No, the cap on the GPU is concave in most cases and needs to be lapped. I
have seen three different FX cards with this problem. The heat sink does
not make good contact with the cpu. A lapped copper 1u cooler on a lapped
GPU cap does a world of good. A little work but cheaper and better solution
than NV Silencer 3. The 1u cooler can be mounted to fit the four holes
around the GPU on the card.
Here is what I did.
The copper 1u cooler is a startech from gateway at $10.95.

The screws and bolts I picked up form a local hardware store (Ace Hardware)
used steel screws 2.5mm with plastic washers and the springs were from some
latched push pins from a old VGA heat sink. I placed the springs between
the two washers on the heat sink side and bolted the heat sink in place. I
used two plastic washers on the backside of the GPU. I had to cut out the
holes on the heat sink with a dremel because they were about millimeter off
center but very close. The heat sink and GPU cap were both lapped. I
placed a 80 x 80 mm fan over the heat sink using sheet metal screws through
the fins of the heat sinks on the memory and the heat sink on the GPU as
noise was not an issue. I am sure that you could use a smaller fan 40 x 40
fan for less noise. I used distilled water for clean up as it is
nonconductive. This set up cost ~ $15.00 dollars and dropped my GPU (stock
heat sink) temperatures ~15°C to 20°C from 55°C to 36°C idle the best I can
tell it ~43°C under load. BTW I have a EVGA 5900SE. The best OC is 450 Mhz
very stable at 430 Mhz. Memory will OC to 900 Mhz very stable at 880 Mhz.
I use a modified BIOS from DrInfern0.

I need a better PSU as my current unit will only supply 18 amps on the 12v
line. The GPU will most likely OC higher than 450 Mhz but the PSU will not
supply the amps necessary for my current system. Did the math and just not
enough amps for the system at the current power draw. I am looking to get a
550W PSU to correct this problem.
