Silver Arrow SB-E Extreme


With the Silver Arrow SB-E Thermalright – inventor of the twin tower design – presents a specifically for highest performance designed edition of the popular Silver Arrow SB-E.

To this day, the IFX-14 has never been forgotten and is still in use in many cases. At its release in 2007, the twin tower heatsink presented a real sensation. No other cooler reached an even remotely comparable cooling capacity at that time. No wonder that other suppliers started to develop similar layouts based on the Thermalright cooler.

With the introduction of the Silver Arrow, including the innovative TY-140 fan in the summer of 2010 Thermalright was able to extend its supremacy further and put the competition once again in its place. The quiet and powerful cooler leads still leads cooler charts worldwide – no expert will impugn the superior performance of the dual-fan model.

Basically, there was absolutely no reason to present a new product. However, Thermalright would not have kept the leading position worldwide, if they did not constantly work to improve their own products. The Twin Towers flagship is particularly optimized for current multi-core processors of the latest generation, but also shows superior performance on all other platforms.

In this “Extreme” edition, by using of two particularly powerful 140 mm fans, the maximum possible cooling capacity is realized. Even popular compact water cooling systems are outclassed in terms of cooling performance by the Silver Arrow SB-E Extreme - without being significantly louder.

The main features of the cooling giant:

  • The Silver Arrow SB-E utilizes eight 6 mm high end heatpipes
  • The heatsink is optimally adapted to the fan shape
  • One TY 141 (140 mm) and one TY 150 (150 mm) fan are included
  • Both fans use a double ball bearing in the interest of the highest possible durability
  • The fan clips are designed to almost exclude "collisions" with high memory modules (heat-spreaders)
  • The universal mounting kit for all actual Intel and AMD processors ensures maximum compatibility

The twin tower design allows for a particularly large surface area and thus forms the basis for outstanding cooling performance of the SB-E. The optimized, adapted to the fan assembly design of the cooling fins of the Silver Arrow SB-E offers especially at low fan speed and little air flow a very good performance. To increase the efficiency of the cooler, the heatpipes are soldered to the base plate - an optimal transfer of heat is guaranteed. To protect against corrosion heatpipes and base are nickel-plated. The workmanship is of the highest quality.

The base of the cooler features a slightly convex shaped support surface. The design, first developed by us several years ago, has been "borrowed" from various other manufacturers since. In comparison to flat surfaces, the convex shape further optimizes the cooling performance - especially on Intel systems.

The powerful "Extreme" fans provide at the maximum speed of 2,500 rpm an air flow capacity of up to 220 m³/h - per fan (!). With a total capacity of up to 440 m³/h, the Silver Arrow SB-E Extreme outperforms all cooler combinations we are aware of. Compared to the standard-version, the total cooling capacity has been improved considerably; an advantage especially for overclocked PC-systems.

Naturally, such a fan capacity will result in a corresponding noise level – but even at 45 dB(A) - the maximum noise level according to the manufacturer – the sound volume is not considerably higher than that produced by powerful compact water cooling systems with identical settings. The two double-ball bearing fans are PWM controlled and thus can automatically adapt to the individual circumstances. The extremely wide control range between about 600 and 2,500 rpm ensures the audible sound generated by the fans will be quite acceptable with max. 21 dB(a) during standard operation.

The Silver Arrow SB-E Extreme is multiplatform compatible and comes with mounting material for all common processors. Owner of Intel LGA 775/1366/1155/1156/2011/1150 motherboards can use the cooler as well as users of AMD AM2/AM2+/AM3/AM3+/FM1/FM2.

Due to the high power consumption of up to 7.2 watts, the two fans should be connected directly to the PC power supply by a special adapter cable (the PWM control is retained).
