Super Easy install, ive never modded a cooler and was able to get this installed myself. Reset the fan curve if you are running in a MS A2, and make sure to take out the port cover on the shell. Mine runs at 79-81C at full load for extended times and that's where it tops out which is fine by me. Such a unique setup for a small but powerful rig that's running at around 200 watts at full tilt. Perfect for running offline agentic AI. 10 out of 10.

Hey there, i wanna say that i really love companys/people who try to make modifications like that on Cards like that. I am honest, i was struggeling a little bit because i ran into some problems. I have remounted already a lot of Cards in my life so i want to make it real. There are two major things i would like to point out. 1.: The included Thermalpads for the VRAM chips are a litttttle too small. I had too less pressure on it so the temps on the VRAMS went to 120° degrees real fast. But i solved that by putting another very small layer of pad of my own. After that it was fine.
2.: On the Original Cooler of the card there are two important power stages (near the fan) what are not cooled by the copper cooler. What i believe are important to include. Also there are no Thermal pads for the front power stages of the cards where i also had to use my own and trying to find the right size. The screw holes are not perfect, they are "okay". But i do understand that it is hard to make a product like that and still trying to make a profit out of it. So still will give it a 4 out of 5. I really would like a 2 slot cooler for this card what makes it really chill. Sadly that one is not in stock.

I love it anyway and will be happy to try another product of you guys again one day.

Best regards
