Help with temperature on GPU

[Merrill_1]

I recently replaced the cooling fan on my XFX Radeon 5850 card; I ran HWMonitor after I installed the card and to my horror, I saw that the temp was 128 C and the fan speed exceeded 4600 rpm! Has anyone encountered this before? I took it apart and re-applied thermal paste thinking it may have been applied incorrectly, to no avail. I am running Windows 10 64-bit OS, ASRock 970 Extreme MOBO, and 8 GB DDR3 RAM. HELP!!!

Did you replace your fan 1:1? Did you damage a sensor, do you have a Infrared Laser Thermometer ?

May sound stupid, but did you mount it with the air flow towards the chipset.

I replaced the fan with an aftermarket fan purchased from eBay; we tried a different card in the MOBO slot and it read a normal temp,so I don't think the sensor was damaged. The air flow is correct, as the exhaust is coming out of the rear vent of the card. No, I not do bot own an Infrared Laser Thermometer. The card is apparently running cool though.

It's the sensor on the Card that may have taken dmg not on the mobo.

OK - I wasn't aware there was one on the card. I would imagine since the sensor on the card was apparently damaged during the fan switching, there's not much recourse in repairing it, is this correct?
