Cooling the 5870

I'm going to order a new 5870 to replace my 8800GTX. Up to now, I have a single watercooling loop for both CPU and GPU. Details in sig.

Now i'm going to put the CPU in the loop on it's own for a while so I can test the new card own it's own for while using the stock cooler, just in case of any problems before removing the stock cooler.. Then I was thinking of putting the card on it's own loop, so I was wondering if the following pump/radiator combination would be ok to cool the 5870?

Swiftech MCR220 QP Stack 240mm Radiator

XSPC 200 Bay Reservoir & Pump - Clear

200 lph seems pretty low to me considering my existing Dual bay res pumps 750 lph.

Dual bay res has a lot better pump in, I'd get that and as for your rad choice, I'd personally go a Black Ice over the Swiftech but a 240 is more than enough, I run my whole rig off a 360 and thats an i7

The black ice rads that I've had in the past had a higher density of fins, so you'd need a higher pressure and faster spinning fan to get the best out of them. I'm now using rads like the XSPC ones that have a lower density of fins and they cool just as well but with lower spinning fans.

If you can fit in a thicker rad ie, 58mm of an RX rather than the 34mm of the swiftech you linked or the RS, then do it.

Swiftech out of stock.. I've got for the RS as I've not much room at the bottom of the case. I've already got a tripple
