Does anyone have issues with their temp sensors?

According to HWMonitor and Realtemp, my 930 D0 @ 100% load, clocked to 4Ghz runs at 100C! It idles at around 55 -60C, but when i put prime 95 on it shoots to 95-100C. The strange thing is that its fully stable and will run hours on end if I wanted it to, but im slightly concerned and im wondering if the sensor is faulty?

I have a Corsair H70 cooler, with 2x120mm fans in push/pull, with the fans on full blast. Ive remounted it a few times with no change in temp
