How-To – Drinkyoghurt

My friend Supernade over at OCforums was asking for some nice cooling mods. Well, guess who had one up his sleeve. This mod will take of 3-10ºC off your temperature – I cannot verify this because the 8800GTS I am using for this mod is DEAD (not because of this mod).

Why would you want to mod a videocard’s heatsink? Modding it will result in lower temps and less noise, also added is the “cool” factor which you add to the card.

The amount of noise this mod generates purely depends on what 92 mm fan you install on it. I took a Vanessa S-Type 92 mm fan which has speed control, so you can choose between silence and performance.

Warning: I am not responsible for any damage caused by this mod, although this is a mod with a very low chance of screwing up. You might also void your warranty with this mod.

For this mod we will need:

  • 8800GTS/8800GTX with stock cooler
  • 2x Small zip ties
  • Screwdriver
  • 92 mm fan
  • Spacers (can be cardboard for the matter)

First up, remove the 4 screws that attach the shroud to the cooler:


Now take off the shroud – you can see the aluminum fins and the heatpipe.
If you look at the left side of the fins (top and bottom), you can see a few holes (bottom only 1).


Now take your 92 mm fan, spacers and zip ties and get to work. You should force the zip ties through the holes (because they are small, but if you have small and long enough zip ties, this should go easy). Do the same for the fan holes (with the same zip ties) and connect it to the heat sink firmly – two zip ties should suffice. Don’t forget to install the spacers – otherwise the fan will have a huge dead spot.


Connect the 92 mm fan to your power supply (or to your motherboard) and disable the original 8800 GTS/GTX fan as it doesn’t do much without a shroud.

Your mod is now finished, enjoy!
