Cpu and System temps

My CPU speed is a solid 38 degress C, but, to my surprise, the system's temp is 52 degrees C! This is without any overclocking.

Isn't the system temp usually around 28-38 degress C? What could I do to decrease this temperature? I have a full-tower case with 3 fans.

Well, there's always liquid cooling, or if you're daring (and crazy to a degree) you can replace the liquid in the system with freon (or the legal substitute).

I always liked the idea of mounting a window air conditioner nearby, then building a duct to pipe the cold air directly into the front of the case. Or putting the PC inside one of those small refrigerators. Or building a PC INSIDE a small refrigerator (but condensation could be a problem!).

Anyway, case (i.e. system) temps are always difficult because of the case volume. Typically, there is only one sensor and it's on the main board. It may be at a local hot spot created by congestion of cables and "stuff". The actual inside temp might be ok. One thing I've done is to get a outdoor digital thermometer from Radio Shack and put the probe at different spots inside the case.

First thing is the basics. Make sure some fans are blowing in and some blowing out. Make sure the inlet openings are not blocked - sometimes these can be drilled larger. If the inlet holes are on the bottom of the case, raise the case above the table or carpet. Maybe re-arrange the cabling, if possible.

And your temps don't seem too far out of line to me. Right now, mine are 42 CPU, 44 board, and 50 in the power supply. This is a tight Shuttle case so it tends to run hotter than some.

I'd just add that you should try and get a nice air FLOW through the case. Which can be difficult if you have a crappy case!

This case has got AIRFLOW:

There's a link on that page to more pictures and instructions on how to build one.

Try this little monitoring program, you can set alarm levels and fan speeds. Its a nice free program.

Make sure your cables don't block airflow in your case. It's easy to have hot spots because cables are shielding some components. Also check the fans on the mother board, many use fans on the bridge chips. I have found fans that won't turn. Take the fan off, pull the paper sticker off the midle of the motor and put a drop of oil in the bearing work the fan around and try to free it up. I have even removed the clip holding the shaft and pushed the shaft out of the motor to clean and oil it. This will often quiet a nosy motor too.

My solution

1:Buy Mini fridge
2:Plug in Mini fridge
3:Put computer inside Mini fridge

This way you can always keep your computer temperature at around 4*C
