Hey guys,I've been playing Battlefield 4 for a couple of weeks now and I realized that my gpu fan
lowers the spin speed on itself when in game.For example when I set it at 85% it after a while drops to 40% but instantly!First indication of this situation was that the spin sound fainted but on the other hand there was like a small screen lag the moment this happened.Soo my hypothesis is that either the psu is struggling or that msi afterburner has some weird sh@t goin on..
What are ur thoughts?
Oh and here's my PC specs:
-q6700 2.66ghz
-4gb Kingston ddr2 ram
-9600gt 512mb
-350 watt Chieftek
-250gb hdd Maxtor
-Dfi bloodiron board.
