Theoretically, a well designed(air flow) case, can circumvent the need to remove the side of the tower.
Having said that, it is a cheap solution but your personal experience of 10-20c is a massive improvement, and doesn't often work quite the same for anyone else - thus it's not really comparative to LCS in general.
If your GPU temps with a 470 get over 100c then either you're outside temperature is extremely hot, your GPU fan isn't running fast enough or you should put some new thermal paste on.
I've worked on several systems with 470s, and at 60% fan, they idle about 55c and get up to 80-85c with 75% fan.
Awsome game I wish i could get it but parent are fags and they dont't let me get M games.
You didn't call your parents fags
You didn't call yourself "hacker" on the internet
You learned to spell "awesome" and "assassin"
they might think you are mature enough to get the game. -Davidelmo
