To make your lifes even worse, here is another one that I did a while ago. Original fan died and I had to replace it with something so I decided to make the whole cooler bit more efficient.

Image

What you need: Arctic Silver Thermal Adhesive or something similar to work as a glue, original heat sink from GFX card and one extra heat sink from for example an old 486 CPU or chipset.

Image

Use a saw to make that extra heatsink bit smaller so it fits to the place where the original cooling fan was located. Material of the heatsink is quite soft so it is easy to saw.

Image

Glue the two pieces together. Idea here is to add more cooling surface if someone missed it. :)

Image

Original plastic fixing pins were quite small so I replaced them with couple of cable tiers to make a secure connection between the heatsink and the GPU core.

Image

Fan used here is made by BitsPower and it is 60x60 mm - 12 volt model. I used a 7 volt trick by connecting the fan's red wire to the pin that will receive 12 volts from PSU's yellow wire. Black wire from the fan was connected to the pin that will receive 5 volts from the red wire coming from the PSU.

Image

And finished product. Bigger fan, using 7 volts and larger cooling area improved both the temperatures and lowered the noise. Quite easy mod to do and highly effective if the old fan dies and you don't have the warranty any more. (or you just want to boost the performance) ;)

Mod itself should be doable the same way with most GFX cards. At least when there is this new additional power connector available. Happy Modding!

Nice work...

Do you have any over clocking improvements?

Do you have any temp results?

On my GeForce4ti4400, Image
I might be able to do that when my fans cark it. An annoying thing with those filters there is after cleaning them, you might push them into far, making a hissing noise when the fans move against the filters. As you can see by the piccies, it would be an easy job to mount either two 80cm or 70cm fans onto the card. Dammit, I got an ant in my box.... Do they cause any harm?

Hmm very nice cooler indeed An@rchy, although a bit overkill if you ask me.
