The Swiftech MCR320 "Quiet Power" Triple 120mm Radiator is part of the "Quiet Power" series radiators that are extreme-duty liquid-to-air heat exchangers designed to be used with triple 120mm fans and specifically engineered for high-end liquid cooled Personal Computers. They are the result of months of research and development focused on optimizing thermal performance and audible noise characteristics with low to medium airflow types of fans.

The MCR320-QP series heat exchangers have been engineered to meet today's PC industry highest thermal loads, quality standards, and low noise requirements at competitive prices.

Triple 120mm fan form factor triples the surface area available for convection of the heat into the air compared to single 120mm fan designs. The Quiet Power design yields superior performance compared to competing products in the same class.Flat brass tubes and louvered copper fins, with brass plenum chambers and frame construction, for optimum thermal conductivity.Flat frame surface provides optimum seal to the fans

• 3/8" NPT threaded hubs, for maximum compatibility with various tubing installations
• Self purging plenum chambers design: when installed upright or on its side, air cannot accumulate in the plenum chambers
• Threaded fan and case mounting holes for quick and repeated installations
• Slim design to facilitate installation and reduce bulk
• No oxidation over time (compared to aluminum radiators)
• Beautiful and durable gloss acrylic paint finish
• Competitive pricing with same class radiators (single row, 2 pass)
• Optimized for 120mm fans with low to medium output (80 CFM and below)
• Fin density optimized to reduce air noise
• Built-in plenum chamber

This radiator is a massive improvement over the mcr220 (two fans only). I was able to reduce my temps on my i7 920 by 18C and needless to say that is fantastic. i7 920 @ 4.15 with full load using prime95 for more than an hr temps never exceed 81C and that is with HT and Virtualization enabled.

I''ve had this rad for 3 years now. Ive modded my case(s) 4 times repositioning this rad, fans before, after, inside outside case ect. Through all the modding, and my Home Depot screws being too long, i wore a hole in one of the brass tubes. Little bit of epoxy, good as new...well better temps on my box with a 125 watt proc, ati 3870, than ANY other radiator out there. I gave it only a 4 because i had to tap the holes for my fans. Spacing is a bit off for those fans, but they DO FIT. Mine has dents, dings, scratches, bent fins, but ive still got 24C idle and 28 Maxed and overclocked. Pretty Nifty. MAKE SURE YOUR CASE WILL FIT, YOU WILL BE SORRY. Probably requires dremel toolage.

I have some 120mm fans in various brands, but they wont fit the screw holes on this radiator. The fans fit my case with no problem, so I think the screw holes are off on this radiator. Or the one I got was defective. The bottom set of screw holes where about 1/8" too low. I also have one of the U2UFO cases, and though its of no fault of swiftech, the horizontal spacing between fans makes it incompatible with the front 3 fan mounts on the case. I gave it a low score because the fans didn''t fit, not because it didn''t fit my case.
