Amd phenom x2 555be overheating

[jatin]

the cpu is overheating (+90 degree C) when i play games(any game).i do not overclock and my cpu fan is also fine.
i hav installed an AMD HD7750 recently and due to this overheating all games lag after the cpu crosses the threshold mark of 77degree celsius.

*VERY IMPORTANT*-i use an asus EPU tool to switch b/t three modes (max power saving,max performance,automatic).
i noticed that in max performance mode Assassins Creed brotherhood is playable at 50+ fps for about 5 to 10 min without lag. after that the cpu temp reaches 98degree and the game starts lagging, also fps drops to 35-45 (this is with every game). BUT, in power saving mode AC was playable at 18 to 3O fps without lag [cpu temp remained <70 degree].
i hav also installed two cabinet fans along with the graphic card.

my system specs are-
umax 450w psu
cpu-amd phenom x2 555 @3.2gh
2gb ddr3 ram
asus M4A88T-M motherboard,win7 ultimate 32bit Add a reply Add to the list of quoted messages Quick edit Edit this message

did this overheating start after you installed the 7750?

If not then reseat the cpu heat sink and apply new thermal past.
if that doesn't work get this

Sounds like the heatsink needs a reseat. You might have accidently moved it abit while installing the card, so its not making a full contact.

Until recently I had the same CPU, overclocked to 3.7, all 4 cores unlocked, and the thing never got past 70C. As others have mentioned, something is wrong with the CPU/Cooler interface or the fan isn't spinning up as temps start climbing.

Remove cpu/cooler and clean them up (remove dust), reapply new thermal paste don't use too much though.
