Better than expected
Used on a Radeon HD4850. before: -idle: 65-70 C -load: 100-115 C. after: -idle: 25-30 C -load: 40-45 C. Runs quieter and obviously cools better than the stock fan. Most people were stating they were getting 20-30 C drops. i got 40-70 C drops, which is ridiculously worth the money. As for the installation, it was relatively easy, and I'm not the most handy person. My motherboard didn't have another fan controller, so i had to get a 3-pin to molex adapter to connect it directly to my power supply. I have nothing bad to say about it except it may not fit in some peoples' cases as it's fairly large.
