HardwareLabs SR-1 360 Radiator Review

Technical specifications as listed by HardwareLabs:

• Two-pass u-flow configuration utilizing high-flow tubes for up to 40% increase in internal flow rates.
• Custom compressed core width to maximize airflow and enhance heat exchange.
• Optimized custom 9 FPI (Fins Per Inch) 45 micron copper fins.
• Yields up to 30% more heat exchange capacity than the Black Ice® GTX in ultra-stealth operation mode up to 2000rpm.
• Built-in 15mm deep plenum for equalized core air pressure distribution.
• M4 Threaded Screw Holes for easier mounting and greater adaptability.
• Standard G 1/4″ female threaded fittings.
• 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 III, Black Ice® GTX360 and most 3x120mm fan form factor radiators.
• Uses 100% Non-corrosive water-soluble fluxing process.
• Fully RoHS compliant.
• Full electrostatic polyurethane painting finish for uniform coating with high temperature curing for increased finish durability.
• Carbon Black Finish.
• Renowned Black Ice® quality.
• Patent Pending Design.

Core Details;

The SR-1 has a low density core with a fin count of 9 FPI (fins per inch) which was measured in numerous places on the core. The fin spacing is very even up and down the tubes. The thick tubes and low fin count should equate to a high flow / low restriction radiator which favors lower fan speeds. At 53 mm thick it classifies as a thick radiator for the round up, however it does have a thin core (33mm) relative to it’s housing thickness. That leaves 20mm of internal shroud depth which is split 13mm/7mm.

Finish and Features

The SR-1 has matte black finish and my used unit was in excellent condition, a tribute I suppose to HWLabs renowned reputation for build quality and finish. All the visible joins look perfect. The housing is solid with no flimsiness or flex on the side panels. It has some weight to it when holding it and to put it simply the SR-1 looks and feels like a high quality radiator. This sort of quality is what HWLabs industry leading standards was built upon.

There are just the 2 ports on the SR-1, inlet and outlet. There are no alternative port options nor a bleeder/fill port on the return tank. The use of M4 threads for the fan mounting screws is excellent.
