Question Is it normal for my i5 8600k to be at 35c while idle?

[Joefy]

My CPU temp currently is 38c is that okay for being idle

I have a i5 8600k

Yes, that is a perfectly normal idle temperature. How warm is the room the PC is running in?

38c is completely fine. I think it can get better with good airflow but it's still fine. Nothing to worry about.

Currently my room is at like 50 degrees

 

[COLGeek]

50C or 50F?

50f

50f

That is a very cool room. 38C is a normal idle temp, as previously stated. Please describe your airflow, number and types of cooling fans, make/model of heatsink.

NOTE: Your thread title says 35C and the posts 38C. Which is it? Either is fine, BTW.

120mm fan with a pure. Rock slim cooler

Effective cooling is about airflow. Typically, front, side, and bottom fans pull cool air into the case. Rear and top fans exhaust the hot air from inside the case to the outside.

Having a single fan is not efficient. You should consider using (at least one) a front intake fan, along with the rear fan (that I assume you have) providing exhaust to help move air through your case better.

The Colonel is correct, however, something doesn't add up ...

50°F is 10°C, which is indeed an abnormally cold environment for operating a computer.

The standard for "normal" room temperature is 22°C or 72°F. Normal idle temperature shouldn't exceed 10 to 15°C above ambient.

IF "idle" is really idle, which means only 1 or 2% CPU Utilization in Windows Task Manager, then in a 10°C environment, idle Core temperature for a desktop computer should only be 20 to 25°C.

Obviously, there's some additional information that we're missing.

Either your ambient temperature isn't accurate, OR, "idle" isn't really idle and is instead a light load, OR there's a cooling issue such as thermal compound failure, or an improperly mounted air cooler, or an AIO liquid cooler with a flow problem.

Regardless, idle temperature is a poor indicator of thermal performance, and can be very misleading. This raises other question such as what your load temperature is when running which software workload using which monitoring utility.

Please provide more detailed information.
