What is the ideal CPU temperature

by WheelerCub / October 8, 2008 2:08 AM PDT

Does anyone know where I can learn what the ideal CPU temperature is? I've heard 45 deg C when not being used and 65 deg C when heavily active.

I've been annoyed with my fan running at 80% all the time to ensure that my CPU stays cool. So I just lowered it to around 65% and now my temperature hovers around 65% when I'm gaming.

I want to make sure I'm not going to blow the darn thing up.

Thanks ahead of time.

Without knowing exactly which CPU you're running and what
by VAPCMD / October 8, 2008 12:57 PM PDT

heatsink fan you're running...kinda difficult to provide any further response. Download and run CPUZ...then repost specifics.

Well I'd say anything below 50 C is good for most processors
by damasta55r / October 8, 2008 2:40 PM PDT

I still have a prescott p4 3.6ghz and it idles at 52-57 C, but than the local temp is in the high 80s F. My P4 has gone up to over 100 degrees celcius, w/ no fan because for some reason, the automatic shutdown failed on me , and nothing happened to the processor...I'm using that computer right now to type out this response. Highly not recommended to try at home.

I didn't realize that utility actually tells you the temperature. Thanks again

What is the ideal CPU temperature
by thomson2008 / October 9, 2008 4:25 PM PDT

I have just completed the setup of my new vista HTCP. I am using the il-90mv. Core 2 Duo 2 Ghz. Nmedia 200A case. Install went pretty well, I even got the Viiv software installed and working correctly. My issue is the CPU temp. The nmedia case has two temperature sensors that display CPU and Case temp on the VFD.The CPU temp starts around 75 F and within 30 minutes heads up to about 93F. It will then stay at 93 F for as long as I have it on.

Don't Confuse Fahrenheit for Celcius
by Shun4rm323 / October 16, 2008 5:55 PM PDT

If those temperatures are in Fahrenheit, then it should usually be around 35^C for 75^F and 40 to 50ish for the 90s. I'm just guessing these conversions but I assure you if those are fahrenheit and not celcius then it is fine

Who told you 45^C?
by Shun4rm323 / October 16, 2008 5:51 PM PDT

I have an Athlon 64 3200+ Venice on socket 754 (its ancient but it works for me along with Vista) connected to a Thermaltake Golden Orb II with no fan control but running at 2200RPM tops and Arctic Silver 5 grease. It is very good if it runs 20^C but anything under probably may be sensors incorrection up to what you said. Anything higher, you should probably turn off the machine and check if the heatsink is properly attached or if the Thermal grease needs to be wiped and freshly applied. If there is no grease but a tape, buy a small pack of Arctic Silver 5 which is usually around 5 bucks and apply a bead size or a specific amount that Intel/AMD recommends.
Whoever told you 45^C needs to do some more research...
