Thermalright Silver Arrow IB-E – Test and Review

According to my personal experience and the official web page , Thermalright Silver Arrow series already includes five models designed as massive twin tower coolers with very serious dimensions, offering extremely high performance, outstanding appearance and cooled by at least two 140mm fans:

  1. Thermalright Silver Arrow – the first model announced back in 2010 with current status – End of Life
  2. Thermalright Silver Arrow SB-E – the second model announced back in 2012 with current status – End of Life
  3. Thermalright Silver Arrow SB-E Extreme – the third model announced back in 2012 with current status – End of Life
  4. Thermalright Silver Arrow IB-E – the fourth model announced in 2014, which is the actual silent version
  5. Thermalright Silver Arrow IB-E Extreme – the fifth model announced in 2014, which is the actual performance version

For this test and review I am going to check what Thermalright Silver Arrow IB-E has to offer and how it will handle my processor. And if I have to compare it to Thermalright Silver Arrow SB-E Extreme, which I already tested two months ago, I expect to see some serious improvement! Whether this happens, we will find out a bit later.


Thermalright Silver Arrow IB-E was provided to me for doing a test and review in the pretty standard for the brand, very big carton box made as usual of recycled paper with just the company name on the front side of the package. Of course, any technical specification, any additional pictures or details regarding the product are completely missing on any side of the box, apart from the model name on the side of the package, but again this is a cooler made for all those users who know exactly what they need and what they will achieve using this product.

Pretty simple, stylish and ECO friendly package to be honest, but let’s check what’s inside.


After I opened the Thermalright Silver Arrow IB-E′s package, first thing to notice was the typical for the series pretty thick installation manual, which I strongly advice to be used before and while installing the cooler. Beneath the installation manual, inside a Styrofoam bed there is the heatsink itself, carefully packed inside a nylon bag and holding a small white box between the two towers with all of the additional accessories inside. As usual both of the fans were placed in additional compartments on both sides of the heatsink.


So first things first and let’s check what is inside the white box holding the additional accessories.

Before I describe all of the additional accessories provided with Thermalright Silver Arrow IB-E, I want to point out that all of the them were packed in separate nylon bags so nothing is lost and to use them, the users have to cut the bags.

After I took all of the accessories from their packages and carefully arranged them for taking some pictures this is the view I got.


The standard package content:

  1. Painted in black metal backplate needed for both Intel and AMD sockets
  2. A semi-transparent white isolation pad for the backplate
  3. Silver metal square frontplate needed for both Intel and AMD sockets
  4. Silver metal plate made to hold the cooler attached to the front plate needed for both Intel and AMD sockets
  5. 4 x Nut screws with rubber dumpers
  6. 4 x LGA 2011 type B screw pillars
  7. 5 x M3 L10 screws (one is spare)
  8. 7 x M3 L6 screws (one is spare)
  9. 6 x fan clips for installing up to 3 fans
  10. 4 x Intel backplate washers
  11. 4 x AMD backplate washers
  12. 8 x anti-vibration pads for installing on 2 fans
  13. Backplate cap
  14. A small wrench
  15. 1 x Y-splitter cable for powering up to 2 PWM fans directly from a CPU fan header on the motherboard
  16. Thermal compound
  17. 2 x TY-141 fans

Pretty extensive package content to be honest but I believe it is time to check out the cooler structure already…

Ok enough for the package, lets check the cooler itself…

Thermalright Silver Arrow IB-E as every other modern cooler on the market is made of three major components which I am going to describe one by one in this article and they are: the two-tower heatsink, the cooling fans and the mounting kit.

As usual let’s start with the heatsink.


Thermalright Silver Arrow IB-E offers a heatsink with dimensions of 154mm (L) x 103mm (W) x 163mm (H) mm and radiator weight of 750 grams featuring a nickel plated copper contact plate, 8 x Ø6mm copper heatpipes with nickel coating and without direct contact with the processor, and of course aluminum fins grouped together forming two towers.

As usual let’s start with the contact plate since it has the most important role.


Thermalright Silver Arrow IB-E features a perfectly milled, with dimensions of 40 x 53 mm contact plate made of C1100 pure copper with nickel coating holding in line the 8 x nickel plated Ø6mm copper heatpipes made to pass through, transferring and dispersing the heat from the central processor unit to the aluminum fins. With these dimensions the contact plate is suitable to be used with all sockets on the market and keep every modern processor cool and running.


All of the heatpipes offer a nice visual finish including additional caps on the top of the fins stacks made for boosting the overall appearance of the cooler.


And here I want to point out that all 8 heatpipes are perfectly symmetrical to the contact plate and non-symmetrical to the two towers. 

As one of the newest and the best coolers in the company portfolio with outstanding high build quality of the heatsink this is guaranteed by a small original company sticker on the top side of the contact plate, which can be seen between the two towers.


Now let’s pay some attention to the next part of the heatsink, which is actually the surface made for dispersing the heat, aka the fin stacks.

Thermalright Silver Arrow IB-E offers a pretty unique two-tower radiator design with dimensions of 154(L) x 39(W) x 106(H) mm and 45 absolutely identical nickel coated and very shiny aluminum fins each with 2mm fin gap. As usual when seen from the top the two fin stacks have a shape of two arrow fetches facing each other, which is the very typical design for the series.

And here is the most interesting thing regarding the cooler. The heatpipes are passing through the fins stacks in a non-symmetrical way so the heatsink can provide wider structure with well balanced fin surface heat dispersing and boosting the overall performance and compatibility. Thus the cooler covers the top part of the motherboard if it is installed vertically or the VRM heatsinks if it is installed horizontally. With this the cooler provide a bit bigger fin stack surface and uses the space over the motherboard which is empty of tall components. Pretty nice idea, which will lead to same or better performance as the older Arrow models but working with much slower fans. And by saying fans let’s talk about them.

Cooling fans:


The standard Thermalright Silver Arrow IB-E package offers two TY-141 fans with light brown round frames made to be installed on a 140mm case fan slot or cpu cooler heatsink and painted in grey propellers with 7 very wide with not very sharp angle blades with dimensions of 152 mm (L) x 140 mm (H) x 26.5 mm (W) and weight of 170 grams each. A pretty standard Thermalright fans design I can say. Both of the fans are working at 900 – 1300 revolutions per minute range providing airflow level range of 28.32 – 73.64 CFM at noise level range of 21~25dBA.


And as usual the quality and the origin of the fans is guaranteed by a small sticker on the back of the motor.

Before I continue with the tests I will have to install the fans and prepare the cooler for installing on the motherboard.


To install the fans I should first install the 8 rubber pads added to the additional accessories made to provide nice and soft contact between the aluminum fin stacks and the plastic fans. These pads are meant to reduce the vibrations of the fans and overall reduce the noise level when the fans are working. Of course for installing a third fan additional 4 rubber pads will be required and they are not included in the standard package.

With the pads added, now let’s install the fans to the heatsink and continue with the article…

And this is what the cooler looks like with the fans installed.

After some calculations, I believe every single fan consumes up to 2.4W power, which can allow both of the fans to be PWM powered and regulated directly from the motherboard CPU fan header via an Y-PWM splitter provided in the standard package content.


All parts assembled together formed a very massive and really beautiful CPU cooler which should require very reliable and massive mounting kit. And I believe I am finally ready to install the cooler on the motherboard and do some testing…

Mounting kit:

After I spent some time describint the heatsink and later the fans I believe it is about time to check the mounting kit.

  1. Intel sockets: LGA 775/1150/1155/1156/1366/2011
  2. AMD sockets: AM2/AM2+/AM3/AM3+/FM1/FM2

All of the Intel and AMD sockets require the same frontplate, backplate and holding for the cooler plate. The only difference are the screws and bolts needed for connecting the brackets.

Of course, for doing the tests I will use the AMD brackets and these are the parts needed so the cooler can be installed on the motherboard:


As always, there are a lot of parts which should be assembled together and installed on the motherboard:

First thing to do as always is to open the installation manual, read the instructions carefully and pick up the right accessories for the actual socket…

And after that to prepare the backplate before attaching it to the motherboard.

All parts related to the backplate
All parts assembled

With the backplate ready it is time to install it on the motherboard:


With the backplate attached to the motherboard next step is to add the front metal plate, which will hold the cooler…


And this is what the heatsink looks like installed the motherboard:

Seen from the front
Seen from the side
IMG_8982 IMG_8983

I am pretty sure that you have already noticed how the heatsink leaves the motherboard top edge on the top side. As I’ve said earlier a bit wider heatsink to use the empty of tall components space. Good idea…

The complete cooler installed on the motherboard…


As usual for the Thermalright Silver Arrow series the RAM modules, VRM heatsinks and basically everything around the socket is beneath the cooler. And I believe that the engineers from the company thought about this and made the fan between the towers to go a bit lower so it can provide a steady airflow beneath the aluminum stacks too and keep the surrounding components cool too.

Before I start testing I think it will be nice to check what system I will use for doing the tests:

Test rig:

CPU: AMD Vishera FX-8350

  1. At standard frequency 4.020 MHz (at 1.356V)
  2. At low overclock frequency of 4.220 MHz  at 1.380V)
  3. At medium overclock frequency of 4.420 MHz (at 1.416V)
  4. At high overclock frequency of 4.720 GHz (at 1.440V)

Motherboard: GigaByte 990FXA-UD3

Video card: 2 x Gigabyte GV-R927XOC-2GD

Memory: 2 x 4GB Geil Black Dragon 1866 MHz

Hard drive: Kingston SSD SV100S264G

Case: SilverStone Raven RV-03

Power supply: Antec HCP-750W

Cooler: Thermalright Silver Arrow IB-E

Thermal paste: Gelid GC-Supreme

Fan mounted:

For this test and review I am going to use the standard TY-141 fans working at 1300 revolutions per minute providing airflow level of 73.64 CFM at noise level of 25dBA.

The tests were conducted in a closed system with:

  1. 2 x SilverStone AP181 – 180mm fans on the bottom panel putting fresh air in and spinning at about 1200 rpm
  2. 120mm fan on the top panel taking hot air out and spinning at about 1000 rpm.
  3. Room temperature of about 18 degrees.

Both of the SilverStone AP181 – 180mm fans were connected together to the chassis 1 connector and were rotating at maximum speed.

Testing procedure:

I will install Thermalright Silver Arrow IB-E and do stress tests at standard frequency of 4.020 GHz (at 1.356V), at low overclock frequency of 4.220 GHz (at 1.380V),  at medium overclock frequency of 4.420 GHz (at 1.416V), and at high overclock frequency of 4.720 GHz (at 1.440V) first using only one of the fans installed between the two towers of the cooler and later stress tests at standard frequency of 4.020 GHz (at 1.356V), at low overclock frequency of 4.220 GHz (at 1.380V),  at medium overclock frequency of 4.420 GHz (at 1.416V), and at high overclock frequency of 4.720 GHz (at 1.440V) with both fans installed on the cooler working at maximum speed.

And this is what the CPU cooler looks like when installed inside the case and ready for testing..

And the fan speed during the tests:

Results RPM

With the test results added to the article it is about time to share my conclusions.

1. Thermalright Silver Arrow IB-E performance:

After a few hours of unpacking the cooler and all of the additional accessories needed for normal operation, arranging them for taking pictures, installing and finally after I’ve finished testing I can say that Thermalright Silver Arrow IB-E is one really interesting product offering an amazing performance/noise level balance.

The thing which made me smile is the really huge heatsink offering a very massive non-symmetrical design, obviously made for extreme cooling, combined with very quiet and well performing fans. The heatsink itself is made a bit wider than the older models from the series and require some additional space around the sockets which for most of the motherboards on the market is empty of tall components. With the wider heatsink improvement the cooler is suitable to be used even with the hottest processors available on the market working at default, overclocked or extremely overclocked frequencies. It will definitely handle to keep them working cool and quiet.

And here I want to point out that some of the extreme motherboards on the market offers a tall VRM heatsinks and may have compatibility issues when installing the cooler. Apart from that, RAM modules with taller heat spreaders will definitely overlap with the front fan, which can be moved to the back side of the cooler

2. Thermalright Silver Arrow IB-E appearance:

Thermalright Silver Arrow IB-E is a product featuring even more massive and reliable looking cooler design than the older models from the series with a stylish and very, very shiny heatsink, combined with two 140mm fans in the light brown/grey colour scheme, which to be honest isn’t really my first choice for a colour scheme but when the cooler is installed inside the system it definitely looks impressive.

According to my review, I think that Thermalright Silver Arrow IB-E deserves the following reward:


Official price (MSRP) for Thermalright Silver Arrow IB-E: 64.99 euro

Official warranty: 24 months

I thank Thermalright for the test sample.

    Unfortunately I can’t overclock higher than 4.7GHz per core. There is no doubt the cooler will handle but I doubt the motherboard VRMs will. Apart from that I require voltage over 1.52V for 4.8 and the VRMs are overheating even with additional cooling.

    Soon there will be a comparison between ThermalRight Silver Arrow IB-E vs New Noctua NH-D14, just waiting for the NH-D14 to arrive 🙂

    It will be a serious battle.

    I wish you did a bit more overclock as there is obviously so much headroom. The true high end. I wish we see a lot of reviews against Phanteks PH-TC14PE.

    So many pros for this cooler: awesome color, excellent performance, very low noise levels and so on. If I decide to change my (212 Evo), this one will be in the list to choose from 🙂
