Q9300 Idle Temperature

Hello guys.

So I`ve got a little problem with my Q9300 Idle temperature. When I turn on my PC and open ( for example Core Temp ) the Min. temperature of my CPU idling is around 45C and that`s only when the PC is just turned on. After like 10-15 minutes, no matter what I do, idling, browsing or any not-cpu intensive actions my temperature stays around 48-56C. Yesterday I changed my thermal paste ( it`s MX-4 ) and cleaned my cooler from the dust ( yes there were some ) and the temperature changed with maybe 1-2C ? I`m kinda worried cause` I think this idle temperature is too high for the CPU. When the CPU`s under load ( for example when gaming ) it stays at around 58-63C. The cooler I`m using is Acer HI.2490C which looks like this -

And here`s a screenshot of my min/max temperature while browsing the internet and listening to a Youtube playlist -

I would like to hear if there are any suggestions on what I can do to lower the temperature a little bit without spending money on a new cooler. Thanks in advance !
 
Solution
increase airflow in your case , which means buying more case fans , this will help intake more cool air or exhaust more hot air or just get a better cpu cooler or both

Are you sure that your CPU is idle? Coretemp shows a CPU usage of about 0-5% (idle) but the frequency is at 2.5GHz (Full load). Task manager is showing some kind of process using all the CPU?

Hello, I have the same issue on my Q9300 with AC Freezer Pro 7. My idle temperatures are the same as posted above, with full load i have on all cores about 70C... I thing, that I have bad contact between CPU and cooler, or I applied too much of thermal paste...?

I did as you wrote, situation is better, but not much. Max. temperatures of cores are about 66C in full load. Overall CPU temperature (Tcase) is 41C in full load. Is it normal this difference between Tcore and Tcase? Idle temperatures are now about 55C.

I tried stock heatsink too (instead AC Pro 7) and temperatures were about 10C higher...!

I am starting to think, that this situation is normal, in addition TjMax. for Q9300 is 100C...

Ambient temperature is about 24C.
