best slim Heatsink for the price, ideal for small cases :D

Experience: 10 Days
Works great in my GD05 with a 5800k. Keeps CPU at idle around 30-35c (depending on case fan speeds) and load around 40-50c.
Covers a ram slot, so you have to install the ram module first and make sure there is clearance.
Really good cpu fan. Came with all parts that you would need to mount it.
