bro. Might want to look into the DirectCUII VRM cooling. They have a small strip which gets cooled passively.


If you still have the AXP why not get a reference 580 and look into a different VRM cooling method such as modding the stock plate or getting VRM heatsinks from a different company.

Yeah man, It sucks. Especially that I dont have a proper pc in the meantime. To be honest I dont feel like doing much modding or custom cooling solutions for gpu's in some while. I can see myself oc'ing the heck out of the directcuII, keeping the stock cooler intact, without actually having to worry about warranty. Asus advertise volt modding with their DcuII's as well, so I guess it should be able to take it.

I am now more convinced that actual building quality is the biggest issue here all right, like PizzaMan have suggested.

Yeah, and regarding using the AXP, I know man. I should probably have done something similar to that. However, I think for now I just want to get my pc up and running with as little fuss as possible. At least I get a 580 instead.
