Solved SystemCooling-Is my graphic card overheating?

Specs: Windows 7 Ultimate x64, 2.793 GHz / 2047 MB
Processor: Intel Core 2 Duo E7400 @ 2.8Ghz
RAM: Kingston 1 x 2GB DDR2
HDD: Seagate 500GB SATA
Graphic Card: Elite-Group nVidia9400GT
Motherboard: ASUS P5KPL-VM
PSU: Don't know about the make but its a 450W with a 120mm fan inside the case sucking air in and one on the outside blowing out.
Operating System: Windows 7 Ultimate x64

Recently my GPU fan started making noises so I removed the card and gave the fan some oil. It was full of dust so I cleaned it and did the MISTAKE OF TAKING OF THE HEATSINK. I ruined the thermal paste on it. I just put everything back together and the noise was gone. I did not apply a new paste.

Now I sometimes have garbled image while watching movies. I mean its distorted and gray or black and gets stuck and then starts playing normally after awhile. I thought it was my graphic card that it was overheating so I checked the temperature using a software called SpeedFan. It showed a temperature of 56C and a fire sign beside it telling me it was hot otherwise all other temps had a green tick by their sides. From what I know graphic cards can handle temps upto atleast 100C. My PSU is the only cooling I have which blows hot air out. It is loacted at the top back of the case other then the CPU and GPU fans.

My CPU temp is around 50C-53C. I'm in Pakistan so its extremely hot here nowadays compared to the US. I just came back from the US last week. I was in Little Ferry, New Jersey and compared to that place it is extremely hot so I think the CPU temp is normal. During winters it comes around 38C-42C.

So is their a problem with the card. Should I consider getting a Antec Spot Cooler for the card and any other additional fans.

Waiting for a response.

More fans aren't the problem. You didn't reapply the thermal paste to the heatsink. You can try removing it and applying some arctic silver, but you may have damaged the gpu. You'll never know until you try it.

Okay! Applied a standard thermal paste from Cooler Master which I got for 1.5USD and it did not work. Although I got the fans because they were going to provide cooling to the system as a whole. I got three fans.
1> For the rear to blow out.
2> For the front although this lies horizontally below the HDD and not vertically at the front due to no space given to attach a fan.
3> On the side panel. There were 2 locations at the side panel one was in front of the CPU and the second one was in front of the graphic card so I chose the spot where the graphic card was located.

The fans worked and the problem is gone. Temps went down really good.

CPU: From 53C to 47C
GPU: From 56C to 49C
HDD: From 46C to 40C.

Anyways thanks for the help.
