Guild Wars 2

everytime i turn supersampling ON fan starts to get real noisy and when i checked my MAX temp it hits 77 degree celcius,(we only have 2 seasons where i live) and im worried since were close to HOT seasons coming up.
but after 5 minutes when fan finally pick up the pace the average temp 65-69 C. but like i said its real noisy.
is supersampling works like this on your pc? does it going to damage your gpu if this happens for regular playtime 4hours+ everyday?
sorry for my imperfect english and thank you first for replying ^^

This is quite normal, nothing to worry about. Super-sampling increases the load on the GPU by a significant amount and so, because your GPU is working harder, the temperatures will increase. Thus, to keep it cool, the fan speeds up. 77 degrees is actually fine for a GPU under load and 65 is a perfectly fine temperature. You can, if you really want, lower the fan speed with a tool like MSI Afterburner, but I wouldn’t recommend it, it’s obviously keeping itself cool on the current settings. Just make sure it doesn’t increase too much more.
If the noise is bothering you, check your case’s airflow and remove any dust build up inside the case including around the fans.

“Supersampling is computationally expensive because it requires much greater video card memory and memory bandwidth, since the amount of buffer used is several times larger. A way around this problem is adaptive supersampling. This works by acknowledging that very few pixels will actually be on a boundary, therefore only these need to be supersampled.

At first only a few samples are made within a pixel. If these values are very similar, only these samples are used for determining color. If not, more are used. The result of this method is that a higher number of samples are calculated only where necessary, thus improving performance."

Q: Doctor, doctor it hurts when I do this!

A: Then don’t do it.
