9800GX2 on a single 120MM rad....

[CanadaRox]

You could always get a second pump and res and split the loops. The external and 9800GX2 on one loop, and the internal for the CPU alone, and then the NB could be put on either loop really, not a huge heat dump from it.. That should keep it all nice and cool, without even the need to add another res.

But this would depend on your current temps.

How about a triple rad instead of one of the external double and tie the gpu into that?

I know your not keen on the idea of a rebuild and more money though. I guess you can just try the single and take it from there--you'll probably be pleasantly surprised anyway cw stock cooler- that GPU is hotter than a goldminers lunchbox.

pats his XFX 8800 GT its times like this im glad i bought it runs cool runs well and plays BattleStar Galactica HD superbly!!!!

[Cptn Vortex]

Yeah....knowing me I will find a way to re-build....I know.... Luckily this time, I installed a T-line at the bottom of my loop, so as to drain it easily. Thinking ahead!

[Dashock]

A T-line maybe i should think into that eh what do yu think ?

[Cptn Vortex]

It's easy enough to add one. After draining my loop about 5 times I realised it would be handy....

What about spending the big bucks for a Thermochill PA 120.1? They're pricy, but supposedly well worth the extra coin performance wise.

I just ordered up one to add to the Cosmos S (bottom front fan intake). I'll let you know once I get it installed if it made much of a difference added to the same loop as a MCR320 Push/Pull config.

It looks like you might be able to replace both rads with triples, that would surely do it.

[Cptn Vortex]

..... not about to spend the cash on replacing both my Rads with tripples....already have one PA120.2...costs a pretty penny itself. I will try with the single 120mm RAD, and if not good enough, then I will make room for a second. I will run 2 seperate loops.

Is that GX2 really noiser than those Ultras at 1500rpm? Damn, that's terrible.

Swiftech states that their single rad should be able to dissipate 100W at a 10 degree temp air-water delta, using a 1200rpm/47cfm fan. Since your Ultras are quite a bit more powerful than that, so even more heat could be handled with such a fan (probably over 150W, to extrapolate from the Swiftech graphs). Now, if you use a 20 degree delta instead of 10, you can double the heat capacity. Say 200W, to be very conservative, which is about the level of your card at max load.

Now, I routinely see people reporting temps in the 50's with that card under water, so with the extra 10 degrees in air-water delta, you could reasonably expect temps in the 60's, even at max load.

Anyways, that's my 2c.
