FX-4100 Overheating Issues

[disfear]

Hi Folks!

I could really appreciate your help. Recently I've got an FX-4100 cpu with an asus m5a78l-mlx v2 mobo.
Since last week it worked well, i could ran CPU intensive application for several hours with nearly 100% of load. But now whenever i use the CPU for 10-20 minutes under (or nearly) @full load it reaches 70-75 degrees and counting (i use the stock cooler -i know its crap, but really these are too highs even for the stock fan- , no OC, all default bios settings /v 902) and finally it shuts down. I tested it with prime95 and had the same results...(monitored with coretemp and hwmonitor). GPU temps are correct.

Some tipps what could've possibly gone wrong? (didnt had these issues for 3 months...)

Yeah that seems high as it should only max to 70c. I would check the heatsink and make sure it is locked down tight.

To add to chistop's statement, clean out the dust with compressed air. Did you build the PC yourself and you did apply thermal paste? (I know it's a stupid question, but I have to ask)

no, a local retailer shop had built it for me..hope they did everything well....i checked the heatsink it seems mounted properly, and its quite clean...

However there is a new issue (dunno if its relevant to the case): when opening CoreTEmp (latest release, not beta) sometimes the system shust down, and i get the following BSOD report:

For the record: i dont OC, all the BIOS settings are auto (maybe they shouln't be?)
