Aluminum Large Heatsink 5.9 x 3.6 x 0.59 Inch /150 x 93x 15 mm Black Heat Sinks Fins for Cooler RTX 3090 3080 ti Backplate PCB LED Motherboard (2 Pcs)

RTX3080のBackplate接地面にthermal pad はついてないですので別で購入する必要があります。サイズも良くて、作りは安っぽくないです。

LAN10Gハブにつけたら、それなりに冷えたよ

Mining doesn't throttle hard anymore. Prior to this, I'd get 106-110C mem junction temps, at a 200 underclock with 100% fanNow, can bring the ram to +1350 and temps are under control at 100-104C with only 50-70% fans.Used thermal pads to even the gaps out, and rested a 120mm on the back. Temps and fan noise are much better.Packaging was sturdy, wrapped in foam and in a box.

Would be great if it came with thermal pads. Worked well on an FTW3 3090 to cool the rear memory. Used some 1MM thermal pads I had laying around and just set this on top of the pads and applied some pressure to mate them together. Dropped 4K Warzone temps about 8C after an hour of runtime. So far so good.

My pepwave gets pretty hot during use in warmer climates. This adds a lot of surface area and cools it and I attached it using double sided thermal tape also purchased from Amazon.
