MEASURING TEMPS IN YOUR MAC
A cool CPU is a happy CPU. I’m actually wondering if there’s any quantitative data showing the benefit of a cooler CPU versus minimal power consumed by running fans a bit faster.
Reduce processor voltage to reduce clock speed
ThermographX (no update since 2008, doesnt’ see all temp sensors, but does graph)
TemperatureMonitor (free, current)
Shows values, can store history as well.
iStat Menus (now pay), MenuMeters (free), Matias iRizer (portable stand)
Podium CoolPad and Traveler CoolPad http://www.roadtools.com/index-2.html

Be careful if the little rubber “feet” fall off your laptop – replaced my lost one with a penny taped to the bottom of my MBP!
Even if you’re not experiencing a heat-wave, it’s worth monitoring your temps and fan speeds anyway. If they begin to creep up over weeks or months, your machine may be full of fluff and crap! I vacuumed out my G5 iMac because it over-heated and always had fans going, now it runs much much better.
(Side note: UPS protects computer equipment against brown outs and possible power surge during heavy peak power use times.)
CABLE MODEM ISSUES DUE TO HEAT
Many cable modems offer a status page here:
(nice if your cable modem isn’t locked down)
**Some important figures are**
Receive Power Level and Transmit Power Level (in dBmV)
Downstream/receive should be between -15 and +15
Upstream/transmit should be between +5 and +58 (below 50 is best)
Another important figure is SNR (Signal to Noise Ratio) may not be available, have to break out the big guns to get this value:
This is a Java program that will extract many values (via SNMP I assume) that web status page may not make available.
Run from command line:
docsdiag -jar docsdiag.jar (-vvv)
SNR should be 30 dB or higher, mine is 34.5 right now.
There are also error figures
SigQu: received without error = 1737538425 codewords
SigQu: correctable errors = 106961 codewords
SigQu: uncorrectable errors = 9387 codewords
I was told if the last two values steadily increase, this can also indicate an issue.
