CPU temps question

post #1 of 4
Thread Starter 
I'm so out of my league here but I figured this would be a good forum to post my question. I have a Dell Studio XPS 8000 I bought like 3 years ago. I recently upgraded my power supply and GPU. After working inside the case I determined that this system was not designed for good airflow...for instance the GPU is on the bottom of the case with the fan pointed down. Seems a strange way to vent hot air since hot air rises. There's a dell stock heat sink, and only 1 92mm case fan blowing air out of the case. There's no place for any other fans. At any rate these are my CPU temps taken using real temp:

Idle: 48c (average)
Max load: 70c (average)

i7-860 CPU
8 GB ram
Nvidia gtx 560 ti
Corsair gts800 (800 watt)

I'm not overclocking are these temps ok? I'm thinking of leaving the case open nd putting a window fan to blow air into the case on when gaming. Is that crazy?

Thanks

It could be cooler, but 70c isn't going to damage anything. Most processors can handle ~100c before they start to fail. As for the graphics card, usually the fan sucks in air and blows it out the back of the case, or out the side of the card, not downwards. You could try adding another intake fan to the front or side of the case if you want to lower temps even more, but if you're not going above 70c and don't plan to overclock then there's no real reason to.

Thanks for the response. Unfortunately with this case unless I cut into it there is no option to add any additional fans. I guess I'll just go with the flow.

Your temperatures aren't horrible with a stock cpu heatsink. But could be better. Like Piero mentioned, GPU fans are directed to blow air onto the GPU. If you can't install any extra fans on your case then my recommendation would be to upgrade your CPU heatsink. Won't help your overall case airflow but will help get heat away from the processor quicker in comparison to the stock heat sink. Some other recommendations would be to buy a faster/stronger 92mm fan and replace the old one, and make sure your PSU is facing so the intake fan sucks in the case air and exhaust it out the back (you probably already set it up like this).

Next step, get this nibblers or a dremel ready =).

EDIT: I saw a quick image of that computer. On the side panel there is a very small section for ventilation at the bottom. You could buy another 92mm fan and mount it against that mesh to intake some cool ambient air. You would have to go a little DIY to mount it but it shouldn't be bad. And if your not comfortable drilling holes you could probably zip tie to the mesh =). You can take out the rear 92mm to test before you buy one. Good luck.
