PC connected to LCD TV | Graphic Card Temp > 55 | TV Screen Blinking

[anoopaythala]

I connected my PC(DVI-I) to my 52'' LCD TV (HDMI)(Sharp "LC52D65E") . My tv has a full HD resolution (1920×1080).
My graphic card is ASUS EAH4350 (ATI Radeon HD 4350 GPU)
I have now a Full HD view in my tv.

I have the ASUS SmartDoctor installed in my pc to monitor my graphic card.
This software displays the graphic card temperature.

I can see that when the temperature is above 55 deg cel.
My tv screen starts jumping , jerking sometimes even blinks or blacks out.

Is 55 deg is really over heating ?

Is there is anyway to resolve this ?

Was that at idle or while playing games? Even at idle that's not exceptionally hot for a fanless 4350. More case cooling or a fan on the GPU might help.

Get a 75mm fan that plugs into the motherboard or uses a molex plug then mount it near the videocard.There are also aftermarket heatsinks for GPU's.

Of course, he probably bought that particular card because it was silent.
