What's a "safe" case temp?

Sometimes mine gets up to 40 C. Is this okay?

Barely within limits (42C). Case temps shouldn't be more than a few C more
than room temp. So unless your room is 98F I'd say it was way too hot. My
current case temp is;
CPU Temp: +33°C (low = +15°C, high = +55°C) sensor = diode
M/B Temp: +28°C (low = +15°C, high = +40°C) sensor =
thermistor

I can't get near those temps Wes. I suppose a lot of it is the choice of
case. Mine has those small holes over the fan inlet/outlets, restricting
air-flow. I've been tempted to Dremel them out. Likewise I can never get my
AMD 2600+ core temp below 44c at idle, 50-ish at load, no matter what I blow
on it with! :-((

That's the first thing I do to a new case before I ever put anything in
it. But I just use a big pair of diagonal cutters and and then drill BIG
holes in the front plastic cover to replace the samll holes. if they
aren't any holes, but slit vents are something like that, I just start
cutting the plastic out til it doesn'y restrict airflow. makes a huge
difference. Depending on the case, the back is usually ok, but I've still
had to rework a few of the backs too,

50C diode temp is fine under load. But that will drop too if you get the
case temp down from 40C to about 30C.

Thanks. The case I have is a Jeantech Butterfly V2. Ever seen one of those?
It does have handy removable sides so I can get everything out that way if I
start drilling!

Depends a lot on how the case temperature is being measured. The "case
temperature" for my K7D used to be very high because the sensor chip sat
right in the path of the air from my graphics card. Some are even positioned
in the airflow coming from the CPU fan. These would read much higher than
one way down the "bottom" of the board, or one sitting directly in front of
an intake fan. Only way to be sure is to get a (calibrated) thermistor on a
wire and stick it in a known position of the case. In front of an exhaust
fan is probably a good place.

I have drilled all sorts of holes in my cases too, just to parrot Wes's
advice so don't be hesitant. Some cases have no holes in the front, just an
opening at the bottom of the front of the case. If the case is not mounted
on feet or sits on a carpet that opening will be blocked.

One test is to pull the front or side panels off the case and see how much
the temperature drops.

The other factor is extra case fans. My systems at work usually have 3 or 4
case fans. I like to have cases fans designed to deliver fresh air to the
CPU, N-, and S-bridges and an exit fan at the back. The main inlet fan is
an 80 mm.

Just remember the extra fans will add to the noise level, but it doesn't
bother me any. It is just white noise in my office. However, you should
see all your temperatures drop, which means that you can crank the voltages
up to get better speed and stability.

Best wishes,

Pete
