i just bought the new Compaq Presario CQ62. when i am doing regular things on my notebook is gets extreamly hot. the bottom left side near the fan burns to touch and the fan puts out air hotter then a hair dryer. could this be something wrong with my computer individually or the entire model of computer. any info will help... also should i invest in some type of a laptop cooler? thanks

When buying a laptop I always advise the person to "invest" in a decent laptop cooler. As each model differs some run hotter then others.
I have no experience with the model you referenced but I do know that a cooler "should" help alleviate some of the heat. I've made my own in the past using a USB connector and 4 fans with a Lexan top and sides. its a wee tricky figuring out what wire does 5v though.

 :welcome: Mcgannon

While this isn't really the most ideal place for this to be a first post, here's what I got...


I have been through a dozen or so older laptops and a handful of them have had cooling issues identical to this.

What I do is I disassemble the entire laptop and remove the CPU cooler. You can find a disassembly manual on google. The TIM (Thermal Interface Material) is usually a fabric pad coated with thermal compound. The pad is a pain to remove from the cooler without scratching the heatsink, but I use a product called ArctiClean (a specially formulated solvent for TIM) and q-tips. Once clean, I apply the thermal compound called "Arctic Silver 5", which uses microscopic silver flakes in a silicon paste which is non conductive (but messy) and has excellent thermal transfer properties. When I overclock I use this product and it helps to decrease CPU operating temperatures by 10 - 15 degrees F cooler compared to a standard thermal pad.

This not only helps to keep your lap cooler, but it also keeps under load temperatures lower due to quicker heat exchange between the CPU and the heat sink cooler. If you really want to make your lap comfortable, you can search for a tri-mount (three screws) 30mm fan that will fit the heatsink but with a higher RPM rating to evacuate the heat from the heatsink quicker.

Check the thermostat, probably got a 195 degree in it now, go down to a 185 and see if she cools down any, if it still overheats it may be the radiator or head gasket.  :lol: lmao!

I think someone has the wrong forum... lol Seriously though, try posting your question here http://h30434.www3.hp.com/t5/Other-Notebook-PC-questions/bd-p/General
