https://www.sourceitstore.com/product/24-q50n1-001/ Definitely not cheap (they also raised the price $10 since my order) but worth it for me since it fixed my heating issue 100%. I had been searching for almost 2 months to find the part #, and then to find a retailer. After some serious googling I finally found the exact part #, and then it took more time to find this company that sells the part. I was a bit skeptical of the website but they listed it as 'in stock' and immediately after my order it dropped to 4 in stock. I actually ordered it from their Canadian version of the website not realizing they had a US store as well. I ordered around the holidays on Dec 19 and because of that it did take a bit of time till delivery on Jan 6. For me it was worth the price because something was definitely wrong with my heatsink. Since I purchased my 2080 Max-Q Triton from Amazon 'renewed' at $1545 out the door I had little to complain about other than the thermals being high. Luckily for me this new one works 100% as it should.
