Hey, this is a weird one and has me very confused.

When I turn on my pc my GTX 560 Ti it overheats instantly and my fan turns on to overdrive to try cool it down. Every diagnostic program I've tried (SpeedFan, MSI Afterburner and FurMark) tell me the Graphics card is running at 233 degrees.

Now, the weird part..

I sent it to a repair guy in my local area who cleaned it out, replaced the thermal paste and did stress tests. He said to me there was no overheating at all and everything was fine. The second I turned the PC on at my house it told me it went straight to 233.

Could it be something wrong with my end? I'm using a mini HDMI to HDMI into a Samsung HD TV.

If anyone had any ideas, it would be great because this has my head really spinning.

EDIT UPDATE:

Just off the phone with a different repair guy who says the readings were not accurate yesterday ( giving something close to what I am getting ) but the machine has no problems and is not running anywhere near that tempture.

It looks like a broken heat sensor, is there anyway to bypass that sensor so I can set a quieter fan profile? It is unusable at the highest fan speed like it is now.

I believe you are right, and it is a sensor problem. The plastic on the cards would have melted long ago at that temperature :) 

Try a fixed fan speed using MSI afterburner to sort the noise issue?

I would suggest getting the sensor fixed though, its there since it is needed.

I cannot change the fan speed through afterburner, or any other tool I have tried. Everytime I try change it, it instantly returns back to full power because it thinks it is at 233 degrees.

Is it easy/cheap to repair a sensor or should I just start looking for a new card?

I'm starting to think it is a deeper problem than this though because I went to play CS:GO today (A game which before hand I would get 100+ frames easy) and I am barely getting a steady 30 on the lowest settings.

According to EVGA Precision my GPU Clock speed is idling around 5/20/50 Mhz with a Temperture of 233 degrees and a 4000rpm fan speed...Not fun.

Sounds like a mix of bad things.. if it is not under warranty and a fix costs more than 50$ i would invest in a new one to be honest..
