hey all,

To test some temps of my fx 8350, i ran prime95. after running for about 15 minutes, the temp stayed at 64 for about ten minutes. What i npoticed was that two cores (core 4 and 6) were not working in the test and that prime95 shutted down the cores. after i closed it i saw that they did work again. Was this stopping because of the temps?

ambient temp: 25~30 (heatwave in netherlands)
idle: CPU 35-40
stressed: max 65 (borderlands 2 ultra = 54)
package temp idle: 14
package temp stressed: max 51 (under prime 95) but i noticed under borderlands 2 that some cores got a max that was about 190 degrees 0.0 still average temp was 37 for each core after playing for about 1,5 hour

i have a scythe mugen 4

well i tested a little more and i found out that in amd overdrive, those where the max temps but then again, they were 99% off the time under 50 degrees and when they reached those high temps, they were about 1 sec on it, i think when al tabbing to the game. I also didnt notice any decrease in performance when playing so i think its a faulty read or something?

also, you think my temps are good or to high for my ambient temp (+-28)? meaning the overall temps (idle 35-40 and stressed max 54 (cores idle: 14 and stressed max 47))?
