I just built my first computer about a month ago.


PSU:
OCZ Fatality 750W

MOBO:
ASRock Z77 Extreme 6

CPU:
Intel Core I7-3770K

RAM:
Kingston HyperX 8GB DDR3 1600MHz

SSD:
Samsung 840 120GB SSD

GPU:
Gigabyte HD 7950 3GB



-My system is air cooled.



I downloaded SpeedFan to monitor my temps and noticed an icon next to my CPU and GPU temps that looks like a "Flame" assuming this indicates its too hot!

Both my CPU and GPU are idling at 50c.


When I open a game or put my computer to work somehow, the CPU jumps up to around 75c maybe even 80c but only 20% usage! The GPU will go up to 55-60c.




Are these temps too high? What can I do to lower them?

Your idle temps seem a little hot. Your load temps on the GPU are fine. Your load temps on the CPU aren't technically out of spec, but they're a good deal higher than I'd like. Anything above 80C is generally troubling unless it's a one-off overclocking experiment or whatever. Personally I start to get a little agitated well before 80C.

How hot is it where you live? Have you cleaned out your case? Do you have filters on your intake fans? Have you overclocked at all? Upped the voltage? Have you double-checked the installation of your CPU's heatsink, made sure the heatsink's fan spins properly?

that sounds about normal.

my 2700k will idle at around 30 degrees with a complete custom water cooling loop
the 3770's will be a little hotter because of the change in TIM on the top plate of the CPU. not to mention added transistors and smaller die size.

these CPU's are stable until the 90's mark. I wouldn't worry to much about it. your cpu fan will be running as slow as it can (to keep noise down) to maintain a normal operating temp. the more you work the computer the faster the fan will run.

I dunno, man. I'm looking at idle temps of about 30-35 C with the stock air cooler. You obviously have a much beefier cooling setup, but water cooling generally doesn't (or shouldn't) lower the idle temperature by an awful lot; water just dissipates heat better than air.

In other words, a custom water cooling setup should lower your max temps by a fair amount relative to stock air cooling, but it shouldn't lower the minimum temps by all that much. Water can't make the CPU cooler than the ambient temperature, for instance.

So my rambling point here is that your water cooling doesn't explain a difference of 20C between your idle temps and his. Unless the OP is sitting in the middle of a desert, I can't imagine that everything on his end is completely kosher. Should he worry? I would, but as you say, his temperatures are still technically within spec. The question is how much longer they'll remain so. The OP only just built this rig. If the CPU cooler isn't installed correctly, for instance, his temps might be a sign that it'll fall off later. Or if his chassis has inadequate ventilation now, imagine how it'll be after dust builds up for a couple of weeks.

But you're right: his CPU isn't going to die immediately because it hits 80+ degrees. Caveat Emptor, YMMV and all that jazz.

I live in wisconsin and this has been the first week or two now that the temps have reached the 70s so I'm worrying that my computer will start getting even hotter once the summer gets going.

The computer is brand new like I said and there is like no dust what so ever. I havn't overclocked or did anything like that. Everything is just stock.
