Aluminum Heat Radiator Heatsink Cooling Fan 150x85x12mm Blue Tone

I recently got a Asus Strix 3090 to game and to mine and I bought a corsair waterblock. With the original air solution on the card, my junction temps ran at 92c, which is a little hotter than I like. Once I put the waterblock and backplate from corsair and added a slim 120mm schyte fan on the back, my memory junction temps went down to 80 to 82c depending on the room temp. Now with this heatsink. I placed to strips of double sided thermal tape I had around, placed the heatsink right on the back on top of the memory spots and placed the slim 120mm fan on top and now my junction temp went down to 76c! I am extremely satisfisfied with the heatsink. Although is slightly smaller than I like, but it does a wonderful job at cooling my card

Helps dissipate heat from my power distribution box

I put on my KVD7212nx controller and it has reduced the heat.

Issue with high memory/Vrm temperature for the RTX 3080 FE? Not with this heatsink. Make sure to add thermal pads between the pcb and the backplate. Dropped about 10C at max load.

Used it on my GPU as a passive heat sink, got a 2C drop, not much but cannot complain at 6 bucks.

The dimensions were exactly as described and fit perfect

Now the aluminium itself didn't do much on its own, i placed a fan on top of the heatsink pushing and pulling with no meaningful difference in memory temps. But adding fans underneath the gpu, which are noctua a9's btw, lowered temps by 7c on core and 2c on memory temps. The heatsink is placed on top with 1mm thermal pads and it does get hot to the touch during timespy stress test. I would say putting fans underneath the gpu is the way to go, but this heatsink will probably work better for non founders edition cards as those backplates tend to dissipate heat better with vent holes and cut outs. You have to test it out for yourself with a fan pushing air into the heatsink and do stress tests to see real results.
