I would start with a heat shield and see if that helps. I Had a similar issue where my AC evaporator is 6 inches from an exhaust header. I added a heat shield on the evaporator housing and it helped with AC temp.

While I generally agree with this it feels wrong in this case since everyone who bought it can get a refund.

About 3 years ago I played a CoD during the free weekend and had mostly the same experience as you. What I found to be the cause of the problems is that the starter guns have a much higher time to kill than the unlocked and modded guns that the rest of the players were using. Players know to prefire based on the map at the top-left. The game basically has a built in radar hack. You can camp a corner, aim at the opening, and watch the map to know when to prefire. Players who started playing when the game launched and are still playing have memorized the spawn locations and know where to aim to catch fresh respawns.

If you have a browser that still supports javascript bookmarklets and are brave enough to trust code from a random stranger online I have a bookmarkelet that I got from a random stranger online years ago that cleans all of that junk from links on the entire page making them safe to click.

javascript:(function(){var%20k,x,t,i,j,p;%20for(k=0;x=document.links[k];k++){t=x.href.replace(/[%]3A/ig,':').replace(/[%]2f/ig,'/');i=t.lastIndexOf('http');if(i>0){%20t=t.substring(i);%20j=t.indexOf('&');%20if(j>0)t=t.substring(0,j);%20p=/https?\:\/\/[^\s]*[^.,;'">\s\)\]]/.exec(unescape(t));%20if(p)%20x.href=p[0];%20}%20else%20if%20(x.onmouseover&&x.onmouseout){x.onmouseover();%20if%20(window.status%20&&%20window.status.indexOf('://')!=-1)x.href=window.status;%20x.onmouseout();%20}%20x.onmouseover=null;%20x.onmouseout=null;%20}})();

I blocked the notification with uBlock and just pretend nobody ever reads or comments on my comments. You can say whatever you want if nobody is around to hear it.

Not having a global karma score that is require to post in different subreddits helps too.
