ARCTIC Freezer 4U-M - CPU Cooler Server for AMD and Intel, 4U & Up, 2 x 120mm Fans, 400-2300 rpm, 4-Pin PWM Connector, 8 Heat Pipes

This is a great 4U cooler that has a proper orientation for the SP3 socket. Installation is easy. Fans are quiet.

Got an Epyc you want cooling? Get this cooler. It’s the right orientation, it’s easy to fit and it’s quiet.

Extremely well cooling my system, only my case won't close, and dust was building up pretty fast. It could be perfect at 100mm tall or some...

Installation for sTR5 was a little unintuitive (since I didn't watch the guide first) but once I figured out how the screws needed to be installed through the mounting bracket and into the heatsink it was a breeze. The adjustable fans really help with ram/vrm fan clearance too, this cooler fits my Asrock trx50 ws perfectly with just the front fan shifted up 3 or 4 cm.Overall, this is a great heatsink at a competitve price

Orientation of the cooler isn't optimal on this board, you'll need to raise one fan because it conflicts with the heatsink on the motherboard, you can't really use the first pcie slot because it will block the fan intake/outtake.
