Is 13 Celsius normal for a PC? Or is the program wrong?

Hello Users of Tom's Hardware,

So I had done some Prime95 tests on my PC today, the specs are as follows:
FX-6300 (Stock 3.5 Ghz) (Corsair H55 Cooler on the CPU)
Gigabyte 78LMT-S2P
8 GB Ram
Rosewill 500W Cool PSU
2 HDDs
Radeon 7850 2GB
And a Cougar Solution Case


I had done the tests because I had no fans in my computer before, which had led to high temperatures, so I had installed 3 extra fans. In the Cougar case I installed 2 in the front for blowing air in and 1 in the top for pushing the air out, this was the recommended areas for the fans on their website. The Prime95 test concluded that the max my system temps went was 35 C (or 95 F ), however my temp program said my PC at minimum usage had a temperature of 13 Celsius ( 55 F ). I'm curious to know if the Temperature program was wrong, can a computer even get that low in a home that is about 80 degrees Fahrenheit?

Thanks, JP

download something like coretemp and check with that as well. You can compare with games running or programs to test the temps

Yes it can get very low. on idle my cores get at 7C with my Corsair H100i.

Your first reading of 35 C is your CPU die thermal sensor. the 13C may be your core temp Sensor. those two differ but they normal get around th esame value when cpu loaded

And your minimal temps mean before the test started. look for your max temp.

never lower than ambient temp is the rule without refrigeration. Idle temp 10-15 degrees C above ambient is considered normal. Third party programs are often wrong and believing something lower than ambient is ignoring a possible problem.

No. Sans refrigeration cooling, 13 degrees centigrade is not a normal temperature. The laws of thermodynamics still apply inside of a PC case which means that thermal energy will always flow from a high temperature volume to a low temperature volume. It is not possible for an air cooled heat generating device to be at a lower temperature than the ambient environment. This means that unless your PC is cooled by refrigeration, phase change, thermoelectric or some other exotic method it will never drop below room temperature because doing so would violate the laws of physics.

The cpu is cooled by a H55 Corsair Water cooler with 2 fans cooling the mini radiator.

Doesn't matter what you are cooling it with, unless it is a TEC or liquid nitrogen your CPU temp HAS TO BE greater than your room temperature.

It's a botched reading, most likely faulty software or faulty motherboard firmware.
