Graphics temperature is not high, sometimes Huaping Why?

I am referring to run and play with proe3.0, it is sometimes, not always.
Sometimes used proe3.0, in the area there will be a drawing of a line that looks very out of sorts.But sometimes This will not be.
Graphics temperature:46 degrees, run from time to time to play around 53 degrees.
This is what causes? Help you, who's Canadian.

with the refresh rate may be related to the monitor refresh rate that try to raise the quality of the graphics will not do, if it is installed, then the main will be more likely to have This issue.Graphics have been normal 70 degrees temperature
you simply do not have to worry about the temperature
problem is the quality of your graphics card is not good, or is the graphics chip does cause a problem.But it may be contact card Have a look at the impact of dust capacitance is not the drum, as soon as possible to change on the capacitor can be, if the warranty period, a direct seller to find another experience it should be a hardware problem is to see if you have not capacitance The Bao Diao?
Or wiped down
golden touch may be the problem of driver issues ~ ~ ~ may be a long time, the failure of the circuit, the heat is not high, may be a low-voltage, I suggest you Try down.Graphics suggest that you use high-temperature good chassis or power supply fan
Huaping.But for graphics drivers.So either the card failure.It the best memory, graphics cards, CPU .Removed, it re-inserted.And then re-driven.Generally can get.There you will be able to set up BIOS.Optimize the value of the load.Oh, do.These are the methods.Hardware failure is unlikely to happen.There is no system could respond to, redo the system is also an option for you.
