A copper based VGA-HSF from a Thermal Take BLUE ORB

The system I used :

Mainboard : ABIT BX133 RAID

Processor : Celeron 1.0A (Tualatin 256Kb L2 cache)

Cooler : copper based EP5-6H11 8x8 SUNON PTB1 fan

RAM : 256mb SDRAM Corsair PC150 2-2-2

VGA : ASUS V7100 PRO OC @280/280mhz (core voltage modded from 2.05v to 2.5v ;ram voltage modded from 3.3v to 3.7v)

The story :

I wanted to put a good copper HSF on my ASUS V7100 PRO GPU to make it cool after i did the core overvolting trick

Also this time I built one using some stuff I had yet

I had a simple BLUE ORB chipset cooler and a very good Y.S.TECH 5X5 ball bearing fan

I only bought a 40X60X2mm copper plate and a 35mm diameter 5mm wide slide to do the base of my HI-TECH HSF!

The project :

First i took my BLUE ORB and I get rid of its  noisy fan,then pulled off the external fins array

After that I pset the piesces as shown in the pics :

Then i joined the parts using thermal conductive glue :

after that i worked on the fan to fit it in the modded Blue Orb, I cut the plastic bridge to the chassis fan : 

That's all, I finally got my home made copper HSF !

And the Y.S.TECH fan is more silent and give a better air-flow than the original one (probably thanks to the different rotor design).

Some Pictures :

Here you are soma particulars and the HSF on the card :

Note that the blue orb loos his tipical BLUE after i heated it on my kitchen fires to fit it on the copper circle...

Here you are some shoots of my system parameters :

This is a shoot with the clock i reached with that HSF on core and ram (a piece of Slot A K7 HSF for SDRAM)

(remember that ASUS sensing software always give higher values than the true one; the fan wasn't attached to the VGA so the fan rpm 

And this is the results with the NOT O/C ASUS V7100 PRO (200/200 mhz) :

After the O/C reached with that "Copper-Orb" (280/290 mhz) scores improved drammatically :

These aren't the best results I got from my card : with 28.32 Detonators I did 8018 and 4013 3Dmarks

in 3DMark 2000 and 2001 respectively.

Disclaimer :

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!
