recently my CPU has started to over heat, not when it idles, but only when I start playing any game. When idle my CPU temp is around 40 but when I play a game it goes up to 95+. Here's a screenshot when I have a game running in the background of all the temps and voltages of my system. I clean the dust out very frequently so it isn't because of fans being dirty, and I also put on new thermal paste between the CPU and the stock cooler because I thought that might help but still nothing. This only started happening the past couple days so im not sure whats wrong. Also, my CPU is only around 50% CPU usage when it reaches these temps. Any suggestions?

Picture below is when a game is running



Picture below is a couple minutes after I exit the game

Hi,

If you had the computer for at least 3 years, I would first try to reapply thermal paste.
If it's bad quality, it has become solid thus not doing the job properly.

That sounds like your cooler isn't fully seated.

I know stock coolers suck, I mean they are horrible, but 90+c is abnormal even for the crappy stock cooler.

Still using the stock HSF? If so, it might be time for an aftermarket HSF.

In my experience, the stock HSF's plastic weakens/deforms over time and three years is about when it can no longer provide sufficient force for efficient heat transfer. Everyone I know who has used Intel's stock push-pin HSF has run into thermal problems around the 3-4 year mark. These HSF appear to be engineered to only last long enough to cover the CPU's warranty.

He already replaced the TIM

How much thermal paste did you apply? Too much can be just as bad as not enough.

I can't see your pics at work, so sorry if this is answered there, but what CPU do you have? I see that you've re-applied thermal paste already. How old is this PC? Is the fan still running well, or has it begun to bind and slow down? You may need a new cooler.
If you do not overclock, a 92mm tower should be sufficient; if you [want to] overclock, you'll probably want a 120mm or 140mm cooler (if it will fit in your case).

The CPU is an i5 2400 so no overclocking or at least not much would be my guess.

Ah. Well then, the stock cooler "ought" to be sufficient, or would be when new, and assuming the case has decent air flow through it. Do you have your fans arranged to create a flow through your case (e.g. front to back), or are they all exhaust?

yeah i have a phantom 410 with two 140mm fans up top blowing out, a 140mm fan in front blowing in and a fan in back blowing out. Since its been over heating though i took off the side panels so it could cool down better and had a stand up fan blowing into it from behind to cool it some more.

I put about a small pea sized amount on it.

Yeah seems like i need a new cooler, any suggestions? I don't need crazy since i don't overclock, just something that'll work

A 92mm tower cooler will be sufficient, and cost less than a 120mm model.
This Zalman: http://www.newegg.com/Product/Product.aspx?Item=N82E168... costs $5 less than a comparable Coolermaster ($10 less if you play the rebate game and win), making it a much better deal.
