I ran a program called ATI tool that showed my temperature easily going 95C+ and I'm wondering if that's uber bad?

Every once and awhile I'll get a little bit of artifacting in Company of Heroes after a long game. I just installed CoD2, though, and I get it so bad the game is almost unplayable. It runs fine for about a minute and then it just all goes downhill from there.

I've recently stopped running the AC and the room temperature is around 90F, but I don't know if that is the problem or not?
I've never tried Overclocking or anything like that, and CoD2 used to run perfectly on maxed out settings.

95C is VERY bad.

It seems to be at 74C just right now, posting on the forums. No, wait, went up to 75C.

95C for your video card?

Your fan's dead, turn off your computer and don't use it until you can fix the problem.

Jeez. I have warnings go off at 70, let alone 95, jesus.

omg 95C, hahahaha!! i'm surprised your graphics card isn't asploded.

I took out the card and blew it all out with my air can. There was a lot of dust in the fans. When I started up the PC the video card temp was 50C, and right now it's 63C... 65....

Ugh. What is a normal video card temperature under no stress? 66C. It's getting progressively hotter.

[70... no... 71...]

60s-70s is okay. 80s-90s is bad.

95C = imminent death. 80-90 you can get away with on full load, on some cards, though it's far from optimal. 90+ at idle is asking for trouble. I'd get a new GPU fan ASAP. And don't run any games, if you do use the card at all.

Actually GPUs can survive into the 100-110 range sometimes, depends on the make and brand and individual GPU. You're thinking AMD CPU death range.

It's idle at 69 now, and I have the air conditioning/fan on. I think having a 90 degree room temperature wasn't helping it.

Well I have an X1800XT which runs pretty hot, and it's only idling at ~57C. I'd order a new fan, before you run any games again.




That's true, but I'm not sure you'd actually want to run them in practice past about 90. It's like running a CPU at 80C. Sure, technically it might live, but do you really want to risk it? At the very least your reducing it's live by quite a bit. Also, I was thinking that he was idling at 95C. Load could have been 120+ in that case.

If I use ATI tools to turn up the fan speed, I can bring the temperature way down. Waaaaay down. Is that a perfectly 'okay' thing to do?

[edit]
58C and dropping when I set the fan speed to 60%.

[double edit]

When I first started messing with this it was extremely hot out. 114F outside, and my computer room was literally 90 something degrees. Would that have made a big difference with the video card?

It probably wouldn't make a huge difference, assuming your machine is well ventilated, but it can make a difference. A few years back there was really hot summer over here and my machine kept conking out randomly because the processor was overheating, which turned out to be a mismounted heatsink and no airflow. I don't think there was any damage, but I digress. I don't think there'd be a problem at running fans full-speed, apart from perhaps noise and probably extra drain on the power supply, but I doubt the latter would be a valid concern if at all.

And for the record, my graphics card has an alarm at 115 degrees centigrade. And my processor has one at 85. But since this case has fans up the wazoo, that shouldn't be a problem.

If your room is hot, your PC will be warmer. For instance, if my room stays about 68 my CPU stays at about 32C. If it's at like 80 it stays at about 50C or so.

Weird ****.

Coming from a GPU that ran at 100C under load, this is not something worth dealing with.

And the saddest part is, the card's fan was running 100% fine at max speed the entire time and it still got that hot. I had to actually underclock it.

wow 95 degrees is hot. I don't know what my card is running at as theres no temp monitor, but It's got a fancy huge fan on it (because I had to replace the stock one and it was the only one i could find to fit a 9800 pro).


My CPU is unbelievably cool. The CPU is actually the coolest thing in the room. A few weeks ago my CPU was running at 23C while the room temperature was 29C... which was surprising since I had attached a 80mm fan to the stock heatsink with cable ties.

Now I have a 'proper' heatsink it runs at 24C idle... which is warmer than my bodged attempt. I think I must have scraped off some of the thermal paste when I was forcing the new heatsink on.

I think your thermometer is reading incorrectly >.>

No, because before I cable tied a fan onto the heatsink I wanted to change the bios options (and see if i could have it idle without getting too hot..) it heated up without a CPU fan.

The CPU itself is a 939 3000+ and the HSF is rated for much faster CPUs.

Also, my system temperature is barely above the temperature of the room most of the time, so that helps too.

I know the temps so well because I have a abit uguru board and the uguru clock which tells me cpu/sys temp and the room temp.

You do know that it's physically impossible to get the CPU cooler than ambient temperature unless you use vapochill, or something.

With water or air cooling your just dumping heat from the CPU into the environment, but if they are the same temperature, heat does not transfer.

I have 2D fan speed at 60% and 3D speed at 100%. There's really no sense having your 3D fan speed at less than 100% if you intend to take everything out of the card like modern games would require. Otherwise it's waste of money, and you might have as well bought a cheaper and less powerful video card in the first place.

What?

That's like saying something outside can only be as cool as the static air temperature. Every hear of wind chill? The same thing applies with fans (to a much lesser extent).

This has absolutely nothing to do with the cooling of a CPU. And even if it did I would argue up and down that there's no way for that CPU to ever achieve a cooler temperature than ambient air from air cooling. It just isn't possible with today's CPUs.

Also, it is VERY common for thermometers on motherboards to simply just be wrong, either reading far below or above their actual temperatures. Some software may even read the thermometer values wrong.

grats, you get an F in thermodynamics.

your heatsink works by convective heat transfer. simply, this heat transfer is directly proportional to, among other things, the difference between the ambient temperature and the temperature of the surface, in your case the room temp and the heatsink temp respectively. when this difference becomes 0, you have no net heat transfer. so like obi said, you cannot cool your CPU to a lower temp than the ambient temperature unless you have some sort of heat pump or other cooling implements such as Peltier, liquid nitrogen, or phase change cooling.

windchill is essentially just people feeling colder than they would in same temp still air due to the reduction of the thickness of the boundary layer on their skin due to wind. wont go into further explanation as im lazy, there's a dna gel i need to take care of real soon, and it might honestly go straight over your head...
