I'm not an experienced watercooler, but this 4 fan radiator seems to work beautifully. I had to decide on either watercooling my 2 9800gx2 cards or replacing them within the next 4 months due to overheating (they were running around 105c on full load). After installing this radiator and an Eheim 1250 pump my temps never get beyond 35c. The only con is this thing is big and you will more than likely need a custom case to install it in. Mine is on the outside of the case currently. My next system build will more than likely incorporate 2 of these radiators for GPU, CPU, northbridge, southbridge and perhaps HDD cooling on two seperate loops (I like overkill) in a custom case
The Black Ice® GTX120 brings true next generation PC Radiator technology to a higher level of performance. Using the new GTX platform, the GTX120 provides twice the liquid heat transfer surface area with a unique pre-cool/aftercool coolant flow configuration which increases heat transfer efficiency and internal system flow rates. High performance and quiet operation no longer need to be a compromise.

The first effective dual core PC radiator. High performance and quiet operation no longer need to be a compromise.
Features:
Two-pass pre-cool/aftercool front-rear dual-core flow configuration with a 30% increase in internal flow rates.
Custom MaxFin™ 25 micron Copper Splitter Fin Configuration utilizing 45% thinner fin material yielding up to 50% less pressure drop.
Unique fin configuration eliminates intra-louver accumulation of dust particles for trouble free operation.
Radically optimized 20 FPI (Fins Per Inch) fin density providing dramatically increased heat transfer surface area.
Custom low-profile 2-row 19.0 x 1.2mm MaxFlow™ tubes with twice the waterside surface area of the GTS and 60% frontal area reduction for superior low air-resistance aerodynamics and lower internal flow requirements.
Yields up to 45% more heat exchange capacity than the Black Ice® Xtreme in both Stealth or Performance modes.
Achieves Black Ice® Xtreme level performance in stealth mode (low-noise/low-airflow conditions).
M4 Threaded Screw Holes for easier mounting and greater adaptability.
Now standard G 1/4" female threaded fittings.
Max Continuous Pressure Rating of 1.7 Bars (24.7psi)
Full high-temper brass structural construction for weight reduction and superior corrosion resistance.
High performance compact radiator compatible as an upgrade to the Black Ice® Xtreme and most 120mm form factor radiators.
