Graphic card overheating at full Fan Speed

Hello People, summer season is the worst season for gaming and here i am with a new shitty problem.
i don't know whats happening earlier my AMD 6770 used to get 60-70 C while gaming even in the hottest day at fan speed 60 % but recently i have been experiencing a huge temperature increase. I don't know why, while benchmarking it gets to 111 C even the fan at 100 % but i do not experience any crashes or BSOD, My cabinet is not a problem i guess as i have 1 120 mm Betfinix LED Fan for intake and one for exhaust i guess it's sufficient as my rig is not too super duper. i did try removing the heatsink of the GPU and apply fresh paste but nothing's changed it still goes to 90 C while i play crysis 3 or any other GPU Consuming game. All my components are dust free i clean them regularly. Does it means my gpu will die in the coming days please help me guys what should i do to decrease my GPU temperature. i have done everything possible to have a better cooling but still i do not have any temperature decrease. I read somewhere that insufficient PSU may lead to rise in gpu temperature, so is my PSU not sufficient please suggest guys i need help.
Thanks.

Oh and yes my rig

AMD FX 4100 3.6 GHZ no OC
GSKILL Ripjaws 1600 MHZ
ASUS M5A78LXV2 motherboard
Seagate barracuda 1 TB HDD
Corsair VS450 PSU
Powercolor AMD Radeon HD 6770(NO OVERCLOCK)

Well it sounds like your GPU isn't getting a good contact with the cooling sink. 111C is quite hot and shouldn't be run at those temperatures. Your 60-70 C while gaming is good and obviously something change to get you up to 111 C. The PSU doesn't seem like it should be an issue, since you have a decent one, but might need to be looked at in better detail. I would double check your heat sink on the GPU and make sure you are making good contact with the chips. You could also pull off the side panel and see if your temps come down drastically or just a little. This will tell you if there are other parts in the case that are elevating your GPU temps or not.

What case are you using, BTW?

Check to make sure your fan speed is set on Auto in Catalyst Control Center. Also try setting it to 70-80% and see if that helps.

There's an outside chance the GPU fan might be going. If you have an extra case fan try cramming it up next to the heatsink and see if that helps. Ghetto, but it's for science.

Use GPU-Z or another GPU utility to measure temps and fan speeds. Make sure that whatever software you're currently using is giving you good data.

And of course open up that case and see if more airflow helps.

There is no way a normally functioning card should reach that temperature.

Most likely due to some event ( perhaps physical shock? ) the cooler is no longer in good contact with the silicon.

If you are not sure that you can re-seat the GPU's radiator, take it back to warranty.

If you continue using it in these conditions, you will definitely burn it sooner or later.

Hello guys thanks for the replies!
i am using a cheap cabinet which i did mod for extra fans and it's quite large
yes i did try reseating the HS and screwed it pretty tight so that it has good contact and did apply fresh paste.
i was suspecting the sensors have gone awol but i tried to touch the gpu and it was really too hot and couldn't touch it more than 2 sec, it would have burnt my fingers :(  and yes opening the cabinet doesn't have any impact on the temperatures it remains the same. i use msi afterburner it shows 100 C+ while GPU stress test GPUZ shows 90 C +

Bro it's 100 % i.e 5000 RPM shown in Speedfan it makes quite a Jet engine sound
