To hot?

[Jakemaster]

Umm, guys, I think I might have a problem.  According to speedfan my CPU is at 47 degrees Celsius.

Thats bad, right?

Oh, and the fan is at max speed.  I think I need a new fan

[ctjoyce]

Well its not bad, but not the greatest.47C is what I get when at about 50% load.

ATI (x800 and up) will safely run @ 80-85c. I agree it is best to keep them below 70. The critical temp (point of no return) on the newer cores is 110c.

Yep. In many reviews they go past that.

[ctjoyce]

Ya but when they review them, they are looking for the cards limit. Not what you would be doing for everyday use.

Look into a Zalman, atleast replacing the thermal compound.

Is it bad for it to be at 51C when the CPU is only at about 10% or less load?

I need a new heatsink and fan....

Ambient room temp + case airflow + CPU cooler = temp

My room temp right now is 70F and the system idle but 100% overclocked is as follows:



Notice the fan speeds... There are actually 2 tower fans hooked to one motherboard fan port (less than .6A). One on the back of the tower (120mm) expelling air and one on the side (80mm) blowing into the tower toward the CPU cooler. Because of how low I run them and their internal bearing design, they are literally silent and barely heard even at full speed. I run the CPU fan @ 1200RPM at idle and max it at 2000RPM under full load using its in-line speed controller and Speedfan.

Full load after an hour or more of stress nets a 45c-50c temp depending on the ambient air temp of the room but absolutely maxes at 50c. It usually runs about 46c and in the winter, hardly makes it over 44.

EDIT: Here is a sample after running 3D Mark 05 - and - Prime 95, at the same time, looping for 30 minutes:



My PSU also has a thermal controlled fan. Below 42c (internal PSU temp only) the rear PSU fan runs but is quite silent. Above 42c (which it has never seen that temp) a 120mm secondary fan inside the PSU kicks on. At that point it sounds like a vacuum cleaner but it has never reached 42c so the large fan remains off.

During heavy load use it takes about 30 minutes to an hour (depending on the ambient room temp) for my case temp to rise to 25c and kick the main tower fans up. Once they come on it reduces the internal tower temp to 24c within a minute or so. From that point on the tower fans cycle their speed until the load is dropped.

I would highly recommend the Zalman CNPS9500 AM2. It was redesigned from the original CNPS9500 LED and the clip is universal for AM2 or 939 as long as the 939 heat sink bracket on the motherboard has the original AMD HSF clip retainers (not broken off). Also, for the rear of the tower, what makes the Zalman CNPS9500 AM2 work so well is having the right fan on the back of the tower. I use a 120mm Scythe with a Sony fluid dynamic bearing controlled by Speedfan. The more air you move the better the CPU cooler efficiency. If you use large fans @ low RPM they can do the job VERY quietly.

Remember, it

I like to play with a venerable racing game called Grand Prix Legends (when patched to current, it rocks, even though it's from the past millennium) and this is the only game I've found so far for which Cool&Quiet must be turned off because it causes stutters.

Didn't the stock X1900GT get to 87degrees ingame?

[ctjoyce]

Yes, and if I remember right, ATi has since changed the cooler on it.

Ouch.

I don't care what they post at harware review sites... yes, the cores are designed to run hotter but not because the manufacture expects the core to run @ spec, but because gamers are running thier hardware fast and HARD for longer periods of time and the games demand more.

The manufactures designed more headroom into the upper limit to keep the life of the card within a defined window. Anyone running a card @ 85-100c for extended periods will see a reduced card life as compare to running it @ 70-75c.

Unless one is seriously overclocking and pushng the absolute limits of the card, it is overkill to keep a core at or below 60-65c under load. The cards will easily maintain the manufactures designed (usefull) lifespan running @ 70-75c.

For Jakemaster and anyone else who may need it:

Requires an AMD64 processor...

Description:

AMD Athlon

[Jakemaster]

I installed the new driver and went into BIOS, but there was no option for AMD Cool'n'Quiet....

I've had a look on Everest but can't find anywhere that tells me the temps of my GPU.  (GForce TI4600 128MB).

How are you guys checking this?

By the way I found 2 tweeks on here, the omega driver and the FS-GS website had a free download, I'm hugely impressed with my fps.  Found in Tweaking and overclocking.  FS-GS : http://www.simviation.com/cgi-bin/yabb/YaBB.cgi?board=tweek;action=display;num=1145053560

What motherboard are you running?
