I have a Hercules 9800 non pro moded to 9800 Pro, right now i run it at 450/760 with a special cooler for the GPU (Ajigo AMD CPU cooler)
I want to buy a special VGA cooling kit but don't know which is the best solution so i can overclock more than 450/760
The canditates are:

1)Thermaltake EXTREME GIANT III

Hope u guys can help me to choose the right one.
I personaly would go for the Zalman kit.Maybe someone here uses it on a 9800 pro and can give me some feedback
Thanks in advance

PS: Sorry for my bad english

Im interested in this also..

From what i've read the VGA Silencer is the one people are using.

Btw your English is fine

Peav

VGA Silencer isn't that good frim what i heard.

the silencer is not for overclocking ... its for silent use ...

the Zalmann is better then the Tt
but passiv ... and the optional fan is a joke ... I would by the Zalman one and put 1-2 80mm fans on it
but btw ... the overclocking will not go much higher ... if not even zero %
your card runs fine ... I would stay or go for watercooling

I already bought the Zalman. It should arive this week.Anyway i know OC wouldn't go much higher if not event zero, but at least it's pasive and looks good (i will buy a new case with window ).As for watercooling, too expensive, and for that money i buy a new card X800PRO/XT
Maybe u can recommand me some good watercooling systems (for CPU and GPU)

german quality work ...
no, for real I brought this one since it was reviewed some times and got overall positive ratings ...
now for 200€ I brought a complete watercooling ...
CPU chip GPU pump watertank CU radi pipe and connectors
... 200 is quite much ... but if you compare to the effect its quite less ... since I do not need any expenseive CPU cooler anymore ... motherboard and GPU and quite ...
it really was a good buy ... I even think of upgrading it some time to latest inventions by them ...

anyway ... I just like the company profile ... they make really good work ... the give shit about cheap components or useless things ... they build solutions I want .... quite cool and high quality

only thing you need to buy is water
