A cooler can match your processor socket and still stop the side panel from closing. Peerless Assassin 120H-A Dark makes that distinction worth checking before you order: this is a substantial dual-tower design, rather than a small replacement for a stock cooler. Its dark finish may suit your build, but the installed dimensions, memory position and purchase route decide whether it belongs there. Measure the assembly you will actually use instead of relying on a photograph of an empty motherboard.
Quick Answer
The cooler is listed at 159mm high with its fan, with six 6mm heatpipes and support for AM4, AM5 and several Intel sockets. There is no verified South African price for this exact model here. A Gamdias BOREAS E1 410 LITE was R499 and in stock on 1 October 2026, giving a budget reference rather than a performance match.
📏 Measure above the processor and memory
Start with the case manufacturer's CPU-cooler height limit, then compare it with the complete 159mm assembly. A figure for the heatsink without its fan answers a different question. Keep the side panel and any internal protrusions in mind when assessing a close fit; a listed limit equal to the cooler height leaves little room for an installation that differs from the standard arrangement.
Tall memory deserves a separate check because the fan and DIMMs share nearby space. If you need to raise a fan to clear the memory, the installed height can increase. Do not treat that adjustment as free clearance. Lay out the motherboard, memory and cooler positions together before committing to the case, particularly if you are reusing a compact enclosure.

🔧 Match the socket and mounting parts
The socket list includes AMD AM4 and AM5, plus Intel LGA115X, LGA1200, LGA1700 and LGA1851. That establishes the listed mounting compatibility; it does not prove the cooler is appropriate for every processor workload or case. Confirm that the seller supplies the mounting kit for your chosen socket, then use those instructions rather than parts left over from an older installation.
Six heatpipes describe the construction, not a guaranteed temperature under your workload. A sustained rendering job and a short game session can place different demands on the same system. Choose the cooler alongside the processor's operating limits, case ventilation and your noise preferences. Do not turn a material specification into an unsupported promise about degrees or frame rates.
🧾 Keep the purchase and warranty route clear
The exact product page states a three-year warranty. Retain the invoice and serial number, and establish who handles a claim before you pay. Thermalright's terms exclude improper installation and unapproved brackets, and they distinguish authorised purchases from unauthorised parallel imports. A longer warranty mentioned for another family is not a reason to assume this model gains extra years.
For a rand budget, compare CPU coolers with the available air cooler range after checking fit. The R499 snapshot is useful for setting a starting budget, but availability can change and the alternative has different specifications. Ask for the exact model, full delivered cost and warranty route on a current quote; do not price an announced cooler by converting an unrelated overseas listing.
Frequently Asked Questions
How tall is this cooler with its fan?
The listed height with fan is 159mm. Compare that with the case limit and leave extra room if the fan must move above tall memory.
Which AMD sockets are listed?
Thermalright lists AM4 and AM5. Use the supplied mounting parts and follow the instructions for your exact socket.
Is LGA1851 included in the Intel list?
Yes. The product also lists LGA115X, LGA1200 and LGA1700. A socket match still does not establish case clearance.
Does black paint establish better cooling?
No. Colour does not provide a measured temperature advantage. Judge fit, workload, airflow and tested performance separately.
What warranty does the exact product list?
Its product page states three years. Keep your invoice and check the seller route before paying; broader family terms do not extend this model automatically.
What local cooler price gives a starting reference?
Gamdias BOREAS E1 410 LITE was R499 and in stock on 1 October 2026. That is an alternative budget reference, not a price for this Thermalright.
