Nvidia cooling. TOO HOT? TOO NOISY?

(Link to pictues above)

so this cards auto speed control doesn't work and the fan continuously blasts away until riva tuner slows it down when windows starts up. the noise bothers me but what bothers me most is the fact that even if i turn the fan up to full (including the ones in my case) the card excedeeds 100C when running intensive applications. So i got the heatsink from a dead xbox 360 (paid 8 pounds for the dead xbox) and drilled holes in it to match the heatsink mounting holes. The heatsink was slightly too large so i had to bend the heatpipe back. The cooling with that left the temps about the same so i decided to add some fans to it.

furmark extreme burn in stock heatsink : 10 mins before test stopped because it exceeded 100C

furmark extreme burn in ghetto heatsink : ran for 12 hours before i stopped it because i got bored it reached a max 0f 76C

the specs for the rig is in my signature ( INTEL GAMING RIG ).

That looks like a 10+yr old graphics card...and really? Home improvement screws... You bent the heatpipe that bad probably means the contact on the chip is horrible and the seal broke too. You probably also punctured the heatpipe, basically rendering it useless...

Buy a real cooler for it. Even a block of aluminum fins with tapped threads with the right size screws would do the trick..

the heatpipe stilll functions correctly. You can feel the heat being transferred and there are no holes. The contact is solid since the graphicscard has lowered in temps. The graphics card still plays the games i want it to play and i don't mind .

Ghetto rigging can work, but two questions:

1. What kind of thermal paste are you using?
2. Is the fan header 3-pin or a 4-pin PWM? If it's 3 pin that could explain the loudness that isn't throttled down until RivaTuner kicks in

The fan header is the average 2 pin on nearly all graphics card. im pretty sure 4pin pwm only applies to cpu fans? Im using IC Diamond 7 for both the stock and the ghetto.( i reapplied paste for the stock heatsink first thinking that was the problem)on the ghetto heatsink i am using a free 3 pin header on the mobo with a fan silencer in between to slow the fan down.
