Cooling compatibility for AM4, AM5 & LGA 1851

Thinking of building a new PC in South Africa? It’s a massive vibe, but one big question can stall your whole plan: will the cooler you buy today work on tomorrow's tech? Specifically, how does AM4, AM5, and the upcoming LGA 1851 liquid cooling compatibility stack up? Getting this right means you can save thousands of Rands on your next upgrade. Let’s break it down and make sure your hard-earned cash is spent wisely. 🚀

Understanding AM4 and AM5 Cooler Compatibility

For years, AMD's AM4 socket was the go-to for gamers across Mzansi. When AMD launched the powerful new AM5 platform for its Ryzen 7000 series CPUs, they did something brilliant… they kept the same cooler mounting dimensions.

This meant that almost any CPU cooler that worked on AM4 would bolt straight onto an AM5 motherboard without any issues. This backward compatibility was a huge win for builders, allowing them to carry over their existing high-performance air or liquid coolers to a brand-new platform. It simplified the upgrade path and saved gamers a ton of money that could be better spent elsewhere in their build.

This decision set a fantastic precedent for thinking about the long-term value of your components.

What We Know About Intel's Upcoming LGA 1851 Socket

Now, let's look at Team Blue. Intel is preparing its next-generation socket, LGA 1851, for their future "Arrow Lake" processors. It's set to replace the current LGA 1700 socket that houses the 12th, 13th, and 14th Gen CPUs.

So, does this mean you'll need a brand-new cooler all over again? Not so fast.

According to multiple industry reports and schematics, LGA 1851 is expected to maintain the exact same 45mm x 37.5mm mounting-hole spacing as LGA 1700. While the Integrated Heat Spreader (IHS) height might change slightly, the core mounting mechanism should remain identical. This is fantastic news for anyone planning a build or an upgrade.

TIP FOR YOU

Check The Box! 🔧

When buying a new All-In-One (AIO) liquid cooler, always double-check the product page or the box for included mounting brackets. Most modern AIOs from reputable brands like Corsair, NZXT, and Cooler Master already ship with hardware for both Intel's LGA 1700 and AMD's AM4 AM5 sockets, making them incredibly versatile.

The Final Verdict on Liquid Cooling Compatibility

Here’s where it all comes together. If you buy a quality AIO liquid cooler today, it will almost certainly come with mounting brackets for both AM5 and LGA 1700.

Since AM5 shares its mounting with AM4, and LGA 1851 is set to share its mounting with LGA 1700, you're in an excellent position. This cross-compatibility means a modern liquid cooler is one of the most future-proof components you can buy. Your investment is protected whether you stick with AMD or jump to Intel's next big thing.

This level of AM4, AM5, and LGA 1851 liquid cooling compatibility is a welcome relief for PC builders who want maximum performance without having to repurchase core components every single generation. It's a smart move for your wallet and your rig. ✨

How This Future-Proofs Your SA Gaming Budget

Let's be real, building a PC in South Africa requires careful budgeting. A decent 240mm or 360mm AIO can set you back anywhere from R1,500 to over R4,000. Knowing you won't have to buy another one for your next major CPU upgrade is a massive financial relief.

Think about what you could do with that saving. That extra cash could be the difference between a good build and a great one. It could go towards more RAM, a faster SSD, or upgrading your peripherals. That saving could net you one of the best gaming keyboards in South Africa, which can completely change how your games feel.

Perhaps you've had your eye on one of the premium, enthusiast-grade Glorious gaming keyboards known for their customisability. Or maybe you're ready to finally upgrade to a legendary Razer Gaming Keyboard for that signature clicky feel. And with the cash you've saved on the cooler, why not go all out with a full Razer keyboard with RGB backlighting to complete your setup's aesthetic? Smart planning on one component opens up possibilities for all the others.

Ready to Chill Your New Build? Whether you're on AM4, upgrading to AM5, or planning for the future, a powerful liquid cooler is a must. Explore our massive range of CPU liquid coolers and find the perfect AIO to keep your temps and your budget in check.

Many AM4 AIOs fit AM5 with adapter brackets; check manufacturer support. Some coolers need AM5 backplates or spacer kits for proper AM4 to AM5 cooler mounting.

No. LGA 1851 changes hole pattern and retention details. Use coolers listing LGA 1851 compatibility or an adapter for LGA 1851 AIO mounting.

Measure distance from socket to case panels and RAM height, consult radiator fit guides, and consider low-profile fans or top-mount radiator placement.

Some AM4 coolers use a universal backplate; others require AM5-specific backplates. Confirm with cooler specs under AM5 bracket compatibility.

Yes — custom loops are flexible. Focus on mounting hardware and CPU block contact plate compatibility for each socket before building.

Pump height and block overhang can clash with tall RAM or VRM heatsinks. Check pump clearance charts and opt for low-profile memory if needed.

Choose AIOs that advertise multi-socket support including AM4, AM5, and LGA 1851 and include adapter kits or clear mounting specs.
