Are my CPU's temps. too high?

[Synomenon]

System is in my sig.. I recently switched my board out for a new B3 version. When I removed my H70, I had to clean off the stock thermal compound (it supposedly had some pretty good Shin-Etsu). I used Arcitc Silver ArctiClean 1 & 2 then 100% isopropyl alcohol to clean off the H70 and the CPU. When I put the H70 back on, I used Arctic Cooling MX4.

My CPU (all cores / threads) have been at 100% utilization now for 1.5 hours. The ambient temp. in the room my PC is in is ~25C.

AIDA64 is showing these temps. right now:
Core 1: 52C
Core 2: 53C
Core 3: 58C
Core 4: 52C

Are these temps. too high?

No, they are fine.

Overclocked?

What program are you using for stress testing?

Regardless, they look fine to me.

The only thing I have to load the CPU is BOINC (the distributed computing program for various projects). I'm not overclocking. Just running at stock speed and have Turbo Boost enabled.

prime95 will show you the max your cpu can get, but BOINC is pretty good at it.

your cpu can get to about 100C before it throttles itself and i believe its 120C before it sends the thermal kill signal

Your temp is totally fine.
