AMD's AM4 socket will not be compatible with old CPU coolers

Published: 19th December 2016 | Source: OC3D | Author: Mark Campbell

It looks like old AM3+ compatible CPU coolers will not fit on AMD's upcoming AM4 CPU socket, making it difficult to use older CPU coolers on the new platform.

Ever since AMD's AM4 CPU socket was announced there has been a huge debate over whether or not this new platform will support existing AMD-compatible CPU coolers, using AMD AM2 compatible mounting solutions or newer. AMD has used the same cooler mounting solution since their AM2 socket, which dates back to 2006, leaving many to assume that things would remain unchanged with AM4.

Since then we have heard many reports regarding AMD's AM4 socket, though it now seems that AMD's AM4 socket will indeed be using a new mounting solution, with the new socket using a 90mm x 54mm mounting solution instead of AMD's traditional AM3+ 96mm x 48mm mounting solution.

AM2/3/3+ FM2/2+	96mm	48mm
AM4	90mm	54mm

AMD's AM4 socket will not be compatible with old CPU coolers

Noctua has already confirmed that their existing CPU coolers will be AM4 compatible, with plans to ship a free AM4 mounting kit to everyone who uses a Noctua CPU cooler that is under 10-years-old, with the exception of their D0 series and their NH-L9i series.

This report from Noctua alone did not confirm that AMD was using a new mounting solution, but later images appeared of the CPU socket and now pictures of AMD's AM4 mounting plate have surfaced, confirming that the new socket will indeed use different mounting holes.

Below we have pictured two Alphacool Eisbaer/Be Quiet Silent Loop mounting brackets, with the older AMD AM3/FM2 mounting bracket on the left and the new AM4 water cooling bracket in the right. We can see that the new AM4 version has support for a different CPU mounting config as well as AMD's older AM3/FM2 sockets, confirming the previous rumours that AMD's AM4 socket would use a 90mm x 54mm mounting configuration.

Right now we do not know why AMD has decided to change their cooler mounting configuration with their new AM4 socket, though it does mean that AM4 users will either need to purchase new CPU coolers or upgrade or modify the mounting systems for their existing motherboards.

Given current evidence, it seems clear that AMD's AM4 socket will require new CPU cooler designs or upgrades to existing mounting solutions, which means that 2017 will be a busy time for all CPU cooler manufacturers.

Will be interesting to see if corsair will do a free upgrade, considering all their AIO out thereQuote

Anything using the old AMD clip mounting system could still work (the clips don't move that much), hard to know ATM.Quote

Only ever used Intel with mine so not sure what's in the box, will have to go find it in the recesses of the cellarQuote

Well that sucks, unless CM has a mail in adapter I might have to get a new cooler if I upgradeQuote

Noctua will usually mail you new brackets for free for new stuff.Quote
