System getting a little hot

[archcommus]

It's kind of warm today, around 75 F or so, so my room is a little warmer than it has been, but certainly not warm enough to cause these kinds of issues. My CPU's idling around 50 C, and with a load goes to 55+. I have the BIOS set to shut down the system at 60 C and that's what just happened as I was using it to sort some massive arrays in Java.

It's an Athlon 64 3200+ running at stock speed. I have two intake fans with a filter and one exhaust fan. The CPU cooler and fan are both stock. The intake filter does a good job so there is literally almost NO dust inside. What could be the problem?

temps outside prolly...

what does your cpu usually idle at? lower 40s?

In the winter, low to mid 30s. When it's warmer, usually around 40, 45 at the highest idle.

If your intake is higher than the exhaust, this can cause heat buildup. Try turning off one of the intake fans.

Other than what's already been stated, and the fact that your room is warmer than normal, have you checked the filter for dust buildup?

Hmm I never considered that, too much intake is bad I guess when the room is hot. Shouldn't cause a sudden spike like this, though, but it's something to consider for this summer.

I just cleaned the filter not too long ago, currently it has a light layer on it and nothing more.

After it shut itself down while crunching those numbers I waited a bit then turned it back on and ran it for awhile with the side wall off. During that time it was running incredibly cool, like 35-37 C. Now, many hours later, I put the wall back on and it's idling around 37-38 C. True, it's nighttime now, but that's still pretty weird. I've had other cases in the past where it was consistently running hot, and then after a shut down/cold reboot it was running like 10 degrees cooler. I WOULD attribute that to just software inaccuracy, but it's pretty close to what the BIOS reports, too, so I really have no idea.

Haha today it's running at 29 C idle!!
