A couple of days ago when Syndicate launched, I noticed I was getting really abnormal temperature readings, my CPU was spiking into the 80s (Celcius!) b/c of that damn game. At first I thought it was the game itself, but I noticed my temps getting high in games that are considered to be optimized well (as well as idles in the high 30s) but I had never really needed to look or pay close attention (system never shut down or anything like that). I decided to go ahead and get a cooler (I was on stock AMD prior). I got it today (CoolerMaster Hyper TX3) and while the thing was an incredible pain in the ass to install because of the stupid AMD retention bracket and just in general cumbersome-ness, once I got it on that same game that gave me a prior high of 82 C, gave me a high of 45 C and idles in the 20s which is normal for me.
When I took the stock AMD cooler off, I noticed the thermal paste was terrible (I havent changed it in over a year), so that likely was playing a part in someway. I applied new paste and finally got the cooler installed after about 45 minutes lol. Needless to say this cooler is a great purchase so far. $20 and comes with everything you need. I dont care about overclocking and my case is smallish so I didnt have a lot of choice, but the TX3 was well regarded. So thanks Ubi, for making the game a beast and opening my eyes a bit.
