Exploring Tom’s Hardware Mastery - Cutting-Edge PC Discoveries Await

Valkyrie has only recently come across our radar as a new cooling company on the block. The company’s website states the team is comprised of more than 360 members with over 17 years of experience in cooling, so (the math of the previous stats notwithstanding) we expected a lot when the Valkyrie Vind SL125 showed up.

In the near future we’ll be looking at Valkyrie’s AIOs, but today’s review will cover the Vind SL125. Does it have what it takes to earn a spot on ourbest coolers list? We’ll have to put it through testing to find out. But first, here are the specifications from Valkyrie.

LGA 1700 Installation

Installing the Valkyrie Vind SL125n is fairly straightforward.

1. First, apply the backplate to the rear of the motherboard.

2. Next, use the included tool to secure the mounting standoffs to the backplate.

3. Place the mounting bars on top of the standoffs, and secure them with the included thumb screws.

4. Press the heatsink against the mounting bars and secure them with a screwdriver.

5. Attach the fans.

6. Connect the PWM and ARGB connections to your motherboard, and turn the computer on.

▶2x 120mm fans

I say this on almost every cooler review, but there’s more to a cooler than just the heatsink or radiator. The bundled fans have a significant impact on cooling and noise levels, as well as how the cooler looks in your case.

This picture shows a fan installed in an incorrect orientation. This was corrected prior to testing. See the section about the fans below for more details. (Image credit: Tom’s Hardware)

You’ll need to be careful when installing the fans. If you look carefully, you’ll see the blades are shaped differently. Each fan pulls in a different direction, making it easy to install the fans incorrectly. The cooler will lose 10-20% of its cooling capability if this happens. An easy way to verify if you have installed the fans in the correct orientation is by looking at the Valkyrie logos – they should be facing each other, as shown in the picture below.

The fans include RGB strips cutting across the corners of each fan, providing an illuminating accent.

LGA1700 Socket Bending

There are many factors other than the CPU cooler that can influence your cooling performance, including the case you use and the fans installed in it. A system’s motherboard can also influence this, especially if itsuffers from bending , which results in poor cooler contact with the CPU.

In order to prevent bending from impacting our cooling results, we’ve installed Thermalright’sLGA 1700 contact frame into our testing rig. If your motherboard is affected by bending, your thermal results will be worse than those shown below. Not all motherboards are affected equally by this issue. I tested Raptor Lake CPUs in two motherboards. And while one of them showed significant thermal improvements after installing Thermalright’s LGA1700 contact frame, the other motherboard showed no difference in temperatures whatsoever. Check outour review of the contact frame for more information.

Testing Methodology, and how my testing differs vs the competition

My cooler testing is designed to emulate the conditions a user would actually experience when using a computer. Some reviewers test coolers using an open bench. I do not like this method, it reduces cooling difficulty. When you use a case, the internal temperature of that case will become higher than that of the room’s ambient temperature, increasing the saturation of the cooler and overall cooling difficulty. Testing outside of a case will give an advantage to weaker coolers, especially those with fans that aren’t very strong.

Others test using a thermal heatplate. This method suffers from all the drawbacks of an open bench, but also doesn’t accurately represent cooling a CPU. A thermal plate evenly distributes a thermal load across the copper heat conduction square. The problem with this type of testing is that modern AMD Ryzen and Intel Core CPUs have most of their heat concentrated in a few hotspots – and cooling a concentrated source of heat is more difficult than cooling a source that’s spread evenly.

The last thing I do differently from some cooler testers is that I insist on using relatively new CPUs for cooler testing because people building new PCs are likely using recent CPUs. Also, thermal density is just different with newer CPUs. Products like Ryzen 3000 “Zen 2” and older 14nm Intel CPUs have lower heat density compared to modern counterparts, due to a combination of using older manufacturing processes and running at lower clock speeds. Using a weaker cooler with an older CPU can make the cooler look better performing than it actually is with current-gen silicon.

Today’s highest-end CPUs, whether Intel or AMD, are difficult to cool in intensive workloads. In the past. reaching 95 degrees Celsius or more on a desktop CPU might have been a cause for concern. But with today’s top-end CPUs, this is considered normal operation. Similar behavior has been present in laptops for years due to cooling limitations in tight spaces.

All testing is performed with a 23C ambient room temperature. Multiple thermal tests are run on each CPU to test the cooler in a variety of conditions, and acoustic measurements are taken with each result. These tests include:

1. Noise-normalized testing at low noise levels

2. “Out-of-the-box”/Default configuration thermal and acoustic testing

a. No power limits enforced

b. Because CPUs hit TJ Max in this scenario, the best way to compare cooling strength is by recording the total CPU package power consumption.

3. Thermal and acoustic testing in power-limited scenarios

a. Power limited to 175W to emulate a medium-intensity workload

b. Power limited to 125W to emulate a low-intensity workload

The thermal results included are for 10-minute testing runs. To be sure that was sufficiently long to tax the cooler, we tested both Thermalright’s Assassin X 120 R SE and DeepCool’s LT720 with a 30-minute Cinebench test with Intel’s i9-13900K for both 10 minutes and 30 minutes. The results didn’t change much at all with the longer test: The average clock speeds maintained dropped by 29 MHz on DeepCool’s LT720 and 31 MHz on Thermalright’s Assassin X 120 R SE. That’s an incredibly small 0.6% difference in clock speeds maintained, a margin of error difference that tells us that the 10-minute tests are indeed long enough to properly test the coolers.
