I'm using a phenom ii x4 965 BE overclocked at 3.8 along with a Hyper 212 EVO and currently with only Firefox opened my CPU idles at 45c. Is that temperature to high?
More abouttemperatures high
It's pretty high. The load temps are what's important though. You should never let it get higher than 62C.
Firefox for a CPU these days isn't anything. IF you're at 45C at that which is basically idle; you may have a heat problem. Have you done any stress testing at all? I'm talking using Prime95 or similar?
Also, have you double checked with more than one software source for temperatures as some applications will differ to different boards. I'd do a little gaming or something a little more "aggressive" on the CPU and watch the temperatures in a couple different applications to make sure they are reporting right. If the load temperatures are getting over 65C then you may have an issue. When I shut off my fans on my 212+ I will idle/browse at about 32C compared to the 68-75F ambient temperatures in the room. If I crank them they drop the temperatures usually within 2C of ambient. So I would make sure the fan is spinning like it should and make sure that you're getting proper readings on temperatures.
If you do have a heat issue here's a couple things to check.
Thermal Interface Material (Bad thermal paste application?) CPU voltage just too much for the 212? Ambient case temperature not close to CPU reported temperature (which would relate to a poor airflow environment.)
Well I just ran Prime95 on blend for 20mins and it only hit 55c.
Edit: Well I forgot to turn off prime95 so its been running for around 1hr now and only max of 55c
Those are really good temps and are what you should expect from an aftermarket cooler.
Thats good, thanks but I wonder why it idles so high =/
What case you have
Thermaltake v6 BlacX, but the top fan has broken. So that could be an issue but I'll be replacing the fan in a week or so.
How is your CPU fan set up? Does is completely shut off during idle? That could be an issue especially if you're running a fixed voltage system. The fans on my 212 can be shut down completely as I have them on a fan controller. If I do some media player with high res movies I can actually get the CPU to hit near 50C without a fan on the cooler running. So I'd check that to see if the CPU fan is set to some stupidly low settings.
Thanks for the help, but I have my fan set to 100% because I'm currently overclocking. But I'll try with OC and see if thats the issue.
Whoops. Overlooked the 45c idle. What are the temps at 100% idle?
