I wanted to put a good copper HSF on my ASUS V7700 GPU to improve stability after the mod @TI and the consequent core O/C
Also this time I built one using some stuff I had yet and in a sipler way than I did with the V7100 PRO
I had a simple BLUE ORB chipset cooler and a very good Y.S.TECH 5X5 ball bearing fan
I only bought a 50X60X3mm copper plate to do the base of my HI-TECH HSF!
This time I only decided to replace the ugly an thin alluminium base with a better and wider copper one
I did the base shape on the copper 60x50x3mm base :
I think it is better give it a shiny face.....
As you can see the cooper based is larger than the original lapped one,the chipset will be completey covered...
And now let's get rid of that little base!
The Blue Orb array need to be lapped before join it to the copper base :
After that I joined the parts using thermal compound (and engine sealant as glue on the array edges) as I did with the Tualatin recovering:
The alluminium coin was reintroduced in the centre to obtain a fan-support (note how dirt is the original base under the coin!) :
Then i used the same kind of fan i used on the other mod , note the wings differences :
Here you are the final results, the NEW COPPER ORB on the ASUS V7700 card :
After this mod my V7700 looks very cool with that nice copper orb ,and temperatures were so low that i reached for the first
time the frequencies of 275/430 Mhz with stability and the max GPU Temperature was only 49°C after a Q3A session!
These results where reached on my system, and I can't guarantee this kind of HSF works as good on a other HOT GPU.....
Anyway it would be an interesting bet running a GF3 or GF4 and comparing the T °C and the overclockability grewn
If you are tired of your blue orb noise or lacking performance try to give him a copper base and you'll have a better cooler!
have fun!
