Optimizing cooling HD 4850

[NIcaBoy]

Hi,
My 4850 makes a terrible noise when I play (fan in the 70%) which is really unbearable and 30% at rest since I change the motherboard because the port PCIE is quite low and therefore in my P180, it 'as much air. So without replacing the fan I wonder if replacing the thermal paste certainly low end by a Noctua and if anyone has tips to improve the cooling of this super card.

Optimize the flow of air into the case may be, Or at worst, a booster fan which brews the air near the fan the graphics card. My own is what I have to make the summer even open box on my old X1950Pro + when it is 35 ° in the piece.

Yeah that's what I do normally but then I did not see at all how to put a booster fan given the limited space available, But I also wonder if it's worth it to change the thermal paste with a much better.

What model of 4850? a base with the red PCB single slot?
I had to change the original thermal paste for the artic silver 5 on my old sapphire 4850 dual slot, and I won 2 ° C, so I think the thermal paste will not change much ... saw what you said, it must be in the air flow I think.

The thermal paste has a minimal impact in this case: yes:.

I have a antec Sonata first name that does not have a huge interior space (I still managed to accommodate my good old WC Tt Aquarius II). I ask just one 80mm fan not too noisy (kind artic-cooling 1000-2500rpm) on the back and blowing into the motherboard, just below the fan the graphic card. JI do that box open, but nothing prevents to make a cutout in the door of the box.

If it is a single slot, as long you have?

[NIcaBoy]

Enough, in fact, a single slot, which I bought a release. But when it comes to cutting a hole in the wall of my box, I did not want to sacrifice a P180 so what.

If you really want to hear less and better cooling, there is a solution, change fan. This is a little expensive but is perfect:

Zalman VF1000-LED, Its 100% copper design will provide a thermal conductivity of high-performance bonus with a design pest! Doté d’un ventilateur ultra silencieux de 80 mm, le VF1000-LED pourra sans problèmes refroidir les cartes graphiques dernière génération. With an ultra-quiet fan 80 mm, the VF1000-LED to cool without problems last generation graphics cards.

I do not really know if this noise was a little small but I did not feel or not to change fan I felt a kind Thermalright HR-03 GT or Scythe Musashi what do you think?. because the VF-1000 I already had a 8800GT therefore all take something different to change what ?
