Used this processor for only around 3 months before upgrading to the 9950x3d. I upgraded my build from an extra small SFF build (<5 Liters) in the Velka 3, to a larger build in an ncase m2. This processor works BEAUTIFULLY underclocked and even with a tiny cooler and a 90mm slim fan, while still killing it at every game I needed to run. If you want a processor that is extremely efficient in power and heat, this is the processor for you.
