All else being equal, a CPU with a lower TDP wattage will be cooler. That's not to say that they can't warm up ... the heat sink, fan, and other thermal management aspects still come into play too.
... After researching my problems, I was surprised to find that the radiation and heating from laptop is really bad for my health....
...
How do I reduce all this heat comming from the keyboard and touchpad????Should I try the HARApad???
On the HARApad website http://www.harapad.com/, there is a link to a document (http://www.harapad.com/pdf/bio-initiative_exerpt.pdf) written by Ms. Cindy Sage, Sage Associates, titled Summary For the Public, in which are outlined supposed dangers of electromagnetic radiation from many types of wireless devices.
"Despite the overwhelming scientific evidence against the view that our electronic gadgets are causing our headaches, nausea, Alzheimer's, or stress, there are organized movements in several countries to enlighten the world about the dangers of EMR. In the USA, there is The EMR Policy Institute. There is also something called The Bioinitiative Report, a website registered to Cindy Sage of Sage Associates, an environmental consulting firm located in Santa Barbara, California."
mrgrape, if you are concerned about heat I'd consider the pads offered here, http://www.overstock.com/Office-Supp...6/product.html. They are a bit on the small side but will lift the laptop from the table, providing ample room for air circulation, thus reducing heat.
You didn't mention how technical you are, I am assuming by your talk of radiation probably not very but you might find this advice useful anyway. Even though you used canned air to blow out the fan there may still be dust stuck in there. Canned air actually sometimes makes the problem worse because it pushes all the dust into one ball that might completely inhibit the fan from moving. You can do one of two things:
1. Pull your fan out completely and make sure there is no dust blocking the actual vent. This requires disassembling the laptop at least partially. Usually need to take the keyboard off or the bottom casing but it really depends on the laptop.
2. Take it to a local repair shop and ask them to do it. Make sure to tell them you want the fan removed, blown out and the vent cleaned as well. How much that costs really depends on the shop. I always do it myself so I really have no idea. If you go this route ask them to check the thermal grease on your CPU as well.
How old is your Lap Top? Get a riser pad. Keep it raise to allow air underneath.
Since 1993 it seems like I go through computers every other year.
My last 3 laptops....two Hewlett Packard 17"s, and a Gateway 7". I use with two external hard drives. A 500g and a second 2t.
The first HP 5yrs old, died due to a bad daughter board. Call HP, they wanted $250 to repair it. It's sitting on my self, thinking about trashing it.
The 2nd HP 4yrs old HP, still works but gets really warm, even with a riser pad. Last year took it with me to an evening collage class. It barely fit on the desk.
Ended up buying a 7' Gateway 250g to take notes. Comes in really handy at work and school, due to it's small size.
Lucked out last week with other computer - they were trashing a 2006 Dell Desktop at work. Took it home bugged it out, found bad sectors on the hard drive. Brought a new Sata 500g hard drive, and upgraded the ram to 4g, tweaked both the registry (regedit) and my Firefox browser (about:config).
Have a fiber optic internet connection, pay an extra $10 monthly to my ISP for extra speed. On the wirelesslap tops when I downloaded music, programs etc, the best speed was 2.5k MB per second. Now down loading speeds up to 48k MB per second,.....
I got a gadget that my wife's laptop sits on. It has fans blowing upward, to keep the puter cool, thereby increasing the age of the laptop. She has another computer in the living room, an "all in one," I think they call it. Looks very nice and it may be cooler than a laptop.
BTW, I really like the idea of a separate keyboard and mouse. I wouldn't have it any other way. You just have to change the batteries now and then.
You can try opening up the back panels on the laptop and blowing air underneath the motherboard to clean out any potential dustbunnies that may have gotten lodged in there. The crap I blow out of some clients computers is nothing short of frightening.
Otherwise, laptops in general are going to get warm. It's the result of shoving a bunch of electronics into a tiny box, putting ONE ****-poor fan into it, and calling it good. This is why I like Desktops. 12 fans and I still ***** about cooling.
Anyway, if the heat bothers you from the keyboard, try using an external keyboard, and if you want, look up a docking station or port-replicator for your model of laptop, and turn it into a sort of desktop base-station.
