I got the A8-3870k and the stock heatsink sucks really really bad, when I play games like minecraft, the temperature jumps up to 60-70. On idle it's about 10-30 degrees. I really need a new heatsink so I don't damage the cpu. Are these heatsinks good?
The first one would perform similar to the stock cooler.
The one i suggested, more than the stock cooler and the first one in your list, read the feedback section on the page.
Would the one you suggested fix my overheating issue? When I'm gaming I get up to 60-70 degrees on the cpu, also when I get my new graphics card, would I also need more fans for the graphics card or is it ok?
Yes, it should perform way better than the stock cooler.
The GPU should be good already.
Hey, all my other stuff in my system is also overheating, my hdd is at 50-60 degrees, my motherboard volts is high also. Everything is overheating, do I need more case fans? I have a stock rear and stock sidepanel. What else do I need?
Put your hand near it, if you can feel air going on your hand then its blowing out, also you can check by putting paper or tissue near the fan.
On the rear fan I can feel a lot of air coming out so it's blowing out obviously but the side panel, I put my hand on the outside and I can feel very little air blowing out, very very little, but I still feel it. I don't know about the inside though.
