With the Silver Arrow IB-E Thermalright presents a revised version of one of the most powerful twin tower coolers in the world, which has been modified to meet current customer requirements. True to the motto "innovated - not imitated" the current flagship of the cooler series makes use of innovative new features to improve an already excellent product even further.

The main novelty of the Silver Arrow IB-E is the new design of the heatsink. To ensure the best possible compatibility with motherboards and cases, the aluminum fins are now staggered. Once more Thermalright proves that they are happy to respond to the suggestions of the fan community. The revised design ensures that the top PCIe slot on ATX motherboards is no longer blocked by the heatsink - a frequent criticism of testers and users when using twin tower design coolers.

On the other side the heat sink does not protrude beyond standard ATX motherboards, which also excludes incompatibilities with fans mounted under the top cover or power supplies installed at the top of the case. The higher distance from the aluminum fins to the copper base prevents collisions of fan and high-rising heat sinks of RAM-modules. And finally Thermalright was able to reduce the total height of the cooler by about 5 mm, by means of reducing the height of the heat sink and the use of two TY- 141 (140 mm) fans. This means that the cooler can also be used in Midi-towers, for which the predecessor was simply too high.

The twin tower design allows for a particularly large surface area and thus forms the basis for outstanding cooling performance of the IB-E. Especially at low fan speeds and a low air flow rate the Silver Arrow offers an outstanding cooling 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 heatsink sports eight 6 mm thick sintered high-end heat pipes in order to dissipate the processor heat quickly and effectively. In connection with the two TY 141 fans all current processors can be effectively cooled.

The ball-bearing fans are temperature controlled (PWM) - the speed is depending on the CPU temperature between 900-1,300 rpm. The use of two fans means that both fans can work in most cases almost idle. By using two fans both TY-141 will be working at idling speeds most of the time. At the minimum speed of 900 rpm, the TY-141 reach 28.3 CFM air flow, at the maximum speed of 1,300 rpm the TY 141 each pump an impressive 73.6 CFM through the heatsink. A Y-cable is supplied to regulate both fans over a single PWM fan connector of the motherboard.

To guarantee a most silent operation, the TY-141 uses seven special "torpedo" style blades. In conjunction with the optimized wings and the streamlined frame design, this allows for a very effective and also particularly quiet air flow. Two pairs of fan clips for fans with 120mm mounting holes are included.

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 Silver Arrow SB-E is, of course, multiplatform compatible and comes with mounting material for all common processors. Owner of Intel LGA 775/1366/1155/1156/2011/1150/2011-3/1151* motherboards can use the cooler as well as users of AMD AM2/AM2+/AM3/AM3+/FM1/FM2/FM2+.

*We strongly recommend to use our specially designed 1151 Support Spacer when mounting the cooler on LGA11 “Skylake” CPUs. Please send us an email, to receive them for free.
