Temps and graphics

onelifecrisis · 12-07-10, 08:43 AM

I've read many times on the net that "anything over 50C is bad" or similar. It's garbage!

My current PC idles at ~50C CPU and ~65 GPU. During intensive games it runs at ~80C CPU and ~85C GPU. I don't have any extra cooling in it (though I do have to clean dust off the CPU heat sink every now and then or it starts to overheat). My previous PC ran games at ~80C CPU and ~80C GPU and it lasted through five years of intensive gaming (without even being regularly cleaned) before the PSU finally gave out and I replaced the whole rig.

Processors are designed to run hot. Cooler is better, but hot is not actually a problem (unless it gets really hot, like over 90C).

Myeah, technically true. Something like a Q9550 runs up to 70C safely, according to Microsoft's specifications, but it will indeed run much higher without commiting suicide. You can expect impact on lifetime though, but if a chip would last only 3 years instead of 5, it's still likely you would replace it before it fails.

Still, what's the point in burning up a chip if you can get a decent 3rd-party cooler for something like 20-30 bucks? Maybe you can collect the parts left over after upgrades and build a second PC, use it as a server or sell it or something.

Better safe than sorry, right?

60C is generally the so-called magic number for CPUs for everything that I've read. So long as you're under that under load, you should see no decrease in life on the CPU. GPUs always run hotter, but if you start seeing anything over 75-80C, I would start becoming concerned.

It all depends on the CPU type and GPU type. Intel's I7's can run happily in the 70's C while AMD's tend to get really pissed off once they exceed 55 to 60. My gtx 285 GPU often hits around 90C and run stable but much more than that it get s grumpy. It ALL depends on the hardware your running.

This is not true. My graphics card (GTX 260) is designed to keep the fan idle until it reaches 85C, and only then turn up the fan just enough to keep the temp at 85C. In other words it's designed to run hot and quiet, rather than loud and cool.

Think that has more to do with "silent" being the new buzzword than proper design tbh.

Ever since graphics card reviews started including noise-measurements, cards have been becoming more quiet, not always for the best. My 8800 for example was so "quiet" that it would overheat, until i manually set a more aggressive profile.

This true. My PC sounds like an old beaten up Trabant, but for god's sake it works.

Ow and my case is fine example of "silence over design", it has 2 fans, the PSU fan and a 120mm fan on the bottom and the "walls" are covered with rubber foam of sorts to keep it silent. Sure, it's quiet as hell, but it also heats up very fast.

Here's the best part: the case is called "Nexus Breeze"
