    I have a Lenovo T60 with an Intel Dual Core T2400 (1.83 GHz) processor. I've just installed RmClock to monitor my CPU temperatur. The temperature varies between 45 and 57 degrees celcius even if I'm not doing anything special. Is that normal ?

    If I'n on the Internet without any other applications running such as music etc. then the temperature is around 48-54 degrees celcius. Is that too high ? If I'm just leaving the computer standing in idle the temperature is around 44 degrees.

    Should I be worried ?

    Regards,

    No those temps are perfectly fine. Once they get in the high 80s low 90s, then it's the time to worry.

    Like adinu said those temperatures are completely normal. You can always check out ways to cool your laptop down even more with the cooling guide but it isn't necessary in your case.

    Those temp are normal for core2duo. If you think that is high try using an AMD Turion X2 laptop. Temps on Turion X2 laptops reach 80c and its still normal temps.

    I do and you are correct. Also even though it does not matter my TL max temp is 203 an Intel is I believe 212. So it runs cooler and has a higher max Temp.

    Laursen,

    Out of curiousity, try Core Temp. Link

    My T2500 is around 13-15C idle and rarely ever gets above 42C. I guess I'm lucky... :p

    Really the high temps are your own fault. When buying a laptop the first thing you should consider, is "does it have fan control." You people buy mainstream laptops are brag about how hot they get. Literally its stupid. Your processors like core 2 duo's and Turions have a maximum power usage of 34-40 watts. That is little bananas. My Opteron 185 uses 125 watts of power, and it peaks at 50C, because Clevo designs good chassis and incorporates fan control in their systems.
    If you want your temperature to drop, prop up your laptop or find a program which will let you control your fans.

    I see your point and have no doubts I can do things to overcome but let us be real. AMD's run hotter than Intels (except maybe P4's). That is the only point.

    Yes AMD's do run hot, and when it gets hot the fans spool up, and I know my processor is working. My AMD processor is designed for a 1U server, not really for a laptop, but I have to admit AMD's do run hotter than Intels per util of performance. The turion line runs hot because it was essentially a cheap mainstream line which got better battery life then their athlon series. AMD saw they were gaining a hold in the laptop market, so they sold higher clocked turions, which got hotter because they were based of the same three year old turion architecture.

    Nope, I use a program called i8kfanGUI (most Dell users have it). It allows you to control the CPU and GPU fans. It monitors the CPU (both cores), GPU, HDD, memory, and chipset temps.

    Also to take in mind, I have speedstep/EIST enabled. ;)

    It's showing 20C throttling @ 100% in Vista right now. My 7900GS is at 45C. :)

    I find it kind of funny that you guy's can talk about CPU temps! First of all there is no way your temp can go below the ambient temperature! But some of you guy's do! I mean I know! my Intel runs at 3 below Zero while doing payroll for the company I work for!! Sorry I am done!

    Sci FI Mike, you must have forgot to do the 30F offset.

    If you download and run core temp, you will see that there is a 30C offset with I8KFANGUI.

    Ah, you're right... I forgot that offset....

    Wow that is impressive, I know on my Dell E1505, there is a 30F offset between core temp and I8KFANGUI.

    That makes sense now becuase you have an ultra low voltage processor. Still those temps are very impressive.
    I see that temp graph at the bottom, it is almost as if you are using your laptop outside, or you have the window open.

    Have you ever tried underbolting a ULV processor? is that even possible?

    The man lives in an igloo if those temps are true.

    Na, I live in my basement. According to Vista's Sidebar Weather Utility, my IE toolbar weather thermometer, and my outdoor thermometer; it's 18F outside.

    So, it's probably 60-65F in my basement (with the heater going on from time to time).

    @K-TRON, it's showing my T2500 as ULV cause it's downclocking. For some reason Core Temp thinks that it's a ULV processor rather than a notebook equivalent.

    Uhhh...dude...you do realize that's 55 to 59 Farenheit at idle? If you're on air cooling, you really need to invest in a better heater. I certainly wouldn't want to come to your house if your laptop's running below 60 Farenheit. Brrrr.

    edit: Crosspost. OK, figured you couldn't be in a regularly-heated room. Might want to check your basement temps again - sounds like you're a bit below 60 Farenheit - but at least it seems plausible now. I know my unheated basement can get close to 50 Farenheit in the winter.

    Yeah you're right. It's probably in the 50's but nothing less. Otherwise I would be freakin' shivering to death.

    Hell, in the morning when I'm usually half-naked I'm pretty comfortable down here. And it's usually around 26-30F in the early morning.

    these are good, k8temp reads it using on-die thermal diode(s)

    My Dell E1705 core2Duo runs at CPU temp of 60-62 consistently. Is that normal?

    I thought the fan died until I downloaded i8kfanGUI and brought it down to about 40C. A full 20 degrees lower.

    Question, is the systems thermal threshold working properly? Why should I need the i8kfanGUI program? Or is the a bug in Dell's default temperature control?

    I kind of think 62C that it run at before I installed i8kfanGUI is a bit high. I watched the fan for a while and it just doesn't seem to turn on.
