AMD AM3/AM4/AM5 CPU Block

This FormulaMod Classic Edition water block fits AMD sockets AM3, AM4 and AM5. The high purity copper base plate is nickel plated for corrosion resistance. It targets builders assembling a custom loop for AMD platforms. Buyers needing Intel socket compatibility cannot use this block.

49 Micro Channels Under Load

Up to 49 micro waterway channels distribute coolant across the cold plate. The dense channel array maintains steady flow during extended thermal loads. Consistent contact pressure from the mounting hardware keeps temperatures stable. Loops with very low pump pressure may not fully utilise the channel count.

5 V A-RGB Interface Limits

A 5 V addressable RGB header on the motherboard drives the lighting through the included sync cable. Without a compatible header or separate controller the LEDs remain dark. The block itself adds no extra USB or software control layer. Builders without 5 V A-RGB support lose the lighting feature entirely.

Questions about this item

How much heat does the 49 micro channel copper base add to the loop during all-day use?

The 49 micro channels in the high purity copper nickel plated base spread heat quickly into the coolant, keeping loop temperatures stable under continuous load.

Does the 5 V A-RGB lighting work without a separate controller?

The block includes a 5 V A-RGB sync cable for motherboard headers; a separate controller is only needed if your board lacks a 5 V addressable RGB header.

Will the AM3 AM4 AM5 mounting fit my existing AM4 loop fittings?

The block supports AM3 AM4 and AM5 sockets with the same mounting pattern, so existing AM4 loop fittings align without modification.
