its a bit warm, but not that mind blowing, check the cpu cooler for dust.
You could also try Aida 64 stresstest instead of prime95.
Hi Mistery. I tried to run AIDA64 stability test but it was stopped because of a hardware failure. Don't know what that means, though.
Edit.: I managed to run the program successfully. Stressed CPU, FPU and cache 30 minutes. CPU socet temp 56 and CPU core temp 44,8. Btw, I'm using Thermalright HR-02 Macho rev.a. cooler.
