During the migration to P3Dv4, I noticed that I can overclock my i5-4690k CPU to get a little more performance out.
Therefore I had to change the CPU cooler to take the stonger temperature of the CPU off.
I decided to use a Thermalright Silver Arrow IB-Extreme cooler. Its a monster 🙂 But in Windows idle I get now around 27°C, before it was in the mid 30°C.
With overclocked to 4GHz I get around 50-55°C with Prime95 and 100° Processor performance.
