Advice need on Thermaltake Bigwater VGA Block for 7800GTX

post #1 of 13
Thread Starter 
Hi Im Rob i just registered so im a newbie to this forum, this is the first forum i participate in

Before I start here are my system specs. Everything is pretty much built and ready to go, in the final process now of buying my graphics card. Either the 7800GTX 256 or 512. Depending on if I can watercool the 7800GTX 512. I notice its stock cooler occupies 2 Slots. This will not work on my board as i have a Swiftech MCX-159 Chipset cooler installed. And depending on and if the Thermaltake VGA waterblock is capable of cooling the 7800GTX 512 I might have to drop back to the 7800GTX 256. Can someone give me some advice if the Thermaltake VGA waterblock and Bigwater cooling system combinded together is capable of cooling the CPU and GPU ? I hope it can at least cool the 256Mb version of the GTX. Im open to any advice and opinions.

Well it depends on how big the waterblock is, and as long as you can hook all the hose's up or whatever then it will work.

If you're going to try to cool your cpu,gpu,and your Northbridge all with a BigWater kit, I think you're asking waay too much of that kit. You're better off using it just to cool your gpu and Northbridge combo and using like a Big Typhoon on your cpu or using the BigWater to cool the cpu and coming up with an alternative for your gpu and northbridge. (zalman comes to mind for the gpu,simple fan on the Northbridge is fine) I think you'd be disappointed if you tried to cool all 3 with the BigWater.

Im already using the best air cooling solution for my chipset the Swiftech
MCX159R Chipset cooler im only going to cool the CPU and GPU (with the added thermaltake VGA block) and need to get some advice if its sufficent. My hoses are short thus not limiting the water flow. Ive read all the reviews I can find on the thermaltake VGA waterblock but all the reviews use older less heat dissipating cards like 9800Pro etc.

I'm probably not telling you what you want to hear, but I can't go against my honest advice and that is to leave the BigWater on the cpu by itself. Not only will adding the gpu be a little much for that kit, but it leaves your video memory with 0 cooling. If it were me, I'd toss a Zalman vf700 on the video card and use the included ramsinks. The fan on the zalman will cool your video memory and I think you'll have way better results for both your video card and your cpu. The radiator on the BigWater kit I don't think can handle both the cpu and gpu if you're OCing both. Just my .02

Edit: Just looked at the vga water block and see that it does in fact cool the video ram, but I still suggest against using the big water for both. I just think that's too much heat to pull out for that kit.

Nice system,btw Whatever you decide, good luck to you and make sure to give a review! Here's another video solution to try, but if you want a sure thing, go with the zalman. It's proven itself 100 million times over.

Actually, the MAZE-4 GPU block is the best youll get...might as well go custom water cooling if youre going to cool cpu and gpu...

here is a basic set up:

dangerden TDX cpu waterblock
MAZE-4 GPU block
eheim 1240 pump
dual heatercore with 2xsunon 90cfm fans
bay res
10ft tubing

That will cool your cpu and gpu just fine, because that bigwater aint gonna cut it but if you dont want two waterblocks going, then yeah get the zalman... if youre looking for good cooling, that system there is a good beginner kit and will give you good temps.

Unless i read this post and misunderstood something, but yeah, i think thats what you were wanting to hear...

Thanks for that ! I am not going to rip out my water cooling system and throw it in the bin and get a custom built one. 1. its designed for use with my case and mouts perfectly. 2 it looks awesome. 3. many other options (ihope)

That link for the thermalright heasink for the GPU is not compatible with 7800 series what a shame it looks like its a performer judging by their xp-90 and xp-120 lineup
