Is it normal for my cpu to rise its temp to 96 C when stressed(when its not stressed it stays at 30 C)?I have changed the stock cooler with this one http://www.titan-cd.com/product/showProak8_en.asp?ProID=435 my processor is AMD Athlon 64 x2 5200+ Brisbane (OC from 2.7 to 3.0 , its not that much for heat like that ) Before i was with athlon 64 x2 4000+ and it stayed at 60 C (stressed) and it was overclocked too (from 2.1 to 2.5) and the cooler im using is the same , so do i need to change it or i should get new thermal paste for this one ?

96C is way above where you want it to be. Reinstall the heat sink and make sure to replace the thermal paste. With that small of an OC you shouldn't significantly change your temps.
From appearances, the linked cooler looks to be only marginally better than the stock cooler. The fan is small, and the fin area is not that great.
If your case can accomodate a taller tower type cooler, spend $30 on a cm hyper212 or Xigmatek gaia.
If added or better case fans are an option, look into that. To see if better case cooling would help, take the case side panel off, and direct a house fan at the innards. If temperatures come down a bunch, then work on case cooling first. A good cooling case can be bought for <$50.
