Cheap coolers are always worth attention. In this short analysis, we focused on one such cooler. Valkyrie designates it as the Surge SL125. To avoid any misunderstanding, the word \u201ccheap\u201d refers only to the purchase price\u2014build quality on the Valkyrie Surge SL125 is very respectable. Especially considering that the MSRP of this CPU cooler sits just above thirty euros (incl. VAT).<\/p>\n

The Surge SL125 coolers belong to the lower\u2011priced offerings from the Cypriot company Valkyrie. One tower, four heatpipes, one fan. And an illuminated fan, it should be added. The entire impeller serves as a light guide for the ARGB LEDs. Two variants are available\u2014besides the usual one, there is also a white version. That white model is the one shown in the lead photo of this article, next to the base variant (with the traditional gray heatsink and black fan frame).<\/p>\n

To begin with, it\u2019s worth noting that this article does not contain any temperature measurements, as you might expect. For technical reasons, we currently cannot perform them. But we do have acoustic spectrographs, if we\u2019re talking about measurements (all the way at the end, below). These were made quite some time ago, in 2025, since which some things have changed\u2014hence why only a few results are available instead of many. The spectrographs were recorded according to the testing methodology described in this article<\/a>.<\/div>\n

* This dimension indicates the width of the heatsink together with the fan, typically toward the DIMM slots. That is, assuming the cooler is installed vertically.
\n** The distance between the shorter sides of the heatsink fins. The larger it is, the closer a symmetrical heatsink sits to the first PCIe \u00d716 slot. Or, in a horizontal orientation, potentially to the memory slots that the cooler may already cover. <\/strong><\/h6>\n

Details of the Valkyrie Surge SL125 cooler<\/h2>\n

The Surge SL125 can be described as a medium\u2011height tower design. At 155 mm tall, it fits into relatively narrower (or shorter) PC cases. It\u2019s not an especially low\u2011profile concept, but rather a mid\u2011sized one. <\/p>\n

\"\"<\/a><\/p>\n

There is one fan here (the 120 mm B12 White model with a speed range of 800\u20132150 rpm) on a single tower. This also means a narrower profile with very good RAM compatibility. Even modules with the tallest heatsinks fit into all DIMM slots next to the cooler.<\/p>\n

\"\"<\/a><\/p>\n

The tested white variant has a coating on the otherwise aluminum fins. The \u201craw\u201d (aluminum) finish is used on the variant with the fan that has a black frame. The top cover of the cooler\u2014with the light guide forming the Valkyrie logo\u2014is also black on that version. <\/p>\n

\"\"<\/a><\/p>\n

Now to the base. It comes with a pre\u2011applied layer of thermal paste in a pattern of small squares. This is just a texture that doesn\u2019t matter much. After installation, the paste spreads into a continuous layer so that no gaps remain anywhere.<\/p>\n

There are four heatpipes, and based on that, cooling performance will be optimal for mid\u2011range Intel Core Ultra 5 or AMD Ryzen 5 processors. Higher\u2011end CPUs will likely still be manageable, but probably at the cost of higher noise levels or, conversely, lower CPU clock speeds.<\/p>\n

\"\"<\/a><\/p>\n

From the more distant photo below, you can get an even better idea of what the Valkyrie Surge SL125 looks like. The fan is illuminated, with a milky impeller that diffuses light well.<\/p>\n

\"\"<\/a><\/p>\n

The backplate used to mount the cooler to the motherboard is metal. Its edges are bent to maximize compressive strength. In other words, unwanted deformation is unlikely, which promises high mounting pressure between the cooler base and the CPU\u2019s IHS.<\/p>\n

\"\"<\/a><\/p>\n

And now to the ARGB lighting the cooler features. This applies both to the impeller and to the logo on the top cover. Both elements were already mentioned above, but for illustration…<\/p>\n

What Do the Spectrographs Show?<\/h2>\n

The acoustic profile can be described as unobtrusive when it comes to any critical tones. The spectrum is balanced, with noise distribution leaning toward lower frequencies\u2014at lower overall noise levels. As fan speed increases, the sound\u2014or rather noise\u2014becomes more pronounced in the 500\u20134000 Hz band. <\/p>\n
