Hello,

I have a problem with my graphics card heating up too high. I was just playing Callofduty 4 Demo and
I was playing for about 20minutes and I exited and see my Graphics card temperature @ 85C!! Thats a
little too hot for me and I was just thinking would water cooling help me out in this situation? I know that
when Callofduty 4 comes out I'm gonna be playing it for more than 20min at a time and it might heat up
to around 90C if I play for a few hours strait (which I will =p) that will definately affect gameplay. Right
now I have a custom fan on my card which my card is A X1900XTX , it's a year old but its still at the top
of the charts performance wise. Also I believe my card also idles to high, it's usually idles @ 50C. I was
wondering if water cooling will greatly reduce this and what setup should I buy if so? And if it will only
reduce the temperature by like 5C then it's probably not worth it. But if it can keep my card under 70C
under load then I might get it. So please just post your ideas and a setup (preferable cheap setup) that
I can get so I can play cod4 for hours strait!!


Thanks!!

Yes water cooling will drop your significantly, probably as much as 30*C if you get a good setup. The the temperature drop comes with a price, you looking at, at least a 200$ price tag.
Swiftec has a good CPU+VGA+north bridge combo selling for slightly less then 300$.
If you want to drop temps on a budget your best bet would be an after market air cooler from artic cooling or something similar.
Be warned however, this voids you warrenty and do either setup wrong and you cook your card.

I'll use what I plan on doing for my water cooling setup.
Take this as an example, for an overclocked HD2900XT
http://www.techpower...terblock/5.html
As you can see, the overclocked card will drop from 83*C on stock all the way down to 48*C, a significant drop. Considering I'm happy if my card runs below 70*C.
Keep in mind though, on this setup the VGA cooler was the only conponent being cooled in the loop. If you are cooling a overclock quad and a VGA I recommend a 2 rads.

Hello,

Thanks for your reply. Anyways I am just going to cool my VGA card. And how much would a water cooling
system be for just my VGA card and not like everything in my case?

There are a huge veriety of things to look at, I'll break it down a bit, everything here is a rough estimate.
Pump - 70$
Tubing - 10$
Resevoir - 20$
Rad - 50-120$ (this is were I'd invest as much as possible, as it ultimately determines your cooling performance).
VGA water block - 60$
Fans - 10-20$ (depends how quite you want it, some rads even come with the fans).
Water additive -5$
Hose clamps - 5$
RAM sinks - 10$

Pretty sure I have listed everything here. As you can see, your looking at a significant investment if you wish to water cool.

Yes there are kits, but they include other things such as a CPU cooler, I have yet to see a kit with only a VGA cooler.

You could get this and then add another single rad and the GPU cooler.
I don't think this rad alone will be enough to handle a CPU and GPU which is why I suggest getting another Rad on top of what it offered (two rads in a single loop).
But now your looking at 300$, a significant amount of money.

Do you believe that this set would work?

It might work ok, but nothing great. It's fanless so the heat wouldn't be dissipate as quickly, also keep in mind the pump is intergraded into the rad so if it goes you have to deal with Zalman for a replacement which may be a pain. I'd look around on the web for some in depth reviews, but I'm a little short on time right now. If I have a chance tomorrow I could.

It's got fans but I'm not sure if it has VGA cooling.

As the saying goes you get what you pay for it. It's a single fan rad, not nearly enough for a CPU and VGA card.

Hmm ok then when you have enough time can you just get me links to seperate pieces of a water cooling system that I can use to only cool my VGA card? Thanks for your time!
