Thermalright today introduced a variant of its Silver Arrow dual fin-stack, tower-type CPU cooler for AMD socket TR4, meant for Ryzen Threadripper processors. Capable of handling thermal loads of up to 320W, the cooler can be paired with even upcoming 250W TDP 24-core and 32-core Threadripper II models. Although bearing the same name, the Silver Arrow TR4 bears little design resemblance with the Silver Arrow ITX-R or the Silver Arrow SB-E, or even the original Silver Arrow from 2010. It's the largest cooler of this class, with an enlarged nickel-plated copper base designed to provide full coverage of the Threadripper IHS, from which eight 6 mm-thick heat pipes draw heat, with the two aluminium fin-stacks propagating along their ends.

Nested between the two fin-stacks is a 140 mm fan which takes in 4-pin PWM input, spins between 600 to 2,500 RPM, pushing 53.3 - 220.9 m³/h, with a noise output ranging between 21 - 45 dBA. With its fan in place, the Silver Arrow TR4 measures 155 mm x 103 mm x 163 mm (LxWxH). The narrow width ensures clearance for the memory slots that flank the CPU socket from either side. The fin-stack itself is offset sideways to ensure clearance for the topmost PCI-Express slot on your motherboard. You can latch on two additional fans. A syringe of Thermalright's Chill Factor III TIM comes included. The cooler tips the scales at 1,050 g. The company didn't reveal pricing.

Exposed earlier this month, Thermalright's Silver Arrow SB-E high-end CPU cooler has now become available in Europe, priced at 64.99 Euro (cheaper than it was suggested by the pre-order prices).

The Silver Arrow SB-E measures 130 x 170 x 170 mm, it weights 1124 grams, and features eight nickel-plated 6 mm copper heatpipes, two Double Ball Bearing fans - one 140 mm TY141 (900 - 1300 RPM) and one 150 mm TY150 (500 - 1100 RPM), and a universal mounting system providing support for Intel LGA 2011 / 1366 / 1156 / 1155 / 775 and AMD AM2(+) / AM3(+) / FM1 processors.

Thermalright's cooler can be found on sale here.

To finish off the week in style Thermalright announced the Silver Arrow SB-E, a new, high-end CPU cooler based on the Silver Arrow model introduced back in 2010.

The Silver Arrow SB-E features a dual tower/dual fan design and has eight (nickel-plated) 6 mm copper heatpipes (the old Arrow comes with four 8 mm pipes), a tweaked heatsink, two TY PWM fans - one 140 mm and one 150 mm (the SA packs two 140 mm spinners), and a mounting kit offering support for Intel LGA 2011 / 1366 / 1156 / 1155 / 775 and AMD AM2(+) / AM3(+) / FM1 processors.

The Silver Arrow SB-E also makes use of some more 'discrete' fan clips that won't interfere with taller memory modules. The cooler is expected to become available at the end of this month. No price tag was announced but we found it on pre-order at about $103 / 78 Euro.
