6800 cooling mod

sbohdan · May 13th, 2006

I just made a little cooling mod and thought would share it. actually this 6800 card is something I bought to get by till I get the 7900GT :)
the main reason for this mod was to lower the whinning sound of the original cooler and to get better cooling (there are no mem sinks on the card at all :( and the original GPU cooler is redicolusly small and inefficient. the whole mod cost me nothing (I used an old P4 heatsink for the memory (had to chopp it up) and an old unidentified cooler (booth were bought by me long time ago in a used comp. parts store for pennies, same goes for the fan) that was laying around. so here are the pics:

the ingredients

the P4 heatsink before it was cut-up

the two contestants

the drilling

the screwheads for fitting the sink didn't quite fit, so I had to make some space

comparison

and a couple of pics of the ready product:

the whinning sound is gone now (the fan is working on 9V instead of 12V and is bigger)
the temps dropped 7C @ idle & 10C @ full load (48C from 58C), so considering that I didn't even try hard (no money or too much work 8) ) I'm happy with the results. next I will change the other noise maker (the north bridge cooler) to a swiftech MCX-159CU to lower my overheating NB and to cancel the last source of excessive noise :P

what do you use to attach the ram sinks?

He probably used thermal tape. He might have used arctic alumina, or whatever that thermal epoxy is. Another method he might have used is the glue in four corners with as5 in the middle.

Lets see if I hit the bird.

you pretty much covered all the methods ty

sweet mod man! does it increase overclockability at all?

:oops: Forgot to compliment your mod! Looks really awesome. With all those fins and metal blocks everywhere. Like cooling beast. You definately gained a good 100 mhz there.

Nice work man! The ramsinks are some of the biggest I've seen.... How did you attatch the ramsinks?

sbohdan · May 14th, 2006

thanks all. those of you that saw my other mods know that this one was pretty standard for me

as for the ramsinks: I attached them with a thermal tape. OC ability is increased somewhat but is limited because of the lame (2.8ns=700Mhz) ram which is allready @ the rated speed :? even like that I was able to have it @ 760Mhz stable and with much lower temps (before the ram was boiling hot). with increased voltage I would be able to give it more juice but I don't want to solder on this card since when I get the 7900GT I wanna return it to it's original state and sell it.

BTW ranger: you have the CPU that I wanted but wasn't compatible with my mobo :( Nice OC :P
