I had just recently purchased a Cooler Master Hyper 212 EVO, and I'm getting higher idle number than my STOCK COOLER. I did install arctic silver 5's thermal paste. Do I have to wait until the paste thins from heat? Anyone have this experience? I'm on base clock 3.5 GHZ on an i5 4690k.
I'm going to guess that you may have used to much thermal compound. Remove your cooler and clean it, leave your cpu in the socket. , You can use a credit card or business card to scrape the bulk of it off then cotton balls or a microfiber cloth and isopropyl alcohol to clean it. Keep cleaning until your cloth/balls stop getting dark. Repeat the process for your processor with it still in the socket. You only need a line about the width of a piece of spaghetti up the center of your processor. You don't need to spread it and you don't need more. Also make sure you installed it right, watch this video.
