Fedora Core 12 x86_64, kernel 2.6.32.19-163.fc12.x86_64 (just updated via yum).</p>
<p>At idle, with nothing running in the foreground, the CPU is around 70-72° Celsius, and the other sensors are 80°+.  Why is this?  It seems like every time I run yum update the machine gets hotter.  I wonder if there&#8217;s any way to figure out what&#8217;s causing this.  In any case, it&#8217;s pretty annoying.  It&#8217;s uncomfortable putting the thing on my lap for any length of time.</p>
<p><a href="http://evanhoffman.com/evan/wp-content/uploads/2010/08/why-so-hot.png"><img src="http://www.evanhoffman.com/evan/wp-content/uploads/2010/08/why-so-hot-286x300.png" alt="" title="why so hot" width="286" height="300" class="aligncenter size-medium wp-image-570" /></a></p>
<p>Notice the temperatures at the top.  The first two are Core0 and Core1, the other 2 are other sensors.  The CPU is running at 1.0 GHz due to SpeedStep and the temp is still 70°C.</p>
<p>Edit: I forgot I&#8217;ve been logging temperature via sensord.  I just turned the computer on after having it off all night and within 10 minutes the CPU is back up to > 60°C.</p>

Bluetooth worked fine under Win XP.  The computer is an HP/Compaq nc8430.  When I go to the Bluetooth control panel I get &#8220;Your computer does not have any Bluetooth adapters plugged in.&#8221;  The weird thing is, sometimes I&#8217;ll see the bluetooth logo in the taskbar at the top, but then when I look again it&#8217;s gone and I have no idea how to get it back.  When I booted it up this morning I noticed the icon was there so I ran some of the debugging tools for Bluetooth and checked dmesg and this time at least it looks like at least there&#8217;s proof that Linux CAN see the Bluetooth adapter, I just don&#8217;t get why it then stops recognizing it after just a minute or two, and a reboot doesn&#8217;t even consistently bring it back.</p>

<p>It looks like it worked until I turned on wireless via the hardware switch.  But even if I start up with wireless off it doesn&#8217;t work.  Hmm.</p>

Pretty sure it started around the time I put antivirus on it, which reinforces my theory that antivirus is a virus itself.  Anyway, being bored with Windows XP and having already played with Windows 7 at home, I decided to install Linux.  The last time I tried Linux desktop was around RedHat 7.3, which was a long time ago&#8230; pre-Fedora even.  I&#8217;m pretty happy with CentOS on the server side and was set to try CentOS 5.3 on my laptop when someone suggested I go with FC due to more bleeding-edge driver support.  Even though the hardware is pretty old at this point I figured it was worth a shot.</p>
<p>Generally everything works pretty well.  Everything pretty much works out of the box &#8211; I had dual screens up at native resolution, it even recognized my phone as a camera when I plugged it in to charge it.  Best of all, I was able to resize the NTFS partition (rather than blowing it away) so I can still boot back to XP when the need arises.</p>
<p>There are 2 problems I&#8217;ve had so far though:</p>
<ul>
<li>the computer now hovers between 76 and 85 degrees Celsius, whereas under Win XP it generally peaked around 68 C.  I tried underclocking the CPU down to 250 MHz but the problem persisted.</li>
<li>The Java plugin for Firefox &#8230; wtf?  How can this not work?  I downloaded Sun&#8217;s JDK and symlinked the libjavaplugin_whatever into /usr/lib64/mozilla/whatever/ and that didn&#8217;t work.  Then I tried &#8220;yum install java-plugin&#8221; or something like that and that installed some OpenJava-ish plugin which looked like it was going to work, but when I logged into the Raritan KVM and clicked &#8220;Connect&#8221; it wouldn&#8217;t work.  I booted up Win XP in a VM and Firefox with Java works fine.  Really annoying and dumb.</li>
</ul>
<p>I&#8217;ll probably try Ubuntu tomorrow as several people suggested it runs cooler than Fedora.  If that fails then I guess I&#8217;ll go to Win7 after all.  I also want an SSD for my work laptop now&#8230; my Windows VM seems to spent eternity spinning my crappy 5400 rpm drive.  <a href="http://www.newegg.com/Product/Product.aspx?Item=N82E16820233087">Plox</a>.</p>
