Is my CPU faulty? & there is a fix?!

[Alex78]

CPU is: i7 4770k (Made in Costa rica if this is mean something!)
Cooler: evo 212 plus
Motherboard: Asus Maximus VI Hero

idle Temps about 31c , ambiant 20~24

problem is I am getting high temps. when I run prime95 (small FFTs) test I am getting about 91C in all cores, motherboard automatically overclocked CPU @ 3900 1.28V and if I do the 4way optimization in Asus Ai III suite it will clock the cpu @ 4200 1.328V and I will get 100C with the test!
according to what I read I shouldn't get such temps. on those settings! I re install the cooler and paste but nothing help!
is there is anything to do about this?
Can I live with this temps. since I get them only during the test but in real life when I am gaming for example (BF4 Ultra setting) I get around 60~65C, Thank you

well what kind of cooler are you using ? if its the stock cooler i would not try using it for overclocking. also make sure that you have tightened the cooler down to the motherboard. i prefer a tight fit personally so i screwed mine till they would not turn any more with out excessive force.. it also makes a difference as to how you put the thermal paste on ..

well I would say you might want to consider deliding it but thats a risky proposition. other than that those things run hot anyway. that may be all your going to get short of maybe setting up a push pull config on your cooler adding fans or upgrading them.

you might want to look into h110 or some other liquid cooling loop.

I added an extra fan for push pull but it dosn't really help
