24C/75F room temps ambient. Could this be why my CPU is always hot?

My room runs 75F/23.9C all the time, very uncomfortable. Is this
likely the reason my CPU NEVER goes below 35 IDLE and All the way to
65C using non-gaming software like simple spreadsheets and word
documents?

Can someone come up with a solution, other than a room a/c or
adjusting the thermostat, to my heat issue?

I tried pointing a box fan at the computer case and it made no more
than .5-1C difference after nearly 2 hours.

thanks

Yes it is the reason why it's so hot. How much it cools is relative to
ambient air temperature.

Without going into serious water blocking type stuff and using gases,
you can't improve what there is without lowering the room temp.

That's not hot.

That depends on the CPU, case, airflow, case fans, background processes,
etc etc etc

Remove + reapply thermal paste, improve case airflow, better HSF unit,
CPU that runs cooler, etc

Hi Robert,

Rule number 1: Don't trust CPU or GPU temp sensor values in software.


Here's an experiment for you...

If your PC has the ability to "Sleep" (in other words it powers down but
will instantly return to the desktop if you move the mouse etc) put it into
this powered down state and let the PC cool down to room temp (over night is
good to be sure).

The object of the test is to load up your temp reporting software as quickly
as you can after an instant power up.

Now look at the temps that are being reported, I bet they are way higher
than the ambient temp and certainly higher than you could heat a CPU in
about 5 seconds, so the secret is to see what the difference is between
ambient and a cpu that should (by the time you load temp software) only be a
few degrees hotter. If you were to deduct this difference (margin of error)
from your original readings you probably wouldn't worry.

Also, when doing this test, continue to let the PC warm up to normal levels
and instead of looking at the temp reading, focus on the amount the temp has
risen by.

One last thing, although it's wise to keep an eye on the temp of your rig,
unless the temp has an adverse effect (ie GPU artifacts) why focus your
energy on reducing it?

Hope this helps

What concerns me is this:
If I load a small word documents and, using my arrow keys, scroll up
and down for under 30 seconds my CPU temp will go to nearly 55C!

I find this odd considering MS Word shouldn't be that taxing,
especially just scrolling a document???

I'll try you experience when I get the chance, thanks.
