Thermalright Silver Arrow IB-E Extreme Rev. B – Dual Fan Heatsink

The new Thermalright Silver Arrow IB-E Extreme Rev. B He is heir to a long line of heatsinks that bear this name. The first Silver Arrow heatsinks hit the market the same year the processor was introduced Intel Core 2 Quad Q6600. In fact, it was one of the heatsinks most used to be able to stable overclock this processor model.

The Silver Arrow IB-E Extreme Rev. B is the second revision of the original model, which hit the market in 2012. As such, in aesthetic terms, there are not too many changes between the current version and the older one. In both cases, 140mm fans in diameter (although the older version could use 150 mm diameter fans). In both models, they continue to use two cooling towers formed by aluminum fins, together with 8 heat pipes that are 6mm in diameter and do not make direct contact with the processor IHS. The measurements The external parts remain almost the same: 163mm high, 155mm wide and 103mm deep. Only the width of the set varies, which grows 1 mm, from 154 to 155 mm today.

The Silver Arrow IB-E Extreme Rev. B uses a new anchoring system

In what has changed a dimension is in the weight of the set, which goes from 750 g of the old model, to 850 g of the new model. However, the manufacturer has not provided any data regarding the reason for this weight increase. Another aspect that is also maintained is the ability to refrigerate TDP up to 320 W.

An advantage of the new Silver Arrow IB-E Extreme is that its dimensions they do not make it protrude from the motherboard, regardless of which socket the motherboard uses. It also doesn’t interfere with mounting the graphics card. when the PCIe x16 port of the motherboard where it is to be mounted, is the closest to the socket of this.

The fans 140 mm used by the Silver Arrow IB-E Extreme are models developed for high performance. Both fans are PWM controlled and have a rotation speed of between 600 and 2,500 rpm. Having such a high rotational speed gives them a maximum airflow of an impressive 130 cfm. Although it does so at the cost of loudness, since with a maximum of 45 dBA, no it can be said that they are some silent fans. Above all, if we take into account that it uses two ball bearings in each fan.

The main difference between both models of the Silver Arrow SB-E Rev. B is their anchoring system to the motherboard, which appears to have simplified enough for the images that we have seen. Something that the clients of the brand will surely appreciate. The new anchoring system gives compatibility with all Intel sockets, from the old LGA775 to the newer LGA2066. It also provides support for the AMD AM4 socket.

Thermalright has not provided the price of this new heatsink, nor the date in which it will begin to be available for purchase.
