CPU Temps Get Hot REALLY FAST When Playing Games For a Few Minutes!

Whenever I play a game my CPU temps get really really hot super fast for some reason.. 80c hot!

The highest I've seen it go is 80 and I was only playing a game for about 10 minutes!

Can anyone tell me why?

Thanks in advance! :)

P.S. I've got a few fans in my PC as well as a stock CPU fan. I don't overclock..
I use CPUID monitor to check my temps.
 
More info will be needed. Even without the info here's a few things you might try.

- Reduce the temperature of the entire room
- Replace the CPU cooler (especially if you're using the stock cooler)
- Replace the thermal paste (go find a guide about applying it properly, many people use too much)

When you give us more info we can help more.
 


I'm not really sure what more info I can give..
Temp of the room is about normal.
PC is brand spanking new so the Thermal paste and CPU cooler are new out of the box!
CPU is running at 4.00GHz

 


I haven't chnaged anything in the BIOS. I had a friend make it for me so I'm not sure if he did,I'm 75% he didn't tho.
I even double checked and loaded the default BIOS settings.
My intel core i7 4790k is at 4.00GHz tho..
 
80C sounds totally normal and expected to me for a 4790K on the stock cooler. I don't see the problem. If you start hitting >95C you have a problem, till then you're fine. You can drop temps 10-20C with a $20 HSF. Just about any 90mm tower with 3 heatpipes will do the trick.
 


That's what scares me tho... the temps don't tend to stay at an idle number,it just just keeps going up.
If I was to keep playing at 80c,it would just keep going up beyond that. 🙁
 
Chart your temps and see what happens while you play. Keep in mind that max cooling demand (highest RPM on the HSF) won't kick in until you're reaching near the thermal margin limits. The higher the core temp, the more temp differential there is, and the more the HSF can dissipate. The i7-4790K should be expected to run right at the edge of thermal margins on the stock cooler, that was the whole point, they pushed as far as they could go on the stock power envelope for the socket.

The chip won't kill itself. When it runs out of thermal margin it will throttle itself. Nothing wrong with that. If you want to adjust the CPU cooling policy you can do so in BIOS. Set the PWM fan control to something more sensitive or to a "performance" mode. This will kick up the fan to higher RPMs for lower reported temps.

If the stock HSF truly can't keep up, the only reason would be that the case is not adequately ventilated for the thermal load. Assuming your GTX780 is the type that exchanges air inside the case (non-squirrelcage fan), then you have approximately 300-400W worth of peak thermals inside your case that needs to be swept away at a good pace to keep the charge air for your CPU HSF at a low enough temp to function properly. If you're running all that with just 1-2 case fans you're going to have problems.

What case is this all installed in and how many of what sort of fans?
 


I have a Zalman Z11 Plus: http://www.amazon.com/Zalman-High-Performance-Tower-Case/dp/B00AC8AF4G/ref=sr_1_1?ie=UTF8&qid=1410266476&sr=8-1&keywords=zalman+z11+plus

I'm just using the stock fans atm.

 


All fans are running but they don't seem to be doing much,my window is wide open atm blowing cool air in.
Played a game for 4 minutes and temps were in there 80s in each core. GPU went up to like 60.
Is there something wrong with the parts because everything is brand spanking new with no dust on them and case has about 4-5 fans (ranging from small ones on case sides and 2 120mm fans in the middle of the PC and a bigger one at the front...think there's one at the back aswell...)

Is CPUID monitor giving me a false reasding?
Should I ring the company I bought the parts off?
 
I have had the same experience as for my gaming rig went up to 90C.
What I did was overclocking using the OC genie button while running with a discrete GPU. From then on I cannot enter windows.

What I did was I removed the dGPU and boot up again and disabled the OC genie function. Now I use the BIOS in OCing.

For your case, try to remove the dGPU and look if the problems solved.
 


This sounds interesting...
Could you give me step-by-step instructions?
Thanks :)
