Threadripper Air Coolers-Silver Arrow TR4 vs. Wraith Ripper

Author:Kyle Bennett

Date: Friday , September 28, 2018

Cooling the AMD Threadripper CPUs is not to be taken for granted. We pit the Thermalright Silver Arrow TR4 against the Cooler Master Wraith Ripper using both the Ryzen Threadripper 2990WX and 2950X processors. We show you how both these air coolers perform using Precision Boost 2 and Precision Boost Overdrive.

Silver Arrow TR4 vs Wraith Ripper

We are doing this review a bit different than how we normally do a cooler review, in a few different ways. FIrst, we have never reviewed a Threadripper CPU air cooler till today. To do a cooler review, or any review for the most part, we would all like have something to compare it to. Also, none of these coolers are for sale yet, so we do not have street prices on these. The Wraith Ripper will have a reported MSPR of $119.99, and the Silver Arrow TR4 will have an MSRP of $79.99. The Silver Arrow TR4 was delivered to us directly from Thermalright in its retail packaging. The Wraith Ripper was sampled to us by AMD with our Threadripper CPUs for review. It did not come in its retail packaging. We will be directly comparing these two coolers.

We are going to dive a lot deeper than "just" covering temperatures. We are going to look at CPU clock rates, CPU package power in watts, and of course temperatures. Threadripper CPUs support Precision Boost 2 (which is the stock performance profile), and Precision Boost Overdrive, which is a form of "automatic" overclocking. We feel that a lot of people using Threadripper CPUs are very likely going to want to use PBO. We have learned from our past reviewing of both the 2990WX and 2950X, and further looking at 2950X overclocking, there are a lot of upsides when using PBO.

We are also going to include our XSPC Raystorm custom water cooling loop into the mix as well. This is being done in order to better show just how PB2 and PBO can work on your system. That system consists of an XSPC Raystorm Neo Water Block, RX480 V3 Radiator, and D5 Photon Reservoir/Pump Combo V2.

We are using the MSI MEG X399 CREATION, and it has been excellent in our testing and overclocking. Our review of it can be found here. It sells for $500 at Newegg, and currently $560 at Amazon. For all our testing, we used the stock fan curve that is set on the CPU fan header.

The Thermalright Silver Arrow TR4 and the Cooler Master Wraith Ripper manufacturer pages can be found at the links previous, and these two coolers are very similar in construction, while being very different in how each of these look, so these two coolers make for a good comparison.


We did an unboxing of the Thermalright Silver Arrow TR4 cooler that you can see below. Thermalright is a smaller cooler company that has been on our radar for years, and has always fallen into the "no frills" category, while always coming across as being very professionally done in terms of design and manufacture.

As you might guess, the SIlver Arrow TR4 is "big" when it comes to air coolers and the box is no different. Thermalright has done an excellent job with its no-frills packaging that has always seemed to us be an effort to save money over a flashy and glossy box with lots of graphics.

Inside you will find the cooler, the fan, all the accessories you need for the primary build, as well as two sets of extra fan clips in case you want to add two additional fans to the cooler. Everything is very well secured, and much nicer than being dumped into bags as we usually find. The packaging makes everything very easy to get to when you need it. Also you will notice that there is an included screwdriver. This screwdriver is long enough to reach all the way through the cooler for install. I think many of us will find value in this. It is also magnetized in order to allow you to get the screws where you need those for install easily, but we would suggest you keep it away from any spinning hard drives.

My first thought about this fan when I took it out of the box was, "Why the hell is this thing bright orange?" Luckily, once you get it mounted inside the twin tower cooler, it is not near as noticeable. The fan is the model TY-143 case fan, which sells at Amazon for $21. It is a 600-2500 RPM fan rated up to 130CFM.

Below are some beauty shots of the naked cooler. One of the outstanding features about the Silver Arrow TR4, is that the tower is shifted sideways, so as to not intersect the first PCIe slot. We will cover this a bit more later, but it is obvious in the video thumbnail above. The base is nickel plated C1100 copper. It weighs 905 grams and has eight 6mm heatpipes. Its dimensions are 154mm wide X 103mm thick (front to back) X 163mm tall. The thermal design power dissipation is stated at being 320 watts.

As you can see, our cold plate is expertly polished to a mirror finish.
